Can linux host mutiple websites with one domain's different third domains? - dns

Question

I recently made some projects on raspberry pi with linux Debian Jessie, and I am interested in porting forward websites hosted on raspberry pi to a domain I owned.
From what I learned, it is possible to make each individual website on raspberry link with configured port according to apache , for example /home/pi/html/website01 -> port 11235 website02 -> 11236 so that I can browse the websites in private network. However, the domain I have is managed by godaddy, they provide the Chain without port, so that I can't redirect one of my third level domain(ex dashboard.domain.com to my dynamic dns hostname xx.dtdns.net with the port.
Is there any possible way or idea to get it work? I am lack of knowledge of nameserver, but I have an idea that using vpn or vps to map users to my private network instead of godaddy domain manager. I have alreay built the openvpn with cert and pptp vpn on my raspberrypi. Is it possible or what's next step?
Thanks, please give me some idea.

One solution would be to use Virtual Hosting in Apache on your Raspberry. Install Apache2 on PI with:
apt-get install apache2
Create a new conf file in /etc/apache2/sites-available or use an existing one. Add the ports for different site directories:
<VirtualHost *:11235>
DocumentRoot /var/www/w1
<Directory /var/www/w1>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
</VirtualHost>
<VirtualHost *:11236>
DocumentRoot /var/www/w2
<Directory /var/www/w2>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
</VirtualHost>
and then set Apache tolisten on the ports in the /etc/apache2/ports.conf file:
Listen 11235
Listen 11236
Restart the Apache service. You should now be able to browse both ports using the same ip address. If your ip was 111.111.111.111 then w1 directory on 111.111.111.111:11235 and 111.111.111.111:11236.
If your domain is pointing to a IP, you can use different hostnames without making change to DNS. If you domain was mydomain.com, you could instead add new virtual host names with:
<VirtualHost *:80>
ServerName w1.mydomain.com
DocumentRoot /var/www/w1
<Directory /var/www/w1>
Options +Includes -Indexes +FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
<VirtualHost *:80>
ServerName w2.mydomain.com
DocumentRoot /var/www/w2
<Directory /var/www/w2>
Options +Includes -Indexes +FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
