CentOS7 启动docker.service失败

Question

Hiall:
在CentOS7上执行yuminstalldocker安装docker后，对docker进行测试出现如下错误：
[root@localhost/]#dockerrun-i-tubuntu/bin/bash
2014/11/2715:21:52Posthttp:///var/run/docker.sock/v1.14/containers/create:readunix/var/run/docker.sock:connectionresetbypeer
搜索后得知是没有启动docker服务，执行启动服务失败：
[root@localhost/]#systemctlstartdocker.service
Jobfordocker.servicefailed.See'systemctlstatusdocker.service'and'journalctl-xn'fordetails.
[root@localhost/]#systemctlstatusdocker.service

如果是配置了国内镜像，并且镜像文件为/etc/docker/daemon.json，则修改文件后缀为.conf即可正常启动docker服务
