Securing Your Database: Changing Default Passwords

It is crucial to alter the default passwords for your database's root or system administrator accounts. Failing to do so leaves your system vulnerable to unauthorized access and potential hacking.

MySQL Root Password Modification

In MySQL, the default system administrator account is named 'root'. Password changes are performed using the mysqladmin utility, accessed through the command line.

Two commands must be executed to successfully update the root password. This ensures the change is applied both locally and remotely.

Command Syntax

The basic syntax for these commands is as follows:

mysqladmin -u root password "newpassword"

mysqladmin -u root -h host_name password "newpassword"

The -h host_name parameter specifies the host where the MySQL server is running.

Example Implementation

Consider the following example, utilizing the password 'ws8dr8as3':

mysqladmin -u root password ws8dr8as3

mysqladmin -u root -h localhost password ws8dr8as3

This sequence will change the root password for both local and remote connections.

Database Server Restart

After executing the password change commands, it is essential to restart the MySQL server. This ensures the new password is fully implemented and active.

Restart Command

The following command is commonly used to restart the MySQL server:

sudo /etc/init.d/mysql restart

This command requires administrative privileges (sudo) to execute successfully.
