Apache VirtualHost CentOS



To host multiple sites on the same server, VirtualHost entries can be used
in Apache to route the Web traffic to the proper files.

In this tutorial, we'll assume that the domain we are trying to add is
named "example.com". You'll want to replace "example.com" with the name of
the domain that you are actually configuring as you run the steps.

First, a new directory for the domain should be created. It is recommended
to create separate directories per domain under the main /var/www/ document
root. That way, the files for sites won't reside under one another and
potentially interfere with the settings for other sites. For this example,
we'll create a sub-directory with the same name as the domain (the name can
be anything you like so long as the Apache configuration is set the same).
The directory should also be changed to the username that you wish to
administer it as, we'll be using "centos" as the username:

sudo mkdir /var/www/example.com/

sudo chown centos /var/www/example.com/

We'll now place a file in that directory to use for testing later:

echo "Hello world from example.com" > /var/www/example.com/index.html

We can now proceed with adding the VirtualHost entry into Apache to
associate the example.com name with the content above. To do so, create a
file at:


In that file, place the following:

<VirtualHost *:80>

ServerName www.example.com
ServerAlias example.com

ServerAdmin user@example.com

DocumentRoot /var/www/example.com/


Using both the ServerName and ServerAlias lines will allow the server to
respond to requests for either http://example.com or
http://www.example.com. The ServerAdmin line should have the email
address entered that you wish to use for the default Webmaster address for
the domain.

Apache now needs to be restarted to update to the new configuration. That
can be done with:

sudo service httpd reload

The new domain can now be tested in your browser. Going to
http://www.example.com should load the "Hello world from example.com"
message entered into the index.html file earlier.
