Hi all:
在CentOS7上执行yum install docker安装docker后，对docker进行测试出现如下错误：
[root@localhost /]# docker run -i -t ubuntu /bin/bash
2014/11/27 15:21:52 Post http:///var/run/docker.sock/v1.14/containers/create: read unix /var/run/docker.sock: connection reset by peer
搜索后得知是没有启动docker服务，执行启动服务失败：
[root@localhost /]# systemctl start docker.service
Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details.
[root@localhost /]# systemctl status docker.service

请问是什么问题？？？
需要安装 device-mapper-event-libs 才可以使用。安装 docker 后只需执行 sudo yum install device-mapper-event-libs 即可。
安装 device-mapper-event-libs
启动的时候 sudo systemctl start docker 可以么？
到/var/run把docker.pid删掉重启可以么
貌似我之前修改了/etc/selinux/config，把SELINUX=enforcing改成了SELINUX=disabled。改回去就可以了
