# Script for installing Odoo on Ubuntu 20.04 LTS (could be used for other version too)
# Author: Henry Robert Muwanika
#-------------------------------------------------------------------------------
# This script will install Odoo on your Ubuntu 20.04 server. It can install multiple Odoo instances
# in one Ubuntu because of the different xmlrpc_ports
#-------------------------------------------------------------------------------
# crontab -e
# 43 6 * * * certbot renew --post-hook "systemctl reload nginx"
# Make a new file:
# sudo nano install_odoo_ubuntu.sh
# Place this content in it and then make the file executable:
# sudo chmod +x install_odoo_ubuntu.sh
# Execute the script to install Odoo:
# ./install_odoo_ubuntu.sh
