CentOS7安装docker解决启动不了的问题
CentOS7安装docker 启动不了，在⼯作当中遇到这个问题，当时急的不清，⽹上资料⼜不多，不过经过⾃⼰的捣⿎终于解决了
这个问题！
[root@test ~]# yum update
[root@test ~]# yum install docker
[root@test ~]# service docker start

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

[root@test ~]#
使⽤yum install docker安装完后启动不了
[root@apptest ~]# service docker start
Redirecting to /bin/systemctl start docker.service
⼀直停留在以上步骤
可以使⽤以下命令来安装，即可成功。
exited⼀个问题让我折腾了两天，试过关闭防⽕墙，关闭selinux，重装系统，等等⽹上能查到的⽅法都解决不了。
如果⼤家解决了，回复感谢下我吧。

Cannot connect to the Docker daemon. Is the docker daemon running on this host?
If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
[root@apptest ~]#
[root@apptest ~]# service docker start
Redirecting to /bin/systemctl start docker.service
[root@apptest ~]# docker images
