 user  ~  vi /usr/local/bin/odoo-start.sh  
#!/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  
[Unit]
Description=Odoo 17 Service
After=network.target postgresql.service

[Service]
Type=simple
User=user
Group=user
WorkingDirectory=/home/user/Software/odoo-17.0
ExecStart=/usr/local/bin/odoo-start.sh
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload 

sudo systemctl reset-failed odoo17 

sudo systemctl start odoo17

sudo journalctl -u odoo17 -e #  See error

sudo journalctl -u odoo17 -f #  See live 

 

Step 4: Set it for boot

systemctl list-unit-files --type=service --state=enabled | grep odoo

sudo systemctl enable odoo17

systemctl list-unit-files --type=service --state=enabled | grep odoo

 

sudo systemctl disable odoo17  # disable from boot list
