If you forgot your password or want to change it to your mysql:

start your terminal and enter:

sudo su

Enter pass for you system
Stop your mysql:

sudo /usr/local/mysql/support-files/mysql.server stop

Leave this window OPEN, run second terminal window and enter here:

mysql -u root

And change your password for mysql:

UPDATE mysql.user SET authentication_string=PASSWORD('new_password') WHERE User='root';

where "new_password" - your new pass. You don't need old pass for mysql.

Flush, quit and check your new pass:

FLUSH PRIVILEGES;

Close all windows and check your new pass for mysql. Good luck.

Try the command FLUSH PRIVILEGES when you log into the MySQL terminal   If that doesn t work  try the following set of commands while in the MySQL terminal    mysql -u root mysql gt  USE mysql  mysql gt  UPDATE user SET password PASSWORD  NEWPASSWORD   WHERE User  root   mysql gt  FLUSH PRIVILEGES  mysql gt  quit   Change out NEWPASSWORD with whatever password you want   Should be all set   Update  As of MySQL 5 7  the password field has been renamed authentication string   When changing the password  use the following query to change the password   All other commands remain the same   mysql gt  UPDATE user SET authentication string PASSWORD  NEWPASSWORD   WHERE User  root     Update  On 8 0 15  maybe already before that version  the PASSWORD   function does not work  as mentioned in the comments below  You have to use   UPDATE mysql user SET authentication string  password  WHERE User  root
