在設置Web環境（Apache2，MySQL，PHP7）後，我剛剛在AWS賬戶（在使用Ubuntu 16.04的EC2實例上）部署了基於Symfony2的應用程序。 Ubuntu /var/www/html/index.html默認文件被正確渲染。但是當談到Symfony2時，我的app.php和app_dev.php都有一個空白頁面。當我使用Filezilla調試工具進行測試時，可以看到出現「500 Internal Server Error」錯誤消息。 Symfony2 config.php表明現在一切正常，我只需要在php.ini中添加date.timezone值即可。我的.htaccess文件配置得很好，因爲我使用的是與之前設置的其他基於Symfony2的網站相同的模型。使用Symfony2應用程序的空白頁
這是我對/logs/dev.log：
