在自己的测试服务器装起了docker，安装成功，but，启动失败了，解决后，在此记录下～

安装环境

 [root@fantasykai ~]# uname -r
 3.10.0-514.26.2.el7.x86_64
 [root@fantasykai ~]# lsb_release -a
 LSB Version:	:core-4.1-amd64:core-4.1-noarch
 Distributor ID:	CentOS
 Description:	CentOS Linux release 7.3.1611 (Core)
 Release:	7.3.1611
 Codename:	Core

安装docker

yum -y install docker

启动docker

启动报错：

[root@fantasykai ~]# service docder start
Redirecting to /bin/systemctl start  docder.service
Failed to start docder.service: Unit not found.

解决方式：

新建一个docker.socket 文件

vim /usr/lib/systemd/system/docker.socket

[Unit]
Description=Docker Socket for the API
PartOf=docker.service

[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
SocketGroup=docker

[Install]
WantedBy=sockets.target

然后运行

systemctl daemon-reload
systemctl start docker.socket
systemctl start docker

OK，启动好了，可以在愉快的玩耍了～
