MySQL

This is how i first setup my server so it has basic functions like Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. Most of this has setup is based off various different tutorials i've used.

As my server is hosted in a Data centre they install the base system (CentOS 5.x) for me but if you have physical access you can do this yourself, you just need to grab the 1x dvd or 6x cd images mirror list here
