docker部署项目: centos+python+redis+mysql+uwsgi+nginx

一、Centos7安装docker

1.1 环境配置

先测试是否下载了docker：查看镜像：docker images
没有下载，就依次执行以下环境的安装

①curl  http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

②yum install -y yum-utils device-mapper-persistent-data lvm2

③yum list docker-ce.x86_64 --showduplicates | sort -r

④yum install -y --setopt=obsoletes=0 \
docker-ce-17.03.2.ce-1.el7.centos.x86_64 \
docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch

⑤systemctl daemon-reload
systemctl restart docker

⑥docker version  查看版本

二、镜像

2.1 配置镜像加速

直接复制阿里云：Docker-hub：https://cr.console.aliyun.com/cn-hangzhou/mirrors
先创建文件夹：mkdir -p /etc/docker

执行：
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://68rmyzg7.mirror.aliyuncs.com"]
}
EOF

2.2 镜像加速方法

https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

2.3 拉取镜像

从中央仓库中下载镜像到本地
docker pull 镜像名称：版本标签（如：docker pull mysql：5.6）

2.4 查看镜像信息

docker inspect 镜像id 或者 镜像名称:标签

2.5 删除镜像

方法一：先删除依赖镜像的容器：
docker rm 容器id 或者 容器名称
容器id查找：这里docker ps -a 所有容器信息 -q 正在运行的容器ID
再删除镜像docker rmi 镜像id 或者 镜像名称

方法二：强制删除镜像，依赖它的容器会一并删除：
docker rmi 镜像id 或者 镜像名称：版本 -f

2.6 搜索镜像

docker search 镜像名称

三、容器

3.1 创建容器

docker run -it 镜像id 或者 镜像名称:便签
-i 标准输入
-t 伪终端
-d 守护状态运行
--name 命名容器
-p 端口映射(宿主机端口:容器端口)
-P 端口映射(随机端口)
-v 文件挂载 (-v $PWD/redis/conf/redis.conf:/etc/redis/redis.conf)
本地文件/路径:容器文件/路径
不论修改宿主机还是容器内挂载的文件，会同时变化，避免要修改容器中文件内容
而需要安装vim或者复制文件至容器的操作。
-link 容器间通信(--link tesudrm_tsdrm:django_server)
关联的容器名称/id:关联容器服务器地址的别名(自动加载至hosts文件)

3.2 启动容器

docker start 容器id 或 容器名称

3.3 关闭容器

docker stop 容器id 或 容器名称

3.4 进入容器

docker exec -it 容器id 或 容器名称 /bin/bash

3.5 暂停容器

docker pause 容器id 或者 容器名称(unpause取消暂停)

3.6 查看容器详情

docker inspect 容器id 或 容器名称：版本号

3.7 删除容器

docker rm 容器id 或 容器名称(只删除已经关闭或者退出的容器，-f表示强制)

3.8 复制文件至容器

docker cp 本地命令执行所在相对路径 容器id/名称：/root/(容器绝对路径)
如：docker cp /www/pro_tesu/MySQL/tesudrm.sql 容器ID:/root/

四、配置

4.1 准备的文件目录

mkdir /www/pro_tesu/Redis/{conf,data} -p
mkdir /www/pro_tesu/MySQL/{conf.d,logs,data} -p
mkdir /www/pro_tesu/Nginx/{nginx.conf,log} –p

文件夹结构：
www
    pro_tesu
        Redis
                conf
                redis.conf(配置文件，参数见附录)
                data
        MySQL
                conf.d
                        my.conf(配置文件，参数见附录)
                logs
                data
        Nginx
                nginx.conf(配置文件，参数见附录)
                log
        TSDRM（项目）   

4.2 MySQL容器

①创建容器:宿主机3306端口可能被宿主机占用
docker pull mysql:5.6
docker run -p 3307:3306 --name tesudrm_mysql -v $PWD/MySQL/conf.d:/etc/mysql/conf.d \
-v $PWD/MySQL/logs:/logs \
-v $PWD/MySQL/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=password \
-d mysql:5.6

②拷贝sql文件至容器
注：前提是先把sql文件上传到/www/pro_tesu/MySQL文件夹下
docker cp /www/pro_tesu/MySQL/tesudrm.sql 容器ID:/root/
如：docker cp /www/pro_tesu/MySQL/tesudrm.sql 1e373b556bc6:/root/

③开启容器
docker start 容器id

④进入容器
docker exec -it 容器id或名称 /bin/bash 注：容器开启的状态下
cd /root/ 切换到容器的家目录下，ls可以查看是否有sql文件

⑤连接数据库
mysql -uroot –p密码 如：mysql -uroot –ppassword
⑥创建库
create database tesudrm charset=utf8;
show databases; 查看库是否创建成功
⑦注意：导入文件需要在容器的内部，而不是在数据库mysql中执行
退出mysql：Ctrl+D
cd /root/ 切换到容器的家目录下面执行导入sql文件
mysql -uroot -ppassword tesudrm< tesudrm.sql 
进入到数据库中：mysql –uroot –ppassword
use tesudrm；
show tables； 
⑧退出mysql以及mysql容器
Ctrl+D 或 exit

代码示例：

[root@zgs ~]# cd /www/pro_tesu/MySQL/
[root@zgs /www/pro_tesu/MySQL]# ls
{conf.d,  conf.d  data  logs  tesudrm.sql
[root@zgs /www/pro_tesu/MySQL]# cd conf.d/

4.3 redis容器

docker pull redis:3.2

cd /www/pro_tesu/
创建容器:宿主机6379端口可能被宿主机占用
docker run -p 6378:6379 --name tesudrm_redis -v $PWD/Redis/conf/redis.conf:/etc/redis/redis.conf \
-v $PWD/Redis/data:/data \
-d redis:3.2 redis-server /etc/redis/redis.conf

附件的配置文件需要修改：
注释掉127.0.0.1
找到requirepass字段，取消注释，字段后填写redis密码
注意：在 vi reidis.conf 添加配置的时候，要以编辑模式复制进去，不然，容器会创建不成功

五、centos6.8容器下安装python3.5.4

5.1 拉取centOS6.8镜像、创建容器、进入容器

docker pull centos:6.8
docker run -itd centos:6.8 /bin/bash
docker exec -it 容器id bin/bash

5.2 编译的方式安装python3.5.4

官网下载python3.5.4(手动迅雷下载快)：
①https://www.python.org/downloads/release/python-354/
②找到这个文件下载 Files: Gzipped source tarball

5.3 安装软件管理包和可能使用的依赖

yum -y groupinstall "Development tools"
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc

5.4 centos6.8容器中安装安装python3.5.4

①上传Python-3.5.4.tgz压缩包至linux上(在指定的自定义路径) 
或者直接在linux上：
wegt https://www.python.org/ftp/python/3.5.4/Python-3.5.4.tgz
②docker cp 自定义路径/Python-3.5.4.tgz 容器id：/home/
③tar -zxvf Python-3.5.4.tgz
④cd Python-3.5.4
⑤编译：./configure --prefix=/usr/local/python3
问题：Python3..4安装报错 configure: error: in `/usr/local/python3/Python-3.5.4'
configure: error: no acceptable C compiler found in $PATH
解决：缺少gcc编译环境：yum -y install gcc

⑥安装：make && make install

⑦建立软链接
ln -s /usr/local/python3/bin/python3.5 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.5 /usr/bin/pip3

⑧查看python3与pip3版本
python3
pip3 –V

问题：pip3 -V : pip3 command not found
解决：
wget --no-check-certificate https://pypi.python.org/packages/26/d1/dc7fe14ce4a3ff3faebf1ac11350de4104ea2d2a80c98393b55c84362b0c/setuptools-32.1.0.tar.gz
tar zxvf setuptools-32.1.0.tar.gz
cd setuptools-32.1.0
python3 setup.py build
python3 setup.py install

wget --no-check-certificate https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz
tar zxvf pip-9.0.1.tar.gz
cd pip-9.0.1
python3 setup.py install

问题：Compression requires the (missing) zlib module.
解决：yum install zlib 

⑨上传项目
docker cp /www/pro_tesu/TSDRM容器ID:/root/
从清华大小pip源安装依赖
cd TSDRM
pip3 install –r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple/

问题:安装依赖的时候，发现安装了之后运行项目python3 manage.py runserver 0.0.0.0:8000,还是会报错，模块没有安装成功
解决:报什么模块没有 执行:pip3 install 模块名==版本号 ，再运行项目，报错，依次执行
如项目一些重要的模块必须安装：pip3 install redis==版本号
　　　　　　　　　　　　　　　pip3 install celery==版本号
　　　　　　　　　　　　　　　pip3 install django-celery==版本号
　　　　　　　　　　　　　　　pip3 install flower==版本号

问题：No module named Cython
解决：pip install Cython
pip install fasttext

5.5 配置uwsgi

①cd TSDRM
②ls
③vi uwsgi.ini
④填写配置参数(见附录)
保存退出
⑥运行uwsgi: uwsgi --ini uwsgi.ini
⑦访问项目:192.168.1.89,执行正确会显示没有样式的页面
问题:在运行uwsgi时: uwsgi:command not found
解决：找到uwsgi的位置: find / -name uwsgi ——>>> /usr/local/python3/bin/uwsgi
建立软链接: ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi
输入uwsgi --help 查看是否成功

启动成功: [uwsgi-static] added mapping for /static => /home/personl_blog/static
关闭uwsgi: uwsgi --stop uwsgi.pid

5.6 安装pdf生成软件：wkhtmltopdf

在https://github.com/wkhtmltopdf/wkhtmltopdf/releases/ 下载对应的安装包，在这里我选择：wkhtmltox-0.12.5-1.centos6. x86_64.rpm

rpm -ivh wkhtmltox-0.12.5-1.centos6. x86_64.rpm

测试是否安装成功：
wkhtmltopdf http://www.baidu.com ./test.pdf    注：这里是把百度的首页转成test.pdf文件，保存在当前路径下

安装软件报错：

[root@7f8a11fc9311 home]# rpm -ivh wkhtmltox-0.12.5-1.centos6.x86_64.rpm
error: Failed dependencies:
        fontconfig is needed by wkhtmltox-1:0.12.5-1.centos6.x86_64

        xorg-x11-fonts-Type1 is needed by wkhtmltox-1:0.12.5-1.centos6.x86_64

解决:通过yum安装以上安装报错的模块
yum install -y fontconfig freetype libX11 libXext libXrender libjpeg libpng xorg-x11-fonts-75dpi xorg-x11-fonts-Type1

5.7 下载中文字体simsun.ttc

下载：http://www.font5.com.cn/font_download.php?id=150&part=1237886897
上传到 linux系统 /usr/share/fonts
docker cp /usr/share/fonts /simsun.ttc 容器ID:/usr/share/fonts

5.8 修改项目中数据库的地址

cd TSDRM
cd TSDRM
vi settings.py
mysql：
　　HOST:172.17.0.3    注：这个ip地址是mysql容器的ip
　　PORT:3306
redis：172.17.0.2      注：这个ip地址是redis容器的ip
　　　　6379

5.9 安装静态文件

1、collectstatic命令收集静态文件至项目根目录下：
python manage.py collectstatic

2、注释STATICFILES_DIRS ，解注：STATIC_ROOT
STATIC_URL = '/static/'
SITE_ROOT = os.path.join(os.path.abspath(os.path.dirname(__file__)), '..')
STATIC_ROOT = os.path.join(SITE_ROOT, 'static')

# STATICFILES_DIRS = [
#     os.path.join(BASE_DIR, "static")
# ]

5.10 浏览器访问：192.168.1.89

5.11 cmd访问192.168.1.89

六、打包自定义镜像上传阿里云

6.1 先关闭容器：docker stop 容器ID

6.2 基于当前容器重新创建镜像

docker commit -m "描述" -a "root" -p 容器id 镜像名称:版本号

如：docker commit -m "centos6.8_python3.4" -a "root" -p 容器id en_centos:2.2

-p 表示提交时停止容器
-a 提交镜像的作者
-m 提交时的说明文字

6.3 创建阿里云账号

https://cr.console.aliyun.com/cn-hangzhou/instances/repositories

6.4 登录阿里云账号

docker login --username=zgs1121 registry.cn-hangzhou.aliyuncs.com

password:**********

6.5 将镜像上传到阿里云的镜像仓库

docker tag 镜像ID registry.cn-hangzhou.aliyuncs.com/tesu/仓库名（en_centos）
docker push registry.cn-hangzhou.aliyuncs.com/tesu/仓库名（en_centos）

七、下拉自定义镜像并创建项目Django容器

7.1 拉取镜像

docker pull registry.cn-hangzhou.aliyuncs.com/tesunet/en_centos

7.2 命名镜像

docker tag registry.cn-hangzhou.aliyuncs.com/tesunet/en_centos 新镜像名称

八、django项目容器

8.1 切到项目所在的路径下

cd /www/pro_tesu/

8.2 基于自定义镜像创建容器

docker run -p 8000:8000 \
-v $PWD/TSDRM:/TSDRM \
--link tesudrm_mysql:mysql_server \
--link tesudrm_redis:redis_server \
--name tesudrm_tsdrm \
-itd centos_python\
sh -c 'cd /TSDRM/&&\
uwsgi --ini uwsgi.ini&&\
python3 manage.py celery multi start worker -A TSDRM -l info --logfile=/TSDRM/log/celerylog.log&&\
python3 manage.py celery multi start beat -A TSDRM -l info --logfile=/TSDRM/log/beat.log&&\
python3 manage.py celery -A TSDRM flower -l info'

注：sh -c ‘…’ 表示启动容器时运行的命令，命令结束容器并会自动断开，所以多个命令的最后一个必须在终端一直运行的命令，或者是无限循环。

8.3 进入容器

docker exec -it 容器id bin/bash

8.4 切换到项目路径下

cd TSDRM

8.5 启动uwsgi

uwsgi --ini uwsgi.ini

8.6 运行项目

python3 manage.py runserver 0.0.0.0:80
注：如有模块没有安装，安装模块

8.7 上述项目跑起来了，页面没有样式，需安装静态文件。如果你的自定义镜像中安装了静态文件等，就不需要执行此操作

①切换到项目根路径下: cd TSDRM
②收集静态文件: python3 manage.py collectstatic 注: 收集好的静态文件存放于项目根目录下,名为: static
③查看静态文件: cd static ls
④修改配置文件
注释: STATICFILES_DIRS = [os.path.join(BASE_DIR, "static")]
添加: STATIC_URL = '/static/'
SITE_ROOT = os.path.join(os.path.abspath(os.path.dirname(__file__)), '..')
STATIC_ROOT = os.path.join(SITE_ROOT, 'static')

8.9 访问项目:192.168.1.89

九、运行nginx容器

9.1 拉取镜像

docker pull nginx

9.2 运行容器

运行容器之前先配置好文件，配置文件见附录

cd /www/pro_tesu/

docker run -v $PWD/Nginx/nginx.conf:/etc/nginx/nginx.conf \
               -v $PWD/Nginx/log:/var/log/nginx \
               -v $PWD/TSDRM/static:/static \
               --link tesudrm_tsdrm:django_server \
               --name tesudrm_nginx \
               -d -p 8888:80 nginx

9.3 访问项目

192.168.1.89:8888

另附：启动nginx容器，浏览器访问nginx

9.4 电脑重启后启动容器命令

docker start tesudrm_mysql tesudrm_redis tesudrm_pro tesudrm_nginx

十、附录

10.1 uwsgi.ini配置文件

[uwsgi]
#socket=0.0.0.0:8000 配置nginx代理时使用
http=0.0.0.0:8000
chdir=/TSDRM
#module=TSDRM.wsgi:application
wsgi-file=/TSDRM/TSDRM/wsgi.py
master=True
process=4
pidfile=/TSDRM/TSDRM-master.pid
vacuum=True
max-requests=5000
#daemonize=/TSDRM/log/wsgi.log
#static-map=/static=/TSDRM/static   

10.2 Mysql配置文件

[mysql]
default-character-set=utf8
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character-set-server=utf8
default-storage-engine=INNODB
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

10.3 Redis配置文件

# Redis configuration file example.
#
# Note that in order to read the configuration file, Redis must be
# started with the file path as first argument:
#
# ./redis-server /path/to/redis.conf

# Note on units: when memory size is needed, it is possible to specify
# it in the usual form of 1k 5GB 4M and so forth:
#
# 1k => 1000 bytes
# 1kb => 1024 bytes
# 1m => 1000000 bytes
# 1mb => 1024*1024 bytes
# 1g => 1000000000 bytes
# 1gb => 1024*1024*1024 bytes
#
# units are case insensitive so 1GB 1Gb 1gB are all the same.

################################## INCLUDES ###################################

# Include one or more other config files here.  This is useful if you
# have a standard template that goes to all Redis servers but also need
# to customize a few per-server settings.  Include files can include
# other files, so use this wisely.
#
# Notice option "include" won't be rewritten by command "CONFIG REWRITE"
# from admin or Redis Sentinel. Since Redis always uses the last processed
# line as value of a configuration directive, you'd better put includes
# at the beginning of this file to avoid overwriting config change at runtime.
#
# If instead you are interested in using includes to override configuration
# options, it is better to use include as the last line.
#
# include /path/to/local.conf
# include /path/to/other.conf

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 lookback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# bind 127.0.0.1

# Protected mode is a layer of security protection, in order to avoid that
# Redis instances left open on the internet are accessed and exploited.
#
# When protected mode is on and if:
#
# 1) The server is not binding explicitly to a set of addresses using the
#    "bind" directive.
# 2) No password is configured.
#
# The server only accepts connections from clients connecting from the
# IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain

################################# REPLICATION #################################

# Master-Slave replication. Use slaveof to make a Redis instance a copy of
# another Redis server. A few things to understand ASAP about Redis replication.
#
# 1) Redis replication is asynchronous, but you can configure a master to
#    stop accepting writes if it appears to be not connected with at least
#    a given number of slaves.
# 2) Redis slaves are able to perform a partial resynchronization with the
#    master if the replication link is lost for a relatively small amount of
#    time. You may want to configure the replication backlog size (see the next
#    sections of this file) with a sensible value depending on your needs.
# 3) Replication is automatic and does not need user intervention. After a
#    network partition slaves automatically try to reconnect to masters
#    and resynchronize with them.
#
# slaveof <masterip> <masterport>

# If the master is password protected (using the "requirepass" configuration
# directive below) it is possible to tell the slave to authenticate before
# starting the replication synchronization process, otherwise the master will
# refuse the slave request.
#
# masterauth <master-password>

# When a slave loses its connection with the master, or when the replication
# is still in progress, the slave can act in two different ways:
#
# 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will
#    still reply to client requests, possibly with out of date data, or the
#    data set may just be empty if this is the first synchronization.
#
# 2) if slave-serve-stale-data is set to 'no' the slave will reply with
#    an error "SYNC with master in progress" to all the kind of commands
#    but to INFO and SLAVEOF.
#
slave-serve-stale-data yes

# You can configure a slave instance to accept writes or not. Writing against
# a slave instance may be useful to store some ephemeral data (because data
# written on a slave will be easily deleted after resync with the master) but
# may also cause problems if clients are writing to it because of a
# misconfiguration.
#
# Since Redis 2.6 by default slaves are read-only.
#
# Note: read only slaves are not designed to be exposed to untrusted clients
# on the internet. It's just a protection layer against misuse of the instance.
# Still a read only slave exports by default all the administrative commands
# such as CONFIG, DEBUG, and so forth. To a limited extent you can improve
# security of read only slaves using 'rename-command' to shadow all the
# administrative / dangerous commands.
slave-read-only yes

# Replication SYNC strategy: disk or socket.
#
# -------------------------------------------------------
# WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY
# -------------------------------------------------------
#
# New slaves and reconnecting slaves that are not able to continue the replication
# process just receiving differences, need to do what is called a "full
# synchronization". An RDB file is transmitted from the master to the slaves.
# The transmission can happen in two different ways:
#
# 1) Disk-backed: The Redis master creates a new process that writes the RDB
#                 file on disk. Later the file is transferred by the parent
#                 process to the slaves incrementally.
# 2) Diskless: The Redis master creates a new process that directly writes the
#              RDB file to slave sockets, without touching the disk at all.
#
# With disk-backed replication, while the RDB file is generated, more slaves
# can be queued and served with the RDB file as soon as the current child producing
# the RDB file finishes its work. With diskless replication instead once
# the transfer starts, new slaves arriving will be queued and a new transfer
# will start when the current one terminates.
#
# When diskless replication is used, the master waits a configurable amount of
# time (in seconds) before starting the transfer in the hope that multiple slaves
# will arrive and the transfer can be parallelized.
#
# With slow disks and fast (large bandwidth) networks, diskless replication
# works better.
repl-diskless-sync no

# When diskless replication is enabled, it is possible to configure the delay
# the server waits in order to spawn the child that transfers the RDB via socket
# to the slaves.
#
# This is important since once the transfer starts, it is not possible to serve
# new slaves arriving, that will be queued for the next RDB transfer, so the server
# waits a delay in order to let more slaves arrive.
#
# The delay is specified in seconds, and by default is 5 seconds. To disable
# it entirely just set it to 0 seconds and the transfer will start ASAP.
repl-diskless-sync-delay 5

# Slaves send PINGs to server in a predefined interval. It's possible to change
# this interval with the repl_ping_slave_period option. The default value is 10
# seconds.
#
# repl-ping-slave-period 10

# The following option sets the replication timeout for:
#
# 1) Bulk transfer I/O during SYNC, from the point of view of slave.
# 2) Master timeout from the point of view of slaves (data, pings).
# 3) Slave timeout from the point of view of masters (REPLCONF ACK pings).
#
# It is important to make sure that this value is greater than the value
# specified for repl-ping-slave-period otherwise a timeout will be detected
# every time there is low traffic between the master and the slave.
#
# repl-timeout 60

# Disable TCP_NODELAY on the slave socket after SYNC?
#
# If you select "yes" Redis will use a smaller number of TCP packets and
# less bandwidth to send data to slaves. But this can add a delay for
# the data to appear on the slave side, up to 40 milliseconds with
# Linux kernels using a default configuration.
#
# If you select "no" the delay for data to appear on the slave side will
# be reduced but more bandwidth will be used for replication.
#
# By default we optimize for low latency, but in very high traffic conditions
# or when the master and slaves are many hops away, turning this to "yes" may
# be a good idea.
repl-disable-tcp-nodelay no

# Set the replication backlog size. The backlog is a buffer that accumulates
# slave data when slaves are disconnected for some time, so that when a slave
# wants to reconnect again, often a full resync is not needed, but a partial
# resync is enough, just passing the portion of data the slave missed while
# disconnected.
#
# The bigger the replication backlog, the longer the time the slave can be
# disconnected and later be able to perform a partial resynchronization.
#
# The backlog is only allocated once there is at least a slave connected.
#
# repl-backlog-size 1mb

# After a master has no longer connected slaves for some time, the backlog
# will be freed. The following option configures the amount of seconds that
# need to elapse, starting from the time the last slave disconnected, for
# the backlog buffer to be freed.
#
# A value of 0 means to never release the backlog.
#
# repl-backlog-ttl 3600

# The slave priority is an integer number published by Redis in the INFO output.
# It is used by Redis Sentinel in order to select a slave to promote into a
# master if the master is no longer working correctly.
#
# A slave with a low priority number is considered better for promotion, so
# for instance if there are three slaves with priority 10, 100, 25 Sentinel will
# pick the one with priority 10, that is the lowest.
#
# However a special priority of 0 marks the slave as not able to perform the
# role of master, so a slave with priority of 0 will never be selected by
# Redis Sentinel for promotion.
#
# By default the priority is 100.
slave-priority 100

# It is possible for a master to stop accepting writes if there are less than
# N slaves connected, having a lag less or equal than M seconds.
#
# The N slaves need to be in "online" state.
#
# The lag in seconds, that must be <= the specified value, is calculated from
# the last ping received from the slave, that is usually sent every second.
#
# This option does not GUARANTEE that N replicas will accept the write, but
# will limit the window of exposure for lost writes in case not enough slaves
# are available, to the specified number of seconds.
#
# For example to require at least 3 slaves with a lag <= 10 seconds use:
#
# min-slaves-to-write 3
# min-slaves-max-lag 10
#
# Setting one or the other to 0 disables the feature.
#
# By default min-slaves-to-write is set to 0 (feature disabled) and
# min-slaves-max-lag is set to 10.

# A Redis master is able to list the address and port of the attached
# slaves in different ways. For example the "INFO replication" section
# offers this information, which is used, among other tools, by
# Redis Sentinel in order to discover slave instances.
# Another place where this info is available is in the output of the
# "ROLE" command of a masteer.
#
# The listed IP and address normally reported by a slave is obtained
# in the following way:
#
#   IP: The address is auto detected by checking the peer address
#   of the socket used by the slave to connect with the master.
#
#   Port: The port is communicated by the slave during the replication
#   handshake, and is normally the port that the slave is using to
#   list for connections.
#
# However when port forwarding or Network Address Translation (NAT) is
# used, the slave may be actually reachable via different IP and port
# pairs. The following two options can be used by a slave in order to
# report to its master a specific set of IP and port, so that both INFO
# and ROLE will report those values.
#
# There is no need to use both the options if you need to override just
# the port or the IP address.

# Command renaming.
#
# It is possible to change the name of dangerous commands in a shared

# but not available for general clients.
#
# Example:
#
# rename-command CONFIG b840fc02d524045429941cc15f59e41cb7be6c52
#
# It is also possible to completely kill a command by renaming it into
# an empty string:
#
# rename-command CONFIG ""
#
# Please note that changing the name of commands that are logged into the
# AOF file or transmitted to slaves may cause problems.

################################### LIMITS ####################################

# Set the max number of connected clients at the same time. By default
# this limit is set to 10000 clients, however if the Redis server is not
# able to configure the process file limit to allow for the specified limit
# the max number of allowed clients is set to the current file limit
# minus 32 (as Redis reserves a few file descriptors for internal uses).
#
# Once the limit is reached Redis will close all the new connections sending
# an error 'max number of clients reached'.
#
# maxclients 10000

# Don't use more memory than the specified amount of bytes.
# When the memory limit is reached Redis will try to remove keys
# according to the eviction policy selected (see maxmemory-policy).
#
# If Redis can't remove keys according to the policy, or if the policy is
# set to 'noeviction', Redis will start to reply with errors to commands
# that would use more memory, like SET, LPUSH, and so on, and will continue
# to reply to read-only commands like GET.
#
# This option is usually useful when using Redis as an LRU cache, or to set
# a hard memory limit for an instance (using the 'noeviction' policy).
#
# WARNING: If you have slaves attached to an instance with maxmemory on,
# the size of the output buffers needed to feed the slaves are subtracted
# from the used memory count, so that network problems / resyncs will
# not trigger a loop where keys are evicted, and in turn the output
# buffer of slaves is full with DELs of keys evicted triggering the deletion
# of more keys, and so forth until the database is completely emptied.
#
# In short... if you have slaves attached it is suggested that you set a lower
# limit for maxmemory so that there is some free RAM on the system for slave
# output buffers (but this is not needed if the policy is 'noeviction').
#
# maxmemory <bytes>

# MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
# is reached. You can select among five behaviors:
#
# volatile-lru -> remove the key with an expire set using an LRU algorithm
# allkeys-lru -> remove any key according to the LRU algorithm
# volatile-random -> remove a random key with an expire set
# allkeys-random -> remove a random key, any key
# volatile-ttl -> remove the key with the nearest expire time (minor TTL)
# noeviction -> don't expire at all, just return an error on write operations
#
# Note: with any of the above policies, Redis will return an error on write
#       operations, when there are no suitable keys for eviction.
#
#       At the date of writing these commands are: set setnx setex append
#       incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
#       sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby
#       zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby
#       getset mset msetnx exec sort
#
# The default is:
#
# maxmemory-policy noeviction

# LRU and minimal TTL algorithms are not precise algorithms but approximated
# algorithms (in order to save memory), so you can tune it for speed or
# accuracy. For default Redis will check five keys and pick the one that was
# used less recently, you can change the sample size using the following
# configuration directive.
#
# The default of 5 produces good enough results. 10 Approximates very closely
# true LRU but costs a bit more CPU. 3 is very fast but not very accurate.
#
# maxmemory-samples 5

############################## APPEND ONLY MODE ###############################

# By default Redis asynchronously dumps the dataset on disk. This mode is
# good enough in many applications, but an issue with the Redis process or
# a power outage may result into a few minutes of writes lost (depending on
# the configured save points).
#
# The Append Only File is an alternative persistence mode that provides
# much better durability. For instance using the default data fsync policy
# (see later in the config file) Redis can lose just one second of writes in a
# dramatic event like a server power outage, or a single write if something
# wrong with the Redis process itself happens, but the operating system is
# still running correctly.
#
# AOF and RDB persistence can be enabled at the same time without problems.
# If the AOF is enabled on startup Redis will load the AOF, that is the file
# with the better durability guarantees.
#
# Please check http://redis.io/topics/persistence for more information.

appendonly no

# The name of the append only file (default: "appendonly.aof")

appendfilename "appendonly.aof"

# The fsync() call tells the Operating System to actually write data on disk
# instead of waiting for more data in the output buffer. Some OS will really flush
# data on disk, some other OS will just try to do it ASAP.
#
# Redis supports three different modes:
#
# no: don't fsync, just let the OS flush the data when it wants. Faster.
# always: fsync after every write to the append only log. Slow, Safest.
# everysec: fsync only one time every second. Compromise.
#
# The default is "everysec", as that's usually the right compromise between
# speed and data safety. It's up to you to understand if you can relax this to
# "no" that will let the operating system flush the output buffer when
# it wants, for better performances (but if you can live with the idea of
# some data loss consider the default persistence mode that's snapshotting),
# or on the contrary, use "always" that's very slow but a bit safer than
# everysec.
#
# More details please check the following article:
# http://antirez.com/post/redis-persistence-demystified.html
#
# If unsure, use "everysec".

# appendfsync always
appendfsync everysec
# appendfsync no

# When the AOF fsync policy is set to always or everysec, and a background
# saving process (a background save or AOF log background rewriting) is
# performing a lot of I/O against the disk, in some Linux configurations
# Redis may block too long on the fsync() call. Note that there is no fix for
# this currently, as even performing fsync in a different thread will block
# our synchronous write(2) call.
#
# In order to mitigate this problem it's possible to use the following option
# that will prevent fsync() from being called in the main process while a
# BGSAVE or BGREWRITEAOF is in progress.
#
# This means that while another child is saving, the durability of Redis is
# the same as "appendfsync none". In practical terms, this means that it is
# possible to lose up to 30 seconds of log in the worst scenario (with the
# default Linux settings).
#
# If you have latency problems turn this to "yes". Otherwise leave it as
# "no" that is the safest pick from the point of view of durability.

no-appendfsync-on-rewrite no

# Automatic rewrite of the append only file.
# Redis is able to automatically rewrite the log file implicitly calling
# BGREWRITEAOF when the AOF log size grows by the specified percentage.
#
# This is how it works: Redis remembers the size of the AOF file after the
# latest rewrite (if no rewrite has happened since the restart, the size of
# the AOF at startup is used).
#
# This base size is compared to the current size. If the current size is
# bigger than the specified percentage, the rewrite is triggered. Also
# you need to specify a minimal size for the AOF file to be rewritten, this
# is useful to avoid rewriting the AOF file even if the percentage increase
# is reached but it is still pretty small.
#
# Specify a percentage of zero in order to disable the automatic AOF
# rewrite feature.

auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb

# An AOF file may be found to be truncated at the end during the Redis
# startup process, when the AOF data gets loaded back into memory.
# This may happen when the system where Redis is running
# crashes, especially when an ext4 filesystem is mounted without the
# data=ordered option (however this can't happen when Redis itself
# crashes or aborts but the operating system still works correctly).
#
# Redis can either exit with an error when this happens, or load as much
# data as possible (the default now) and start if the AOF file is found
# to be truncated at the end. The following option controls this behavior.
#
# If aof-load-truncated is set to yes, a truncated AOF file is loaded and
# the Redis server starts emitting a log to inform the user of the event.
# Otherwise if the option is set to no, the server aborts with an error
# and refuses to start. When the option is set to no, the user requires
# to fix the AOF file using the "redis-check-aof" utility before to restart
# the server.
#
# Note that if the AOF file will be found to be corrupted in the middle
# the server will still exit with an error. This option only applies when
# Redis will try to read more data from the AOF file but not enough bytes
# will be found.

#
# cluster-enabled yes

# Every cluster node has a cluster configuration file. This file is not

# A slave of a failing master will avoid to start a failover if its data
# looks too old.
#
# There is no simple way for a slave to actually have a exact measure of
# its "data age", so the following two checks are performed:
#
# 1) If there are multiple slaves able to failover, they exchange messages
#    in order to try to give an advantage to the slave with the best
#    replication offset (more data from the master processed).
#    Slaves will try to get their rank by offset, and apply to the start
#    of the failover a delay proportional to their rank.
#
# 2) Every single slave computes the time of the last interaction with
#    its master. This can be the last ping or command received (if the master
#    is still in the "connected" state), or the time that elapsed since the
#    disconnection with the master (if the replication link is currently down).
#    If the last interaction is too old, the slave will not try to failover
#    at all.
#
# The point "2" can be tuned by user. Specifically a slave will not perform
# the failover if, since the last interaction with the master, the time
# elapsed is greater than:
#
#   (node-timeout * slave-validity-factor) + repl-ping-slave-period
#
# So for example if node-timeout is 30 seconds, and the slave-validity-factor
# is 10, and assuming a default repl-ping-slave-period of 10 seconds, the
# slave will not try to failover if it was not able to talk with the master
# for longer than 310 seconds.
#
# A large slave-validity-factor may allow slaves with too old data to failover
# a master, while a too small value may prevent the cluster from being able to
# elect a slave at all.
#
# For maximum availability, it is possible to set the slave-validity-factor
# to a value of 0, which means, that slaves will always try to failover the
# master regardless of the last time they interacted with the master.
# (However they'll always try to apply a delay proportional to their
# offset rank).
#
# Zero is the only value able to guarantee that when all the partitions heal
# the cluster will always be able to continue.
#
# cluster-slave-validity-factor 10

# Cluster slaves are able to migrate to orphaned masters, that are masters
# that are left without working slaves. This improves the cluster ability
# to resist to failures as otherwise an orphaned master can't be failed over
# in case of failure if it has no working slaves.
#
# Slaves migrate to orphaned masters only if there are still at least a
# given number of other working slaves for their old master. This number
# is the "migration barrier". A migration barrier of 1 means that a slave
# will migrate only if there is at least 1 other working slave for its master
# and so forth. It usually reflects the number of slaves you want for every
# master in your cluster.
#
# Default is 1 (slaves migrate only if their masters remain with at least
# one slave). To disable migration just set it to a very large value.
# A value of 0 can be set but is useful only for debugging and dangerous
# in production.
#

# By default Redis Cluster nodes stop accepting queries if they detect there
# is at least an hash slot uncovered (no available node is serving it).
# This way if the cluster is partially down (for example a range of hash slots
# are no longer covered) all the cluster becomes, eventually, unavailable.
# It automatically returns available as soon as all the slots are covered again.
#
# However sometimes you want the subset of the cluster which is working,
# to continue to accept queries for the part of the key space that is still
# covered. In order to do so, just set the cluster-require-full-coverage
# option to no.
#
# cluster-require-full-coverage yes

# In order to setup your cluster make sure to read the documentation
# available at http://redis.io web site.

################################## SLOW LOG ###################################

# The Redis Slow Log is a system to log queries that exceeded a specified
# execution time. The execution time does not include the I/O operations
# like talking with the client, sending the reply and so forth,
# but just the time needed to actually execute the command (this is the only
# stage of command execution where the thread is blocked and can not serve
# other requests in the meantime).
#
# You can configure the slow log with two parameters: one tells Redis
# what is the execution time, in microseconds, to exceed in order for the
# command to get logged, and the other parameter is the length of the
# slow log. When a new command is logged the oldest one is removed from the
# queue of logged commands.

# The following time is expressed in microseconds, so 1000000 is equivalent
# to one second. Note that a negative number disables the slow log, while
# a value of zero forces the logging of every command.
slowlog-log-slower-than 10000

# There is no limit to this length. Just be aware that it will consume memory.
# You can reclaim memory used by the slow log with SLOWLOG RESET.

################################ LATENCY MONITOR ##############################

# The Redis latency monitoring subsystem samples different operations
# at runtime in order to collect data related to possible sources of
# latency of a Redis instance.
#
# Via the LATENCY command this information is available to the user that can
# print graphs and obtain reports.
#
# The system only logs operations that were performed in a time equal or
# greater than the amount of milliseconds specified via the
# latency-monitor-threshold configuration directive. When its value is set
# to zero, the latency monitor is turned off.
#
# By default latency monitoring is disabled since it is mostly not needed
# if you don't have latency issues, and collecting data has a performance
# impact, that while very small, can be measured under big load. Latency
# monitoring can easily be enabled at runtime using the command
# "CONFIG SET latency-monitor-threshold <milliseconds>" if needed.
latency-monitor-threshold 0

############################# EVENT NOTIFICATION ##############################

# Redis can notify Pub/Sub clients about events happening in the key space.
# This feature is documented at http://redis.io/topics/notifications
#
# For instance if keyspace events notification is enabled, and a client
# performs a DEL operation on key "foo" stored in the Database 0, two
# messages will be published via Pub/Sub:
#
# PUBLISH __keyspace@0__:foo del
# PUBLISH __keyevent@0__:del foo
#
# It is possible to select the events that Redis will notify among a set
# of classes. Every class is identified by a single character:
#
#  K     Keyspace events, published with __keyspace@<db>__ prefix.
#  E     Keyevent events, published with __keyevent@<db>__ prefix.
#  g     Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
#  $     String commands
#  l     List commands
#  s     Set commands
#  h     Hash commands
#  z     Sorted set commands
#  x     Expired events (events generated every time a key expires)
#  e     Evicted events (events generated when a key is evicted for maxmemory)
#  A     Alias for g$lshzxe, so that the "AKE" string means all the events.
#
#  The "notify-keyspace-events" takes as argument a string that is composed
#  of zero or multiple characters. The empty string means that notifications
#  are disabled.
#
#  Example: to enable list and generic events, from the point of view of the
#           event name, use:
#
#  notify-keyspace-events Elg
#
#  Example 2: to get the stream of the expired keys subscribing to channel
#             name __keyevent@0__:expired use:
#
#  notify-keyspace-events Ex
#
#  By default all notifications are disabled because most users don't need
#  this feature and the feature has some overhead. Note that if you don't
#  specify at least one of K or E, no events will be delivered.

############################### ADVANCED CONFIG ###############################

# Hashes are encoded using a memory efficient data structure when they have a
# small number of entries, and the biggest entry does not exceed a given
# threshold. These thresholds can be configured using the following directives.
hash-max-ziplist-entries 512
hash-max-ziplist-value 64

# Lists are also encoded in a special way to save a lot of space.
# The number of entries allowed per internal list node can be specified
# as a fixed maximum size or a maximum number of elements.
# For a fixed maximum size, use -5 through -1, meaning:
# -5: max size: 64 Kb  <-- not recommended for normal workloads
# -4: max size: 32 Kb  <-- not recommended
# -3: max size: 16 Kb  <-- probably not recommended
# -2: max size: 8 Kb   <-- good
# -1: max size: 4 Kb   <-- good
# Positive numbers mean store up to _exactly_ that number of elements
# per list node.
# The highest performing option is usually -2 (8 Kb size) or -1 (4 Kb size),
# but if your use case is unique, adjust the settings as necessary.
list-max-ziplist-size -2

# Lists may also be compressed.
# Compress depth is the number of quicklist ziplist nodes from *each* side of
# the list to *exclude* from compression.  The head and tail of the list
# are always uncompressed for fast push/pop operations.  Settings are:
# 0: disable all list compression
# 1: depth 1 means "don't start compressing until after 1 node into the list,
#    going from either the head or tail"
#    So: [head]->node->node->...->node->[tail]
#    [head], [tail] will always be uncompressed; inner nodes will compress.
# 2: [head]->[next]->node->node->...->node->[prev]->[tail]
#    2 here means: don't compress head or head->next or tail->prev or tail,
#    but compress all nodes between them.
# 3: [head]->[next]->[next]->node->node->...->node->[prev]->[prev]->[tail]
# etc.

# Sets have a special encoding in just one case: when a set is composed
# of just strings that happen to be integers in radix 10 in the range
# of 64 bit signed integers.
# The following configuration setting sets the limit in the size of the
# set in order to use this special memory saving encoding.
set-max-intset-entries 512

# Similarly to hashes and lists, sorted sets are also specially encoded in
# order to save a lot of space. This encoding is only used when the length and
# elements of a sorted set are below the following limits:
zset-max-ziplist-entries 128
zset-max-ziplist-value 64

# HyperLogLog sparse representation bytes limit. The limit includes the
# 16 bytes header. When an HyperLogLog using the sparse representation crosses
# this limit, it is converted into the dense representation.
#
# A value greater than 16000 is totally useless, since at that point the
# dense representation is more memory efficient.
#
# The suggested value is ~ 3000 in order to have the benefits of
# the space efficient encoding without slowing down too much PFADD,
# which is O(N) with the sparse encoding. The value can be raised to
# ~ 10000 when CPU is not a concern, but space is, and the data set is
# composed of many HyperLogLogs with cardinality in the 0 - 15000 range.

# Active rehashing uses 1 millisecond every 100 milliseconds of CPU time in
# order to help rehashing the main Redis hash table (the one mapping top-level
# keys to values). The hash table implementation Redis uses (see dict.c)
# performs a lazy rehashing: the more operation you run into a hash table
# that is rehashing, the more rehashing "steps" are performed, so if the
# server is idle the rehashing is never complete and some more memory is used
# by the hash table.
#
# The default is to use this millisecond 10 times every second in order to
# actively rehash the main dictionaries, freeing memory when possible.
#
# If unsure:
# use "activerehashing no" if you have hard latency requirements and it is
# not a good thing in your environment that Redis can reply from time to time
# to queries with 2 milliseconds delay.
#
# use "activerehashing yes" if you don't have such hard requirements but
# want to free memory asap when possible.

# The client output buffer limits can be used to force disconnection of clients
# that are not reading data from the server fast enough for some reason (a
# common reason is that a Pub/Sub client can't consume messages as fast as the
# publisher can produce them).
#
# The limit can be set differently for the three different classes of clients:
#
# normal -> normal clients including MONITOR clients
# slave  -> slave clients
# pubsub -> clients subscribed to at least one pubsub channel or pattern
#
# The syntax of every client-output-buffer-limit directive is the following:
#
# client-output-buffer-limit <class> <hard limit> <soft limit> <soft seconds>
#
# A client is immediately disconnected once the hard limit is reached, or if
# the soft limit is reached and remains reached for the specified number of
# seconds (continuously).
# So for instance if the hard limit is 32 megabytes and the soft limit is
# 16 megabytes / 10 seconds, the client will get disconnected immediately
# if the size of the output buffers reach 32 megabytes, but will also get
# disconnected if the client reaches 16 megabytes and continuously overcomes
# the limit for 10 seconds.
#
# By default normal clients are not limited because they don't receive data
# without asking (in a push way), but just after a request, so only
# asynchronous clients may create a scenario where data is requested faster
# than it can read.
#
# Instead there is a default limit for pubsub and slave clients, since
# subscribers and slaves receive data in a push fashion.
#
# Both the hard or the soft limit can be disabled by setting them to zero.
client-output-buffer-limit normal 0 0 0

client-output-buffer-limit pubsub 32mb 8mb 60

# Redis calls an internal function to perform many background tasks, like
# closing connections of clients in timeout, purging expired keys that are
# never requested, and so forth.
#
# Not all tasks are performed with the same frequency, but Redis checks for
# tasks to perform according to the specified "hz" value.
#
# By default "hz" is set to 10. Raising the value will use more CPU when
# Redis is idle, but at the same time will make Redis more responsive when
# there are many keys expiring at the same time, and timeouts may be
# handled with more precision.
#
# The range is between 1 and 500, however a value over 100 is usually not
# a good idea. Most users should use the default of 10 and raise this up to
# 100 only in environments where very low latency is required.

# When a child rewrites the AOF file, if the following option is enabled
