### 一主二从 ###

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

# 主库
    docker run --name redis-master -d -p 6300:6300 -v /D/Workspace/Docker/docker-install-redis-cluster/redis.conf:/etc/redis/redis.conf redis redis-server /etc/redis/redis.conf --requirepass 123456 --port 6300
    docker exec -it redis-master bash
    redis-cli -a 123456 -p 6300
    config set masterauth 123456
    
    #从库1
    docker run --name redis-slave1 -d -p 6301:6301 redis redis-server --requirepass 123456 --port 6301
    docker exec -it redis-slave1 bash
    redis-cli -a 123456 -p 6301
    slaveof 127.0.0.1 6300
    config set masterauth 123456
    
    #从库1
    docker run --name redis-slave2 -d -p 6302:6302 redis redis-server --requirepass 123456 --port 6302
    docker exec -it redis-slave2 bash
    redis-cli -a 123456 -p 6302
    slaveof 127.0.0.1 6300
    config set masterauth 123456

## 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

## 验证 ##

# 主库
    docker exec -it redis-master bash
    redis-cli -a 123456 -p 6300 DEBUG sleep 60
    
    # 从库
    docker exec -it redis-slave1 bash
    info Replication
    
    docker exec -it redis-slave2 bash
    info Replication
