Gunicorn과 Nginx를 사용하여 확장 가능한 Django 애플리케이션 구축

sudo apt install python3 python3-pip nginx 

source environment_name/bin/activate   # use name created above "environment_name"

pip install django
pip install gunicorn

// or directly install both
pip install django gunicorn

django-admin startproject myproject      # use any name "myproject"

nano gunicorn_conf.py  # use any name but using same better "gunicorn_conf.py"

import multiprocessing

bind = '127.0.0.1:8000' # Django running port/link
workers = multiprocessing.cpu_count() * 2 + 1

cd myproject   # navigate to Django Project "myproject"

gunicorn myapp.wsgi:application -c ../gunicorn_conf.py  # here myapp is myproject

# here "myapp" is a Django project name, and at last gunicorn_conf.py is a gunicorn configuration file which created above/before.

# to open vs code from terminal

# example code
ALLOWED_HOSTS = ['localhost', '0.0.0.0', '127.0.0.1'] # use IP address here

ifconfig

sudo nano /etc/nginx/sites-available/myapp       # use any name "myapp"

# better use vs code instead of nano

sudo ufw allow 'Nginx Full'

sudo systemctl start nginx
