Resetting Root Password in MySQL on Linux: Step-by-Step Guide

Have you ever forgotten the root password for your MySQL database on Linux? Don’t worry, it happens to the best of us. In this step-by-step guide, we will walk you through the process of resetting the root password in MySQL on Linux. Whether you are a beginner or an experienced user, this article will provide you with all the information you need to regain access to your MySQL database.

Introduction

Resetting the root password in MySQL is a crucial task that may be required in various scenarios. It could be due to a forgotten password, a compromised system, or simply the need to update the password for security reasons. Whatever the reason may be, it is important to follow the correct steps to ensure a successful password reset without any data loss.

Step 1: Stop the MySQL service

The first step in resetting the root password is to stop the MySQL service. This will ensure that no active connections are present and that the database is in a stable state for the password reset process. To stop the MySQL service, open a terminal and execute the following command:

sudo systemctl stop mysql

This command will stop the MySQL service on your Linux system.

Step 2: Start the MySQL service in safe mode

Once the MySQL service is stopped, the next step is to start it in safe mode. Safe mode allows you to start the MySQL server without loading the grant tables, which contain the user and privilege information. This will allow you to connect to the MySQL server as the root user without a password. To start the MySQL service in safe mode, open a terminal and execute the following command:

sudo mysqld_safe --skip-grant-tables &

This command will start the MySQL service in safe mode, allowing you to proceed with the password reset process.

Step 3: Connect to the MySQL server as the root user

Now that the MySQL service is running in safe mode, you can connect to the MySQL server as the root user without a password. To do this, open a new terminal window and execute the following command:

mysql -u root

This command will connect you to the MySQL server as the root user.

Step 4: Use the UPDATE statement to change the root password

Once you are connected to the MySQL server as the root user, you can use the UPDATE statement to change the root password. The UPDATE statement allows you to modify the data in the MySQL database. To change the root password, execute the following command:

UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root';

Replace ‘new_password’ with your desired password. This command will update the root user’s password in the MySQL database.

Step 5: Flush the privileges to apply the changes

After updating the root password, you need to flush the privileges to apply the changes. The FLUSH PRIVILEGES statement tells the MySQL server to reload the grant tables and apply the changes made to the user and privilege information. To flush the privileges, execute the following command:

FLUSH PRIVILEGES;

This command will apply the changes made to the root user’s password.

Step 6: Stop the MySQL service

Now that the password has been updated and the privileges have been flushed, you can stop the MySQL service in safe mode. To stop the MySQL service, open a new terminal window and execute the following command:

sudo pkill mysqld_safe

This command will stop the MySQL service running in safe mode.

Step 7: Start the MySQL service normally

With the MySQL service stopped, you can now start it normally. To start the MySQL service, execute the following command:

sudo systemctl start mysql

This command will start the MySQL service on your Linux system.

Step 8: Connect to the MySQL server using the new root password

Finally, you can connect to the MySQL server using the new root password. To do this, open a terminal and execute the following command:

mysql -u root -p

This command will prompt you to enter the new root password. Once you enter the password, you will be connected to the MySQL server as the root user.

Congratulations! You have successfully reset the root password in MySQL on Linux. You can now access your MySQL database with the new password and continue managing your data.
