<http://download.redis.io/releases/redis-4.0.11.tar.gz>
3台均按以下命令安装redis
cd /usr/local
tar zxvf redis.tar.gz
mv redis-4.0.11 redis
cd redis
make MALLOC=libc
make
make install

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10.6.11.164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 10.6.11.164 6379 2
sentinel down-after-milliseconds mymaster 5000
sentinel failover-timeout mymaster 15000
sentinel auth-pass mymaster Hangzhou@123
# Generated by CONFIG REWRITE
port 26379
dir "/usr/local/redis"
sentinel config-epoch mymaster 1
sentinel leader-epoch mymaster 1
sentinel known-slave mymaster 10.6.11.189 6379
sentinel known-slave mymaster 10.6.11.201 6379
sentinel current-epoch 1
sentinel announce-ip "10.6.11.164"
配置从slave的/usr/local/redis/sentinel.conf
protected-mode no
sentinel myid 3750d9547cf4e99c142984032492d43908ed8790 #自动生成的pid文件 请根据实际情况填写
sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 10.6.11.164 6379 2
sentinel down-after-milliseconds mymaster 5000
sentinel failover-timeout mymaster 15000
sentinel auth-pass mymaster Hangzhou@123
# Generated by CONFIG REWRITE
port 26379
dir "/usr/local/redis"
sentinel config-epoch mymaster 1
sentinel leader-epoch mymaster 1
sentinel known-slave mymaster 10.6.11.189 6379
sentinel known-slave mymaster 10.6.11.201 6379
sentinel current-epoch 1
sentinel announce-ip "10.6.11.164"
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10.6.11.189为新master
再次查看哨兵信息 master 已经变化
重新启动10.6.11.164的redis 查看信息
master 并没有变回去 依旧是189为master
同时redis.conf和sentinel.conf 也都发生了变化
至此 redis集群和哨兵均安装完毕
