service failed because start of the service was attempted too often（服务失败，因为尝试启动服务的次数太多。）

今天在进行docker搭建私有仓库时，重新启动docker时，发现启动不了docker服务，一头雾水，出现了如下错误，翻阅了资料后得知，原来如此简单

Job for failed because start of the service was
attempted too often. See “systemctl status ” and
“journalctl -xe” for details. To force a start use “systemctl
reset-failed ” followed by “systemctl start
” again.

启动Docker时发生错误

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

解决办法

[root@bogon ~]# cd /etc/docker
[root@bogon docker]# ll
总用量 8
-rw-r--r--. 1 root root 110 8月  19 09:16 
-rw-------. 1 root root 244 8月  19 02:30 
[root@bogon docker]# mv  

修改后缀为.conf
