Day 26 : Configuring an EC2 Instance as a Web Server with Nginx

Welcome to Day 26. Today, we will learn how to configure an EC2 instance as a web server using Nginx. In this lab, you will discover what User Data Scripts are and how they work.

What is User Data Script in AWS?

In AWS, User Data is a feature that allows you to automate the configuration of an Amazon EC2 instance when it is first launched. This process is commonly known as bootstrapping. Instead of manually logging into a server via SSH to install software or change settings, you provide a script (or other data) during the launch process, and AWS executes it for you.

Common Use Cases

• Software Installation: Installing web servers (Nginx, Apache), databases, or runtime environments (Python, Node.js).

• Updates: Running apt-get update or yum update to ensure the OS has the latest security patches.

• Configuration: Setting environment variables, creating local users, or downloading application code from GitHub or S3.

• Service Management: Starting and enabling services so they survive a reboot.

#!/bin/bash

sudo apt update -y

sudo apt upgrade -y

sudo apt install nginx -y

sudo systemctl start nginx

sudo systemctl enable nginx
