【问题描述】：
首先，我对所有这些东西都很陌生。
我使用装有 Visual Studio 2013 Ultimate 的 Windows 机器作为开发环境，并希望在使用 Apache/mod_mono 的 Linux 机器上托管创建的 Web 应用程序。
Linux机器运行：
- CentOS 6.5 版（最终版）
- Apache/2.2.15 (Unix) with mod_mono
- Mono JIT 编译器版本 3.10.0（tarball，2014 年 10 月 4 日星期六 16:22:21 UTC）
我目前在 Linux 机器上托管 2 个 ASP.NET 应用程序：
- monotest：使用 MonoDevelop 模板创建的 MVC 项目，主要用于测试 apache 配置。此应用程序运行良好（即使重启 apache 时日志抛出错误）
- webappexample：一个 MVC3 项目，带有 razor 视图和使用 Visual Studio 模板创建的 MySQL 数据库。该网站给出“500 内部服务器错误”。
当我重新启动 Apache 时，此输出会打印在 error_log 中：

经过一番谷歌搜索，我发现了很多关于复制某些 DLL 的博客文章。我已经忘记了到目前为止我尝试过的内容，但还没有解决我的问题。我也试过用单声道编译器编译 webappexample，编译时没有任何警告/错误，但仍然不能解决我的问题。
谁能在这里提供一些见解或解决方案？
