使用官方安装脚本自动安装

安装命令如下：

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

也可以使用国内 daocloud 一键安装命令：

curl -sSL https://get.daocloud.io/docker | sh

设置docker 加速器

sudo curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://b81aace9.m.daocloud.iosudo systemctl restart docker

安装相关依赖

sudo yum -y install epel-releasesudo yum -y install python-pipsudo yum clean all

安装docker-compose 

sudo pip install docker-compose
