How to Change Root Password of MySQL or MariaDB in Linux: Step-by-Step Guide

MySQL and MariaDB are popular relational database management systems used for storing and managing data. The root user in MySQL and MariaDB has extensive privileges and control over the databases, making it a prime target for potential security breaches. It is crucial to change the root password regularly to enhance the security of your system. In this article, we will explore the step-by-step process of changing the root password of MySQL or MariaDB in Linux.

Changing the root password of MySQL or MariaDB in Linux is a fairly straightforward process. First, you need to log in to the machine as the root user. Once logged in, you can use the mysqladmin program to change the root password by running the command “mysqladmin -u root password ‘new_password'”. After entering the command, the root password of MySQL or MariaDB will be changed to the new_password you provided. You can also use the command line program mysql to change the root password by running the command “SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘new_password’);”. Once the command is executed, the root password will be changed to the new_password you provided. It is important to remember to use a strong password for your root user to ensure the security of your database.

Changing the root password at regular intervals is essential for maintaining the security of your MySQL or MariaDB server. The root user has complete access and control over all databases and tables within the system. By changing the root password periodically, you can prevent unauthorized access to your data and protect against potential server breaches.
