Deploy Django in AWS EC2

1. Setting up server

• Allow HTTP (Port 80), SSH (Port 22), HTTPS (Port 443) inbound traffic of your server.
• Save your server connection files in a secure location and connect through the SSH port of your server.
• Windows users follow this guide to connect using the Putty client.
• Once logged in run these commands to update the server ubuntu os in to the latest stable version.

sudo apt-get update

• Install following packages to the server.

sudo apt install python3-pip python3-dev python3-venv libpq-dev postgresql postgresql-contrib nginx gunicorn curl

• Then enable firewall for nginx and openssh(Optional).

sudo ufw enable
sudo ufw allow OpenSSH
sudo ufw allow 'Nginx Full'

2. Configuration for Github

• Install Github CLI

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
sudo apt update
sudo apt install gh

• Then upgrade CLI

sudo apt update
sudo apt install gh

• Add your Github to server(When generating tokens add a token with a limited amount of time).

gh auth login

• Finally clone your repository

git clone <YOUR-PROJECT-GIT>

3. Configuring Postgresql

• Open the psql terminal.

sudo -u postgres psql

• Execute following commands one at a time to create a db and a user.

CREATE DATABASE dbname;

CREATE USER user WITH ENCRYPTED PASSWORD 'pass';

GRANT ALL PRIVILEGES ON DATABASE dbname TO user;

4. Configuring environment(one time only)

• Open the cloned the repository and execute following commandsto install venv.

cd <YOUR-PROJECT-NAME>
python3 -m venv env
source env/bin/activate
pip install wheel gunicorn
pip install -r requirements.txt

• Add the .env file content to the server environment(Keep no spaces in variable value assigning) and restart shell.

sudo nano /etc/environment

• Then do the migrations for django.

python manage.py makemigrations
python manage.py migrate
python manage.py collectstatic

• Create a superuser to django.

python manage.py createsuperuser

5. Configuring Gunicorn

• Create a socket file for gunicorn.

sudo nano /etc/systemd/system/gunicorn.socket

• Add the content of the gunicorn.socket file to the editor window.
• Next configure the gunicorn.service file.

sudo nano /etc/systemd/system/gunicorn.service

• Add the content of the gunicorn.service file to the editor window with replacing necessary content.
• Run following to make gunicorn service start and enabled.

sudo systemctl start gunicorn.socket
sudo systemctl enable gunicorn.socket
sudo systemctl status gunicorn.socket

6. Configuring NGINX

• Create a seperate file for the project

sudo nano /etc/nginx/sites-available/<YOUR-PROJECT-NAME>

• Add the content of nginx file to the editor window after replacing the necessary content.
• Once your NGINX config is set up, make sure there are no syntax errors.

sudo nginx -t

• Next, create a soft link of your config file from sites-available to the sites-enabled directory.

sudo ln -s /etc/nginx/sites-available/<YOUR-PROJECT-NAME> /etc/nginx/sites-enabled

• Run following to make gunicorn service start and enabled.

sudo systemctl restart nginx

7. Automate Deployment

• Copy the deployment file(if available) to the root directory with other required files.

cp <YOUR-PROJECT-NAME>/deploy.sh .

• Then excute deployment.

/bin/sh deploy.sh
