I really need help, I'm doing this as root, I have created the password
for the root user in mysql, and I can enter to mysql with it and create
and/or drop databases and all.
Both mysql and apache daemon are running, i have all the perl modules needed.
I mean don't know what is happening. if there would be something else to
do pleae tell what is it!
Should I look at those lines mentioned above?
Ok I'll wait thnx fornow bye.
