redis集群配置要点

1、需要修改的配置文件项 redis.conf(1、端口prot:6380 2、pid:pidfile /var/run/redis_6380.pid 3、logfile "6380.log" 4、dbfilename dump6380.rdb)

2、启动 redis-server  配置文件  info replication

3、命令 人老大 从机中配置 slaveof host port  然后info replication  查看 -----可以在配置文件中配置 replication 选项 replicaof <masterip> <masterport> 如果有密码  需要配置masterauth <master-password>

4、shutdown 主机断开后丛机还是有数据保存 需要手动修改丛机变为主机。slaveof no one 把自己变为主机master；

5、开启哨兵模式：配置 sentinel.conf (sentinel monitor 被监控的主机名：myredis  地址：192.168.1.7  端口：6379  投票的数量1)   配置：sentinel monitor myredis 192.168.1.7 6379 1
