问题描述
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/bash2014/11/27 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.serviceJob for docker.service failed. See ’systemctl status docker.service’ and ’journalctl -xn’ for details.[root@localhost /]# systemctl status docker.servicedocker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled) Active: failed (Result: start-limit) since Thu 2014-11-27 15:03:24 CST; 13s ago Docs: http://docs.docker.io Process: 4559 ExecStart=/usr/bin/docker -d $OPTIONS $DOCKER_STORAGE_OPTIONS (code=exited, status=1/FAILURE) Main PID: 4559 (code=exited, status=1/FAILURE)Nov 27 15:03:24 localhost.localdomain systemd[1]: docker.service: main proces...Nov 27 15:03:24 localhost.localdomain systemd[1]: Failed to start Docker Appl...Nov 27 15:03:24 localhost.localdomain systemd[1]: Unit docker.service entered...Nov 27 15:03:24 localhost.localdomain systemd[1]: docker.service holdoff time...Nov 27 15:03:24 localhost.localdomain systemd[1]: Stopping Docker Application...Nov 27 15:03:24 localhost.localdomain systemd[1]: Starting Docker Application...Nov 27 15:03:24 localhost.localdomain systemd[1]: docker.service start reques...Nov 27 15:03:24 localhost.localdomain systemd[1]: Failed to start Docker Appl...Nov 27 15:03:24 localhost.localdomain systemd[1]: Unit docker.service entered...Hint: Some lines were ellipsized, use -l to show in full.

问题解答
回答1：You need to install device-mapper-event-libs and then it works. Just do sudo yum install device-mapper-event-libs after you install docker.
回答2：yum install device-mapper-event-libs
安装 device-mapper-event-libs
回答3：启动的时候 sudo systemctl start docker 可以么？
回答4：到/var/run把docker.pid删掉重启可以么
回答5：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
