#!/bin/bash
# Optional: Port forward example with socat (install via apt install socat)
#socat TCP-LISTEN:8080,fork TCP:localhost:8069 &
# Your Odoo command (example for Odoo 17)

#exec /path/to/odoo-bin -c /path/to/odoo.conf --addons-path=/path/to/addons -d your_db --workers=2

export PYTHONHOME=/usr/local  # Or remove if not required
exec /home/user/Software/odoo-17.0/venv/bin/python3 /home/user/Software/odoo-17.0/odoo-bin  --http-port=8070 -d casa17g4

Step 2: Create service

 user  vi /etc/systemd/system/odoo17.service
