Interpretation of Gunicorn's application scenarios in frameworks such as Django and Flask requires specific code examples
Abstract: Gunicorn (Green Unicorn) is a Python web server container that is widely used Applied to Django, Flask and other frameworks. This article will explain to readers the application scenarios of Gunicorn in these frameworks and provide corresponding code examples.
Here is a simple example showing how to use Gunicorn in a Django project:
# myproject/wsgi.py import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings') application = get_wsgi_application()
The command to start the Gunicorn service is as follows:
gunicorn myproject.wsgi:application
The following is a simple example showing how to use Gunicorn in a Flask project:
# app.py from flask import Flask app = Flask(__name__) @app.route('/') def hello(): return "Hello, World!" if __name__ == '__main__': app.run()
The command to start the Gunicorn service is as follows:
gunicorn app:app
# gunicorn_config.py bind = '0.0.0.0:8000' workers = 4 worker_class = 'sync' loglevel = 'info' errorlog = '/path/to/error.log' accesslog = '/path/to/access.log'
When starting the Gunicorn service, you can configure it by specifying the configuration file:
gunicorn -c gunicorn_config.py myproject.wsgi:application
