Nginx作为虚拟主机和反向代理

问题描述

我在ubuntu服务器上运行了GlassFish（一个Java应用程序服务器）。我也有在其他端口上运行的PHPpgadmin，比如说5555，并配置了apache。

我将Nginx用作GlassFish前面的反向代理。 （尚未设置端口443的SSL和配置。）

server {
  listen          80;
  server_name     my_domain;

  location / {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://my_ip_number:8080;
  }
  
  location /PHPpgadmin {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  
        proxy_pass http://my_ip_number:5555/PHPpgadmin;
  }  
}

当我尝试通过在/etc/Nginx/conf.d/中设置以下文件来为PostfixAdmin创建虚拟主机（如here所述）时。在http://postfixadmin.my_domain/setup.PHP中，我只看到了玻璃鱼的404页。
设置了子域的DNS A记录。
我的配置有什么问题？该如何解决？

预先感谢

server {
   listen 80;
   listen [::]:80;
   server_name postfixadmin.my_domain;

   root /usr/share/postfixadmin/public/;
   index index.PHP index.html;

   access_log /var/log/Nginx/postfixadmin_access.log;
   error_log /var/log/Nginx/postfixadmin_error.log;

   location / {
       try_files $uri $uri/ /index.PHP;
   }

   location ~ ^/(.+\.PHP)$ {
        try_files $uri =404;
        fastcgi_pass unix:/run/PHP/PHP7.4-fpm.sock;
        fastcgi_index index.PHP;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/Nginx/fastcgi_params;
   }
}

解决方法

我意识到服务器的设置方式，无法实现我上面试图做的事情。无需为PostfixAdmin创建虚拟主机！

这是我的最终配置，一切正常。

server {
  listen          my_ip_number:80;
  server_name     example.com www.example.com;

  include snippets/letsencrypt.conf;
  return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name www.example.com;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;
    include snippets/ssl.conf;
    include snippets/letsencrypt.conf;

    return 301 https://example.com$request_uri;
}


server {
    listen 443 ssl http2;

    server_name example.com;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;
    include snippets/ssl.conf;
    include snippets/letsencrypt.conf;

    access_log  /var/log/nginx/example.com.access.log; # upstreamlog;
    error_log   /var/log/nginx/example.com.error.log;
    rewrite_log on;

  location / {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header HTTPS "on";

        proxy_pass http://my_ip_number:8080;
  }

  location /phppgadmin {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_pass http://my_ip_number:5555/phppgadmin;
  }


  location /mypostfixadmin {
        proxy_pass http://my_ip_number:5555/postfixadmin;

        proxy_set_header Host $http_host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;

        client_max_body_size 0;
  }
