1、启动时候显示启动错误，查看信息，发现是配置信息错误


[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

常见于更改配置文件之后docker不能正常启动

查看 /etc/docker ,存在daemon.json文件，修改之后，还是不能正常启动

删除该文件，docker就能正常启动


2、当pull或者push时候，出现EOF错误


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


使用下面方法解决：

vim /etc/sysconfig/docker     #如果使用的是docker-latest，在对应位置修改该配置增加下面这行
OPTIONS='--insecure-registry 10.74.29.152:5000'
