We can run two at once webserver (eg IIS and Apache) in a single server. With notes, the two Web server must use a different port (eg 80 and 81).

Now we will try to configure apache to use port 81 (of course can use other ports that are not used).

Create a new vhost configuration file in / etc/apache2/sites-enable / (path is relative), for example test.vhost

Write the following configuration:

Listen 81
NameVirtualHost *:81

<VirtualHost *:81>
    ServerAdmin This e-mail address is being protected from spam bots, you need JavaScript enabled to view it
    ServerName .unila.ac.id
    ServerAlias *.unila.ac.id
        DocumentRoot /var/www/doc_root
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/dir/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>
</VirtualHost>

then, restart apache

# apache2ctl restart

done
