MySql setup problem

[blaci]

Hi!

I installed the full version of Mandrake 8.2.
The problem is that i can't setup the mysql server.
When i tried: mysql -u root mysql; the server responded: acces denied for root@localhost !!

Then tried the command mysql_install_db. But when i wanted to sign in: still acces denied.

Then i used mysqld --skip-granted-tables. BUT after that even for the 'mysql' command the server returned 'Acces denied'.

What to do?

Thanks for your answer!
