how to setup a virtual host in apache to same server url of some port

Question

i want to setup a virtual host to the url of with some port

e.g. my server name is rockstar.net

so i want to setup a subdomain on my server.where i should access the content of http://rockstart.net:8001/

what i tried :

<VirtualHost *>
  ServerName content.rockstart.net
  DocumentRoot "http://rockstart.net:8001/"

</VirtualHost>

which is giving error

Warning: DocumentRoot [/etc/apache2/http:/rockstar.net:8001/] does not exist

Answer 1

The DocumentRoot points to the folder in the local folder structure where the site is hosted, e.g. (on a linux system) /var/www/html/rockstart.net. The port number must be included in the VirtualHost definition. Therefore your VHost definition should rather look like:

<VirtualHost *:8001>
  ServerName content.rockstart.net
  DocumentRoot "/var/www/html/rockstart.net"

</VirtualHost>

However, this will still require the users to enter http://rockstart.net:8001 into their browser. I suspect what you had in mind was actually more like a redirection. If the redirection needs to include a change of port (i.e. from 8001 to 80) then you either need to use a reverse proxy or a DNAT firewall.

Or, if the content that is to be made available under http://content.rockstart.net is located on the same server where rockstart.net is located, you could simply use a

<Location> 

redirection within the file system. However, in that case I wonder why you don't just point content.rockstart.net at the same location where rockstart.net:8001 gets its content from?

Answer 2

The DocumentRoot directives describes the physical path on the machine, like /var/www/myvhost.net.

Set this directive as a path and use ServerName for the first and ServerAlias for every other name you want to point to your files, defined in DocumentRoot.
