If you are getting the warning “_default_ VirtualHost overlap on port 80, the first has precedence” you are missing the NameVirtualHost directive in your Apache configs.
Adding either of the following will alleviate the problem:
NameVirtualHost 127.0.0.1:80
or
NameVirtualHost *:80
Where 127.0.0.1 is the server’s IP address.
