当尝试运行`docker version`或`docker`命令时，出现错误提示`Get http:///var/run/docker.sock/v1.20/version: dial unix /var/run/docker.sock: no such file or directory`。原因是Docker守护进程未启动。解决办法是通过`docker -d`启动Docker守护进程，但该选项已弃用，建议使用`docker daemon`。启动过程中可能遇到模块未找到的问题，需要检查系统模块。

原因：没有启动deamon

解决方案，使用docker -d启动deamon：

[root@my-orch ~]# docker -d
