Before You Start

What we are building and what you need

The Journey of Every Web Request

User Types URL → Browser → DNS → Router → Your Server → Page Loads

What is a home server?

A server is just a computer that provides a service to other computers. Your home server will run a program called Apache that listens for requests and sends back your website files. It is not special hardware — it is a normal computer running server software.

What You Need

A computer with Linux installed
Internet connection (Ethernet preferred)
Access to your router's admin panel
About 1 hour

What You Will Have

A live website on the internet
Your own domain name (free)
Encrypted HTTPS connection
Full control over your site

I understand this is a chain of steps. If one breaks, the site stops.

1

Prepare Your Linux Machine

Know your address and update your system

Why this matters

Your server needs a consistent local IP address so your router always knows where to send traffic. We also update the system so we install current, secure software.

Step 1A: Find your local IP address

Open a terminal on your Linux machine and run:

ip addr show

Look for the inet line under your network adapter (usually eth0 for wired, wlan0 for wireless)
It will look like 192.168.1.50 or 192.168.0.45
Write this number down. We need it for the router later.

Step 1B: Update your system

sudo apt update && sudo apt upgrade -y

apt update refreshes the list of available software
apt upgrade installs the latest versions
-y automatically answers "yes" to prompts
This may take 5–10 minutes if your system is outdated

⚠️ Stuck here?

If sudo asks for a password, type your user password (characters won't show on screen). If you get "command not found," make sure you are on a Debian/Ubuntu-based system. For other Linux distributions, the package manager will be different (e.g., dnf for Fedora).

I have my local IP written down and my system is updated.

2

Install Apache

The software that serves your website

What is Apache?

Apache HTTP Server is a program that runs in the background, listens for incoming requests on port 80, finds the right file on your computer, and sends it back to the visitor's browser. It is one of the most widely used web servers in the world.

Install Apache

sudo apt install apache2 -y

This downloads and installs Apache and its dependencies
After installation, Apache starts automatically
It is now listening on port 80 inside your machine

Verify Apache is running

sudo systemctl status apache2

Look for active (running) in green
systemctl is the command Linux uses to manage background services
If it says inactive, run: sudo systemctl start apache2

Test locally

curl http://localhost

curl is a command-line tool that fetches web pages
You should see HTML output — the Apache default page
This confirms Apache is answering requests from the same machine

Apache is installed, running, and I saw the default page with curl.

3

Create Your Website

Replace the default page with your own content

Where do website files live?

Apache's default web root (the folder it looks in for files) is /var/www/html/. When someone visits your site, Apache looks for index.html in that folder and sends it.

Remove the placeholder

sudo rm /var/www/html/index.html

Create your own homepage

sudo nano /var/www/html/index.html

nano is a simple text editor inside the terminal
Since /var/www/html/ is a system folder, you need sudo to write to it

Type this inside nano:

<!DOCTYPE html> <html> <head> <title>My Home Server</title> </head> <body> <h1>This site is served from my living room</h1> <p>Built with Apache on Linux.</p> </body> </html>

Press Ctrl+O to save (then press Enter to confirm)
Press Ctrl+X to exit nano

Test from another device on your Wi-Fi

On your phone or another computer connected to the same network, open a browser and go to:

http://192.168.1.50

(Replace with your actual local IP from Step 1)

What just happened?

Your other device asked your Linux machine for a web page. Apache received the request, found index.html, and sent it back. This works only inside your home right now. The internet cannot reach it yet.

I see my custom page when I visit my local IP from another device.

4

Configure the Firewall

Let Apache through the Linux firewall

What is a firewall?

Your Linux machine has a built-in gatekeeper called UFW (Uncomplicated Firewall). By default, it may block incoming requests. We need to tell it: "Allow web traffic on ports 80 and 443."

Check if the firewall is active

sudo ufw status

If it says Status: inactive, the firewall is not running. You can skip to the next step, but enabling it is recommended.
If it says Status: active, continue below.

Allow Apache through the firewall

sudo ufw allow 'Apache Full'

'Apache Full' is a pre-built profile that opens both port 80 (HTTP) and port 443 (HTTPS)
UFW knows which ports Apache needs, so you don't have to memorize the numbers yet

Enable the firewall (if it was off)

sudo ufw enable

Type y and press Enter when it warns you about disrupting connections
SSH (port 22) is usually already allowed if you are connected remotely

Verify the rules

sudo ufw status

You should see rules for Apache Full, and possibly SSH.

My firewall allows Apache on ports 80 and 443.

5

Find Your Public IP

The address the internet sees

Two different addresses

You have a local IP (like 192.168.1.50) that only works inside your house. Your router has a public IP that the entire internet sees. When someone visits your site from another city, they use your public IP.

Get your public IP

curl ifconfig.me

This asks an external service to tell you what IP address it sees from your connection
It will look different from your local IP — something like 203.0.113.45
Write this number down.

Important: Your public IP changes

Most home internet plans give you a dynamic IP — it changes periodically. That is why we will set up Dynamic DNS in Step 7. But for now, we just need to know what it is today.

I have my public IP written down.

6

Port Forwarding on Your Router

The most critical step — open the door from the internet

What is port forwarding?

Your router is the gatekeeper. It has one public IP, but many devices inside your home. When a request from the internet arrives on port 80, the router needs a rule that says: "Send this to the Linux server at 192.168.1.50." Without this rule, the request dies at the router.

Log into your router

Open a browser and go to http://192.168.1.1 or http://192.168.0.1
If neither works, check the sticker on your router for the admin IP
Enter the admin username and password (also on the sticker, or set by you)

Find the Port Forwarding section

Look for one of these names in your router menu:

Port Forwarding

Virtual Servers

NAT / Gaming

Applications

Create two forwarding rules

Name	External Port	Internal IP	Internal Port	Protocol
Apache-HTTP	80	192.168.1.50	80	TCP
Apache-HTTPS	443	192.168.1.50	443	TCP

Replace 192.168.1.50 with your actual local IP from Step 1.

External Port: The port the internet sees (80 for HTTP, 443 for HTTPS)
Internal IP: Your Linux machine's local address
Internal Port: Same as external port (80 and 443)
Protocol: TCP — the standard for web traffic
Save or Apply the rules. Some routers require a reboot.

Test from outside your network

Use your phone with Wi-Fi turned OFF (use cellular data) or ask a friend:

http://YOUR_PUBLIC_IP

Replace with your actual public IP from Step 5.

If you see your page, the chain is complete

Internet → Public IP → Router → Port Forward → Linux → Apache → Your File. Every link works.

⚠️ It doesn't work?

Double-check the local IP — did it change? Set a static IP or DHCP reservation in your router.
Check your ISP — some block port 80. Try port 8080 externally and forward to 80 internally.
Firewall on router? Some routers have a separate firewall. Look for "SPI Firewall" or "Access Restrictions."
Wrong protocol? Some routers require you to select TCP/UDP. Choose TCP only.

I can see my website from a phone on cellular data (or from outside my network).

Dynamic DNS

Give your server a name that never changes

The problem with IP addresses

Your public IP changes. If you give someone your IP today, it might be wrong tomorrow. Dynamic DNS gives you a free domain name (like yourname.duckdns.org) that automatically updates to point to your current IP.

Step 7A: Sign up at DuckDNS

Go to duckdns.org
Sign in with Google, GitHub, or Reddit
Create a subdomain: yourname.duckdns.org
Copy your token (a long string of letters and numbers)

Step 7B: Create the update script

mkdir ~/duckdns && cd ~/duckdns

nano duck.sh

Type this inside nano (replace YOURNAME and YOUR_TOKEN):

echo url="https://www.duckdns.org/update?domains=YOURNAME&token=YOUR_TOKEN&ip=" | curl -k -o ~/duckdns/duck.log -K -

Press Ctrl+O, then Enter, then Ctrl+X

Step 7C: Make it executable and test

            
chmod 700 duck.sh
./duck.sh
cat duck.log
        

chmod 700 makes the script runnable by only you
./duck.sh runs it
cat duck.log shows the result — it should say OK

Step 7D: Automate it

crontab -e

If it asks which editor to use, choose nano (option 1)
Add this line at the bottom:

*/5 * * * * ~/duckdns/duck.sh >/dev/null 2>&1

This means: "Run the script every 5 minutes, silently."
Press Ctrl+O, Enter, Ctrl+X

Test your domain

Wait 2–3 minutes, then visit:

http://yourname.duckdns.org

Replace with your actual DuckDNS subdomain.

My DuckDNS domain loads my website.

Add HTTPS with Let's Encrypt

Encrypt your connection for free

HTTP vs. HTTPS

	Port 80 — HTTP	Port 443 — HTTPS
Security	Unencrypted	Encrypted (TLS/SSL)
Data	Readable by anyone intercepting	Private between browser & server
Browser	No padlock	Shows padlock icon
Required for	Testing only	Logins, payments, SEO, production

Install Certbot

sudo apt install certbot python3-certbot-apache -y

certbot is the tool that gets free certificates from Let's Encrypt
python3-certbot-apache is the plugin that configures Apache automatically

Get the certificate

sudo certbot --apache -d yourname.duckdns.org

Replace yourname.duckdns.org with your actual DuckDNS domain
Enter your email when prompted (for renewal notices)
Agree to the terms
Choose whether to share your email (optional)
When asked about redirecting HTTP to HTTPS, choose 2: Redirect

What Certbot does automatically

Proves you own the domain by connecting to it
Downloads an SSL certificate
Configures Apache to use the certificate on port 443
Sets up automatic renewal (certificates expire every 90 days)
Creates an HTTP→HTTPS redirect

Verify HTTPS

Visit your site with https://:

https://yourname.duckdns.org

You should see a padlock icon in the browser address bar
Clicking the padlock should say "Connection is secure"
HTTP requests should automatically redirect to HTTPS

Test automatic renewal

sudo certbot renew --dry-run

This simulates renewal without actually changing anything
If it says success, you are set for life — Certbot handles the rest

My site loads with HTTPS and shows a padlock.
