Introduction

This repository contains the necessary files and instructions to set up two Arch Linux servers with a load balancer. Each server will run a Bash script that generates a static index.html file containing system information. The script is configured to run automatically every day at 05:00 using a systemd service and timer. The generated HTML document will be served with an nginx web server running on both droplets, secured with ufw. A load balancer will distribute traffic between the two servers to ensure high availability and scalability. [1]

Prerequisites

Before proceeding, ensure the following prerequisites are met:

1. Two Arch Linux DigitalOcean droplets with the tag web are set up.

2. A load balancer is configured to connect with the web tag.

3. Both servers have been updated and restarted:

sudo pacman -Syu --noconfirm
sudo reboot

4. The following files have been uploaded to both servers:

   a. serverSetup.sh

   b. generate_index

   c. generate_index.service

   d. generate_index.timer

Setup Instructions

Run the serverSetup.sh script on each server to complete the setup process.

Accessing the Web Servers

To access the web servers, navigate to the load balancer's IP address in a web browser. The load balancer will distribute traffic between the two servers. Optionally, you can access the individual servers by navigating to their respective IP addresses.
