This is the easiest thing in the world to do. That said, it's one of the most commonly asked questions on Linux web forums.
In /etc/httpd/conf/httpd.conf scroll to the bottom and find the line that says
#NameVirtualHost *:80
Un-hash it, and then add your virtual host(s) below it. Multiple hosts? Create a new entry for each virtual host.
<VirtualHost *:80>
ServerName linux-101.org
ServerAlias *.linux-101.org
DocumentRoot /data/web/linux-101.org/public_html
ServerAdmin hostmaster@nospam.uplinkzero.com
ErrorLog logs/linux-101.org_error.log
CustomLog logs/linux-101.org_access.log combined
<Directory "/var/www/linux-101/public_html">

Order allow,deny

</VirtualHost>People who are using SELinux policies should check the permissions on their document root. The default will work.
