If you have lost the password for the MySQL root user, you can reset it by following these steps:
sudo systemctl stop mysql
--skip-grant-tables option. This will allow you to bypass the password authentication for the root user:sudo mysqld_safe --skip-grant-tables &
root user using the mysql command-line client:mysql -u root
You will not be prompted for a password.
root user:SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');
Replace new_password with the password you want to use.
mysql command-line client and stop the MySQL server:exit sudo systemctl stop mysql
sudo systemctl start mysql
You should now be able to log in to the MySQL server as the root user using the new password.
Keep in mind that these steps are specific to a Linux or Unix system. If you are using a different operating system, the steps to reset the root password may be different.
