The thing is that I'm installing a new linux webserver on
a already installed Ubuntu 8.10. Can anyone point/send
me a excellent tutorial covering all the basic steps to
*install Apache + PHP + MySQL and how to configure it
to be the most secure possible?*

I'll be "runing a intranet" on a remote server (outside the
company facilities, actualy it's in another country)
accessible via internet, So security is kinda important,
'cause financial and employes information will be hosted
on this server.
