[root@iz8vb4rhbik3h93v48ztfvz docker]# systemctl start docker
Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.

原因是修改了daemon.json文件，需要再次修改。

也就是把daemon.json改爲daemon.conf。使用mv命令修改後，docker啓動正常。

 

[root@iz8vb4rhbik3h93v48ztfvz docker]# mv daemon.json daemon.conf
[root@iz8vb4rhbik3h93v48ztfvz docker]# systemctl start docker
[root@iz8vb4rhbik3h93v48ztfvz docker]# systemctl status docker
