MySQL Password Change

MySQL is a widely used relational database management system used in many applications and websites. I believe that if you are reading this article, you must already know about MySQL and be using it. MySQL provides a very secure and stable way to store and manage large amounts of data. However, like any other software, MySQL requires regular maintenance and updates. One of these aspects is changing the MySQL password when necessary. In this article, we will discuss how to change MySQL password to ensure the security of your database.

Why changing MySQL password is important

MySQL is a very powerful database management system that allows you to save a lot of sensitive information. Such a system will be a target for attackers who will try to break into your database, obtain your data and manipulate it. A strong password can reduce this risk. Whether you are a database administrator or a platform administrator, as long as you have access rights, changing passwords is one of your responsibilities.

Steps to Change MySQL Password

Changing the MySQL password is not a difficult problem, but it requires careful attention on many steps. Here are the basic steps to change your MySQL password:

Step 1: Log in to the MySQL database

To change your MySQL password, you first need to log in to the MySQL database. There are two different ways to achieve this. The first method is to use the mysql command line tool. You can open the mysql shell tool in the terminal and use the following command to connect to the MySQL server:

mysql -u root -p

In this command, the -u option is to select the user name, such as root; the -p option is to ask you to enter the password . If you successfully enter the correct password, you will see output similar to the following:

Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 4
Server version: 5.7.28 MySQL Community Server (GPL)

The second method is to use phpMyAdmin, a web-based application for managing MySQL databases. It provides a user-friendly interface through which you can easily manage MySQL database. To enter phpMyAdmin, just enter the URL into your browser. For example, if you are running MySQL on your local computer, you can enter the following URL to enter phpMyAdmin:

http://localhost/phpmyadmin

When you log in in phpMyAdmin, make sure to use the correct username and password.

Step 2: Select the user whose password you want to change

In MySQL, usernames and passwords are stored in the mysql.user table. To change a user's password, you need to run an UPDATE statement on the desired user record. For example, to change the password of a user named "Tom", you can run the following command:

UPDATE mysql.user SET Password = PASSWORD('mynewpassword') WHERE User = 'Tom' AND Host = 'localhost';

In this command, mysql.user is the table name; Password is the name of the password field; mynewpassword is the new password , you need to use it to replace the previous password; User is the user name; Host is the user's host address.

Note: If you are doing this via phpMyAdmin, simply find the users table ("mysql.user"), select the user whose password needs to be changed, and enter the new password in the "Edit User" tab That’s it.

Step 3: Refresh the permissions table

After changing the password, you need to refresh MySQL's permissions table for the changes to take effect. To refresh the permissions table, you can use the following command:

FLUSH PRIVILEGES;

This will refresh MySQL's permission cache to ensure that new passwords are applied correctly.

Step 4: Test the new password

After changing your password, you should test that the password is working correctly. You can use the following command to test:

mysql -u Tom -p

In this command, the -u option selects a username, such as Tom; the -p option requires you to enter a password. If you entered the correct password, you should be able to connect to the MySQL server correctly.

The above are the basic steps to change the MySQL password. Although they may seem simple, always be aware of security and follow best practices.

Summary

MySQL is a widely used relational database management system. While managing large amounts of data, system security is also very important. Changing your password can be a simple maintenance process, but ensuring the change is secure and correct requires following the correct steps. In this article, we explore the necessity of changing your MySQL password, and how to change your database password correctly. This is an important step in maintaining the security of your database system, and one we should all pay attention to.
