What is Apache2 VirtualHost?

Apache2 VirtualHost is use for multidomain purpose. We need to configure 2 VirtualHost name to each domain, so we can see a different website from each domain.

First I assume we have installed apache2 webserver and it's running smootly in Ubuntu Server.

To configure apache webserver VirtualHost in Ubuntu server is different from other linux OS like fedora/redhat/centos. In Ubuntu apache2 have separated the virtual host into sites-available and sited-enabled directory.

Example we have domain inferno.web.id

We need to login into the server and have a root user previleges.
We also need to create a file name inferno.web.id in sites-available directory

Change directory to /etc/apache2/sites-available/

Add NameVirtualHost into Default site

root@athena:/etc/apache2/sites-available#pico default

#change or add this line below

NameVirtualHost 192.168.1.1:80

#save and exit

Create a new virtualhost file

We need to enabled our new Website

root@athena:/etc/apache2/sites-available#a2ensite inferno.web.id

Restart Apache2 Webserver

root@athena:/etc/apache2/sites-available#/etc/init.d/apache2 restart

Create testing index.php

Testing it with IE

http://inferno.web.id
