Before resetting and changing MySQL root password in Linux, make sure you have:

  • Access to an active MySQL database
  • Permission to connect to a Linux server running MySQL
  • Administrator-level privileges on the machine hosting the MySQL database
  • A text editor, Vim, vi, nano (vi is available by default on Linux)
  • Access to a command-line interface or terminal

Do you know that you need the MySQL root password to add new tables to the MySQL database?

Reset & Change MySQL Root Password in Linux

Now that you have fulfilled the prerequisites, let’s go into the details of resetting and changing the MySQL root password.

Step #1: Stop the MySQL Server

Before resetting the MySQL root password, you should halt the MySQL server to prevent unauthorized server access during the password reset.

Use the following command in the terminal to stop the MySQL server:

#service mysql stop

mysql stop MySQL Root Password

Step #2: Restart MySQL in Safe Mode

Now restart the MySQL service in safe mode, where you don’t need to provide a password.

In the terminal, enter the following command to start MySQL in safe mode as a background process:

#mysqld_safe --skip-grant-tables &

IMPORTANT: We strongly recommend using the –skip-grant-tables option with caution. It is a MySQL server startup option that turns off user authentication and potentially grants unrestricted access to the database. This option is often used for password recovery or fixing authentication issues.

Step #3: Connect to the MySQL Server

Now, connect to MySQL without specifying a password by entering the following command:

# mysql -u root

mysql root login MySQL Root Password

Since the server is in safe mode, you won’t see the password prompt. Instead, you will see the standard mysql> prompt of the MYSQL server CLI.

Step #4: Change the MySQL Root Password

Now, you can change the root password. For this, run the following SQL query, replacing new_password with your new password:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

change mysql password MySQL Root Password

IMPORTANT: We strongly recommend following the best practices for strong passwords. At the minimum, create a 20-character string containing a mix of uppercase characters, lowercase characters, digits, and special characters. Avoid using dictionary words and personal or corporate information.

Step #5: Reload Privileges

Note that while you have changed the MySQL root password, it is still not in effect. You need to refresh the privileges with the flush privileges command:

mysql> flush privileges;

flush privileges MySQL Root Password

Step #6: Exit and Restart the MySQL Service

Now, exit the current session with the exit command:

mysql> exit

Next, restart the MySQL service with the following command:

#systemctl start mysql

For MariaDB, replace “mysql” with “mariadb.”

Step #7: Verify the New Password

To confirm that the password change was successful, try logging in with the new password:

#mysql -u root -p

You will be prompted to enter the new password.
