Install MySQL on Ubuntu

Every business application needs a database to store data and deliver/retrieve capabilities to application processes. 

While there are several popular options, MySQL remains a widely recognized open-source relational database management system (RDBMS) used for creating, storing, and retrieving data. It is integral to several popular stacks, including LAMP and LEMP. 

 As developers add new features, you must install the latest MySQL version on your server. This is a critical step in optimizing your stack and ensuring the business applications can leverage the latest database features.

How to install MySQL on Ubuntu 20.04 is a crucial skill for developers and sysadmins.

This tutorial will guide you through the process of installing the latest MySQL version in an Ubuntu environment. We’ll begin by adding the MySQL software repository, followed by installing the MySQL package on the server. 

Let’s start with the prerequisites of the process.

Install MySQL on Ubuntu 20.04

You need the MySQL Server package to install the MySQL database server and client on Ubuntu 20.04. Here are the steps of the process:

Step #1: Repository Update

Make sure you are installing the most recent version of MySQL by updating the system package repository.

Start by entering the following command into the terminal. Note that you will need to enter the admin password to initiate the process:

#sudo apt update

sudo apt update

Next, run the following command to upgrade the system’s package index. When asked to proceed with the upgrade, type Y and press ENTER

#sudo apt upgrade

sudo apt upgrade

Step #2: Install MySQL

After the package repository has been successfully updated, use the following command to install the MySQL Server. Press ENTER after selecting Y to proceed with the installation when prompted:

#sudo apt install mysql-server

sudo apt install mysql server

During the command execution, the system will download MySQL packages and install them on the system.

Step #3: Verify MySQL Installation

Once the installation finishes, you should verify the installation by checking the version information. For this, run the following command in the terminal:

#mysql --version

mysql version

Step #4: Secure the MySQL Installation

Out of the box, MySQL is not very secure. So, after the installation, the first order of business is to secure the database. 

MySQL provides a dedicated security script to set up the database security. Run the following command to initiate script execution: 

#sudo mysql_secure_installation

sudo mysql secure installation

Type in the password for the root user and select Y to configure the VALIDATE PASSWORD component. This component checks whether the new password is sufficiently strong.

You can select one of the three levels of password validation:

  • 0. Low: A password with a minimum of eight characters.
  • 1. Medium: A minimum of eight characters that should contain special, mixed-case, and numeric characters.
  • 2. Strong: A minimum of eight characters, including special, numeric, and mixed case characters; the password is then compared to a dictionary file.

Note that this password strength will be required for all user passwords. 

After that, the script asks you to input your password again for confirmation. While you are configuring a password for the root user, it’s important to note that this user does not need to undergo password authentication during the MySQL login process.

The program calculates how strong your password is and asks for confirmation before continuing. To change the password, press any key or press Y if you’re happy with the current one.

After that, the script requests the following security options features:

  • Remove anonymous users?
  • Disallow Remote root login?
  • Remove the test database.
  • Reload privilege tables now?

We recommend entering Y for these questions. 

Step #5: Verify That the MySQL Service is Functional

At this point, you have a secure MySQL installation on your server. In most cases, the MySQL service should be running automatically. We recommend checking the MySQL service status by executing the following command:

#sudo systemctl status mysql

If the MySQL service is up, you’ll see the active status in green:

sudo systemctl status mysql

Step #6: Log in to MySQL Server

Finally, run the following command to log in to the MySQL server:

#sudo mysql -u root

sudo mysql u root

You can see that the prompt changes from the terminal to the MySQL shell. You can now create databases, run queries, and check out your newly configured MySQL system.
