1、啓動時候顯示啓動錯誤，查看信息，發現是配置信息錯誤
[root@localhost docker]# service docker start
Redirecting to /bin/systemctl start docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
[root@localhost docker]# systemctl status docker.service

常見於更改配置文件之後docker不能正常啓動
查看 /etc/docker ,存在daemon.json文件，修改之後，還是不能正常啓動
刪除該文件，docker就能正常啓動
2、當pull或者push時候，出現EOF錯誤
docker pull 10.74.120.151:5000/clusterhqci/fpm-centos-7
Using default tag: latest
Trying to pull repository 10.74.120.151:5000/clusterhqci/fpm-centos-7 ...
Get https://10.74.120.151:5000/v1/_ping: EOF
使用下面方法解決：
vim /etc/sysconfig/docker #如果使用的是docker-latest，在對應位置修改該配置增加下面這行
OPTIONS='--insecure-registry 10.74.29.152:5000'
