# Script for installing Odoo on Debian 10.0 (could be used for other version too)
# Authors: Yenthe Van Ginneken, César Cordero Rodríguez
# Maintainers: Yenthe Van Ginneken, César Cordero Rodríguez
#-------------------------------------------------------------------------------
# This script will install Odoo on your Debian 10.0 server. It can install multiple Odoo instances
# in one Debian because of the different xmlrpc_ports
#-------------------------------------------------------------------------------
# Make a new file:
# sudo nano odoo-install.sh
# Place this content in it and then make the file executable:
# sudo chmod +x odoo-install.sh
# Execute the script to install Odoo:
# ./odoo-install
