Installing MySQL

Learn about the importance of installing MySQL, choosing the right edition, and completing the setup process across different operating systems.

We'll cover the following...

Imagine you are about to build a new application, an OnlineStore that tracks products, customers, and orders. Before you can think about storing all that valuable information, you need a reliable system to manage it. That is where MySQL comes in. The very first step is to install it on your computer. This lesson will guide you through that essential process.

By the end of this lesson, we will be able to:

  • Understand why installing a Database Management System (DBMS) like MySQL is a crucial first step.

  • Identify different MySQL editions and learn how to select the one that best suits our needs.

  • Walk through the general steps for downloading the MySQL software.

  • Get a clear overview of the installation process on common operating systems: Windows, macOS, and Linux.

  • Successfully verify that our MySQL installation is complete and operational.

Why bother installing MySQL?

Before we get into how to do it, let’s take a moment to understand why it matters. Installing a Database Management System like MySQL is fundamental because it provides the software that allows us to create, manage, and interact with databases. Think of it as building the warehouse before we can start organizing our goods.

Press + to interact

MySQL is a robust, popular, and open-source relational Database Management System (RDBMS). It acts as the backbone for countless applications, from small personal projects and dynamic websites (like our future OnlineStore) to large-scale, complex enterprise solutions. Without installing it, we simply wouldn’t have the tools to store, retrieve, and manage data efficiently and securely.

Choosing your MySQL edition and version

MySQL comes in a few different flavors, known as editions, each tailored to specific requirements. It’s important to pick the one that aligns with our goals.

  • MySQL community server: This is the free, open-source version. It’s incredibly popular, widely used, and perfect for learning, development, and many production environments. We’ll focus on this edition throughout this course.

  • MySQL enterprise edition: This is a commercial version that includes all the features of the Community Server plus additional enterprise-grade tools, features (like advanced security and high availability options), and official support from Oracle.

  • MySQL cluster CGE: This is another commercial edition designed for applications requiring extremely high availability, scalability, and real-time performance, often used in telecommunications and online gaming.

Besides editions, there are also different versions (e.g., MySQL 8.0, 8.1, 8.2). Generally, it’s a good practice to use the latest stable release of the Community Server for new projects, as it will have the newest features and security updates. For our OnlineStore project and for learning purposes, the MySQL Community Server is an excellent choice.

Prerequisites for installation

Before we start downloading and installing, it’s good to ensure our system is ready. While specific requirements can vary slightly between MySQL versions and operating systems, here are some general prerequisites:

  • Sufficient disk space: MySQL server software and the databases we create will take up disk space. Ensure you have at least a few gigabytes free. ...
