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没有找到docker包，更新epel第三方软件库，运行命令：sudo yum install epel-release ，之后再执行：sudo yum install docker
四、开机自启动与启动Docker
1 [root@localhost opt]# service docker start2 Starting cgconfig service: [ OK ]3 Starting docker: [ OK ]
[root@localhost opt]# chkconfig docker on[root@localhost opt]# chkconfig docker --listdocker 0:off 1:off 2:on 3:on 4:on 5:on 6:off
至此docker已经安装完成.
