I was trying to install something and now i got locked out of mysql... i ran these commands

i was supposed to do
GRANT USAGE ON webdatabase.* TO 'nobody'@'localhost' IDENTIFIED BY PASSWORD 'nopasswd';

i put
GRANT USAGE ON webdatabase.* TO root'@'localhost' IDENTIFIED BY PASSWORD 'mypass';

then realized i did it wrong, so i put the
GRANT USAGE ON webdatabase.* TO 'nobody'@'localhost' IDENTIFIED BY PASSWORD 'nopasswd';

thats all i did

now it wont let me log onto mysql.... gives me access denied.... is there any way i can get back in or do i have to reinstall now? and if i have to reinstall. whats the best way of getting all traces of old mysql out and put new mysql in... please help.. thanks (this is on linux btw mandrake distro)

You can try installing Phpmyadmin and if it gives you access, you can fix it from phpMyAdmin

Are you connecting from the localhost or another machine?

Why are you using
GRANT USAGE ON webdatabase.* TO 'nobody'@'localhost' IDENTIFIED BY PASSWORD 'nopasswd';

Instead of

GRANT USAGE ON webdatabase.* TO nobody@'localhost' IDENTIFIED BY PASSWORD 'nopasswd';
or
GRANT USAGE ON webdatabase.* TO nobody@localhost IDENTIFIED BY PASSWORD 'nopasswd';

and did you use flush privileges ?
