使用 Grafana 的反向代理 (nginx)

Question

我已按照 Grafana (https://grafana.com/tutorials/run-grafana-behind-a-proxy/#1) 提供的说明进行操作，但仍然没有成功。下面是我的 nginx 配置文件。问题是当我转到 http://www.example.com/grafana 时，它会将我重定向到返回 404 的 www.example.com/login。感谢您的帮助！

NGINX 配置文件

server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # Portainer
    location /portainer/ {
      proxy_http_version 1.1;
      proxy_set_header Connection "";
      proxy_pass http://www.example.com:9000/;
    }
    location /portainer/ws/ {
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      proxy_http_version 1.1;
      proxy_pass http://www.example.com:9000/ws/;
    }

    # Grafana
    location /grafana/ {
        proxy_pass   http://www.example.com:3000/;
    }
}

Grafana 配置文件

#################################### Server ####################################

# Protocol (http, https, h2, socket)

# The ip address to bind to, empty will bind to all interfaces

# The public facing domain name used to access grafana from a browser

# Redirect to correct domain if host header does not match domain

# The full public facing url you use in browser, used for redirects and emails

;root_url = %(protocol)s://%(domain)s:%(http_port)s/grafana/

# Serve Grafana from subpath specified in `root_url` setting. By default it is set to `false` for compatibility reasons.
;serve_from_sub_path = true

Answer 1

在您的 Grafana 配置文件中，root_url 和 serve_from_sub_path 似乎在注释中，请尝试删除 ; 并重新加载 NGINX

Answer 2

我认为您必须在 proxy_pass url 中添加“grafana”：

# Grafana
location /grafana/ {
    proxy_pass   http://www.example.com:3000/grafana/;
}

Answer 3

如果 grafana 在子路径上运行反向代理，则在 grafana 配置文件中，root url 需要相应更新。

查看相关documenttion

这是用于从网络浏览器访问 Grafana 的完整 URL。这 如果您使用 Google 或 GitHub OAuth 身份验证（对于 回调 URL 是正确的）。

注意：如果您有反向代理，此设置也很重要 Grafana 的前面，通过子路径公开它。在这种情况下添加 此 URL 设置末尾的子路径。
