So i accidentally changed my password for my root account like a year ago and forgot what it was when I needed to add a new database. Very bad for a sysadmin I know but it will probably happen to you at some point in your career if it has not already!
Here’s how to reset it: 1) Stop mysqld and restart it with the –skip-grant-tables option.
2) Connect to the mysqld server with this command:
3) Issue the following statements in the mysql client. Replace the password (MyNewPass) with the password that you want to use.
mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; mysql> FLUSH PRIVILEGES;
The FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.
4) Kill mysqld and restart it the normal way (/etc/init.d/mysql start). Your root password will be the new one you have selected.
