Abychom mohli mít pro každou virtuální doménu svůj konfigurační soubor je třeba nadefinovat default hosta, na kterém další virtuální hosti budou:

NameVirtualHost *:80 <VirtualHost *:80>

 Example for name based virtual host in debian:-

Apache 2.0, the default site is instead the first file (in alphabetical order) in the /etc/apache2/sites-enabled directory. After initial installation, there will be a symlink from 000-default in this directory to /etc/apache2/sites-available/default. As you can see from this, Apache 2.0 offers another level of abstraction in the Virtual Hosts by recommending putting the actual files in /etc/apache2/sites-available and then symlinking from there to /etc/apache2/sites-enabled. I would recommend following this convention, but it's not mandatory. In our example above, we would create two files, /etc/apache2/sites-available/default and /etc/apache2/sites-available/example.com. Our /etc/apache2/sites-available/default file would look like this:

NameVirtualHost *
<VirtualHost *>
ServerName incorrect.com
DocumentRoot /home/www/html/default
</VirtualHost>

And our /etc/apache2/sites-available/example.com would look like this:

<VirtualHost *>
ServerName www.example.com
ServerAlias example.com
DocumentRoot /home/www/html/example.com/html
CustomLog logs/www.example.com-access_log common
</VirtualHost>

We would then create symlinks to the /etc/apache2/sites-enabled directory with the ln -s

command: ln -s /etc/apache2/sites-available/example.com /etc/apache2/sites-enabled/example.com.

Now we have our Virtual Hosts configured, it's time to test. To start Apache 2, type /etc/init.d/apache2 start and fire up a browser and head to www.example.com

Example for IP based virtual host in debian:-

 /etc/apache2/sites-available/example.com would look like this:

<VirtualHost 192.168.1.20>
ServerName www.example.com
ServerAlias example.com
DocumentRoot /home/www/html/example.com/html
CustomLog logs/www.example.com-access_log common
</VirtualHost>

We would then create symlinks to the /etc/apache2/sites-enabled directory with the ln -s

command: ln -s /etc/apache2/sites-available/example.com /etc/apache2/sites-enabled/example.com.

Now we have our Virtual Hosts configured, it's time to test. To start Apache 2, type /etc/init.d/apache2 restart and fire up a browser and head to www.example.com
