如何合併這兩個 nginx 規則以使其正常工作？

在使用 htaccess 規則之前我執行的是 Apache，但切換到 nginx 運行 Discourse 論壇軟體的 docker 實例。我在 docker 實例之外運行 nginx，然後使用 proxypass 使其位於 domain.com/forum 中。在我進行如下設定之前，為了將輸入的任何子網域減去 www.並將其附加到 url 的末尾。如果沒有提供子網域，它將正常工作。

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteCond %{HTTP_HOST} .example.com$ [NC]
RewriteRule ^(.*)$ http://example.com/forum/t/%1$1 [L,NC,QSA]

我使用了從 htaccess 到 nginx 的轉換器，它給了我這個：

location / {
  if ($http_host !~ "^www\."){
   rewrite ^(.*)$ http://example.com/forum/t/%1$1 redirect;
  }
}

我目前的位置設定如下所示：

location /forum {
    proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
    proxy_set_header Host $http_host;
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto https;
   }
    fastcgi_read_timeout 60;
 }

所以我的問題是，如何將 if 語句中轉換後的程式碼與包含 proxy_pass 內容的目前程式碼合併？我試著把它放在那裡，但最後卻出現了一個循環。

任何見解將不勝感激，謝謝！

這就是我最終得到的效果。我事後為特定的子網域添加了一些額外的東西，但這才是真正起作用的原因。

 server {
    server_name example.com www.example.com;
    listen ipaddress;

    root /home/me/public_html;
    index index.html index.htm index.php;
    access_log /var/log/virtualmin/example.com_access_log;
    error_log /var/log/virtualmin/example.com_error_log;
    fastcgi_param GATEWAY_INTERFACE CGI/1.1;
    fastcgi_param SERVER_SOFTWARE nginx;
    fastcgi_param QUERY_STRING $query_string;
    fastcgi_param REQUEST_METHOD $request_method;
    fastcgi_param CONTENT_TYPE $content_type;
    fastcgi_param CONTENT_LENGTH $content_length;
    fastcgi_param SCRIPT_FILENAME /home/me/public_html$fastcgi_script_name;
    fastcgi_param SCRIPT_NAME $fastcgi_script_name;
    fastcgi_param REQUEST_URI $request_uri;
    fastcgi_param DOCUMENT_URI $document_uri;
    fastcgi_param DOCUMENT_ROOT /home/me/public_html;
    fastcgi_param SERVER_PROTOCOL $server_protocol;
    fastcgi_param REMOTE_ADDR $remote_addr;
    fastcgi_param REMOTE_PORT $remote_port;
    fastcgi_param SERVER_ADDR $server_addr;
    fastcgi_param SERVER_PORT $server_port;
    fastcgi_param SERVER_NAME $server_name;
    fastcgi_param HTTPS $https;
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/php-nginx/15187383894597.sock/socket;
    }
    listen 443 ssl http2;  listen [::]:443 ssl http2;
    ssl_certificate /home/me/ssl.combined;
    ssl_certificate_key /home/me/ssl.key;
        http2_idle_timeout 5m; # up from 3m default

    location /forum {

        proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
        proxy_set_header Host $http_host;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
    }
    fastcgi_read_timeout 60;
}

 # This server forwards requests from subdomains
 server {
  server_name ~^(.*)\.example\.com$;
   listen   ipaddress default_server;

  location / {
    return 301 https://example.com/forum/c/$1;
  }
}

然後我添加了其中的一些來測試隨機的特定的，它們工作得很好。

 # Test for specificsub
 server {
  server_name specificsub.example.com;
   listen   ipaddress;

  location / {
    return 301 https://example.com/forum/c/assets/specificsub;
  }
}

 # Test for specificsub2
 server {
  server_name specificsub2.example.com;
   listen   ipaddress;

  location / {
    return 301 https://example.com/forum/c/assets/specificsub2;
  }
}

像這樣的東西應該​​可以完成工作。這可能不會完全按照原樣工作，但應該為您提供一個發展自己的整體策略。如果您希望有人為您完成所有這些工作並進行測試，您應該聘請顧問。

我假設您有無限的子域集。

// This server serves only forum traffic on the main domain
server {
  server_name example.com;

  location /forum {
      proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
      proxy_set_header Host $http_host;
      // etc
   }

   // This should forward all requests to the forum subfolder
   location / {
     return 301 http://example.com/forum/;
   }

   // Insert any other required locations
 }

 // This server forwards requests from subdomains
 server {
  server_name ~^(.*)\.example\.com$;
  // If the line above doesn't work uncomment these two and try them instead. They basically listen to everything not specified explicitly.
  // listen       80  default_server;
  // server_name  _;

  location / {
    return 301 http://example.com/forum/t/$1;
  }
}
