This confirms that MySQL is installed and ready to use.

Securing Your MySQL Installation

By default, MySQL is installed with some security vulnerabilities, so it's important to secure your installation. MySQL provides a command to set up basic security settings, such as configuring a password for the root user and removing insecure default settings.

Step 4: Run the MySQL Secure Installation Script

Now we will set the VALIDATE PASSWORD component to improve Security

sudo mysql_secure_installation

This script will guide you through several security settings:

• Set a root password: Choose a strong password for your MySQL root user.
• Remove insecure default settings: It will prompt you to remove test databases and disable remote root login.
• Improve password validation: It asks if you want to enable password validation to ensure strong passwords.

Step 5: Test the MySQL Server

Once the security configuration is complete, test whether MySQL is running properly:

sudo systemctl status mysql

If MySQL is running correctly, you should see output indicating that the service is active and running. If not, you can start the MySQL service using:

sudo systemctl start mysql

Getting Started with MySQL

Once MySQL is installed and secured, let’s log into the MySQL shell to start using it.

Step 6: Log into MySQL

To get started with MySQL, type the following command to go to the root directory.  

sudo mysql -u root

You’ll be prompted to enter the root password you set earlier. Once entered correctly, you’ll be logged into the MySQL shell.

Verify MySQL Installation by Creating a Database

To ensure everything is set up properly, let’s create a database and verify that MySQL is working as expected.

Step 7: Create a Database

To create a new database, run the following command within the MySQL shell:

CREATE DATABASE database_name;
