MySQL is a popular relational database management system, and CentOS is a commonly used Linux server operating system. When you need to change the MySQL password on CentOS, you can follow the steps below.
Step 1. Log in to the MySQL server
You must first log in to the MySQL server as the Root user. You can log in using the following command:
$ mysql -u root -p
You will be asked to provide the password of the Root user, and then the MySQL console will be opened.
Step 2. Select the user whose password you want to change
Once you are logged in to the MySQL server, you can select the user whose password you want to change. You can list the current users using the following command:
mysql> SELECT user, host FROM mysql.user;
Select the user whose password you want to change from the list and record its username and host. Then select that user using the following command:
mysql> USE mysql; mysql> ALTER USER 'user'@'host' IDENTIFIED BY 'new_password';
Note to replace "user" and "host" with the actual username and host of the user you selected, and "new_password" with the new password of your choice.
Step 3. Restart the MySQL server
After completing the password change, you need to restart the MySQL server for the new password to take effect. The MySQL server can be restarted using the following command:
$ systemctl restart mysqld
Step 4. Verify the new password
After restarting the MySQL server, log in with the new password and verify that it is valid. You can log in using the following command:
$ mysql -u user -p
Enter the actual username and new password of the previously selected user. If logged in successfully, you will be able to access the MySQL command line prompt and execute database commands.
Conclusion
Changing MySQL password is an easy task, just follow the simple steps above. You can use a similar process to change your MySQL password whether you are running on the CentOS operating system or not. Make sure your new password is strong enough to keep your system secure.
