cannot not get app.py to run as a service

[radiorusso]

I have been trying to get your sensor data monitoring program to run but have run into a road block. The app script wont run as a service. The path is correct and the script has be set to be executable. I get an 203 error here is what happens when I check the service pi@raspberrypi:~/sensor-data-monitoring-grafana $ pi@raspberrypi:~/sensor-data-monitoring-grafana $ sudo systemctl daemon-reload pi@raspberrypi:~/sensor-data-monitoring-grafana $ sudo systemctl enable sensor-flask.service --now pi@raspberrypi:~/sensor-data-monitoring-grafana $ systemctl status sensor-flask.service ● sensor-flask.service - A service that will keep my python app running in the background Loaded: loaded (/etc/systemd/system/sensor-flask.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2024-10-25 13:11:13 EDT; 17s ago Process: 18272 ExecStart=/usr/lib/python3 /usr/local/bin/app.py (code=exited, status=203/EXEC) Main PID: 18272 (code=exited, status=203/EXEC)

Also what does Change is the ExecStart flag Where do I go from here ?? Thanks in advance

Hi @radiorusso,

Thank you for reporting this issue.

It looks like an issue related to the path, or permissions.

Make sure that the python exec path is correct

which python3

If the path differs (e.g., /usr/bin/python3), update ExecStart accordingly.

Ensure that app.py is executable:

sudo chmod +x /usr/local/bin/app.py

After making changes, reload systemd and restart the service:

sudo systemctl daemon-reload
sudo systemctl restart sensor-flask.service

Hope it helps!

FYI

I have just released a Dockerized version of this project (see https://github.com/tonypowa/sensor-data-monitoring-grafana/blob/main/README.md). With Docker there is no need to create a service. You might want to try if that solves the issue.

If you still want to access the files of the old version, checkout the old version:

• git checkout tags/v1.0-old-version
