我使用 django 与 apache 和 mod_wsgi
当我在 apache 配置文件 (.conf) 中使用 WSGIApplicationGroup %{GLOBAL} 时，我遇到问题。我不知道我是否正确使用了这个指令，或者我需要以其他方式使用它，问题是我需要添加这个指令来解决 xapian 的问题，如这张票中所述（http://trac.xapian.org/ticket/185）之后搜索开始工作，但我的所有网站内容都混合在一起，这意味着 site1 内容出现在 site2 上。当我删除 WSGIApplicationGroup %{GLOBAL} 时，网站再次正确呈现，但搜索停止工作。
这是我的 .conf 文件内容：

WSGIApplicationGroup %{GLOBAL}

有人遇到过这个问题吗
有什么建议
thanks
Django 的实现阻止多个 Django 实例在同一解释器（应用程序组）中运行。因此，如果在同一 Apache 服务器上运行多个 Django 站点并且必须将 WSGIApplicationGroup 设置为 %{GLOBAL}，那么您必须使用守护进程模式并将每个 Django 站点委托给单独的守护进程进程组。无论如何，守护进程模式是首选。
确保您阅读：
http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide
http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode
后者解释了为什么守护进程模式在使代码重新加载更容易方面是好的。
