Question:I’m using Apache 2 to host multiple site on a single host using Apache name based VirtualHost feature. However, Apache is displaying lots of warning as follows:

Performing sanity check on apache22 configuration:
[Portal Oct 05 06:59:34 2008] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Portal Oct 05 06:59:34 2008] [warn] _default_ VirtualHost overlap on port 80, the first has precedence

[Portal Oct 05 06:59:36 2008] [warn] NameVirtualHost 81.aaa.www.yyy:80 has no VirtualHosts

How do I fix this warning and host multiple websites under UNIX / Linux Apache 2 webserver?
