Question Single port open, multiple websites with Apache


Hello.

I have searched threads and couldn't find my question answered.

It's like this : I would like to have multiple websites with just one port open, and I know one can employ virtual hosts but I don't want to point to directories, but other servers running on localhost. So, if I have mldonkey serving on local port 6060 and SABnzbd on port 7221, I would like to have :

mldonkey.my_site.com -> redirects to -> localhost:6060
sabnzbd.my_site.com -> redirects to -> localhost:7221
www.my_site.com -> normal website

I have found something similar, but this is to have Apache redirect content from a specific port (443) :
Code:
<~VirtualHost myhostname:443>

   ~RewriteEngine on
   ~RewriteRule /mldonkey/(.*) ~http://admin@myhostname:4080/$1 ~[[P,L]]
   ~RewriteRule /mldonkey/(submit.*) ~http://admin@myhostname:4080/$1 ~[[P,L]]
   ~RewriteRule /mldonkey/(files.*) ~http://admin@myhostname:4080/$1 ~[[P,L]]

   ~ProxyPassReverse /mldonkey/(.*) ~http://myhostname:4080/$1

<Location /mldonkey/>
   Order allow,deny
   Allow from all
    ~AuthType Basic
    ~AuthName \"MLDonkey\"
    ~AuthUserFile /etc/apache2/keys.dat
    Require valid-user
</Location>
Is there a way to make this redirect work based on subdomain name?

Please help, and thanks in advance!

basically you want mod_proxy and probably not anything else really...

http://httpd.apache.org/docs/2.2/mod/mod_proxy.html

you're looking at mod_rewrite there mainly which is generally a fairly scary thing, but mod_proxy is normally just a rule in one direction (mapping requested uri on apache server to remote resource) and the reverse of it for translating back.

I kinda have it working...

This works :

Code:
NameVirtualHost *:80
<VirtualHost *:80>
    ServerName sab.my.domain.com

    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass / http://127.0.0.1:6060/
    ProxyPassReverse / http://127.0.0.1:6060/
    <Location />
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>
But my main website (requests on my.domain.com) vanishes. This should work (right?) :

Code:
NameVirtualHost www.my.domain.com:80
<VirtualHost www.my.domain.com:80>
</VirtualHost>

NameVirtualHost my.domain.com:80
<VirtualHost my.domain.com:80>
</VirtualHost>

NameVirtualHost sab.my.domain.com:80
<VirtualHost sab.my.domain.com:80>
    ServerName sab.my.domain.com

    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass / http://127.0.0.1:6060/
    ProxyPassReverse / http://127.0.0.1:6060/
    <Location />
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>
But I get [warn] NameVirtualHost sab.my.domain.com:80 has no VirtualHosts when I restart the Apache service and indeed does not work, since I get File does not exist: /var/www/html/sabnzbd on my logs when I access sab.my.domain.com.
What gives?

Success!

Code:
NameVirtualHost *:80
<VirtualHost *:80>
    ServerName www.my.domain.com
</VirtualHost>

<VirtualHost *:80>
    ServerName my.domain.com
</VirtualHost>

<VirtualHost *:80>
    ServerName sab.my.domain.com

    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass / http://127.0.0.1:6060/
    ProxyPassReverse / http://127.0.0.1:6060/
    <Location />
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>
It works now!

What are the security implications of using this? Any possibility of proxying through my server?

no, nothing risky really, nothing that doesn't already exist in the servicers you're running.
