启动所有的redis服务
/usr/local/redis/bin/redis-server /usr/local/redis/redis.conf
启动所有的sentinel（哨兵）服务
/usr/local/redis/bin/redis-sentinel /usr/local/redis/sentinel/sentinel.conf
登录redis客户端
/usr/local/redis/bin/redis-server -a oumiga -p 192.168.134.71 -p 6379
查询集群信息
##登录成功后
info replication
***注意：请注意配置文件里面带注释的属性
springboot集成redis哨兵采坑记录
如果redis因为服务器的cpu过高、内存过高、硬盘存储空间不足而导致的redis服务读取异常，redis哨兵已经切换redis服务，java客户端还是有一直报读取错误，无法切换到其它服务节点，请尝试将springboot版本升级到2.3.0，或者将redis的start jar包升级到更高版本
