How to look Gunicorn logs when it running?

Question

I deployed a Flask application to a VPS, and using Gunicorn as a web server. And I running the Gunicorn server using this command:

gunicorn --bind=0.0.0.0 run:app --access-logfile '-'

With the command I can see the log running. But after I closed my terminal session, I want to see the running logs again.

In Heroku I can use heroku logs -t to do that, any similar way to see it on Gunicorn..?

You need to set up the supervisor. Supervisor keeps your server running mode and saves your log. setup the supervisor file below and then you can see the logs:

[program:your_project_name]
command=/home/your_virualenv/bin/gunicorn --log-level debug 
run_apiengine:main_app --bind 0.0.0.0:5007 --workers 2 --worker-class gevent
directory=your_project_directory
stdout_logfile= your_log_folder_path/supervisor_stdout.log
stderr_logfile= your_log_folder_path/supervisor_stderr.log
user=your_user
autostart=true
PYTHONPATH="$PYTHONPATH:your_python_path";OAUTHLIB_INSECURE_TRANSPORT='1';
