通過 nginx (proxy_pass) 服務 IIS 網站不顯示 CSS、圖像或 js（404 未找到）

我有一個在 Ubuntu 14.04 LTS 上執行的 nginx 反向代理。當向 nginx 代理髮出請求時，它會將請求傳遞給包含一個（預設）網站的 IIS 伺服器。它似乎可以很好地呈現 HTML，但不幸的是，伺服器對所有其他資產都響應 404 錯誤。

這是/etc/nginx/nginx.conf文件：

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
   worker_connections 768;
   # multi_accept on;
}

http {

   ##
   # Basic Settings
   ##

   sendfile off;
   tcp_nopush on;
   tcp_nodelay on;
   keepalive_timeout 65;
   types_hash_max_size 2048;
   # server_tokens off;

   server_names_hash_bucket_size 64;
   # server_name_in_redirect off;

   include /etc/nginx/mime.types;
   default_type application/octet-stream;

   ##
   # Logging Settings
   ##

   access_log /var/log/nginx/access.log;
   error_log /var/log/nginx/error.log;

   ##
   # Gzip Settings
   ##

   gzip on;
   gzip_disable "msie6";

   include /etc/nginx/conf.d/*.conf;
   include /etc/nginx/sites-enabled/*;
}

這是我的defaultnginx 伺服器配置：

server {
   listen 80 default_server;
   listen [::]:80 default_server ipv6only=on;

   index index.php index.html index.htm;

   server_name example.com www.example.com;

   location / {
       try_files $uri $uri/ =404;
       proxy_pass http://104.46.52.226/;
   }

   error_page 404 /404.html;
   error_page 500 502 503 504 /50x.html;
   location = /50x.html {
       root /usr/share/nginx/html;
   }

   location ~ \.php$ {
       try_files $uri =404;
       fastcgi_split_path_info ^(.+\.php)(/.+)$;
       fastcgi_pass unix:/var/run/php5-fpm.sock;
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       include fastcgi_params;
   }
}

以下是對example.comor的請求結果www.example.com（hosts 文件已更改）：

我認為這可能是一個問題，因為我的伺服器配置中沒有root指令 - 但後來我真的不知道從哪裡開始解決這個問題。至少我知道這不是 IIS 伺服器本身的問題，因為我可以完美地瀏覽 localhost。

有什麼想法嗎？首先十分感謝。

編輯：這也是我的錯誤日誌：

最後找到了一個解決方案 - 我強迫 nginx 伺服器嘗試使用try_files $uri $uri/ =404;. 我所要做的就是刪除這條線，它工作得很好:)

location / {
   proxy_pass http://104.46.52.226/;
}

從最不可能的問題開始，80 是正確的埠proxy_pass http://104.46.52.226/嗎？如果不是，這個埠是在監聽哪個埠？如果是 5000，則需要 proxy_pass http://104.46.52.226:5000；這可能不是你的問題。

您需要在位置塊中設置一些標頭，以便 IIS 可以使用它們：

   proxy_set_header  x-real-IP        $remote_addr;
   proxy_set_header  x-forwarded-for  $proxy_add_x_forwarded_for;
   proxy_set_header  host             $http_host;

引用Karl Seguin 的話：

由於 Nginx 實際上是向我們的 Web 伺服器發出請求，因此我們正在向請求中添加標頭，以便 Web 伺服器擁有所有必要的資訊。

他還談到了記憶體。

文件/etc/nginx/sites-enabled/armari.com看起來有一個註釋掉的server {行。這是錯誤之一。所有需要工作的文件都/etc/nginx/sites-enabled/需要讓 Nginx 感覺良好。如果是這個文件，你可能只是沒有粘貼#（註釋開始程式碼）。或者也許你在錯誤發生後改變了它。
