docker安装 centos亲测可行

     最近在群里听说docker很火，于是自己抱着试试的态度，想玩玩，可是遇到了一些问题，记录下来，方便备忘，也方便防止大家被坑。

     我的虚拟机装的是centos 6.5,百度了好多教程，丫的，都不解释，就一句命令：yum install docker-io,这句话是用源安装docker,可是源一般是国外源，用这个命令因为GFW被墙，根本安装不了。

        总共尝试了好几次，所谓的镜像很不稳定，不是没有找到，就是找到了，下了一半就中途断了，哎，网上总是说一句话搞定，可是一句话搞定要有前提呀，于是乎，我看了开源中国的docker更新记录
