MySQL default password

Please I have followed this tutorial to this level that I got hooked:
I try to create “mysqladmin create asterisk” and I keep getting this error: “Access denied for user [email protected](using password NO)”

though I am hosting this on a VPS with an IP addres, should this be because it’s trying to create it on localhost. Though this is somehow vague to me. Please kindly help me out!

You are trying to create a databse without supply the mysql root user’s password.
