**1、临时性配置**  
**1.1 一主多从**

创建3个文件夹
    mkdir /mnt/6381 /mnt/6382  /mnt/6383

启动Redis Master
    docker run -itd --name redis01-p 6381:6379 -v /mnt/6381:/data redis

启动Slave01
    docker run -itd --name redis02-p 6382:6379 -v /mnt/6382:/data redis
    192.168.1.2:6382>SLAVEOF 172.17.0.2 6379
    192.168.1.2:6382> info repication

启动slave02
    docker run -itd --name redis03 -p 6383:6379 -v /mnt/6383:/data redis
    192.168.1.3:6383>SLAVEOF  172.17.0.2 6379
    192.168.1.3:6383> info repication

**1.2、主从从**  
主从从就是把slave02的SLAVEOF指定的ip变成slave01

**1.3、从库变主库**

192.168.1.2:6383> SLAVEOF  no one

**1.4、问题**

*  临时性配置，重启失效
 *  主节点挂掉后，从节点需要手动升级主库
