Streamlining Your Server Setup: Installing PHP 8.4, Composer, Nginx, and Certbot

Setting up a web server with the latest software can sometimes feel like a complex task. This guide provides a simplified, step-by-step approach to installing essential components like PHP 8.4, Composer, Nginx, and Certbot on a Debian-based system. This combination is frequently used for deploying modern web applications, offering performance, security, and easy dependency management.

Understanding the Components

Before we dive into the installation, let’s briefly clarify what each component does:

• Nginx: A high-performance web server known for its stability, speed, and ability to handle a large number of concurrent connections. It serves as the front-facing entry point for web requests.
• PHP 8.4: The latest version of the popular server-side scripting language, offering significant performance improvements and new features over its predecessors. PHP is responsible for processing dynamic content on your website.
• PHP-FPM: A process manager.
• Composer: A dependency manager for PHP. It simplifies the process of managing external libraries and packages required by your PHP applications.
• Certbot: A tool that automates the process of obtaining and installing SSL/TLS certificates from Let’s Encrypt, enabling secure HTTPS connections to your website.

The Installation Process

The following commands, executed in your server’s terminal, will guide you through the setup:

1. Prepare the System:

   It’s always a good practice to start with an updated system. We’ll also install some essential packages that will be needed later.
   The DEBIAN_FRONTEND=noninteractive command use is for prevent any interactive prompts during package installations.

   sudo DEBIAN_FRONTEND=noninteractive
   sudo apt update -y
   sudo apt upgrade -y
   sudo apt install nginx wget build-essential curl lsb-release ca-certificates apt-transport-https software-properties-common -y
   

2. Enable Firewall Rules:

   For security, we’ll configure the firewall (ufw) to allow SSH access (for remote management) and traffic to Nginx.

   sudo ufw allow OpenSSH
   sudo ufw allow 'Nginx Full'
   

3. Add the PHP Repository:

   To install PHP 8.4, we’ll add a third-party repository that provides the latest PHP packages.

   sudo add-apt-repository ppa:ondrej/php -y
   sudo apt update
   

4. Install PHP 8.4 and Extensions:

   Now, we install PHP 8.4 along with a comprehensive set of commonly used extensions. These extensions provide additional functionality for your PHP applications, such as database connectivity (pgsql), image manipulation (gd, imagick), and more.

   sudo apt install php8.4 php8.4-fpm php8.4-common php8.4-pgsql php8.4-xml php8.4-xmlrpc php8.4-curl php8.4-gd php8.4-imagick php8.4-cli php8.4-dev php8.4-imap php8.4-mbstring php8.4-opcache php8.4-soap php8.4-zip php8.4-intl php8.4-bcmath unzip -y
   

5. Install Composer:

   Composer is essential for modern PHP development. This command downloads the Composer installer and places it in a system-wide accessible location.

   curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/bin --filename=composer
   

6. Install Certbot:

   We’ll use Snap, a package manager, to install Certbot. This ensures we have the latest version. First remove any existing apt version of Certbot.

   sudo snap install core; sudo snap refresh core
   sudo apt-get remove certbot
   sudo snap install --classic certbot
   sudo ln -s /snap/bin/certbot /usr/bin/certbot
   

Why This Approach?

This method prioritizes a clean and efficient installation. By using the ondrej/php PPA, you gain access to well-maintained PHP packages. The inclusion of a wide range of PHP extensions ensures that you have the necessary tools for most web application requirements. Using Snap for Certbot ensures you have the most up-to-date version for managing your SSL/TLS certificates.

Further Steps
After, those steps, you can configure Nginx to work with PHP, this configuration will depend on your specific application requirements.
Also, you’ll use Certbot to obtain and install your SSL/TLS certificates, securing your website.
