1、需要修改的配置檔案項 redis.conf(1、埠prot:6380 2、pid:pidfile /var/run/redis_6380.pid 3、logfile "6380.log" 4、dbfilename dump6380.rdb)

2、啟動 redis-server  配置檔案  info replication

3、命令 人老大 從機中配置 slaveof host port  然後info replication  檢視 -----可以在配置檔案中配置 replication 選項 replicaof <masterip> <masterport> 如果有密碼  需要配置masterauth <master-password>

4、shutdown 主機斷開後叢機還是有資料儲存 需要手動修改叢機變為主機。slaveof no one 把自己變為主機master；

5、開啟哨兵模式：配置 sentinel.conf (sentinel monitor 被監控的主機名：myredis  地址：192.168.1.7  埠：6379  投票的數量1)   配置：sentinel monitor myredis 192.168.1.7 6379 1
