One-Click Odoo 18 Installation on Ubuntu 22.04: the Complete Guide

One-Click Odoo 18 Installation on Ubuntu 22.04: the Complete Guide

“I wish I could spin up Odoo with one command…”

Now you can. In this post you’ll learn how to drop a single shell script onto a fresh Ubuntu 22.04 (Jammy) server and walk away—five minutes later you’ll have a production-ready Odoo 18 stack (Python 3.12, PostgreSQL, Node 18, wkhtmltopdf 0.12.5, systemd service, log rotation) humming on the port of your choice.

🗺️ What you’ll find below

1. Why a script beats the manual method
2. Prerequisites & tested environment
3. The installer script (copy-paste ready)
4. Running it—literally one command
5. What the script does under the hood
6. Troubleshooting & common questions
7. Wrapping up

1 Why automate?

• Consistency – zero “works-on-my-laptop” surprises.
• Speed – 200+ manual keystrokes crushed into 1.
• Idempotence – re-run anytime to heal a half-broken install.
• Safety – the Odoo Linux user is system-scoped, no login shell by default.

2 Prerequisites

Need Ubuntu 24.04? Swap in Python 3.12 from the default repo and skip the legacy libssl1.1 step—the rest is identical.

3 The one-click installer

Create a file called install_odoo18_22.sh  (sudo nano install_odoo18_22.sh ) and paste the contents below.

(Feel free to add it to a gist or your Ansible repo later.)

Make it executable:

chmod +x install_odoo18_22.sh

4 Run it (the real “single click”)

sudo ./install_odoo18_22.sh --db-pass "ChangeMe!" --port 8069

Grab a coffee—the script:

1. Updates the OS.
2. Installs Python 3.12, Node 18, PostgreSQL 14, wkhtmltopdf 0.12.5.
3. Creates a non-login odoo18 system user.
4. Clones the Odoo 18 source and builds a virtual environment.
5. Drops a hardened odoo18.conf in /etc.
6. Registers a systemd service and starts it.

When you see “🎉 Odoo 18 is live”, point your browser to:

http://<SERVER-IP>:8069

and create your first database.

7 Wrapping up

With one script and one command you’ve provisioned a fully-functional Odoo 18 stack on Ubuntu 22.04—ready for production or dev play. Clone the script into your IaC pipeline, bake it into a custom AMI, or hand it to a teammate who “just needs Odoo” by lunchtime.

Happy automating—and happy selling with Odoo 18!
