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 ~]#

使用yum install docker安装完后启动不了

[root@apptest ~]# service docker startRedirecting 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 [dockerrepo]name=Docker Repositorybaseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/enabled=1gpgcheck=1gpgkey=https://yum.dockerproject.org/gpg [root@test yum.repos.d]# yum install docker-engine 

已安装:

  docker-engine.x86_64 0:1.10.2-1.el7.centos                                     

作为依赖被安装:

  docker-engine-selinux.noarch 0:1.10.2-1.el7.centos
