Introduction

Greetings, fellow tech enthusiasts! Are you looking to set up a MySQL server on your Debian system? If so, this article is perfect for you! MySQL server is a popular open-source relational database management system that allows you to manage and store your data effectively. It has a vast range of applications, from web development to enterprise-grade data management. In this guide, we will walk you through the process of setting up MySQL server on Debian, including its advantages and disadvantages and FAQs. So, sit tight and let’s get started!

What is MySQL Server?

MySQL server is an open-source relational database management system that helps to manage and store data effectively. It is widely used in web development and enterprise-level data management due to its flexibility, scalability, and reliability. MySQL server is the most popular database system on the web, powering popular websites like Facebook, Google, and Twitter.

Why Use Debian for MySQL Server?

Debian is a popular and stable Linux distribution that is well suited for server deployments. It has a vast community of developers and users that provide excellent support and frequent updates. Debian’s package management system makes it easy to install and manage software packages, including MySQL server. Additionally, Debian has a reputation for being secure, which is essential when dealing with sensitive data.

Prerequisites

Before we dive into the installation process, we need to ensure that we have all the necessary prerequisites. Here’s what you need:

Prerequisite	Description
Debian server	A Debian server or a virtual machine running Debian
SSH client	An SSH client like Putty or Terminal
Sudo privileges	Sudo privileges to install packages and modify system configurations

Setting up MySQL Server on Debian

Step 1: Updating the System

Before installing any new software package, we need to update the system to ensure that we have the latest security patches and bug fixes. Connect to your Debian server using SSH and run the following command to update the system:

sudo apt update && sudo apt upgrade -y

This will update all the packages installed on your system to their latest version.

Step 2: Installing MySQL Server

Now that the system is up to date, we can proceed with installing MySQL server. Run the following command to install the MySQL server package:

sudo apt install mysql-server -y

During the installation, you will be prompted to enter a root password for MySQL server. Make sure to choose a strong password and remember it. Once the installation is complete, start the MySQL service using the following command:

sudo systemctl start mysql

You can verify that the service is running by checking its status using the following command:

sudo systemctl status mysql

It should output that the service is active and running.

Step 3: Securing MySQL Server

By default, the MySQL server installation is not secure. It is recommended to secure it by running the following command:

sudo mysql_secure_installation

This will guide you through a series of prompts to secure your MySQL server installation. You will be prompted to enter the root password, remove anonymous users, disallow remote root login, and remove test databases. It is recommended to answer “Yes” to all prompts for maximum security.

Step 4: Creating a New MySQL User and Database

Now that MySQL server is up and running, we can create a new user and database to manage our data. Connect to MySQL server using the following command:

sudo mysql -u root -p

Enter the root password when prompted. Once connected, run the following command to create a new user:

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';

Replace “newuser” and “password” with your desired username and password. Next, create a new database using the following command:

CREATE DATABASE newdatabase;

Replace “newdatabase” with your desired database name. Finally, grant the new user access to the new database using the following command:

GRANT ALL PRIVILEGES ON newdatabase.* TO 'newuser'@'localhost';

Now, you can exit MySQL using the following command:

exit;
