After creating a new user in putty and giving root privileges, I was getting an error during MySQL & Wordpress setup.
ERROR 1045 (28000): Access denied for user 'newuser'@'localhost' (using password: YES)
Also, you can find here https://stackoverflow.com/questions/10299148/mysql-error-1045-28000-access-denied-for-user-billlocalhost-using-passw guideline about how to solve this issue.
