Reset mysql root password

This article will walk you through the process of resetting your MySQL root password, ensuring you regain access to your databases.

Understanding MySQL Root Password

What is the MySQL Root Password?

In MySQL, the 'root' is the username of the superuser account, which has full access to all databases on the server. The root password is the key to this account.

Why is the Root Password Important?

The root password is crucial as it:

Controls Access: It prevents unauthorized users from accessing your databases.

Manages Permissions: It allows the assignment of specific permissions to other users.

Resetting the MySQL Root Password

The process varies slightly depending on the operating system you're using. For this guide, we'll cover the procedure for a Linux/Unix system.

Step 1: Stop the MySQL Service

First, you need to stop the running MySQL service. You can do this using the following command in your terminal:

sudo service mysql stop

Step 2: Start MySQL Without Password Verification

Next, start MySQL in safe mode without password validation:

sudo mysqld_safe --skip-grant-tables &

Step 3: Access MySQL and Change the Root Password

Now, access MySQL as root:

mysql -u root

You'll enter the MySQL interface. Now, reset the root password:

FLUSH PRIVILEGES;
USE mysql;
UPDATE user SET authentication_string=PASSWORD('new_password') WHERE User='root';
Replace 'new_password' with your new root password.

Step 4: Restart the MySQL Service

Finally, exit the MySQL interface by typing exit and restart the MySQL service:

sudo service mysql restart

You have now successfully reset your MySQL root password!
