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

When I try to connect the MySQL Server by command:

1. mysql -u root -p

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

For MySQL > 5.6:
