How? starting and connecting to mysql.

I've installed the mysql that came with my SuSE 8.2. Questions: How do I start it? What username and password do I use to connect? ( Wasn't asked for any password during the install. ) Can I use Knoda as a client or is there a better GUI client? I did open the 'Run Command' window and ran 'rcmysql start' as root, got no error and hoped mysql started ok. I still wasn't able to connect with Knoda. Maybe I had the wrong connect data. 'localhost' 'root' '(rootpassword)'. Any thoughts? Thanks, Patrick Hooker
