ERROR 1045 (28000): Access denied for user ‘root’@'localhost’ (using password: NO)

If this is the error you are getting then one of the solutions is to reset your root password on the MySQL database server.

$ pkill mysql

$ sudo mysqld --skip-grant-privileges

$ mysql

At this point you get the mysql command shell. You will need to update the root password and flush the table when you reset the password.

mysql> set UPDATE mysql.user SET Password=PASSWORD('YOUR_NEW_PASSWORD') WHERE User='root';

mysql> FLUSH PRIVILEGES;

Now that you’ve flushed your passwords, just restart your mysql daemon.

$ sudo pkill mysqld

$ sudo /etc/init.d/mysqld start

$ mysql -u root -p

Enter Password: YOUR_NEW_PASSWORD

mysql>

You should be all set now!
