Docker在CentOS 7下的安装
一、检查前提条件
1.内核
检查内核的版本是否安装了3.8或更高的版本
[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0-123.13.2.el7.x86_64 #1 SMP Thu Dec 18 14:09:13 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
2.检查Device Mapper
[root@localhost ~]# ls -l /sys/class/misc/device-mapper/
总用量 0
-r–r–r–. 1 root root 4096 12月 28 17:18 dev
drwxr-xr-x. 2 root root 0 12月 28 17:14 power
lrwxrwxrwx. 1 root root 0 12月 28 17:18 subsystem -> ../../../../class/misc
-rw-r–r–. 1 root root 4096 12月 28 17:13 uevent
或者在/proc/device文件中检查是否有device-mapper条目
[root@localhost ~]# grep device-mapper /proc/devices
253 device-mapper
二、安装Docker
[root@localhost ~]# yum -y install docker
已加载插件：fastestmirror

* epel: ftp.sjtu.edu.cn
* extras: mirrors.btte.net
* updates: mirrors.neusoft.edu.cn

完毕！
三、启动Docker进程
[root@localhost ~]# systemctl start docker
如果想在开机的时间自动启动Docker服务，执行如下命令
[root@localhost ~]# systemctl enable docker
ln -s ‘/usr/lib/systemd/system/docker.service’ ‘/etc/systemd/system/multi-user.target.wants/docker.service’
查看Docker是否运行
[root@localhost ~]# docker info
