Now we're going to define the service to run this script:
cd /lib/systemd/system/
sudo nano picap.serviceThe service definition must be on the /lib/systemd/system folder. Our service is going to be called "picap.service":
[Unit]
Description=Picap Service
After=multi-user.target
[Service]
Type=simple
ExecStart=/usr/bin/python /home/pi/PiCapExamples/Python/picap-datastream-osc-py/datastream-osc.py -h 192.168.0.52
Restart=on-abort
[Install]
WantedBy=multi-user.target
Now that we have our service we need to activate it:
sudo chmod 644 /lib/systemd/system/picap.service
chmod +x /home/pi/PiCapExamples/Python/picap-datastream-osc-py/datastream-osc.py
sudo systemctl daemon-reload
sudo systemctl enable picap.service
sudo systemctl start picap.serviceFor every change that we do on the /lib/systemd/system folder we need to execute a daemon-reload (third line of previous code). If you want to check the status of the service, you can execute:
sudo systemctl status picap.service
In general:
sudo systemctl status picap.service
sudo systemctl start picap.service
sudo systemctl stop picap.service
sudo journalctl -f -u picap.service
