原来使用sqlite3存储，要改为MySQL存储数据，按照
https://blog.csdn.net/u012062455/article/details/81114910
这个方法改了/etc/grafana/grafana.ini，但是没有生效，又改了**defaults.ini，重启成功**后数据库的表有了，但是访问不了了
#修改ini配置：
;type = mysql
;host = 192.168.0.166:3306
;name = grafana
;user = grafana
;password =grafana
;url = mysql://grafana:grafana@192.168.0.166:3306/grafana
;provider = mysql
;provider_config = grafana:grafana@tcp(192.168.0.166:3306)/grafana
页面 http://192.168.0.166:3000/grafana 展示：
If you're seeing this Grafana has failed to load its application files
1. This could be caused by your reverse proxy settings.
2. If you host grafana under subpath make sure your grafana.ini root_url setting includes subpath
3. If you have a local dev build make sure you build frontend using: npm run dev, npm run watch, or npm run build
4. Sometimes restarting grafana-server can help
服务是好的
