打开服务器输入docker ps,输出错误
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
怀疑是不是docker.services 部署没成功，systemctl start docker 启动 docker，结果服务器还是报错
Job for docker.service failed because the control process exited with error code.
See “systemctl status docker.service” and “journalctl -xe” for details.
