CentOS6.x安装docker

说明:系统版本 CentOS 6.9 X64

安装docker

配置Fedora EPEL 源

由于CentOS 6.x与7.x安装docker是有一些不同的，CentOS 6.x上docker的安装包叫docker-io，来源于Fedora epel库，这个仓库维护了大量的没有包含在发行版中的软件，所以先要安装EPEL，而CentOS 7.x的docker直接包含在官方镜像源的Extras仓库（CentOS-Base.repo下的[extras]节enable=1启用）

yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

安装docker

安装 docker-io
