Symfony2 应用程序的空白页面

Question

在设置 Web 环境（Apache2、MySQL、PHP7）后，我刚刚在 AWS 账户（使用 Ubuntu 16.04 的 EC2 实例上）部署了我的基于 Symfony2 的应用程序。 Ubuntu /var/www/html/index.html 默认文件正确呈现。但是当谈到 Symfony2 时，我的 app.php 和 app_dev.php 都有一个空白页面。当我使用 Filezilla 调试工具进行测试时，我可以看到出现“500 Internal Server Error”错误消息。 Symfony2 config.php 表明现在一切都很好，我只需在 php.ini 上添加 date.timezone 值。我的 .htaccess 文件配置良好，因为我使用的模型与我之前设置的其他基于 Symfony2 的网站上工作的模型相同。

这是我在 /logs/dev.log 上的内容：

关于如何使用这些信息来解决我的问题的任何线索，尤其是在日志上？

Answer 1

我已经能够通过在开发环境中运行 app/console assets:install 和清除缓存 (app/console cache:clear) 来解决此问题。然后，我不得不处理以下异常：

ClassCollectionLoader.php 第 239 行中的 RuntimeException：无法写入缓存文件“/var/www/html/app/cache/dev/classes.php”。

我按照此处提供的说明进行保留：http://symfony.com/doc/2.7/setup/file_permissions.html

对于 Linux 系统：

$ rm -rf app/cache/*
$ rm -rf app/logs/*    

$ HTTPDUSER=`ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|

[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
# if this doesn't work, try adding `-n` option
$ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
$ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
