昨天我在 CentOS 5.7 上安装了单声道版本 2.11.1。从那以后，我无法让我的 .NET4.0 应用程序通过 mod_mono 和 Apache 工作，但我的 .NET2.0 应用程序工作正常。从命令行运行 .NET4.0 控制台应用程序也可以正常工作。

使用的版本：

  • 单声道 2.11.1
  • mod_mono 2.10
  • xsp 2.10.2
  • 阿帕奇 2.2.21

我的 Apache 配置（相关部分）：

Alias /testproject "/var/www/sites/testproject"

MonoServerPath testproject "/usr/bin/mod-mono-server4"
MonoAutoApplication disabled
MonoDebug testproject true
MonoSetEnv testproject MONO_IOMAP=all
MonoApplications testproject "/testproject:/var/www/sites/testproject"

<Location /testproject>
        SetHandler mono
        MonoSetServerAlias testproject
</Location>

Apache 错误日志中出现以下异常：

mod-mono-server4
Listening on: /tmp/mod_mono_server_testproject

这看起来像是 Mono、mod_mono、xsp 中的错误，还是完全不同？

尝试将带有以下标志的 XSP 运行到 mono 可执行文件：

--debug=casts

（从这里：http ://tirania.org/blog/archive/2008/Apr-16-1.html ）

您可能已经安装了一个脚本来在您的系统中运行 XSP。在我这里是 /usr/bin/xsp4。通过查看它，您会发现您需要在 MONO_OPTIONS 环境变量中包含此标志，或者只需修改该文件以添加它。
