前言

最近在用docker方式安装Grafana时，服务器拉取遇到下面的报错，其根本原因是链接docker.io的问题，下面简单记录下解决方法

报错信息：

Using default tag: latest
Trying to pull repository docker.io/grafana/grafana ...

解决方法：
vim /etc/docker/daemon.json

{
        "registry-mirrors": ["https://registry.docker-cn.com","https://nrbewqda.mirror.aliyuncs.com","https://dmmxhzvq.mirror.aliyuncs.com"]
}

执行命令：systemctl restart docker
再次拉取pull的时候，就可以了。

其他

报错信息：

# 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.

如果重启时遇到上面这种报错信息，有可能是在/etc/sysconfig/docker文件中registry-mirrors配置重复了，删除后重启即可解决。
