redis5.0.9哨兵模式redis-sentinel

Posted 2020-12-22

环境规划部署

ip地址	规划节点
192.168.31.177	Master redis-sentinel
192.168.31.178	Slave1 redis-sentinel
192.168.31.179	Slave2 redis-sentinel

部署redis 配置主从

我这里是安装一键部署的
    wget -c http://mirrors.linuxeye.com/oneinstack-full.tar.gz

配置主从（192.168.31.178和192.168.31.179配置）

192.168.31.178 配置
      bind 127.0.0.1 192.168.31.178    #修改
      slaveof 192.168.31.177 6379        #新增
      masterauth  # #这里填写客户端设置的密码    requirepass 我这里没有设置密码
192.168.31.179 配置 
       bind 127.0.0.1 192.168.31.179    #修改
       slaveof  192.168.31.177 6379        #新增
       masterauth   #这里填写客户端设置的密码    requirepass 我这里没有设置密码
                 重启各自的redis-server即可

部署redis-sentinel环境（192.168.31.177）

[root@server1 etc]# cat sentinel.conf 
   # 端口
   port 26379
   # 日志文件
   logfile "/usr/local/redis/var/sentinel.log"
  #放后台启动
   daemonize yes
  # 哨兵监控主节点的IP和端口   2表示至少一个节点认为主节点down了，才开始选举新节点
   sentinel monitor hanye 192.168.31.177 6379 2
  # 多少毫秒没有接收到主节点的反馈，认为主节点down
   sentinel down-after-milliseconds hanye 15000
  #数据存放位置
   dir "/usr/local/redis/etc"
   protected-mode no
   # failover过期时间
   sentinel failover-timeout hanye 120000
   # 配置哨兵连接主节点的认证密码。（主节点配置的requirepass）
   #sentinel auth-pass hanye null     
 然后把此配置文件复制其他server
 [root@server1 etc]# scp  /usr/local/redis/etc/sentinel.conf  192.168.31.178:/usr/local/redis/etc/
 [root@server1 etc]# scp  /usr/local/redis/etc/sentinel.conf  192.168.31.179:/usr/local/redis/etc/     

启动redis-sentinel(全部主机)

 /usr/local/redis/bin/redis-sentinel  /usr/local/redis/etc/sentinel.conf
启动完毕  redis-sentine 会在各自的配置文件添加数据

   [root@server2 ~]# cat /usr/local/redis/etc/sentinel.conf 
 # 端口
 port 26379
 # 日志文件
 logfile "/usr/local/redis/var/sentinel.log"
 daemonize yes
 sentinel myid 0e45194a89320d71313365f6163b691f1c9af021
 sentinel deny-scripts-reconfig yes
 sentinel monitor hanye 192.168.31.178 6379 2
 sentinel down-after-milliseconds hanye 15000
 # Generated by CONFIG REWRITE
 dir "/usr/local/redis/etc"
 protected-mode no
 sentinel failover-timeout hanye 120000

 sentinel leader-epoch hanye 3

检测redis-sentinel结果

停止192.168.1.177的redis

  [root@server1 etc]# kilall redis-server

停止178 redis-server
