"This tutorial shows how you can install an Apache2 webserver on a Debian Lenny server with PHP5 support (mod_php) and MySQL support.
"First we install MySQL 5.0 like this: aptitude install mysql-server mysql-client
"You will be asked to provide a password for the MySQL root user - this password is valid for the user root@localhost as well as root@server1.example.com, so we don't have to specify a MySQL root password manually later on."
