Docker-docke服务启动报错：Job for docker.service failed because the control process exited with error code。

省流

关闭防火墙

 systemctl stop firewalld

网上搜了好几篇，大致策略是

• 排查报错日志
• 重装docker
• daemon.json文件配置问题（标点符号）
• /var/run/ 下docker相关文件权限问题

搞了好几天，反复修改配置文件和重新安装docker都不行。
最后看到一篇帖子原来是防火墙的问题。

问题描述

[root@localhost ~]# 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.

确保卸载干净重装docker后问题不变的话，就想想排除电脑本身原因吧。
