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

?

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!
