• 依次启动redis

率先启动master redis 然后依次启动slave

/usr/local/redis/src/redis-server /usr/local/redis/redis.conf

可以在/usr/local/redis/redis.log 中 看到3台机子连接成功的信息

 

也可以在redis中 添加key 测试是否会同步

在192.168.1.111上执行如下命令

 

在slave机子上执行如下操作，会看到slave 上有和master 一样的key 名，value也一致

 

配置sentinel 哨兵

• 配置主master的/usr/local/redis/sentinel.conf

protected-mode no
sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 192.168.1.111 6379 2
sentinel down-after-milliseconds mymaster 5000
sentinel failover-timeout mymaster 15000
sentinel auth-pass mymaster 密码
 # Generated by CONFIG REWRITE 
port 26379 
dir "/usr/local/redis"
sentinel config-epoch mymaster 1
sentinel leader-epoch mymaster 1
sentinel known-slave mymaster 192.168.1.112 6379
sentinel known-slave mymaster 192.168.1.113 6379
sentinel current-epoch 1
sentinel announce-ip "192.168.1.111"

protected-mode no 
sentinel myid 3750d9547cf4e99c142984032492d43908ed8790
sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 192.168.1.111 6379 2
sentinel down-after-milliseconds mymaster 5000
sentinel failover-timeout mymaster 15000
sentinel auth-pass mymaster 密码
# Generated by CONFIG REWRITE
port 26379
dir "/usr/local/redis" 
sentinel config-epoch mymaster 1 
sentinel leader-epoch mymaster 1
sentinel known-slave mymaster 192.168.1.112 6379
sentinel known-slave mymaster 192.168.1.113 6379
sentinel current-epoch 1
sentinel announce-ip "192.168.1.111"

• 完成配置之后 依次启动哨兵sentinel

首先启动master 然后slave

/usr/local/redis/src/redis-sentinel /usr/local/redis/sentinel.conf &

启动完毕后可以用如下命令查看哨兵信息

**redis-cli -p 26379 INFO Sentinel **

 

• 测试杀死master redis 进程

 

查看日志 master 重新选举192.168.1.112为新master

 

再次查看哨兵信息 master 已经变化

 

重新启动192.168.1.111的redis 查看信息

至此 redis集群和哨兵均安装完毕
