Odoo Install Script for Ubuntu 24.04

This script automates the installation of Odoo 18.0 (Community or Enterprise) on Ubuntu 24.04, including:

• Python virtual environment setup (required by Ubuntu 24.04)
• PostgreSQL 16 installation
• Nginx reverse proxy configuration
• SSL setup with Certbot (Let's Encrypt)
• Systemd service for Odoo (replacing legacy SysV init scripts for reliability and auto-restart)

---

⚡️ About This Script

This script is based on the install script from Yenthe Van Ginneken and improved to work on Ubuntu 24.04 with venv, as Ubuntu 24.04 enforces packages to be installed within a Python virtual environment.

Why Systemd Instead of SysV Init?

On Ubuntu 24.04, systemd is the native and recommended init system. The original Yenthe script used SysV init scripts, but this approach is now considered legacy and problematic:

1. SysV is legacy; systemd is standard

   • SysV init scripts are older, sequential, and fragile.
   • Modern Ubuntu uses systemd natively — it's faster, parallel, and smarter.
   • On Ubuntu 24.04, relying on SysV is like trying to run diesel in a Tesla. It "works," but not properly.

2. SysV can't monitor or auto-restart Odoo

   • If Odoo crashes, SysV won't bring it back.
   • Systemd with Restart=always will automatically restart Odoo if it crashes or gets killed (e.g., by out-of-memory).

3. Systemd improves reliability

   • We observed more frequent system crashes and unreliable Odoo restarts with SysV on Ubuntu 24.04.
   • Systemd provides better logging, monitoring, and service management.

This script creates a robust systemd service for Odoo, ensuring it starts at boot, restarts on failure, and integrates with modern Ubuntu service management tools.
