After you have installed the Apache2, you need to configure virtual hosts.
The term Virtual Host refers to the practice of running more than one web site (such as company1.example.com,company2.example.com and anotherexample.com) on a single machine. Virtual hosts can be “IP-based”, meaning that you have a different IP address for every web site, or “name-based”, meaning that you have multiple names running on each IP address. The fact that they are running on the same physical server is not apparent to the end user.
All the apache VHOSTs are stored inside /etc/apache2/sites-available/vhosts.conf . You can create your own VHOST here, so apache2 will handle a certain domain or IP. For this sake you would need to use the following command:
sudo nano /etc/apache2/sites-available/yourdomain.conf
Inside you would need to add this:
<VirtualHost *:80>
ServerAdmin admin@domain.com
ServerName domain.com
ServerAlias www.domain.com
DocumentRoot /var/www/domain.com/public_html
ErrorLog ${APACHE_LOG_DIR}/domain.com_error.log
CustomLog ${APACHE_LOG_DIR}/domain.com_access.log combined
</VirtualHost>
You would need to edit this to your own setup, so change domain.com to your own domain.
After creathin this VHOST save it and exit the nano. You will now need to activate the VHOST.
Apache includes a certain directory inside its system wich will enable a VHOST:
sites-enabled: like mods-enabled, sites-enabled contains symlinks to the /etc/apache2/sites-available directory. Similarly when a configuration file in sites-available is symlinked, the site configured by it will be active once Apache2 is restarted.
Use this command:
sudo a2ensite yourdomain.conf
Now restart apache and it should all work:
sudo service apache2 restart
