1、在linux系统中进入到哨兵配置文件所在目录
vi sentinel.conf
更改具体信息，保存。
2、重启redis
ps -ef |grep redis
查看进程，删除哨兵进程,
kill 15 进程数。 ----15 也可以用9 ，但是15的话，会让redis保存后再停止。
3、更改日志路径
nohup /usr/redis/redis_slave1/redis-server /usr/redis/redis_slave1/conf/sentinel.conf --sentinel > /data/redis/logs/sentinel.log 2>&1 &
4、查看redis是否已经启动，
ps -ef |grep redis
more /data/redis/logs/sentinel.log
5、指定访问redis的端口
注意有点：./redis-cli -p 26380
6、查看主从配置是否正确
sentinel slaves master
