Apache: [warn] _default_ VirtualHost overlap on port 80, the first has precedence Error and Solution

last updated November 2, 2008 in Apache, CentOS, Debian / Ubuntu, Fedora Linux, FreeBSD, Linux, Networking, RedHat and Friends, Solaris-Unix, Suse, Troubleshooting, Ubuntu Linux, UNIX

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:

Sample Apache 2 Virtual hosting configuration

If you want to maintain multiple domains/hostnames on your machine you can setup VirtualHost containers for them. Most configurations use only name-based virtual hosts so the server doesn’t need to worry about IP addresses. This is indicated by the asterisks in the directives below.

# My Virtual Hosts Config File for Two Domains
NameVirtualHost *:80
 
<VirtualHost *:80>
    ServerAdmin webmaster@theos.in
    DocumentRoot "/usr/local/docs/theos.in"
    ServerName www.theos.in
    ServerAlias theos.in
    ErrorLog "/var/log/theos.in-error_log"
    CustomLog "/var/log/theos.in-access_log" common
</VirtualHost>
 
<VirtualHost *:80>
    ServerAdmin webmaster@nixcraft.com
    DocumentRoot "/usr/local/docs/nixcraft.com"
    ServerName www.nixcraft.com
    ServerAlias nixcraft.com
    ErrorLog "/var/log/nixcraft.com-error_log"
    CustomLog "/var/log/nixcraft.com-access_log" common
</VirtualHost>

The NameVirtualHost *:80 directive should go in your httpd.conf – sites available is generally symlinks of the actual virtual hosts.

When I configure the same file , I have a problem. I used Firefox, everytime I type http://www.theos.in or http://www.nixcraft.com, I only see mainpage (theos.in), no nixcraft.com

Finally it fixed.

I’ve had this problem on an Ubuntu Server for the whole time I’ve been running it (about 18 months) and have just avoided using Apache on it since I couldn’t find a fix and it seemed to work fine everywhere else. Now its fixed and I can use it properly.

My eternal gratitude!!!!

If you use Ubutu 10.10 as server and have configured as they suppose
For example:
under apache2/sites-enabled/eww.test.de
with the content:
# —————–
# eww.test.de
# ——————————————————-

ServerName eww.test.de
ServerAlias eww.test.de
ServerAdmin admin@localhost
ErrorLog /var/log/httpd/test-error_log
CustomLog /var/log/httpd/test-access_log common
DocumentRoot /home/eww/local

…

and edit your /etc/apache2/apache2.conf to add “NameVirtualHost *:80”
beware that you don’t add this at the end of the file instead put it over
>Include httpd.conf< or add this directive in the httpd.conf.
It took some hours of "service apache2 restart" until I found it.

If you find yourself really stuck with this error, make sure that ALL of your VirtualHosts’ port designators match the port designated on the NameVirtualHost directive!

For instance:
```
NameVirtualHost *:80

    # Some Apache Directives
```
That will result in the Port Overlap error because your VHost port doesn’t match the NameVirtualHost port.

Oops, that last should have been:

NameVirtualHost *:80

<VirtualHost *>
    # Some Apache Directives
</VirtualHost >

Thanks for this info. I couldn’t figure out why my virtual host config was not working. The Apache error message is not very useful for this problem.

Thanks guy.

Andres says:

Also remember, at least on Red-hat based distors, that all the site configurations are loaded from /etc/httpd/conf.d in alphabetical order making the first one the default virtual host.

Cheers..!!
You have resolve my problem.

For all of you who got problem.

This line : NameVirtualHost *:80 MUST be just before :

    ServerAdmin webmaster@theos.in
    DocumentRoot "/usr/local/docs/theos.in"
    ServerName www.theos.in
    ServerAlias theos.in
    ErrorLog "/var/log/theos.in-error_log"
    CustomLog "/var/log/theos.in-access_log" common

 

    ServerAdmin webmaster@nixcraft.com
    DocumentRoot "/usr/local/docs/nixcraft.com"
    ServerName www.nixcraft.com
    ServerAlias nixcraft.com
    ErrorLog "/var/log/nixcraft.com-error_log"
    CustomLog "/var/log/nixcraft.com-access_log" common

Thx for this tweak !
