Running two webservers on same network

So I would leave this alone and do it via the RevProxy.

i.e.:
.....
ProxyPass / http://www.server1.com:81/
ProxyPassReverse / http://www.server1.com:81/

As for the /etc/hosts this is the anoying part every time you add a new site in ISPConfig you need to conf the RevProxy server to point to the new host.

i.e. add in the /etc/hosts the line to the server
eg:
192.168.1.12 auth.server1.com auth
192.168.1.11 www.server1.com server1.com
192.168.1.11 album.server1.com
192.168.1.11 server2.com www.server2.com

you also need to create the new vhosts file (/etc/apache2/sites-available) and run:
a2ensite server3.vhost

And don't forget you will need to restart Apache!!

This I dont understand. My new website (host?) will be on the second machine. But I create it in server1's control panel? Why do I need to create a new vhost file? Doesnt ISPConfig do this when you create a new site in sites-available? I am totally confused by this process.

Also, a2ensite is not a command on my OpenSuse box. What does this program do?

By the way, ISPCOnfig does not install on port 81. It installes the control panel on port 8080 by default but all websites are on port 80. Where did 81 come from?

The way I understand it works is if you have a front end webserver that accepts all HTTP requests and then forwards it on as per your hosts file (or your internal DNS server).

My VirtualHost config looks like this:
<VirtualHost *:80>
ServerName www.server1.com
ServerAlias server1.com

ProxyRequests Off

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

ProxyPass / http://www.server1.com/
ProxyPassReverse / http://www.server1.com/
</VirtualHost>

I have put the domains in the hosts file with the server ip as follows.

i.e.
/etc/hosts
192.168.1.11 www.server1.com
192.168.1.12 www.server2.com

You need to do it this way as the servers (192.168.1.11 & 192.168.1.12) need the host address to be passed in the GET request.

Personaly I run ISPconfig on a different port number but I have 4 vmware servers working (3 X Debian Lenny, 1 X Ubuntu), 1 is the front end Rev Proxy server that has a FIREWALL installed etc...

I think I did it with :
http://www.howtoforge.com/apache_rev...roxy_ispconfig
and with referance:
http://httpd.apache.org/docs/2.0/vho...les.html#proxy

Kind regards
Stephen

So this configuration file goes on server 1 (the primary webserver aka server1.com per your documentation) and is saved in /apache2/v.host/ as foo.conf (correct)?

What I did was point port 80 from my ADSL router to one of my internal webservers and made sure that it was working as it was ment to. If you are vhosts on your internal server make sure it works.

I then built the my front end RevProxy server as per above and changed my ADSL router to point to the new front end Revproxy server.

So in short, make sure your back end servers works as normal as if each is was itself a front end server then do not touch them. Then configure the RevProxy server to forward requests to your internal server. You should end up with your normal webserver conf files on your internal servers and the



conf's on your front end server and that is it.

If it helps this is my conf file of one of my internal servers:



And ofcourse the hosts file:


hope it helps

So where do these conf files go on the front end and the back end servers? I think I am getting confused. There are the conf files in the /apache2/vhost.d directory, vhost files in the /sites-available/ directory with symlinks to /sites-enabled. What goes where?

Where does the rev proxy conf file go?
