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

redirecting to /bin/systemctl start docker.service

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 ~]# systemctl status docker.service

● docker.service - docker application container engine

[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
 
[dockerrepo]
name=docker repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=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   

[root@apptest ~]# service docker start
redirecting to /bin/systemctl start docker.service
[root@apptest ~]# docker images

 或者使用以下方法

[root@apptest ~]# curl -fssl https://get.docker.com/ | sh
+ sh -c 'sleep 3; yum -y -q install docker-engine'

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
repository     tag         image id      created       size
[root@apptest ~]#
