配置哨兵

wget http://download.redis.io/redis-stable/sentinel.conf

配置sentinel.conf

sentinel monitor mymaster 127.0.0.1 6300 2
sentinel auth-pass mymaster 123456
daemonize yes

启动sentinel实例：

docker run -it --name redis-sentinel1 -v /D/Workspace/Docker/docker-install-redis-cluster/sentinel1.conf:/usr/local/etc/redis/sentinel.conf -d redis /bin/bash
docker exec -it redis-sentinel1 bash
redis-sentinel /usr/local/etc/redis/sentinel.conf

docker run -it --name redis-sentinel2 -v /D/Workspace/Docker/docker-install-redis-cluster/sentinel2.conf:/usr/local/etc/redis/sentinel.conf -d redis /bin/bash
docker exec -it redis-sentinel2 bash
redis-sentinel /usr/local/etc/redis/sentinel.conf

docker run -it --name redis-sentinel3 -v /D/Workspace/Docker/docker-install-redis-cluster/sentinel3.conf:/usr/local/etc/redis/sentinel.conf -d redis /bin/bash
docker exec -it redis-sentinel3 bash
redis-sentinel /usr/local/etc/redis/sentinel.conf
