ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES))

[Adrian Worley]

I am working from a book, (Learning PHP, MySQL & JavaScript, 6th Edition, by Robin Nixon), and have started the MySQL section of the work.The first thing I need to do is change to C:/"Program Files/Ampps/mysql/bin", which I have done, and can see this from the C: prompt. It then says to enter mysql -u root -pmysql. This results in the message:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES))

Simple question, what is wrong here?

Wave upon wave of demented avengers march cheerfully out of obscurity into the dream.
