2. System Requirements and Prerequisites | Getting Started: Installation and Basic Configuration | Mastering Nginx: A Beginner's Guide to High-Performance Web Servers

Before diving headfirst into Nginx installation, it's crucial to understand the environment your web server will operate within. While Nginx is known for its lightweight nature and efficiency, there are a few fundamental system requirements and prerequisites to be aware of. These will ensure a smooth setup and optimal performance right from the start.

Here's what you'll need to consider:

Operating System: Nginx is highly portable and runs on a wide range of Unix-like operating systems. The most common and well-supported platforms include:

Linux: Distributions like Ubuntu, Debian, CentOS, RHEL, and Fedora are excellent choices. Nginx has robust support and is often pre-packaged in their repositories.

FreeBSD: Another popular and robust Unix-like operating system where Nginx performs admirably.

macOS: While often used for development, Nginx can also be installed and run on macOS.

Windows: Nginx also provides a Windows binary, though its primary strength lies in Unix-like environments.

Recommendation: For production environments, a stable Linux distribution is generally recommended due to its maturity, wide community support, and extensive tooling.

Hardware Resources: Nginx is famously resource-efficient. However, the exact requirements depend on the scale of your operation.

CPU: Even a single-core CPU can suffice for basic setups. For high-traffic sites, more cores will improve concurrent connection handling.

RAM: Nginx itself consumes very little memory. A few hundred megabytes should be plenty for the Nginx process alone. However, remember that your applications (e.g., PHP-FPM, Node.js) will also require RAM, so factor that in.

Disk Space: Minimal disk space is required for Nginx itself. You'll need more for your website's files, logs, and any operating system necessities.

Network Connectivity: A stable internet connection is obviously essential for a web server to serve content. Ensure your server has a static IP address or is configured to receive one.

Root or Sudo Privileges: Installing Nginx and modifying its configuration files typically requires administrative privileges. You'll need to be logged in as the root user or have the ability to use sudo.

Package Manager: Most operating systems come with a package manager (like apt for Debian/Ubuntu, yum/dnf for CentOS/Fedora). We'll leverage these for the easiest and most robust installation methods.

Basic Command Line Familiarity: While this guide aims to be beginner-friendly, a basic understanding of navigating your server's file system and executing commands in the terminal will be very helpful.

Understanding these prerequisites will set you up for success as we move on to the actual installation process. It's like ensuring you have the right tools before starting to build!
