I was not able to find my old config files (10 years old...), but the setup
should be:
proxy server:
- holds the public IP
- runs Apache with mod_proxy
- uses named virtual hosting to define www.example1.com, www.example2.com, ...
- each vhost uses mod_proxy to forward request to server1, server2, ...
The config should look like something like this:
<VirtualHost *>
ServerName example1.com
ServerAlias www.example1.com
<IfModule proxy_module>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://PRIVATE-IP-FOR-SERVER1
ProxyPassReverse / http://PRIVATE-IP-FOR-SERVER1
</IfModule>
</VirtualHost>
<VirtualHost *>
ServerName example2.com
ServerAlias www.example2.com
<IfModule proxy_module>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://PRIVATE-IP-FOR-SERVER2
ProxyPassReverse / http://PRIVATE-IP-FOR-SERVER2
</IfModule>
</VirtualHost>
and so on. Be careful, this config is not tested, I'm pretty sure required
directives are missing. And you should definitively add good logging
directives, because the proxy won't transmit the client IP to the final server.
server1, server2, ...:
- holds a private IP address
- runs Apache
- uses named virtual hosting to define *one* of www.example1.com,
www.example2.com... as the default vhost
If you want more than one vhost per server, you'll need to add
"ProxyPreserveHost On" to the proxy configuration.
