nginx php文件自動下載而不是在http上執行並且在https上找不到404

問題 1：我嘗試使用 http 在 ip 本地地址下訪問我的網站，每次我訪問它時，它都會下載 php 文件，意思是不執行。問題 2：我嘗試使用 https 訪問我的域下的站點，但它返回結果 ‘404 Not Found’

下面是我的 nginx 配置：

# This file will automatically load configuration files provided by other

任何人都可以幫助我的配置嗎？

• 我託管的文件放在 /var/www/html/nextcloud 中。
• 對於 php 我使用 php8.1-fpm
• 對於 nginx 我使用版本 nginx/1.18.0
• 我的作業系統是debian
• 我託管的文件是 Nextcloud Database Mariadb

問題是由這部分引起的：

location / {
   rewrite ^ /index.php$uri;
   try_files $uri $uri/ ?404;
}

這使得 nginx 會/index.php/在您訪問/網站時以及/index.php/test訪問網站時進行查找/test。

.php您的 PHP 位置僅匹配以( \.php$regex)結尾的文件。因此請求不會傳遞給 PHP 解釋器。

如何實際修復它取決於您的應用程序希望接收請求的確切程度。例如，使用 Wordpress 只需將所有請求傳遞給index.php它並處理其餘的 URL 解析：

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

您的 HTTPS 配置的問題是您server_name不包含您的域名。因此 nginx 使用預設的虛擬主機進行請求。

您的 HTTPS 配置也缺少ssl_certificate和ssl_certificate_key指令。
