cgi-bin 没有被 nginx 代理用于 nagios 主机

cgi-bin 没有被 nginx 代理用于 nagios 主机

我在 ubuntu 20.04 虚拟机上设置了反向代理 nginx 主机 -> nagios，它们就像默认的 apt-get 安装一样，没有自定义。我添加了自签名证书只是为了测试。

192.168.254.107-nginx 192.168.254.200-nagios

问题是 cgi-bin 似乎没有重定向，并且由 nginx 本身提供服务

Nginx 配置

server {
    listen 443 ssl;
    listen 80 default_server;
    ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
    ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout 2m;

    location /nagios4 {
        proxy_pass https://192.168.254.200/nagios4;
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
    }
}

错误

我注意到当我尝试在另一个浏览器中打开时它会去寻找 nginx 主机上的路径......

https://192.168.254.107/cgi-bin/nagios4/status.cgi?hostgroup=all&style=hostdetail

问题可能出在你的配置中的这两行：

location /nagios4 {
    proxy_pass https://192.168.254.200/nagios4;

删除指令nagios4中location转发所有位置到代理的 或从指令中
删除。 您可以从错误日志中看到目录和实际 cgi 文件之间出现的类似。/nagios4proxy_pass
nagios4cgi-binextinfo.cgi

我发现了同样的问题，虽然它很老了，但仍然适用于 HTTP。我没有尝试过 https，因为我使用的是自签名证书

主要问题是 cgi-bin 仍在 nginx 文件夹/主机上调用，而不是在后端。这解决了该问题并将调用重定向到后端。

     location /cgi-bin/nagios3/ {
          proxy_pass https://nagios.localdomain.com/cgi-bin/nagios3/;
          proxy_redirect default;
     }

     location /nagios3/ {
          proxy_pass  https://nagios.localdomain.com/nagios3/;
          proxy_redirect default;
     }

     location /nagios/ {
          proxy_pass  https://nagios.localdomain.com/nagios3/;
          proxy_redirect default;
     }
