Php 为什么我将应用程序上载到服务器时出现服务器错误500

我刚刚将应用程序部署到服务器上。我压缩了我的整个应用程序文件夹，并将其上传到我的服务器。我还导出了我的应用程序的数据库表，并将其导入到我的服务器phpmyadmin。我已经配置了

.env

设置，但当我尝试访问我的应用程序时，它会抛出服务器错误500。我的应用程序位于

mywebsite.com/app/

所有文件都位于应用程序文件夹中。我还试图将公共文件移动到

public\u html

，但仍然无法工作

看起来您使用的是PHP<5.5。Laravel 5.2需要PHP5.5.9版本，查看index.PHP的第50行有：

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

并添加到PHP5.5中

因此，您应该验证您的PHP版本。可能是5.4或更早

这可能是许多事情之一。如果PHP版本不同，可能是语法错误，有许多服务器设置可能会产生这种影响，可能Apache缺少mod_rewrite。查看错误日志会给您一个好主意。检查日志文件。这将为您和我们提供一些线索。500是一个一般的服务器错误，可能意味着如上所述的大量问题。检查服务器日志，读取错误，更改服务器配置以将错误公开给客户端（调试模式打开）。添加的日志请检查@tanaydindon't upload public folder。只要上传它的内容，你就可以用一个只包含
