centos docker安装

[dev@OG2233-FM41-226 tmp]$ sudo yum -y install docker-io
这个应该是centos6的安装，如果安装不了试一下安装epel源，如下：

sudo yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
[dev@OG2233-FM41-226 tmp]$ vi /etc/sysconfig/docker
other-args列更改为：other_args="--exec-driver=lxc --selinux-enabled"

[dev@OG2233-FM41-226 tmp]$ sudo service docker start
