redis的管理工具

• phpredisadmin工具
• rdbtools管理工具
• saltstack管理redis
• 通过codis完成redis管理

一：phpredisadmin工具：类似于mysqladmin管理mysql一样

安装环境：

[root@node5 ~]# yum install httpd php php-redis -y

下载管理包：

[root@node5 html]# git clone https://github.com/erikdubbelboer/phpRedisAdmin.git

更改名称并解决依赖：

[root@node5 html]# mv phpRedisAdmin admin
[root@node5 html]# cd admin
[root@node5 admin]# git clone https://github.com/nrk/predis.git vendor #解决依赖包

启动http,启动前确认80端口没有被占用，如果被占用可以修改监听的默认端口为80以为的其他端口：

[root@node5 html]# /etc/init.d/httpd  restart
Stopping httpd:                                            [FAILED]
Starting httpd:                                            [  OK  ]
[root@node5 html]# chkconfig  httpd on

访问http://ServerIP/admin：

报错，无法打开，查看apache错误日志如下：

[Mon Mar 21 21:24:47 2016] [error] [client 192.168.10.1] PHP Fatal error:  require(): Failed opening required '/var/www/html/admin/includes/../vendor/autoload.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/admin/includes/common.inc.php on line 2

解决过程：

[root@node5 admin]# cd includes/
[root@node5 includes]# ls config.sample.inc.php  config.inc.php
[root@node5 includes]# vim config.inc.php
$config = array(
  'servers' => array(
    array(
      'name'   => 'local server', // Optional name.
      'host'   => '192.168.10.205', #配置为自己的主机IP
      'port'   => 6379,
      'filter' => '*',

      // Optional Redis authentication.
      //'auth' => 'redispasswordhere' // Warning: The password is sent in plain-text to the Redis server.
    ),  

保存退出后重新启动httpd：

[root@node5 includes]# /etc/init.d/httpd restart
   Stopping httpd: [ OK ]
   Starting httpd: [ OK ]

再次测试还是不能访问，报错如下：

[Mon Mar 21 21:55:27 2016] [error] [client 192.168.10.1] PHP Fatal error:  Call to undefined function mb_internal_encoding() in /var/www/html/admin/includes/common.inc.php on line 59

解决办法：

[root@node5 admin]# vim /var/www/html/admin/includes/common.inc.php
mb_internal_encoding('utf-8');
将此行改为注释，如下：
#mb_internal_encoding('utf-8'); 

访问：

配置管理多个reids Server：

[root@node5 includes]# pwd
/var/www/html/admin/includes
[root@node5 includes]# vim config.inc.php

$config = array(
  'servers' => array(
    array(
      'name'   => '182.168.10.205', // Optional name.
      'host'   => '192.168.10.205',
      'port'   => 6379,
      'filter' => '*',

      // Optional Redis authentication.
      //'auth' => 'redispasswordhere' // Warning: The password is sent in plain-text to the Redis server.
    ),  

    array(  #一个主机一个配置，名称自定义，IP和端口是Redis的IP和端口
      'name'   => '', // Optional name.name支持中文
      'host'   => '192.168.10.205',
      'port'   => 7001,
    ),  

    array(
      'name'   => '', // Optional name.
      'host'   => '192.168.10.205',
      'port'   => 7002,
    ),  

    array(
      'name'   => '', // Optional name.
      'host'   => '192.168.10.205',
      'port'   => 7003,
    ),  

更改完成以后无需重启apache，如果浏览器已经打开管理地址，刷新一下即可：

二：rdbtools管理工具：

使用pip命令安装,如果没有pip命令则先安装pip：

[root@node5 ~]# yum install python-pip

使用pip安装rdbtools： pip install rdbtools

[root@node5 ~]# pip install rdbtools
/usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning
You are using pip version 7.1.0, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting rdbtools

导出rdb中的key信息：

[root@node5 7001]# rdb -c memory dump_7001.rdb  >  memory.csv #然后将memory.csv文件下载到本地，即可用excel打开分析了，格式如下图：

三：通过saltstack管理redis：

模块名称：redismod

官方文档地址：https://docs.saltstack.com/en/latest/ref/modules/all/index.html

四：通过codis完成redis管理：

1.codis简介：

　　Codis 是一个分布式 Redis 解决方案, 对于上层的应用来说, 连接到 Codis Proxy 和连接原生的 Redis Server 没有明显的区别 (不支持的命令列表), 上层应用可以像使用单机的 Redis 一样使用, Codis 底层会处理请求的转发, 不停机的数据迁移等工作, 所有后边的一切事情, 对于前面的客户端来说是透明的, 可以简单的认为后边连接的是一个内存无限大的 Redis 服务.其架构如下：

Codis 由四部分组成:

• Codis Proxy (codis-proxy) #负责对redis server 的代理，可以在前端使用haproxy做负载均衡，负责调度redis-client的请求。
• Codis Dashboard (codis-config) #codis的管理工具，可以添加删除redis节点，发起数据迁移，还自带一个http server，提供一个dashboard可以在浏览器进行观察和配置。
• Codis Redis (codis-server) #基于redis 2.8做了一个分支，只能运行codis-server
• ZooKeeper/Etcd #Codis 依赖 ZooKeeper 来存放数据路由表和 codis-proxy 节点的元信息, codis-config 发起的命令都会通过 ZooKeeper 同步到各个存活的 codis-proxy.

codis-proxy 是客户端连接的 Redis 代理服务, codis-proxy 本身实现了 Redis 协议, 表现得和一个原生的 Redis 没什么区别 (就像 Twemproxy), 对于一个业务来说, 可以部署多个 codis-proxy, codis-proxy 本身是无状态的.

codis-config 是 Codis 的管理工具, 支持包括, 添加/删除 Redis 节点, 添加/删除 Proxy 节点, 发起数据迁移等操作. codis-config 本身还自带了一个 http server, 会启动一个 dashboard, 用户可以直接在浏览器上观察 Codis 集群的运行状态.

2.准备基础环境：

安装go语言并设置环境变量：

[root@node5 opt]# yum install golang -y #codis是基于go语言编写的，因此要安装go语言环境
[root@node5 opt]# mkdir /opt/gopath #保存go环境的路径
[root@node5 opt]# vim /etc/profile
    export GOPATH=/opt/gopath
[root@node5 opt]# source  /etc/profile

安装配置zookeeper，需要有java环境:

[root@node5 ~]# wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
[root@node5 ~]# mv zookeeper-3.4.6 /usr/local/zookeeper  #移动到目录
[root@node5 ~]# cd /usr/local/zookeeper/conf/   #进入到目录
[root@node5 conf]# cp zoo_sample.cfg  /opt/zoo.cfg  #复制配置文件
[root@node5 conf]# cd /opt/
[root@node5 opt]# mkdir zk1 zk2 zk3 #准备zookeeper 服务ID，每个服务器的ID是不同的
[root@node5 opt]# echo 1 > zk1/myid
[root@node5 opt]# echo 2 > zk2/myid
[root@node5 opt]# echo 3 > zk3/myid
[root@node5 opt]# vim zoo.cfg #编辑配置文件
　　dataDir=/opt/zk1 #保存数据的命令
　　clientPort=2181 #客户端连接的端口
　　server.1 = 192.168.10.205:2887:3887
　　server.2 = 192.168.10.205:2888:3888
　　server.3 = 192.168.10.205:2889:3889

[root@node5 opt]# cp zoo.cfg zk1/zk1.cfg
[root@node5 opt]# cp zoo.cfg zk2/zk2.cfg
[root@node5 opt]# cp zoo.cfg zk3/zk3.cfg

[root@node5 opt]# vim zk2/zk2.cfg #每个服务对应不同的目录
　　dataDir=/opt/zk2
　　clientPort=2182
[root@node5 opt]# vim zk3/zk3.cfg
　　dataDir=/opt/zk3
　　clientPort=2183

详细配置:

[root@node5 opt]# grep '^[a-z]' zk3/zk3.cfg
tickTime=2000 #服务器和客户端的心跳维持间隔，间隔多久发送心跳
initLimit=10 #选举的时候的时间间隔是10次，10次 * 2000微秒
syncLimit=5 # Leader 与 Follower 之间发送消息，请求和应答时间长度，最长不能超过多少个 tickTime 的时间长度
dataDir=/opt/zk3 #数据保存目录
clientPort=2181 #客户端连接的端口
server.1 = 192.168.10.205:2887:3887 #集群端口和ID配置
server.2 = 192.168.10.205:2888:3888
server.3 = 192.168.10.205:2889:3889

详细解释：
tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。
dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。
clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。
initLimit：这个配置项是用来配置 Zookeeper 接受客户端（这里所说的客户端不是用户连接 Zookeeper 服务器的客户端，而是 Zookeeper 服务器集群中连接到 Leader 的 Follower 服务器）初始化连接时最长能忍受多少个心跳时间间隔数。当已经超过 5个心跳的时间（也就是 tickTime）长度后 Zookeeper 服务器还没有收到客户端的返回信息，那么表明这个客户端连接失败。总的时间长度就是 5*2000=10 秒
syncLimit：这个配置项标识 Leader 与 Follower 之间发送消息，请求和应答时间长度，最长不能超过多少个 tickTime 的时间长度，总的时间长度就是 2*2000=4 秒
server.A=B：C：D：其中 A 是一个数字，表示这个是第几号服务器；B 是这个服务器的 ip 地址；C 表示的是这个服务器与集群中的 Leader 服务器交换信息的端口；D 表示的是万一集群中的 Leader 服务器挂了，需要一个端口来重新进行选举，选出一个新的 Leader，而这个端口就是用来执行选举时服务器相互通信的端口。如果是伪集群的配置方式，由于 B 都是一样，所以不同的 Zookeeper 实例通信端口号不能一样，所以要给它们分配不同的端口号。

启动每个zookeeper 服务：

[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  start  /opt/zk1/zk1.cfg
JMX enabled by default
Using config: /opt/zk1/zk1.cfg
Starting zookeeper ... STARTED
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  start  /opt/zk2/zk2.cfg
JMX enabled by default
Using config: /opt/zk2/zk2.cfg
Starting zookeeper ... STARTED
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  start  /opt/zk3/zk3.cfg
JMX enabled by default
Using config: /opt/zk3/zk3.cfg
Starting zookeeper ... STARTED

确认端口启动成功：

[root@node5 opt]# ss -tnl | grep 2181
LISTEN     0      50                       :::2181                    :::*
[root@node5 opt]# ss -tnl | grep 2182
LISTEN     0      50                       :::2182                    :::*
[root@node5 opt]# ss -tnl | grep 2183
LISTEN     0      50                       :::2183                    :::*
[root@node5 opt]# 

查看每个节点的状态：

[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  status /opt/zk1/zk1.cfg
JMX enabled by default
Using config: /opt/zk1/zk1.cfg
Mode: follower
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  status /opt/zk2/zk2.cfg
JMX enabled by default
Using config: /opt/zk2/zk2.cfg
Mode: leader  #这是主的，另外两个是从的，表示已经启动完成
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  status /opt/zk3/zk3.cfg
JMX enabled by default
Using config: /opt/zk3/zk3.cfg
Mode: follower

make gotest 测试过程

执行全部指令后，会在 bin 文件夹内生成 codis-config、codis-proxy、codis-server三个可执行文件。另外, bin/assets 文件夹是 codis-config 的 dashboard http 服务需要的前端资源, 需要和 codis-config 放置在同一文件夹下)

[root@node5 codis]# cd bin/
[root@node5 bin]# ls
assets  codis-config  codis-proxy  codis-server

可执行文件使用方式：

[root@node5 bin]# ./codis-config  -h

[root@node5 bin]# ./codis-config  -h 
usage: codis-config  [-c <config_file>] [-L <log_file>] [--log-level=<loglevel>]
        <command> [<args>...]
options:
   -c   #配置文件地址
   -L   #日志输出文件地址
   --log-level=<loglevel>   #输出日志级别 (debug < info (default) < warn < error < fatal)

commands:
    server            #redis 服务器组管理
    slot              #slot 管理
    dashboard         #启动 dashboard 服务
    action            #事件管理 (目前只有删除历史事件的日志)
    proxy             #proxy 管理

[root@node5 bin]# ./codis-proxy  -h

$ bin/codis-proxy -h
usage: codis-proxy [-c <config_file>] [-L <log_file>] [--log-level=<loglevel>] [--cpu=<cpu_num>] [--addr=<proxy_listen_addr>] [--http-addr=<debug_http_server_addr>]

options:
   -c    #配置文件地址
   -L    #日志输出文件地址
   --log-level=<loglevel>   #输出日志级别 (debug < info (default) < warn < error < fatal)
   --cpu=<cpu_num>      #proxy占用的 cpu 核数, 默认1, 最好设置为机器的物理cpu数的一半到2/3左右
   --addr=<proxy_listen_addr>       #proxy 的 redis server 监听的地址, 格式 <ip or hostname>:<port>, 如: localhost:9000, :9001
   --http-addr=<debug_http_server_addr>    #proxy 的调试信息启动的http server, 可以访问 http://debug_http_server_addr/debug/vars

[root@node5 bin]# ./codis-server  -h

[root@node5 bin]# ./codis-server  -h
Usage: ./redis-server [/path/to/redis.conf] [options]
       ./redis-server - (read config from stdin)  #指定redis配置文件
       ./redis-server -v or --version  #显示版本
       ./redis-server -h or --help #获取帮助
       ./redis-server --test-memory <megabytes> #单位为字节

Examples:
       ./redis-server (run the server with default conf)
       ./redis-server /etc/redis/6379.conf
       ./redis-server --port 7777
       ./redis-server --port 7777 --slaveof 127.0.0.1 8888
       ./redis-server /etc/myredis.conf --loglevel verbose

开始部署：

[root@node5 bin]# cd ..
[root@node5 codis]# vim config.ini

zk=192.168.10.205:2181
dashboard_addr=192.168.10.205:18087

配置并启动 dashboard：

[root@node5 codis]# cp config.ini  bin/ #将修改后的文件复制至bin目录，因为bin里面你的命令默认读取当前目录的config.ini文件，或可以使用 -c指定也可以

[root@node5 bin]# ./codis-config  dashboard & #该命令会启动 dashboard

启动成功就可以通过 http://ServerIP:18087访问

初始化 slots：

执行./codis-config slot init，该命令会在zookeeper上创建slot相关信息，如果提示已经初始化可以加 -f 强制

[root@node5 bin]# ./codis-config slot init -f
{
  "msg": "OK",
  "ret": 0
}

启动 Codis Redis：

如果已经启动可以跳过，如果还未启动就执行：

[root@node5 bin]# /etc/init.d/redisd  start

添加 Redis Server Group：

每一个 Server Group 作为一个 Redis 服务器组存在, 只允许有一个 master, 可以有多个 slave, group id 仅支持大于等于1的整数

添加一个master：

[root@node5 bin]# ./codis-config server add 1 localhost:6379 master
{
  "msg": "OK",
  "ret": 0
}

为master添加一个slave：

[root@node5 bin]# ./codis-config  server add 1 192.168.10.205:7009  slave

[root@node5 bin]# ./codis-config  server add 1 192.168.10.205:7009  slave

在浏览器验证：

设置 server group 服务的 slot 范围：

Codis 采用 Pre-sharding 的技术来实现数据的分片, 默认分成 1024 个 slots (0-1023), 对于每个key来说, 通过以下公式确定所属的 Slot Id : SlotId = crc32(key) % 1024 每一个 slot 都会有一个且必须有一个特定的 server group id 来表示这个 slot 的数据由哪个 server group 来提供：

如:

设置编号为[0, 511]的 slot 由 server group 1 提供服务, 编号 [512, 1023] 的 slot 由 server group 2 提供服务

[root@node5 bin]# ./codis-config slot range-set 0 511 1 online
{
  "msg": "OK",
  "ret": 0
}
[root@node5 bin]# ./codis-config slot range-set 512 1023 2 online
{
  "msg": "OK",
  "ret": 0
}

启动 codis-proxy：

[root@node5 bin]# ./codis-proxy -c config.ini -L ./log/proxy.log  --cpu=8 --addr=0.0.0.0:19000 --http-addr=0.0.0.0:11000

 / ___/ / __ \  / __  /  / /  / ___/
/ /__  / /_/ / / /_/ /  / /  (__  )
\___/  \____/  \__,_/  /_/  /____/

刚启动的 codis-proxy 默认是处于 offline状态的, 然后设置 proxy 为 online 状态, 只有处于 online 状态的 proxy 才会对外提供服务

[root@node5 bin]# ./codis-config -c config.ini proxy online proxy_1
{
  "msg": "OK",
  "ret": 0
}

注：命令格式为./codis-config -c config.ini proxy online <proxy_name> <---- proxy的id, 如 proxy_1，可以在浏览器看到
