Hi everyone! This is my first post on this forum. This site helped me a lot in learning how to install and configure a Linux system. I would like to build a server with dns,apache(php,mysql etc.),smtp,pop3,imap,ispconfig etc. according to a howto posted on this site. I prefer OpenSuSE for my server software. The problem i will probably have in the near future will be effeciency. My server may be overloaded and my users unhappy.My suggestion is to write a howto on building a cluster out of a coupple of computers based on the howto which described installing dns,apache(mysql and php),pop3,smtp,ispconfig on OpenSuSE 10.1. This would be very usefull. Thanks in advance.
