docker 常见错误

服务启动失败

# 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

解决方法

修改/etc/docker/daemon.json文件(json格式不正确docker也是无法启动)

# vim  /etc/docker/daemon.json 
{
    "storage-driver":"devicemapper"
}

然后重启服务即可。
