[users@httpd] Virtual Hosts on physical servers
Hi All,
I'm setting up some servers for web hosting (they are vbox virtual servers) and need a little help with virtual hosts.
I could find examples on how to set up virtual hosts for most scenarios, but not my one, which is as follows:
I have a single IP address, with multiple web servers, so I somehow need www.hello.com to go to server1 and www.test.com to go to server2.
I know I can do this with NAT, but having to have people type www.hello.com:81 and www.test.com:82 is ugly, so is there a way apache can do this for me?

Hi Pete,
I checked out that page, but that only covers virtual hosts on the same server, not other servers.

For several years now I've been using virtualmin for just this
situation, a lovely and largely automated management tool. Available
with full function as GPL code and with extra bits in the for pay
VM-Pro version.

Hello,
It sounds like you want name-based virtual hosts. See
http://httpd.apache.org/docs/2.2/vhosts/name-based.html

that's for sure. A single Apache server is easier to manage and configure that many. "Keep It Simple" is a good rule. Think about a security update: you would have to deploy it on every virtual box servers, instead of doing it only once. That's to be taken into account too.

Thank you Patrick, that does make sense, I'll do some more reading up..
I'm actually starting to think it might just be easier to host all the sites on one server, although sooner or later I'm going to need to do this anyhow.

I'm going to take a look at my old config files, I've done that years ago, may be I've still some valuable pointers.

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.

As long as you have only one public IP address, you'll have to put a device (sofware or hardware) between your servers (private IP addresses), and the internet.
That can be NAT, but the port issue is not very nice for clients. Or, that can be a proxy, who will act almost like a NAT, but on the application level.
Your proxy can be an Apache Server, with mod_proxy, setup to forward client requests for www.hello.com to server1, and www.test.com to server2. That's not an unusual setup.
That could also be a Layer 7 switch, but it's very expensive, doing exactly the same job (somewhat easier to configure).
