Topic: How to setup ONE Fixed IP serving multiple servers on VMs

[satimis]

Hi all,

Host Ubuntu 14.04 desktop
VMs Ubuntu 14.04 desktop/server edition
VirtualBox

I have several web-servers running on VMs, each with its own domain/subdomain and internal IP address. The web-servers are connected to Internet via a router. But I have only one Fixed IP allocated by ISP. Please advise how to set up their static IP so that they can be browsed on Internet?

Thanks in advance

Reverse proxy to the VM's on the host OS should work.

Thanks for your advice.

I suppose you referred to;
HAProxy
http://www.haproxy.org/

I'm now searching for steps/document re how to configure it on domain base? Can you help?

Besides can I install HA Proxy on a VM instead of on the Host. Because I expect retain the latter clean solely for running VirtualBox.

If "NO" I'll get another machine for testing HA Proxy.

Thanks

reverse proxy is feature of apache - mod_proxy

See links below

Hi,

Thanks for your advice and links.

I'm prepared testing it. But my concerned is whether I can create an Apache server running on a VM for this test instead of installing Apache on the host? I don't expect installing Apache on the host because I expect keeping it clean solely for running VirtualBox. Otherwise I'll find another PC for this test.

Thanks

You can install a "minimal" Apache on a VM with the ONE IP, this only proxies the request, based on the Host header.
