在CentOS6.8下安装Docker

一、查看系统版本

[root@localhost opt]# uname -a 
Linux localhost.localdomain 2.6.32-642.el6.x86_64 #1 SMP Tue May 10 17:27:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost opt]# cat /etc/redhat-release 
CentOS release 6.8 (Final)

二、安装EPEL

因为系统自带的repo中不带docker需要安装epel

1 rpm -Uvh http://ftp.riken.jp/Linux/fedora/epel/6Server/x86_64/epel-release-6-8.noarch.rpm

三、安装Docker

yum install -y docker-io

四、开机自启动与启动Docker

1 [root@localhost opt]# service docker start
2 Starting cgconfig service:                                 [  OK  ]
3 Starting docker:                                       [  OK  ]

[root@localhost opt]# chkconfig docker on
[root@localhost opt]# chkconfig docker --list
docker          0:off   1:off   2:on    3:on    4:on    5:on    6:off

至此docker已经安装完成.
