🚀 Introduction

In this lesson, you will install Django on your Ubuntu server, create your development environment, and run your first Django project online using your server’s IP address. By the end of the lesson, you will have two working pages:

• / → Success / Home page
• /about/ → Simple About page

This lesson is intentionally beginner-friendly, with detailed steps and a troubleshooting section based on real issues that learners often face.

🧰 1. Update Your Server & Install Required Tools

SSH into your server:

ssh youruser@your-server-ip

Update and install required packages:

sudo apt update && sudo apt upgrade -y
sudo apt install -y python3 python3-venv python3-pip git

Verify:

python3 --version
pip3 --version

---

📁 2. Create a Root Folder for All Django Projects

A good habit is to keep all your Django projects in one folder:

mkdir -p ~/django-projects
cd ~/django-projects

Create a new project folder:

mkdir lesson2_project
cd lesson2_project

---

🧪 3. Create & Activate a Python Virtual Environment

A virtual environment ensures every project has its own isolated dependencies:

python3 -m venv venv
source venv/bin/activate

You should now see:

(venv)

If you re-login later, reactivate with:

source ~/django-projects/lesson2_project/venv/bin/activate

---

🟢 4. Install Django

Inside the active venv:

pip install --upgrade pip
pip install django

Check version:

python -m django --version

---

🛠️ 5. Create Your Django Project

Use the name config for the base settings:

django-admin startproject config .

Now your folder contains:

manage.py  
config/  
venv/

---

🌐 6. Run Django on Your Server (Port 1011)

Django’s development server can run on any port.

We’ll use 1011:

python manage.py runserver 0.0.0.0:1011

Open in your browser:

http://YOUR_SERVER_IP:1011

You should see:

🚀 “The install worked successfully!”

---

🏗️ 7. Create Your First App

Every Django feature lives inside an app.

Create one called core:

python manage.py startapp core

---

🧩 8. Register the App

Open your settings:

nano config/settings.py

Find INSTALLED_APPS and add:

'core',

Save and exit.

---

✨ 9. Create Your First View (Home Page)

Open:

nano core/views.py

Add:

from django.http import HttpResponse

def hello(request):
    return HttpResponse("""
        <h1 style='text-align:center;color:#007bff;'>Success!</h1>
        <p style='text-align:center;'>I finished Lesson 2 in Django!</p>
        <p style='text-align:center;font-size:14px;color:gray;'>
        View generated by Webmaster and More's Django server.
        </p>
    """)

---

🌍 10. Add URLs for Your App

Create:

nano core/urls.py

Insert:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.hello, name='hello'),
]

Then connect it in config/urls.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('core.urls')),
]

---

📄 11. Create the /about/ Page

In core/views.py:

def about(request):
    return HttpResponse("""
        <div style='text-align:center;padding:40px;'>
            <h1 style='color:#0066ff;'>My Path to Full Stack</h1>
            <h3>This Django training will help me upgrade to Full Stack Developer.</h3>
            <p>Setting clear goals is the first step to achieving them. Keep pushing forward!</p>
            <p style='font-size:14px;color:gray;'>
                View generated by webmasterandmore's Django server.
            </p>
        </div>
    """)

Then add the URL:

path('about/', views.about, name='about'),

---

🖥️ 12. Visit Your Pages

Home page:

http://YOUR_SERVER_IP:1011/

About page:

http://YOUR_SERVER_IP:1011/about/

Both should work now.

---

🚑 Troubleshooting (Beginner-Friendly)

These are real errors you may encounter (and how to fix them).

---

❗ 1. Browser shows HTTPS error (ERR_SSL_PROTOCOL_ERROR)

Cause: You used https:// instead of http://.

Fix:
Use:

http://YOUR_SERVER_IP:1011

---

❗ 2. DisallowedHost at /

Error:

Invalid HTTP_HOST header …

Cause: You didn’t add your server IP to ALLOWED_HOSTS.

Fix:

ALLOWED_HOSTS = ['YOUR_SERVER_IP', 'localhost', '127.0.0.1']

---

❗ 3. Port already in use

Error:

Error: That port is already in use

Fix: Choose a different port:

python manage.py runserver 0.0.0.0:1012

Check used ports:

sudo ss -tulnp

---

❗ 4. favicon.ico 400 errors

Ignore these — browsers request /favicon.ico automatically.
