哨兵模式
**
一个主机，3个端口的哨兵
6379端口为master
16379为slave
26379为sentinel**

slaveof 192.168.145.132 6379 //master节点配置
启动slave，修改端口为16379启动即可
docker run --name redis_slave -p 16379:6379 -v $(pwd)/redis_slave.conf:/data/redis_slave.conf --restart=always -d redis:5.0.5 redis-server redis_slave.conf
哨兵sentinel配置文件
daemonize no
port 26379 哨兵节点的端口
dir "/tmp"

sentinel down-after-milliseconds mymaster 60000
sentinel auth-pass mymaster password
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
启动哨兵，修改端口26379
docker run --name sentinel -p 26379:6379 -v $(pwd)/sentinel.conf:/data/sentinel.conf --restart=always -d redis:5.0.5 redis-sentinel sentinel.conf
查看主节点信息
docker inspect redis_slave | grep IPA
docker run -it redis redis-cli -p 6379 -h 172.17.0.5进入容器，查看信息
进入从节点
每个节点执行哨兵
docker exec -it redis_master /bin/bash
touch sentinel.conf && touch log.txt
echo 'sentinel monitor mymaster 192.168.145.132 6379 1' > sentinel.conf
echo 'logfile "/data/log.txt"' >> sentinel.conf
echo 'daemonize yes' >> sentinel.conf
redis-sentinel sentinel.conf
