docker启动显示Job for docker.service failed because the control process exited with error code. 报错

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

有可能是因为卸载了docker后重装docker，需要先清理旧的docker数据

rm -rf /var/lib/docker/*

再重启就可以了
