1.  1.  **Docker安装前相关配置**

\#替换Centos7的yum源镜像为阿里yum镜像

\#\#备份原有yum仓库

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

\#\#下载镜像覆盖原有镜像仓库

wget -O /etc/yum.repos.d/CentOS-Base.repo [http://mirrors.aliyun.com/repo/Centos-7.repo][http_mirrors.aliyun.com_repo_Centos-7.repo]

\#\#添加epel

wget -O /etc/yum.repos.d/epel.repo [http://mirrors.aliyun.com/repo/epel-7.repo][http_mirrors.aliyun.com_repo_epel-7.repo]

\#\#清理和更新缓存

yum clean all

yum makecache

\#校验是否已安装docker和相关的以来支持

rpm -qa|grep docker
