我正在使用Nginx来提供石墨和grafana(它们都在同一台服务器上运行 - 而不是我的桌面)。我可以通过Nginx访问石墨。但是,grafana似乎无法连接到石墨(错误:Graphite HTTP请求错误)。我已经复制下面的nginx配置为grafana - 任何有关修复此问题的想法将不胜感激。 在浏览器中失败的请求URL是这个(如果我直接在浏览器中访问它,则可访问):
**http://xxx.xxx.xxx.xxx:8080/render**
Nginx默认
server {
listen 85; ##listen [::]:85; #ipv6only=on;
server_name grafana;
root /home/xxxx/grafana-1.5.3/;
index index.html index.htm;
##logging per server
access_log /var/log/nginx/grafana/access.log;
error_log /var/log/nginx/grafana/error.log;
location / {
## root /home/xxxx/grafana-1.5.3/;
}
}
config.js石墨网址(格拉法纳)
graphiteUrl: "http://xxx.xxx.xxx.xxx:8080"
修改 Graphite不需要身份验证来访问grafana。另外,我使用的是grafana v1.5.3

尝试通过nginx(相同的原点)访问石墨。只需添加新位置
即可location /render {
proxy_pass http://xxx.xxx.xxx.xxx:8080/render;
}
然后在你的grafana配置文件中更改石墨网址

我能够通过将请求更改为GET而不是POST来解决此问题。有关更多信息,请参阅此问题。 https://github.com/grafana/grafana/issues/345
我的数据源最终看起来像
datasources: {
graphite: {
type: 'graphite',
url: window.location.protocol+"//"+window.location.hostname+":"+window.location.port+"/_graphite",
default: true,
render_method: 'GET'
},
},
我仍然没有想出如何让我的石墨安装接受POST请求。即使直接查询,我也可以确定CORS不是问题。

我认为您需要在石墨的nginx配置中启用CORS。请查看:http://enable-cors.org/server_nginx.html。这是我使用此链接进行的配置:
(在我的情况下,grafana在端口8100
上公开,而石墨在端口8090
上公开;相应地进行调整(8100
- > 85
,{{1} } - > 8090
))。
8080
请注意,有趣的部分是upstream django {
# Distribute requests to servers based on client IP. This keeps load
# balancing fair but consistent per-client. In this instance we're
# only using one uWGSI worker anyway.
ip_hash;
server unix:/tmp/uwsgi.sock;
}
server {
listen yourServerIp:8090;

}
uwsgi_pass django;
include uwsgi_params;
}
}
以下的内容,django对你来说可能毫无用处。
要确保它是CORS问题,您需要检查浏览器发送的HTTP标头;如果有# CORS
标题,则表示您必须使用CORS。

如果你不能编辑NGinx配置,另一件事就是使用CORS代理。 我使用NPM包corsproxy来解决石墨CORS问题。
安装corsproxy包:
mkdir graphiteProxy
cd graphiteProxy
npm install corsproxy
echo "copy the version of http_proxy corsproxy depends on into"
echo "your local node_modules"
cp -r node_modules\corsproxy\node_modules\http-proxy node_modules\http_proxy
touch app.js
app.js:
// point the grafana config.js to your local proxy: http://localhost:8081
var cors_proxy = require('corsproxy')
var http_proxy = require('http-proxy')
cors_proxy.options = {
target : "http://{{graphiteserver}}:8080"
}
http_proxy.createServer(cors_proxy).listen(8081)
运行代理:
node app.js

我不确定OP是否已经解决了他们的问题,但这对我有用:
我把石墨和grafana放在同一个地方。石墨存在于/ grafana /
中的根和grafana这解决了跨站点脚本问题,而无需设置CORS:graphite和grafana位于同一站点上。
nginx网站配置:
upstream graphite {
server unix:///var/uwsgi/graphite-web.sock;
}
server {
listen 8080;
listen [::]:8080 ipv6only=on;
root /usr/share/graphite-web/;
server_name localhost;
location /static {
alias /usr/share/graphite-web/static;
}
location /grafana {
alias /usr/share/graphite-web/grafana;
}
location / {
uwsgi_pass graphite;
include /etc/nginx/uwsgi_params;
}
}
要访问grafana,我会去:
http://192.168.1.1:8080/grafana
(192.168.1.1是我的服务器的IP地址)
