nginx 無法綁定到埠 80.. 埠 80 上沒有執行

我正在嘗試在 Ubuntu 11.04 上設置 nginx。我大致遵循了此處的說明：http: //library.linode.com/frameworks/sinatra/debian-6-squeeze。我知道它適用於 Debian，但我基本上採取了這些步驟，然後在 google 上搜尋“如何在 ubuntu 11.04 中執行 x”雖然，我確實從他們的庫中提取了 init 腳本。

Starting nginx: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

命令：‘sudo lsof -i:80’ 不會返回在埠 80 上執行的任何內容。

我該如何解決這個問題或任何關於可能出錯的想法？

我在全新的 Ubuntu 安裝上看到Nginx + uWSGI - 綁定錯誤埠 80並嘗試重新啟動電腦並執行一次，我得到了同樣的錯誤。執行一次後，我執行 lsof 命令。

一種可能性是，由於某種原因，nginx 兩次綁定到埠 80。

如果它試圖這樣做，它將失敗。一個範例可能是綁定到 IPV6 和 IPV4，或者將其綁定到公共 ip 和萬用字元 ip。

檢查您的 nginx 配置以確保它只綁定一次。

嘗試：

http{

   server {

       listen 80;
       listen localhost;  # <- probably will fix your problem

       location / {
       root /data/www;
       }

       location /images/ {
       root /data;
       }
   }
}
