Nginx 500 子目录上的内部服务器错误

2024-5-29 • tag-icon

500 Internal Server我只在子目录上遇到错误。

例如，如果我的网站是 example.com，example.com/index.php则可以。

但example.com/phpbb/index.php不起作用。它只是出现一个空白的 php 页面。HTTP
标头显示 HTTP 错误 500 内部服务器错误。

如果我输入example.com/phpbb/index.php/[any-directory]，index.php则会显示根目录。

这一切都很奇怪。我尝试过搜索等，但都无济于事。尝试重新安装 nginx，但没有解决。我确定我的 DNS 配置正确。

更多规格：

Nginx返回一个HTTP 200 OK标题，但发送一个 0kb（空）PHP 文件 -> 我只看到一个空白的屏幕
当我进入子目录时，主网站会加载。例如：如果我进入example.com/blog/，而不是生成404 错误，example.com加载。
Nginx忽略.php子目录中的所有文件。HTML、CSS、JS 运行良好。
没有生成错误日志。即使 php 没有加载，错误日志也是空的。
PHP5-FPM在主网站上运行良好（example.com）
我使用 SSL(链)

答案1

我遇到过这种情况。我所做的就是改变目录。因此，如果您的 public_html 位于 /var/www/example.com 下，它将是这样的：

chown -R www-data:www-data /var/www/example.com

其中 www-data 是 nginx 的用户名和组。

答案2

我不知道为什么索引指令似乎不起作用。

我可以通过将 index.php 添加到 try-file 指令来解决该问题：

try_files   $uri $uri/ $uri/index.php;

我的 Nginx 配置（/sites-available/example.com）

nginx.conf
