docker启动报错：Job for docker.service failed because the control process exited with error code.
问题描述
1、检查docker的运行状态
Failed to start Docker Application Container Engine.
2、尝试重启docker服务
[root@vm37-206 ~]# systemctl start docker
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：
修改配置文件后缀 —>把/etc/docker/daemon.json文件的.json后缀，修改为.conf后缀
[root@master ~]# mv /etc/docker/daemon.json /etc/docker/daemon.conf
[root@vm37-206 ~]# systemctl start docker
