To configure systemd to start Odoo, you need to perform the following steps:

1. As root, create a file called /lib/systemd/system/odoo.service, with the following contents:

    [Unit]
    Description=Odoo 11.0
    After=postgresql.service
    
    [Service]
    Type=simple
    User=odoo
    Group=odoo
    WorkingDirectory=/home/odoo/odoo-prod/project
    ExecStart=/home/odoo/odoo-prod/project/bin/start-odoo
    
    [Install]
    WantedBy=multi-user.target

2. As root, register the service:

    # systemctl enable odoo.service

3. As root, start the service:

    # service odoo start

4. To stop the service, you can run the following:

    # service odoo stop
