This guide explains a basic configuration of NGINX on your EC2 instance to serve traffic on ports 80 / 443.

Prerequisites

  • EC2 instance running Ubuntu, AlmaLinux, or Amazon Linux

  • Administrative (sudo) access

  • A web application, and the port it is hosted on (YOUR_APP_PORT)

Enable Firewall Access

  1. Navigate to your Space in the Spinup portal

  2. Open the Firewall tab

  3. Add rules allowing traffic to ports 80 and 443.

Installation

Ubuntu

sudo apt update && sudo apt install nginx

AlmaLinux/Amazon Linux

sudo dnf install nginx sudo setsebool -P httpd_can_network_connect 1

SSL Certificate Setup

Generate a self-signed certificate for backend HTTPS:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \ -keyout /etc/ssl/private/nginx-selfsigned.key \ -out /etc/ssl/certs/nginx-selfsigned.crt

NGINX Configuration

Create /etc/nginx/conf.d/app.conf:

Replace YOUR_APP_PORT with your application's port number.

Enable and Start NGINX

Verification

Check that NGINX is running:


From a web browser, attempt to connect to http://YOUR_IP and https://YOUR_IP. If you see your web application, you are all set!
