阿里云CentOS7安装Docker

买了阿里云主机，由于学生有优惠，玩起来确实爽。

系统版本:

[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)

内核版本：

[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)

Docker 软件包已经包括在默认的 CentOS-Extras 软件源里。使用yum进行安装：

[[email protected] ~]# yum install docker

安装完成后，启动docker服务，并设置开机自启动：

[[email protected] ~]# systemctl start docker.service
[[email protected] ~]# systemctl enable docker.service
ln -s ‘/usr/lib/systemd/system/docker.service‘ ‘/etc/systemd/system/multi-user.target.wants/docker.service‘

搜索一下镜像:

[[email protected] ~]# docker search fedora
INDEX       NAME                                             DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED

看一下docker版本：

[[email protected] ~]# docker version
