Was the text copied and pasted in? Or typed? There's an interesting
item in the error messages:


> apache2: Could not reliably determine the server's fully qualified domain
> name, using 127.0.1.1 for ServerName
> [Fri Jun 01 00:51:20 2012] [warn] NameVirtualHost 127.0.0.1:0 has no
> VirtualHosts


The first error message says 127.0.1.1 the second says 127.0.0.1.
If you copied and pasted, I'd check the hosts file for a typo.
