启动三台 ./redis-server start

查看状态

redis-cli -h 10.102.0.33 -p 6379 -a 6S9rpmPQxAbvdyKV info

redis-cli -h 10.102.0.34 -p 6379 -a 6S9rpmPQxAbvdyKV info

redis-cli -h 10.102.0.35 -p 6379 -a 6S9rpmPQxAbvdyKV info

角色和主从的状态

安装sentinel，

三台一样的sentinel.conf

port 26379
pidfile "/usr/local/redis/var/redis-sentinel.pid"
dir "/usr/local/redis/data/sentinel"
daemonize yes
protected-mode no
logfile "/usr/local/redis/var/redis-sentinel.log"
sentinel myid 453a6c2a79774552bb7995661534da0cbf85caff
sentinel deny-scripts-reconfig yes
sentinel monitor redisMaster 10.102.0.34 6379 2
sentinel down-after-milliseconds redisMaster 10000
sentinel failover-timeout redisMaster 60000
sentinel auth-pass redisMaster 6S9rpmPQxAbvdyKV

启动

sentinel /usr/local/redis/etc/sentinel.conf

查看三台的状态

[root@redis_1 init.d]# redis-cli -h 10.102.0.33 -p 26379 info Sentinel
