How to setup virtual host in ubuntu

Step 1: setup a virtual domain

open /etc/hosts and add a virtual domain with a specific local IP. In this file it contains ip and domain name separated by a space. You can also add the port using a colon with the IP. Lets assume that our virtual domain name is “domain.local” – and It will listen to the ip “127.0.0.1″

so we will add the following line to our /etc/hosts file
127.0.0.1 domain.local

now whenever you point to http://domain.local – your browser will actually open http://127.0.0.1

Step 2: configure virtual host with apache

here we will configure our newly added virtual domain against apache as a virtual host, and did I forget to say, with mod_rewrite enabled 

goto /etc/apache2/sites-available and create a file named “domain.local” – I recommend to keep it the same name as your virtual domain.
sudo gedit /etc/apache2/sites-available/domain.local

write the following contents inside. but please note to create the appropriate directory before linking your virtual host with that, for example we’ve create a folder named “/var/www/domain” and linked that directory as my document root in the following configuration file.

<VirtualHost *:80>

ServerName domain.local

DocumentRoot " /var/www/domain"

DirectoryIndex index.html index.php

<Directory " /var/www/domain">

Options FollowSymLinks

AllowOverride All

Order allow,deny

Allow from all

</Directory>

</VirtualHost>

now create a symbolic link of this file to /etc/apache2/sites-enabled directory as “domain.local”

sudo ln -s /etc/apache2/sites-available/domain.local /etc/apache2/sites-enabled/domain.local

Step 3: restart apache (or reload)
simple, either one of the followings

sudo /etc/init.d/apache2 restart

or

sudo /etc/init.d/apache2 reload

and you are done! now you can point your browser to http://domain.local
