grafana的配置文件

grafana的配置文件

很多时候，组件都是需要自定义安装，所以我们必须要了解组件的配置文件，然后根据自己的需求修改配置文件。

app_mode：应用名称，默认是production

login_remember_days：多少天内保持登录状态
secret_key：保持登录状态的签名

[users]
allow_sign_up：是否允许普通用户登录，如果设置为false，则禁止用户登录，默认是true，则admin可以创建用户，并登录grafana
allow_org_create：如果设置为false，则禁止用户创建新组织，默认是true
auto_assign_org：当设置为true的时候，会自动的把新增用户增加到id为1的组织中，当设置为false的时候，新建用户的时候会新增一个组织

grafana自定义的URL

这个需求，我还是找了好几天的，毕竟第一次搞这样的配置；很多东西都是在网站上找，不断的去修改，去验证；虽然比较难，但是终于实现了，真不错。 需求是这样的： 加一层目录 3000：grafana/d 在配置的过程中遇到过很多的错误，比如比较常见的错误：

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: yarn start, yarn start:hot, or yarn build

4. Sometimes restarting grafana-server can help

如果您看到此Grafana无法加载其应用程序文件
 
 1。可能是由您的反向代理设置引起的。 
 
 2.如果在子路径下托管grafana，请确保您的grafana.ini root_url设置包括子路径
 
 3.如果您具有本地开发版本，请确保使用以下命令构建前端：纱线开始，纱线开始：热或构建纱线
 
 4.有时重新启动grafana服务器可以帮助

在这个时候我是非常想放弃的了，但是最后我还是坚持了下来，继续寻找答案。

现在更改了路径，依然可以访问grafana啦。之前一直访问失败是因为一个重要的参数我的文件里没有，后面百度了很久，我找到了。参考链接：grafana官方文档 serve_from_sub_path

#这个参数很重要
# Serve Grafana from subpath specified in `root_url` setting. By default it is set to `false` for compatibility reasons.
