Morning,
I have 4 Computer nodes all running a base install of Ubuntu Server x64

I wish to start hosting websites and want to isntall LAMP (Linux+Apache+MySQL+PHP4) and Mail.
I will also be using one of the nodes as a file server.
I will use Webmin as my administration.

Node 1: Apache+PHP4, phpMyadmin, Webmin
Node 2:
Node 3:
Node 4: BIND9, Webmin

I will upgrade later as I go along, maybe add new nodes.


As listed above what should be installed on each of my server to accomplish this goal?
I might ass a 5th Node for my file server.

------------------------------------------------------------
Background:
I attempted to so HA+Hearbeat with 2 Nodes and then the other 2 Nodes were Apache webservers. (I was using a howto guide). That worked but it seems like overkill and too much. So I am now looking for recommendations, should I have continued that route or is that a faster cheaper solution...

I'm not sure of your question. All of the software you already listed is what you use. Are you asking what OS you should use?
lol

If you want to host websites professionally, you really have to cluster your servers. What you can do as well is building a xen cluster, so you can make more effective use of your servers. Depending on your hardware specs, you can create many more virtualized servers without buying extra hardware.

To be honest, I would also build a good firewall server that separates the web servers from the application and database servers. Security shouldn't be forgotten.

Thank you...
