三个 Master， 端口号 7001， 7002， 7003
三个 Slave，端口号 7004， 7005， 7006
两个 Sentinel 端口号26378， 26379

sentinel failover-timeout mymaster1 180000

sentinel failover-timeout mymaster3 180000
sentinel parallel-syncs mymaster1 1
sentinel parallel-syncs mymaster2 1
sentinel parallel-syncs mymaster3 1

启动sentinel：redis-server.exe sentinel.conf --sentinel

两个sentinel会自动探测到对方。sentinel也会自动更新自己的配置文件sentinel.conf 。7001挂了以后，7004会自动成为Master。等到7001重启后会成为7004的Slave。

打开控制台，可以连接任意一台 Master
redis-cli.exe -p 7001

查看cluster: cluster nodes. 查看当前master 和slave情况。
