在apache配置中使用WSGIApplicationGroup%{GLOBAL}的问题

Question

即时通讯使用django与apache和mod_wsgi我在apache配置文件(.conf)中使用WSGIApplicationGroup%{GLOBAL}时遇到问题.我不知道我是否正确使用此指令或我需要以另一种方式使用它,问题是我需要添加此指令来修复此票证中描述的xapian问题(http://trac.xapian. org/ticket/185)之后搜索开始起作用,但我的所有网站内容都混淆了,这意味着site1内容出现在site2上.当我删除了WSGIApplicationGroup%{GLOBAL}时,网站再次正常呈现,但搜索停止了工作.

这是我的.conf文件内容:

NameVirtualHost my_ip_address:80
WSGIApplicationGroup %{GLOBAL}
<VirtualHost my_ip_address:80>
ServerName www.site1.com
ServerAlias site1

WSGIScriptAlias / "/home/sa/www/site1/apache/django.wsgi"
<Directory "/home/sa/www/site1/apache">
    Allow from all
</Directory>

Alias /site_media/ "/home/sa/www/site1/media/"
<Directory "/home/sa/www/site1/media/">
    Order allow,deny
    Options Indexes FollowSymLinks

任何人都面临这个问题的任何建议

Django的实现防止多个Django实例在同一个解释器(应用程序组)中运行.因此,如果在同一个Apache服务器上运行多个Django站点并且必须将WSGIApplicationGroup设置为%{GLOBAL},则必须使用守护程序模式并将每个Django站点委派给单独的守护程序进程组.无论如何,守护进程模式是首选.

确保您阅读:

后者解释了为什么守护进程模式很好,以使代码重新加载更容易.
