MySQL: How to reset the root account

I just managed to mess up the MySQL root account. Not a smart idea. After some MySQL manual reading and some serious Google-Fu, I figured out how to fix it.

  1. Stop the mysql server
  2. Add the following to the my.cnf file
  3. Start the mysql server
  4. Start a mysql client and run the following query
    REPLACE INTO mysql.USER VALUES ('localhost','root',PASSWORD('blah'),'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','',0,0,0,0);
  5. Quit the mysql client
  6. Stop the mysql server
  7. Remove what we added to my.cnf in step 2
  8. Restart the mysql server
