序
这里参照了Docker 搭建redis 集群这篇文章来，非常顺利。
下载镜像
docker pull redis准备配置文件
mkdir /home/docker/redis/
wget https://raw.githubusercontent.com/antirez/redis/3.0/redis.conf -O /home/docker/redis/redis.conf
cd /home/docker/redis/
sed -i 's/# slaveof <masterip> <masterport>/slaveof redis-master 6379/g' redis.conf 启动redis容器
docker run --name redis-master -p 6379:6379 -d redis
docker run --link redis-master:redis-master -v /home/docker/redis/redis.conf:/usr/local/etc/redis/redis.conf --name redis-slave1 -d redis redis-server /usr/local/etc/redis/redis.conf
docker run --link redis-master:redis-master -v /home/docker/redis/redis.conf:/usr/local/etc/redis/redis.conf --name redis-slave2 -d redis redis-server /usr/local/etc/redis/redis.conf
docker run --link redis-master:redis-master -v /home/docker/redis/redis.conf:/usr/local/etc/redis/redis.conf --name redis-slave3 -d redis redis-server /usr/local/etc/redis/redis.conf 查看redis集群
