Issue
I'm able to run flask app within virtualenv /web_services/flask_api/flask_api like this:
gunicorn --workers=4 --bind=localhost:8000 --log-level=error app:app
But, when I try to run it as a service it's not working. Here's a post that I followed to create a .service config file:
https://blog.miguelgrinberg.com/post/running-a-flask-application-as-a-service-with-systemd
Here's how my web_service.service file looks like:
[Unit]
Description=Sample web service
After=network.target
[Service]
User=aaa.bbb
WorkingDirectory=/web_services/flask_api/flask_api
ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error web_service:app
Restart=always
[Install]
WantedBy=multi-user.target
After saving this file I did:
$ sudo systemctl daemon-reload
$ sudo systemctl start web_service
$ sudo systemctl enable web_service
systemctl | grep running is not displaying this api.
While checking status of this service, I'm getting this:
sudo systemctl status web_service
● web_service.service - Sample web service
Loaded: loaded (/etc/systemd/system/web_service.service; enabled; vendor preset: disabled)
Active: failed (Result: start-limit) since Mon 2020-06-01 16:15:15 EDT; 13s ago
Process: 1016 ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error web_service:app (code=exited, status=1/FAILURE)
Main PID: 1016 (code=exited, status=1/FAILURE)
Don't know what I'm missing here or doing wrong. Any help would be appreciated..
Solution
It got solved by changing:
ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error web_service:app
to
ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error app:app
