Odoo ERP Community Edition is installed during VPS provisioning. You finalize the setup by using the web-based installer.
Open the Odoo setup wizard
In your browser, go to:
http://YOUR_PUBLIC_IP:8069
The initial screen lets you:
Create a new database
Or restore an existing database backup
You can also choose whether to load demo data, which is useful for testing features.
Complete the initial configuration
Follow the prompts in the wizard to set your master password, database name, and admin credentials.
After this, Odoo will create the database and redirect you to the main dashboard.
For modules, integrations, and more advanced configuration, see the official Odoo documentation.
