docker pull redis
2.1.1. Master node:
bind 0.0.0.0 protected-mode no //redis配置访问密码 requirepass 123456 //主节点密码 哨兵模式下主节点宕机从新恢复变成从节点 需要密码 masterauth 123456
2.1.2. Slave node:
bind 0.0.0.0 protected-mode no requirepass 123456 //主节点访问密码 masterauth 123456 //主节点信息 slaveof *.*.*.* 6379

### 在主节点查看 # 进入容器内部 docker exec -it redis bash # 进入redis redis-cli # 校验密码 auth 123456 # 查看集群信息 info replication
#### 根据需要修改一下内容 # 让sentinel服务后台运行(docker的话需要设置为no,非docker运行设置为yes, 因为docker有个-d属性就是让在后台运行的) daemonize no # 修改日志文件的路径 logfile "/data/sentinel.log" # 修改监控的主redis服务器 # 最后一个2表示,两台机器判定主被动下线后,就进行failover(故障转移) sentinel monitor mymaster *.*.*.*(公网ip) 6390 2 #超过5秒master还没有连接上,则认为master已经停止 sentinel down-after-milliseconds mymaster 5000 sentinel auth-pass mymaster 123456
# /usr/local/redis cd /usr/locar/redis-sentinel mkdir conf mkdir data
docker run -d --name sentinel -p 26379:26379 \ -v /usr/local/redis-sentinel/conf/sentinel.conf:/etc/sentinel.conf \ -v /usr/local/redis-sentinel/data:/data redis redis-sentinel /etc/sentinel.conf

Close the master node
Execute multiple times "info replication" command to observe the changes in information after executing the 2.4 verification module built by the master-slave cluster
or monitor the log file of the sentinel configuration, you can see its occurrence in real time The change
