How to add a new site to Apache and serve it under customized local url

First create directory where your site will be available from, ex: sudo mkdir /var/www/mysite

Create mysite config file in /etc/apache2/sites-available directory:

<VirtualHost *:80>
    DocumentRoot /var/www/mysite
    ServerName local.mysite

    DocumentRoot /var/www/mysite
    <Directory />
        Options FollowSymLinks
        AllowOverride All
    </Directory>
    <Directory /var/www/mysite>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        Allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
        AllowOverride All
        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Add following line to the end of /etc/hosts file: ::1 local.mysite

Enable new site in Apache server: sudo a2ensite mysite

Restart Apache to load and serve your new site: sudo service apache2 restart

Since now your site will be available at local.mysite url in any webbrowser.
