hi
you're using rh, right?
if you are, just go out and get apt for red hat systems.
it's a frontend for the rpm package manager.
http://apt.freshrpms.net/
get the apt version for your version, install it after download with:
rpm -ivh apt-0.5.5cnc6-fr1.i386.rpm (example for rh9 apt)
after this, do:
apt-get update
after a while (should be no errors) you can install mysql like this:
apt-get install mysql mysql-server (installs client and server)
that's about it, try it out, and don't forget to read some more on the apt-subject ... try google
cheers..
