【问题描述】：

我刚刚将我的应用程序部署到我的服务器。我压缩了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，但是当我尝试访问我的应用程序时，它会引发服务器错误 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。我也尝试将公共文件移动到public_html，但仍然无法正常工作。

.env 文件：

APP_ENV=local
APP_DEBUG=true
APP_KEY=base64:keyofmyapp
APP_URL=http://mywebsite.com

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=dbname
DB_USERNAME=username
DB_PASSWORD='password'

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null

【问题讨论】：

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。查看错误日志应该会给您一个好主意。
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，阅读错误，更改服务器配置以将错误暴露给客户端（调试模式开启）。

【解决方案1】：

看来您使用的是 PHP

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

并且class name resolution 是在 PHP 5.5 中添加的。
