How to Install MySQL on Ubuntu Server

Now that we have covered the prerequisites let’s move on to the installation process. The installation process is a straightforward process that consists of the following steps:

Step 1: Update Ubuntu Server

Before installing MySQL, it’s a good idea to ensure that your Ubuntu Server is up to date. You can update your server by running the following commands in the terminal window:

These commands will update all the packages on your server to the latest versions.

Step 2: Install MySQL

Once your server is up to date, you can proceed to install MySQL by running the following command in the terminal window:

 $ sudo apt install mysql-server 

This command will install MySQL on your server and start the MySQL service. During the installation process, you will be prompted to set a root password for MySQL. Make sure to choose a strong password and keep it safe.

Step 3: Secure MySQL

After the installation is complete, it’s important to secure MySQL by running the following command:

 $ sudo mysql_secure_installation 

This command will guide you through a series of security-related questions and prompts, such as removing anonymous users, disabling remote root login, and removing test databases. Follow the prompts carefully to ensure that your MySQL installation is secure.

Step 4: Verify MySQL Installation

Once you have installed and secured MySQL, you can verify the installation by running the following command:

 $ systemctl status mysql.service 

This command will display the status of the MySQL service and confirm that it is running. If the service is not running, you can start it by running the following command:

 $ sudo systemctl start mysql.service 

Step 5: Test MySQL

To test that MySQL is working correctly, you can log into MySQL by running the following command:

 $ sudo mysql -u root -p
