I want to resolve ERROR 1045(28000) in mysql

I am learning mysql from dotinstall, but I have stopped with the following error:
I want to clear the error below and connect to mydb01, but I don't know how to do that.
I gave mydb01 permission to a user named cduser01 so that he could connect with the password '6AVAkig2', but when I had to say 'dbuser01@~' in the first line, I went ahead with 'dbuser', so I think I got an error.
You can delete it and start over from scratch, or you can do something else.
I would appreciate it if you could tell me the solution.
Thank you in advance.

mysql>create user dbuser @localhost identified by '6AVAkig2';
Query OK, 0 rows affected (0.01sec)
mysql>grant all on mydb01.* to dbuser01@localhost;
Query OK, 0 rows affected (0.00sec)
mysql>quit;
