1、首先关闭selinux：
setenforce 0 sed -i '/^SELINUX=/c\SELINUX=disabled' /etc/selinux/config
2、在Fedora EPEL源中已经提供了docker-io包，下载安装epel：
rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm sed -i 's/^mirrorlist=https/mirrorlist=http/' /etc/yum.repos.d/epel.repo
3、yum安装docker-io：
yum -y install docker-io
Loaded plugins: fastestmirror, security
