This article covers how to change root mysql password in Windows/Plesk.
Step 1. Go to C:\Program Files\Parallels\Plesk\Databases\MySQL\Data\my.ini and add the following line at the top:
skip-grant-tables
(this will let you access MySQL with no password)
Step 2. Restart MySQL
Step 3. Open CMD and change to the directory C:\Program Files\Parallels\Plesk\Databases\MySQL\bin\
Step 4. Go into the MySQL command utility, (notice you are not using a password):
mysql -u root mysql
Step 5. Change the password using these two commands
mysql> UPDATE mysql.user SET Password=PASSWORD(‘New_Pass_Word’) WHERE User=’root’;
mysql> FLUSH PRIVILEGES;
(New_Pass_Word is the new password you would like to use )
(if the root user doesn’t work when updating the password in Plesk try changing the user from ‘root’ to ‘admin’ in the command above)
Step 6. Restart mysql
Step 7. Go into Plesk and update the MySQL password to the changed
Step 8. Remove the line ‘skip-grant-tables’ from the my.ini file and restart mysql
