Yes, it seems all you need is on board; can't say for sure though, because I run a Knoppix HD install. You can start MySQL by typing "/etc/init.d/mysql start" as root user in a shell; similarilly start Apache by typing "/etc/init.d/apache start". The Apache DocumentRoot is configured under /var/www (the direcetory that holds the files you see when you request a page under http://localhost/). PHP pages should have a ".php" extension.
