在Centos7 成功安装，但是启动不了，报错如下：

[root@localhost ~]# 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@localhost ~]# 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.

**解决方案如下： **

[root@localhost ~]# yum remove docker [root@localhost ~]# yum remove docker-selinux [root@localhost ~]# vi /etc/yum.repos.d/docker.repo 在这个文件里面输入如下： [dockerrepo] name=Docker Repository baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/ enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg

接着：

[root@localhost ~]# 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

之后就可以成功启动，如下：
