Step-by-Step Guide to Hosting Django on EC2

Step 1: Create an EC2 Instance
Head over to AWS EC2 and spin up a new instance. Choose the Ubuntu AMI, configure your instance type, security groups, and launch your virtual server.

Step 2: SSH into the EC2 Instance
Access your instance securely using SSH:

ssh -i your_key.pem ubuntu@your_ec2_public_ip

Once connected, run:

sudo apt-get update -y && sudo apt-get upgrade -y

to ensure your instance is up-to-date.

Step 3: Set Up Your Environment

1. Clone your Django application repository:

git clone your_repo_url

2. Install Python's package manager, pip:

sudo apt install python3-pip

3. Install the virtual environment module:

sudo apt install python3.12-venv

4. Create a virtual environment:

python3 -m venv your_env_name

5. Activate your virtual environment:

source your_env_name/bin/activate

6. Install your app's dependencies:

pip install -r requirements.txt

Step 4: Database and Migrations
Set up a PostgreSQL database on AWS RDS, configure inbound rules in your EC2 security group, and add the details to your .env file. Then, run:

python3 manage.py makemigrations
python3 manage.py migrate

Step 5: Install and Configure Nginx

1. Install Nginx:

sudo apt install nginx -y

2. Enable and start Nginx:

sudo systemctl enable nginx
sudo systemctl start nginx

3. Configure Nginx by creating a new file:

sudo nano /etc/nginx/sites-available/your_project

Paste this config:

server {
    listen 80;
    server_name your_domain_or_public_ip;

    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location /static/ {
        alias /path/to/static/files/;
    }

    location /media/ {
        alias /path/to/media/files/;
    }
}

4. Enable your configuration:

sudo ln -s /etc/nginx/sites-available/your_project /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx

Step 6: Serve Static Files on S3
Set up an S3 bucket to store your static and media files. Run this command to collect static files:

python3 manage.py collectstatic

Step 7: Set Up Gunicorn
Install Gunicorn:

pip install gunicorn

Serve your app:

gunicorn --bind 0.0.0.0:8000 your_project.wsgi:application

Step 8: Update EC2 Inbound Rules
Add your application’s port in AWS EC2 inbound rules to ensure traffic is allowed.

Step 9: Access Your Site
Visit your EC2 instance's public IP in the browser, and your Django application is live!
