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/data/docker/redis/    wget https://raw.githubusercontent.com/antirez/redis/3.0/redis.conf \    -O /data/docker/redis/redis.conf  cd /data/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 /data/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 /data/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 /data/docker/redis/redis.conf:/usr/local/etc/redis/redis.conf --name redis-slave3 -d redis redis-server /usr/local/etc/redis/redis.conf
