Docker在CentOS 7下的安裝
一、檢查前提條件
1.內核
檢查內核的版本是否安裝了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.檢查Device Mapper
[root@localhost ~]# ls -l /sys/class/misc/device-mapper/
總用量 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文件中檢查是否有device-mapper條目
[root@localhost ~]# grep device-mapper /proc/devices
253 device-mapper
二、安裝Docker
[root@localhost ~]# yum -y install docker
已加載插件：fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
* epel: ftp.sjtu.edu.cn
* extras: mirrors.btte.net
* updates: mirrors.neusoft.edu.cn

三、啟動Docker進程
[root@localhost ~]# systemctl start docker
如果想在開機的時間自動啟動Docker服務，執行如下命令
[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是否運行
[root@localhost ~]# docker info
