I think that the question title pretty much says the problem. I'm getting these two errors when I restart httpd:

[Wed Jun 22 13:39:23 2011] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Wed Jun 22 13:39:23 2011] [warn] NameVirtualHost *:80 has no VirtualHosts

I am including a file which has this as the only line:

NameVirtualHost *:80

And both of the VirtualHosts are almost identical to this:

<VirtualHost *:80>
        ServerAdmin webmaster@<other-name>.com

        DocumentRoot /var/www
        ServerName www.<name>.com
        ServerAlias <name>.com *.<name>.com
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>

        ErrorLog /var/log/httpd/error_log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog /var/log/httpd/access_log combined

</VirtualHost>

Clearly, I am missing something obvious which effects this outcome, but I don't know what. (Obviously, both sites are currently directing to the same page)

(Not certain if this matters, but I ma using CentOS).

SOLUTION

Totally appreciated Mike Diehn's solution below, but it is slightly different solution than he suggested.

I ran:

/usr/sbin/httpd -t -D DUMP_VHOSTS

And I got

[Wed Jun 22 14:23:20 2011] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Wed Jun 22 14:23:20 2011] [warn] NameVirtualHost *:80 has no VirtualHosts
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
_default_:443          <name-one>.com (/etc/httpd/conf.d/ssl.conf:81)
*:80                   www.<name-one>.com (/etc/httpd/conf/sites-enabled/100-default:1)
*:80                   www.<name-two>.info (/etc/httpd/conf/sites-enabled/200-info:1)
*:*                    www.<!!!!!!!!!!!!!!>.com (/etc/httpd/conf/sites-enabled/6-<bad>.com:1)
Syntax OK

Notice the !!!!!!!!!!!? That was there because I accidentally copied it from somewhere else. It gobbled up everything and made it not work.

I'm curious as to what most people's views are on this subject. Personally, I will almost always prefer symlinks unless I have no other option -- I find that it is far more obvious when someone is navigating the file system, but, on the other hand aliasing is more platform independent. Windows XP, for example, doesn't have anything remotely comparable to symlinks (NTFS junctions are not interpreted correctly by at least some environments), which means that anything which relies on symlinks in a *nix based system cannot be transferred. (I know that Windows 64x OS's have symlinks, but I've not seen if they can be read correctly by the environments previously mentioned)

In addition to this, I was also wondering which is considered faster. Is this even possible to know? Do you have a conjecture? I would imagine that since symlinks are generally more low-level than Apache it would make sense that they would be referenced faster, but, on the other hand, I would guess that Apache is required to do a lookup in either case so it would be disk read dependent.

I am BRAND NEW to Glassfish, so I thought I would install a copy and poke around (I'm actually looking at a number of Java servers for personal edification). So, I installed a basic copy of Glassfish 3 on Ubuntu 10 and java-6-openjdk.

My first run through, I tried using sudo ./glassfish-3.0.1-unix.sh. Unfortunately, when I called ./asadmin start-domain and then navigated to the admin panel (at the default location), I found only this (there is more HTML on the page, but this is the only text. I can provide the entire HTML doc if needed.):

<div id="copyright" style="width: 720px; margin-left: auto; margin-right: auto; padding: 5px;"> 
        <span>Copyright © 2005, 2010, Oracle and/or its affiliates. All rights reserved.  U.S. Government Rights - Commercial software.

    </div> 

Also, the form with the ID "loginButton" is clearly missing from the HTML.

So, I uninstalled that version of Glassfish and installed using sudo ./glassfish-3.0.1-web-unix.sh. This had the same error. Finally, I tried installing it without using sudo, but I ran into the same error.

How do I get the stupid admin page working?
