docker 服务启动不起来了，各种方式尝试了，菜鸟求关爱~

看看 restart 的控制台输出，有可能进程还没死，所以起不来

@newjuzi
(base) [root@localhost ~]# systemctl restart docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
直接提示这个，然后就是我图里的样子

ps 看看 docker 进程有没有残留，有的话删掉

@newjuzi 没有残留啊

devicemapper.conf 文件里把--graph 改成--data-root

看起来可能是启动参数的问题。 就是那个 /home/docker_pro/lib/docker

journalctl -xe 就是要执行这个命令看错误的，这是看真实报错信息的命令

journalctl -u docker -f 看看？

我推测是权限问题，检查一下权限，还有如果有 SELinux 可以尝试关掉

systemctl status 显示的日志内容比较少
但实际上产生了很多，结果就导致真正想看的内容都已经“滚动”过去了

应该用 journalctl -u docker 来查看

他说 graph 这个 config file option 已经 deprecated 了。。试试换一个。 另外感觉开个 debug 看看吧。 启动命令行加个 --debug 参数

中的 graph 删除， 把
这个下边的配置文件更改一下：
/etc/systemd/system/docker.service.d
(base) [root@localhost docker.service.d]# cat devicemapper.conf
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --data-root=/home/docker_pro/lib/docker

启动成功了

你这个 service 文件从哪儿来的？不是和 docker 配套安装过来的吗？
