- Starting a Gunicorn server: The basic command to start a Gunicorn server is:
gunicorn your_app_module:app
- Replace your_app_module with the name of the Python module where your Flask application object (app) is defined.
-
Specifying the number of worker processes: You can control the number of worker processes using the -w or --workers option. For example, to start the server with 4 worker processes, use:
gunicorn -w 4 your_app_module:app -
Setting the bind address and port: The -b or --bind option allows you to specify the address and port on which the server should bind. For example, to bind to localhost on port 8000, use:
gunicorn -b localhost:8000 your_app_module:app
- Logging options: Gunicorn provides various options to configure logging. For example, you can set the log level using the --log-level option. The available log levels are debug, info, warning, error, and critical. To set the log level to info, use:
- gunicorn --log-level info your_app_module:app
- Graceful shutdown: To gracefully shutdown the Gunicorn server, send a SIGTERM or SIGINT signal to the process. For example, you can use Ctrl+C in the terminal where the server is running to send the SIGINT signal and initiate a graceful shutdown.
