你的ServerName / ServerAlias指令错误。ServerName应该是主机名。你可能应该删除ServerAlias。
然后只需执行明显且重复的VirtualHost / Listen指令，只需更改文件系统中脚本的端口号和位置即可。
最后，不要将documentRoot设置为你的Django代码所在的位置，因为如果你填充Apache配置，它很容易意外地暴露你的源代码以供下载。因此，只需从VirtualHost for Django网站删除documentRoot指令即可。
Listen 80<VirtualHost *:80>ServerName www.example.comWSGIscriptAlias / /opt/django/site1/apache/django.wsgiAlias /media /opt/django/site1/media/staticsAlias /admin_media /home/myuser/Django-1.1/django/contrib/admin/media<Directory opt/django/site1/apache>Order allow,denyAllow from all</Directory><Directory /home/myuser/Django-1.1/django/contrib/admin/media>Order allow,denyAllow from all</Directory></VirtualHost>Listen 8080<VirtualHost *:8080>ServerName www.example.comWSGIscriptAlias / /opt/django/site2/apache/django.wsgiAlias /media /opt/django/site2/media/staticsAlias /admin_media /home/myuser/Django-1.1/django/contrib/admin/media<Directory opt/django/site2/apache>Order allow,denyAllow from all</Directory><Directory /home/myuser/Django-1.1/django/contrib/admin/media>Order allow,denyAllow from all</Directory></VirtualHost>Listen 8090<VirtualHost *:8090>ServerName www.example.comWSGIscriptAlias / /opt/django/site3/apache/django.wsgiAlias /media /opt/django/site3/media/staticsAlias /admin_media /home/myuser/Django-1.1/django/contrib/admin/media<Directory opt/django/site3/apache>Order allow,denyAllow from all</Directory><Directory /home/myuser/Django-1.1/django/contrib/admin/media>Order allow,denyAllow from all</Directory></VirtualHost>
我还添加了缺少的Directory指令，以允许访问静态文件。但是，你应该查看路径。
