Help with running MySQL 5 on OS X Leopard

[Unnsse Khan]

Hello there,

I am running OS X Leopard on an Intel based iMac machine...
Followed the instructions to a T and everything works as described in:

http://hivelogic.com/articles/installing-mysql-on-mac-os-x/

Now, after running MySQL using launchd, when I try to login using:

mysql -u root

I get the following error:

Falcon:~ untz$ mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using  
password: NO)

What am I possibly doing wrong?

Many, many thanks!
