In this project, I'll walk you through the process of setting up a LAMP stack on a Raspberry Pi 4. LAMP stands for Linux, Apache, MariaDB (a drop-in replacement for MySQL), and PHP. This combination of software allows you to host dynamic websites and applications on your Raspberry Pi. Here's how to get started.

Hardware Required

• Raspberry Pi 4 (4GB or 8GB RAM recommended)
• MicroSD card (16GB or larger) with Raspberry Pi OS installed
• Power supply for Raspberry Pi
• Ethernet cable or Wi-Fi connection
• Case and cooling solution (optional but recommended)

Step 1: Update Your System

Before installing the LAMP stack, make sure your Raspberry Pi OS is up to date. Open a terminal and run the following commands:

sudo apt-get update
sudo apt-get upgrade

This will ensure that all packages are up to date and that your system is ready for the LAMP installation.

Step 2: Install Apache

Apache is the web server that will handle HTTP requests and serve web pages. To install Apache, run:

sudo apt-get install apache2 -y

After the installation, you can check if Apache is running by entering your Raspberry Pi's IP address in a web browser. You should see the default Apache welcome page.

Step 3: Install MariaDB

MariaDB is the database server that will store your data. To install MariaDB, use the following command:

sudo apt-get install mariadb-server -y

After installation, secure your MariaDB installation by running:

sudo mysql_secure_installation

Follow the prompts to set up your root password and secure the database server.

Step 4: Install PHP

PHP is the scripting language that will run on the server to generate dynamic content. To install PHP, run:

sudo apt-get install php libapache2-mod-php -y

Restart Apache to enable PHP:

sudo systemctl restart apache2

You can test your PHP installation by creating a simple PHP file:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php

Visit http://your_pi_ip/info.php in your browser to see the PHP info page.

Final Setup and Configuration

At this point, you have a fully functional LAMP stack running on your Raspberry Pi. You can now start developing and deploying your own web applications.
