Virtual hosts allow you to host multiple websites on a single server, while modules extend Apache’s functionality. Use the following command to enable the rewrite module, which is commonly used for URL manipulation:

sudo a2enmod rewrite

Finally, configure your firewall to allow HTTP and HTTPS traffic. If you’re using UFW (Uncomplicated Firewall), run the following commands:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable

With Apache installed and configured, you’re ready to move on to the next component of the LAMP stack: MySQL.

Setting Up MySQL: The Database Management System

MySQL is a powerful and widely-used open-source relational database management system (RDBMS). It provides a robust platform for storing and managing data, making it an essential component of the LAMP stack. In this section, we’ll guide you through the process of installing and configuring MySQL on Ubuntu 24.04 LTS.

sudo systemctl status MySQL

You should see a message indicating that MySQL is active and running. Next, secure your MySQL installation by running the following command:

sudo mysql_secure_installation

This script will guide you through a series of prompts to improve the security of your MySQL server. You’ll be asked to set a root password, remove anonymous users, disallow remote root login, and remove test databases. It’s crucial to follow these steps to protect your database from unauthorized access.

After securing your MySQL installation, you can create a new database and user for your web application. Log in to the MySQL shell by running:

sudo mysql -u root -p

Enter the root password you set earlier, then create a new database and user with the following commands:

CREATE DATABASE your_database_name;
CREATE USER ‘your_username’@’localhost’ IDENTIFIED BY ‘your_password’;
GRANT ALL PRIVILEGES ON your_database_name.* TO ‘your_username’@’localhost’;
FLUSH PRIVILEGES;
EXIT;

Replace “your_database_name,” “your_username,” and “your_password” with your desired database name, username, and password. With MySQL set up and configured, you’re ready to move on to the final component of the LAMP stack: PHP.

Configuring PHP: The Server-Side Scripting Language

PHP is a popular server-side scripting language used for web development. It enables developers to create dynamic and interactive web pages by embedding code within HTML. In this section, we’ll guide you through the process of installing and configuring PHP on Ubuntu 24.04 LTS.
