在Apache / mod_mono上使用MySQL部署ASP.NET MVC Internet应用程序

Question

首先，我对所有这些东西都很陌生。

我将Windows机器与Visual Studio 2013 Ultimate一起用作开发环境，并希望使用Apache / mod_mono将创建的Web应用程序托管在Linux机器上。

Linux机器运行：

• CentOS版本6.5（最终版）
• 带有mod_mono的Apache / 2.2.15（Unix）
• Mono JIT编译器版本3.10.0（2014年10月4日星期六UTC tarball）

我目前在Linux机器上托管2个ASP.NET应用程序：

1. monotest ：使用MonoDevelop模板创建的MVC项目，主要用于测试apache配置。 此应用程序运行正常（即使重新启动apache时日志抛出错误）
2. webappexample ：一个带有剃刀视图和使用Visual Studio模板创建的MySQL数据库的MVC3项目。 该网站给出“ 500内部服务器错误”。

当我重新启动Apache时，此输出将打印在error_log中：

经过一番谷歌搜索后，我遇到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已经尝试过的东西，但是还没有解决我的问题的方法。 我也尝试过使用mono编译器编译webappexample，该编译没有任何警告/错误，但仍然不能解决我的问题。

任何人都可以在这里提供一些见解或解决方案吗？

Answer 1

您是否在Linux框中检查过mod_mono的配置？ 也许mond_mono被配置为使用aspnet v2框架（.net v2，v3，v3.5），也许您的应用需要v4框架（.net v4，v4.5）

我现在无法访问linux机器，但我相信conf文件位于/mods-available/mod-mono.conf下。该文件应具有对mod-mono的版本2或4的引用。

我认为您还应该检查apache站点/sites-available/.conf的配置，我相信此conf文件还包含一些mod_mono引用，这些引用应指向正确的版本。
