how to make my python-flask website available 24*7 using nginx and gunicorn

How to configure gunicorn to make sure my python-flask website is available 24*7 ? The issue I am facing is: As soon I kill my terminal window, the website is no more reachable.

I am using rhel7.6 to host a website using python-flask. I have configured nginx as the web server and gunicorn as the application server.

. I will really appreciate if some one can help me in using/configuring gunicorn to make sure my website is available 24*7.

Please have some of my code as below:

[root@syed-dashboard-4 ~]# pwd
/root
[root@syed-dashboard-4 ~]#
[root@syed-dashboard-4 ~]# cat hello.py
#!/usr/bin/python

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
        return "Hello magentabox!"

#if __name__ == "__main__":
#        app.run(host='10.145.29.23',port=5000)

[root@syed-dashboard-4 ~]#
[root@syed-dashboard-4 ~]# gunicorn hello:app
[2019-07-17 10:34:11 +0000] [9346] [INFO] Starting gunicorn 19.9.0
[2019-07-17 10:34:11 +0000] [9346] [INFO] Listening at: http://127.0.0.1:8000 (9346)
[2019-07-17 10:34:11 +0000] [9346] [INFO] Using worker: sync
[2019-07-17 10:34:11 +0000] [9351] [INFO] Booting worker with pid: 9351

I am pretty new to web development and as I mentioned as soon I close the terminal, the website is no more reachable. I can share the nginx configuration logs as well if that helps fixing my issue. Thanks much.

You can use the supervisor. This is the professional way to run your server for 24*7. Please add below file in your supervisor config to run.

[program:your_project_name]
command=/home/virtualenvpath/your_env/bin/gunicorn --log-level debug run_apiengine:main_app --bind 0.0.0.0:5006 --workers 5 --worker-class gevent
stdout_logfile=/home/your_path_to_log/supervisor_stdout.log
stderr_logfile=/home/your_path_to_log/supervisor_stderr.log
user=your_user
autostart=true
autorestart=true
environment=PYTHONPATH="$PYTHONPATH:/home/path_to_your_project";OAUTHLIB_INSECURE_TRANSPORT='1';

Configure this in supervisor it will run for 24*7. And whenever your machine restarts it will auto start.

On Linux, you can start your app in a tmux session that you detach once you started your server.

# Create a new tmux session
tmux new -s server

# Start your gunicorn server
cd /path/to/app
gunicorn hello:app

# Detach the current tmux session using Ctrl - B + D

You can close your terminal and your server will still be running.
