How to Implement Nginx and Caddy: Simple and Full Configurations with Headers for Educational Platforms in 2025

🔍 Introduction: Power Education with Caddy in 2025

Caddy, an open-source web server written in Go, simplifies web hosting with automatic HTTPS, HTTP/3 support, and an intuitive Caddyfile configuration. With 30% adoption among modern web servers (Stack Overflow), Caddy is ideal for deploying educational platforms on Amazon EC2 Ubuntu, leveraging India’s 35% EdTech growth (NASSCOM). This guide covers simple and full Caddyfile configurations, including security headers, to deploy a Next.js frontend and Python/FastAPI backend for a course dashboard in the ap-south-1 region at ₹0.80/hour. Let’s revolutionize learning!

🚀 Step-by-Step: Deploying Caddy on EC2 Ubuntu

Caddy serves as a reverse proxy for the backend and a static file server for the frontend, with automatic TLS.

1. Launch EC2 Instance

Log in to the AWS Console, go to EC2, and click “Launch Instance”:

  • Name: Caddy-Education

  • AMI: Ubuntu Server 20.04 LTS

  • Type: t2.micro

  • Key Pair: Create caddy-key.pem and use chmod 400 caddy-key.pem

  • Network: Enable public IP, allow SSH (22), HTTP (80), HTTPS (443)

  • Storage: 8 GB SSD

Note the public IP (e.g., 54.123.45.67).


2. Install Caddy

SSH into the server:

bash

CopyEdit

ssh -i caddy-key.pem ubuntu@<your-ec2-public-ip> sudo apt update && sudo apt upgrade -y

Install Caddy:

bash

CopyEdit

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl -1sLf "https://dl.cloudsmith.io/public/caddy/stable/gpg.key" | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg curl -1sLf "https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt" | sudo tee /etc/apt/sources.list.d/caddy-stable.list sudo apt update && sudo apt install caddy


3. Set Up Python Backend (FastAPI)

Install Python and dependencies:

bash

CopyEdit

sudo apt install -y python3 python3-pip mkdir edu-backend && cd edu-backend pip install fastapi uvicorn pip freeze > requirements.txt

Create main.py:

python

CopyEdit

from fastapi import FastAPI app = FastAPI() @app.get("/courses") async def get_courses(): return [{"id": 1, "title": "Python 101"}, {"id": 2, "title": "Math 101"}]

Run:

bash

CopyEdit

uvicorn main:app --host 0.0.0.0 --port 8000


4. Set Up Next.js Frontend

Install Node.js:

bash

CopyEdit

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash - sudo apt install -y nodejs

Create frontend locally:

bash

CopyEdit

npx create-next-app@latest edu-frontend cd edu-frontend npm install axios

Edit pages/index.js:

jsx

CopyEdit

import { useState, useEffect } from "react"; import axios from "axios"; export default function Home() { const [courses, setCourses] = useState([]); useEffect(() => { axios.get("http://yourdomain.com/api/courses") .then(res => setCourses(res.data)); }, []); return ( <div> <h1>Course Dashboard</h1> <ul> {courses.map(c => <li key={c.id}>{c.title}</li>)} </ul> </div> ); }

Build and export:

bash

CopyEdit

npm run build && npm run export


5. Simple Caddyfile Configuration

Edit /etc/caddy/Caddyfile:

caddy

CopyEdit

yourdomain.com { reverse_proxy /api/* localhost:8000 root * /home/ubuntu/edu-frontend/out file_server }

Transfer frontend files:

bash

CopyEdit

scp -i caddy-key.pem -r out ubuntu@<your-ec2-ip>:/home/ubuntu/edu-frontend/ sudo systemctl reload caddy


6. Full Caddyfile with Security Headers

Edit /etc/caddy/Caddyfile:

caddy

CopyEdit

{ auto_https servers { trusted_proxies static private_ranges } } yourdomain.com { encode zstd gzip header { Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" X-Content-Type-Options "nosniff" X-Frame-Options "DENY" X-XSS-Protection "1; mode=block" Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'; connect-src 'self' http://yourdomain.com/api/*;" Referrer-Policy "strict-origin-when-cross-origin" Permissions-Policy "geolocation=(), camera=(), microphone=()" -Server } reverse_proxy /api/* localhost:8000 { header_up X-Real-IP {remote} } root * /home/ubuntu/edu-frontend/out file_server try_files {path} /index.html }

Reload Caddy:

bash

CopyEdit

sudo systemctl reload caddy
