解决grafana加载缓慢的方案

青旅半醒 2022-11-05 10:58 972阅读 0赞

最近在公司系统里做了一个内嵌grafana页面的功能，用于查看集群日志。但grafana作为一个单页面应用，加载框架资源，耗费了很长很长时间，以至于你起身去接杯水回来，页面还没有加载完毕。  
本着精益求精的思想，想着提升加载速度。 一番搜索下来。发现在grafana7.4.0以后就支持了配置cdn来加载前端资源。  
于是乎，说干就干。用我的两台服务器，一台部署grafana，一台将grafan前端资源部署起来当做cdn。 不要问我为什么不用阿里云的oss+cdn？主要是没钱。刷一下页面就是几毛钱，一般人谁受的了。其实原理是一样的。cdn可以用ip代理，可以用nginx代替。只是网络依然很慢。除非你服务器带宽很高。 顺便提一句 我们集群带宽只有5M。  
废话少说。let do it  
首先启动grafana 7.4.1版本的镜像，并映射配置文件

docker run -d -p 3000:3000 --name grafana -v /home/fizz/grafana/grafana.ini:/etc/grafana/grafana.ini  grafana/grafana:7.4.1

更多关于grafana容器的配置请查询 [此处][Link 1]

文件 `/home/fizz/grafana/grafana.ini`是 grafana的配置文件。具体内容会在文末给出。这个文件你也可以下载windows版本，在安装目录 `E:\GrafanaLabs\grafana\conf\defaults.ini` 找到。

在这里主要配置一个`cdn_url` 我们配置为 `cdn_url = http://115.159.52.223:8081`

那么我们需要将grafana 7.4.1版本的release（即发布的包，容器）放到服务器上。 使用户能够通过  
`http://115.159.52.223:8081/grafana-oss/7.4.1/public/build/moment~app.f8f20cc62ef273db5b3b.js`

**这里请一定注意 配置的是 `cdn_url = http://115.159.52.223:8081` 访问资源的链接是 `http://115.159.52.223:8081/grafana-oss/7.4.1/.....`**

这里提供一下我的做法，以供参考。

*  下载windows 7.4.1的grafana 安装到 E:\\GrafanaLabs
 *  取出 `public` 放到115服务器地址 `/home/fizz/nginx/www/grafana-oss/7.4.1` ，如我的 E:\\GrafanaLabs\\grafana\\public
 *  在服务器启动配置映射目录启动ngxinx镜像，命令 `docker run -p 8081:80 -d -v /home/fizz/nginx/www:/usr/share/nginx/html nginx`
 *  取出`E:\GrafanaLabs\grafana\conf\defaults.ini` 放到210服务器目录 `/home/fizz/grafana/grafana.ini` 并修改 `cdn_url = http://115.159.52.223:8081`
 *  在210 服务器启动grafana 命令 `docker run -d -p 3000:3000 --name grafana -v /home/fizz/grafana/grafana.ini:/etc/grafana/grafana.ini grafana/grafana:7.4.1`
 *  打开 grafana地址 `http:// ip:3000`

打开控制台，发现前端资源都已经变成配置的cdn资源了  
但有个美中不足的地方是页面的字体资源报跨域。不过这个配置跨域很简单就能解决。这边不再累述。

有关grafana的cdn pr可以[查看这个地址][Link 2]

另外官方文档这里有一个错误需要指出。就是在配置cdn路径后， grafana访问前端资源的路径是  
`http://cdn.myserver.com/grafana-oss/7.4.0/public/build/app.<hash>.js` 而不是 `http://cdn.myserver.com/grafana-oss/v7.4.0/public/build/app.<hash>.js` 文档中在版本前多了一个 **`v`**
