NGINX 埠代理不工作

我正在努力做到這一點，而不是輸入“www.example.com:8080”，而是輸入“www.example.com”。我正在使用 NGINX，但我似乎無法讓它工作。我在網上找到了許多有用的文章，他們都說要做我嘗試過但不起作用的相同事情。

我在 ubuntu apache2 伺服器上執行

這是我所做的：

1. sudo 進入位於 /etc/nginx/site-enabled/default 的配置文件
2. 上面寫著聽 80 的地方，把它改成聽 8080
3. sudo 服務 nginx 重啟

但是，這似乎沒有任何效果。

我對上面的預設配置文件進行了以下編輯並重新啟動，但它似乎仍然不起作用

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

       root /usr/share/nginx/html;
       index index.html index.htm;

       # Make site accessible from http://localhost/
       server_name localhost;

       location / {
               proxy_pass 127.0.0.1:8080;
               # First attempt to serve request as file, then
               # as directory, then fall back to displaying a 404.
               # try_files $uri $uri/ =404;
               # Uncomment to enable naxsi on this location
               # include /etc/nginx/naxsi.rules
       }
....
}

—已解決的問題—

我的配置文件沒有任何問題。當我查閱 /var/log/nginx/error.log 時，我看到了錯誤

[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

所以我執行了以下命令：

sudo fuser -k 80/tcp
service nginx start

一切正常：）

你把它倒過來了。

埠 80 是預設的 HTTP 埠，因此鍵入www.example.com與鍵入相同www.example.com:80

將您的 listen 指令改回listen 80;，確保您以 root 身份啟動 nginx 並且該埠沒有在防火牆中被阻止，您應該很好。

如果您的後端應用程序已經在偵聽埠 8080，您想告訴 nginx 將請求路由到該地址。

location / {
   proxy_pass http://127.0.0.1:8080;
}

這樣，當請求從 80 埠進入時，nginx 會將其發送到埠 8080 上的應用程序，該應用程序會將響應返回給 nginx - 然後將其返回給從未在任何地方看到埠 8080 的使用者。
