[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。

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。

[root@apptest ~]# yum remove docker

[root@apptest ~]# yum remove docker-selinux

[root@test yum.repos.d]# vi /etc/yum.repos.d/docker.repo

作为依赖被安装:
