Not a warning.
I was welcoming you to the site. My apologies if it read like a warning.
I'm glad to have you join the site and hope that you'll visit often. We have nearly 100 members now, but the site could use some more activity.
So for your server, it looks like you have the right base software. MySQL is often also installed on Linux servers, but is really only useful if you need databases.
I've never used SUSE linux, most of my experience is with Red Hat Enterprise Linux... I use a clone version of RHEL4 from
www.centos.org It's basically an exact copy of RHEL but is called CentOS instead and is also free.
For your server you may also want to look for a firewall script if you're not familiar with setting up a firewall with iptables. APF is a good one for that:

If most of your sites will be built using PHP, you can speed things up a lot by using a PHP caching program such as APC:

Will you be using your server for sending emails? Qmail is pretty good with that and easy to use if setup using the guide at
