部署redis5.0.3

一、准备环境

1、下载

# wget http://download.redis.io/releases/redis-5.0.3.tar.gz

[root@localhost ~]# wget http://download.redis.io/releases/redis-5.0.3.tar.gz

[root@localhost ~]# ls
redis-5.0..tar.gz 

2、解压

[root@localhost ~]# tar xzf redis-5.0..tar.gz
[root@localhost ~]#
[root@localhost ~]# ls
anaconda-ks.cfg  redis-5.0.  redis-5.0..tar.gz
[root@localhost ~]#
[root@localhost ~]# cd redis-5.0.
[root@localhost redis-5.0.]#
[root@localhost redis-5.0.]# ls
-RELEASENOTES  CONTRIBUTING  deps     Makefile   README.md   runtest          runtest-sentinel  src    utils
BUGS             COPYING       INSTALL  MANIFESTO  redis.conf  runtest-cluster  sentinel.conf     tests

3、yum安装gcc依赖

# yum install gcc -y

4、编译

# make

[root@localhost redis-5.0.]# make
……………………
……………………
Hint: It's a good idea to run 'make test' ;)

make[]: Leaving directory `/root/redis-5.0./src'

5、简单启动

进入到解压后的 src 目录，通过如下命令启动Redis:

# ./redis-server

[root@localhost redis-5.0.]# ls
-RELEASENOTES  CONTRIBUTING  deps     Makefile   README.md   runtest          runtest-sentinel  src    utils
BUGS             COPYING       INSTALL  MANIFESTO  redis.conf  runtest-cluster  sentinel.conf     tests
[root@localhost redis-5.0.]#
[root@localhost redis-5.0.]# cd src/
[root@localhost src]#
[root@localhost src]# ./redis-server

:M  Mar  ::12.151 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

Redis must be restarted after THP is disabled.
:M  Mar  ::12.152 * Ready to accept connections

新打开一个窗口页进行简单的交互

可以使用内置的客户端与Redis进行交互:

# ./redis-cli

[root@localhost src]# ./redis-cli
127.0.0.1:> set foo bar
OK
127.0.0.1:> get foo
"bar"
127.0.0.1:>

二、正常安装

以下两个选项任选其一进行 (推荐选择默认安装)

• 安装命令 (默认安装目录是/usr/local/bin/)

# make install

[root@localhost redis-5.0.]# make install
cd src && make install
make[]: Entering directory `/root/redis-5.0./src'
    CC Makefile.dep
make[]: Leaving directory `/root/redis-5.0./src'
make[]: Entering directory `/root/redis-5.0./src'

Hint: It's a good idea to run 'make test' ;)

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[]: Leaving directory `/root/redis-5.0./src'
[root@localhost redis-5.0.]#

查看安装目录

# ll /usr/local/bin/redis-*

[root@localhost redis-5.0.]# ll /usr/local/bin/redis-*
-rwxr-xr-x.  root root  Mar  : /usr/local/bin/redis-benchmark
-rwxr-xr-x.  root root  Mar  : /usr/local/bin/redis-check-aof
-rwxr-xr-x.  root root  Mar  : /usr/local/bin/redis-check-rdb
-rwxr-xr-x.  root root  Mar  : /usr/local/bin/redis-cli
lrwxrwxrwx.  root root       Mar  : /usr/local/bin/redis-sentinel -> redis-server
-rwxr-xr-x.  root root  Mar  : /usr/local/bin/redis-server
[root@localhost redis-5.0.]#

• 指定redis安装目录

# make install PREFIX=/usr/local/redis

配置文件

配置文件在redis-5.0.3目录下,文件名是 redis.conf

根据你的安装目录,将配置文件拷贝至对应的目录,比如拷贝到 /root/目录下,命令如下:

[root@localhost redis-5.0.]# ls
-RELEASENOTES  CONTRIBUTING  deps     Makefile   README.md   runtest          runtest-sentinel  src    utils
BUGS             COPYING       INSTALL  MANIFESTO  redis.conf  runtest-cluster  sentinel.conf     tests
[root@localhost redis-5.0.]#
[root@localhost redis-5.0.]# cp redis.conf /root/
[root@localhost redis-5.0.]#
[root@localhost redis-5.0.]# cd
[root@localhost ~]#
[root@localhost ~]# ls
anaconda-ks.cfg  redis-5.0.  redis-5.0..tar.gz  redis.conf
[root@localhost ~]#

三、正常启动

启动redis命令和效果如下,默认是前台启动,按 ctrl+c 停止

# redis-server /root/redis-5.0.3/redis.conf

[root@localhost ~]# redis-server /root/redis-5.0./redis.conf
:C  Mar  ::14.612 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
:C  Mar  ::14.612 # Redis version=5.0., bits=, commit=, modified=, pid=, just started
:C  Mar  ::14.612 # Configuration loaded
:M  Mar  ::14.614 * Increased maximum number of open files to  (it was originally set to ).

      _.-``    `.  `_.  ''-._           Redis 5.0. (/)  bit
  .-`` .-```.  ```\/    _.,_ ''-._

 |`-._`-._    `-.__.-'    _.-'_.-'|
 |    `-._`-._        _.-'_.-'    |           http://redis.io
  `-._    `-._`-.__.-'_.-'    _.-'
 |`-._`-._    `-.__.-'    _.-'_.-'|
 |    `-._`-._        _.-'_.-'    |
  `-._    `-._`-.__.-'_.-'    _.-'
      `-._    `-.__.-'    _.-'
          `-._        _.-'
              `-.__.-'

:M  Mar  ::14.617 # WARNING: The TCP backlog setting of  cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of .
:M  Mar  ::14.617 # Server initialized
:M  Mar  ::14.617 # WARNING overcommit_memory is set to ! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
:M  Mar  ::14.617 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

Redis must be restarted after THP is disabled.
:M  Mar  ::14.617 * Ready to accept connections

后台启动

后台启动需要修改配置文件 (大概在136行 ),将daemonize no 改为 daemonize yes

重启启动,效果如下

# redis-server /root/redis-5.0.3/redis.conf

[root@localhost ~]# redis-server /root/redis-5.0./redis.conf
:C  Mar  ::35.264 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
:C  Mar  ::35.264 # Redis version=5.0., bits=, commit=, modified=, pid=, just started
:C  Mar  ::35.264 # Configuration loaded

查看redis服务进程

# ps aux | grep redis

[root@localhost ~]# ps aux | grep redis
root         0.2  0.4    ?        Ssl  :   : redis-server 127.0.0.1:
root         0.0  0.0     pts/    S+   :   : grep --color=auto redis
[root@localhost ~]#

本地客户端交互

[root@localhost ~]# redis-cli
127.0.0.1:> keys *
(empty list or set)
127.0.0.1:> set foo bar
OK
127.0.0.1:> get foo
"bar"
127.0.0.1:> exit
[root@localhost ~]#

远程客户端连接

直接使用客户端加参数 redis-cli -h <ip> 进行远程连接

[root@localhost ~]# redis-cli -h 192.168.2.88
Could not connect to Redis at 192.168.2.88:: Connection refused

默认配置会报错,连接被拒绝,需要修改配置文件 redis.conf

默认配置,69行默认绑定了本机地址,注释此配置或修改为自己的IP

# vi redis-5.0.3/redis.conf

redis-5.0.3 默认开启保护模式,protected-mode yes,修改为 protected-mode no

重新启动

# redis-server /root/redis-5.0.3/redis.conf

[root@localhost ~]# redis-server /root/redis-5.0./redis.conf
:C  Mar  ::06.700 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
:C  Mar  ::06.700 # Redis version=5.0., bits=, commit=, modified=, pid=, just started
:C  Mar  ::06.700 # Configuration loaded
[root@localhost ~]#

关闭redis服务

[root@localhost ~]# redis-cli shutdown
[root@localhost ~]#
[root@localhost ~]# ps aux | grep redis
root         0.0  0.0     pts/    S+   :   : grep --color=auto redis
[root@localhost ~]#

四、Redis配置文件详解

主要用到的配置文件如下：

#设置节点的IP
bind 127.0.0.1 192.168.2.211

#redis-5.0.3 默认开启保护模式,protected-mode yes,修改为 protected-mode no
protected-mode no

#redis端口号
port 

#redis后台运行
#设置后台启动
daemonize yes

#设置连接节点的密码
requirepass 

#aof模式持久化文件的名字（appendonly默认是no，yes就是打开aof持久化）
appendfilename "appendonly.aof"

#打开aof持久化
appendonly yes

#pidfile文件对应redis_6379.pid
pidfile /var/run/redis_6379.pid
