How to access odoo11 after installation:

1. For demonstration purposes, I will use two virtual machines: one as the "frontend server" for deploying the application, and the other for installing the PostgreSQL database and storing database data, referred to as the "backend server." Reminder: Ensure the server has a fixed IP address; otherwise, the installation may be interrupted due to address changes. 2. Configure the backend server. We start with the backend server, where PostgreSQL and the database will be installed. Open a terminal on the backend server and run the command: Create a PostgreSQL user, ensuring the username matches the one used by Odoo on the frontend server. In my example, the username is odoo11.
