Preparing the host system
Odoo is usually deployed on Debian-based Linux systems. Ubuntu is a popular choice, and the latest long-term support (LTS) version is 20.04 Focal Fossa.
Other Linux distributions can also be used. The CentOS/Red Hat Enterprise Linux (RHEL) system is also popular in corporate circles.
The installation process requires elevated access, using the root superuser or the sudo command. When using a Debian distribution, the default login is root, which has administration access, and the command prompt shows #. On Ubuntu systems, the root account is disabled. Instead, the initial user is configured during the installation process and is a sudoer, meaning that the user is allowed to use the sudo command to elevate access and run commands with the root privileges.
Before starting the Odoo installation, the host system dependencies must be installed, and a specific user should be created to run the Odoo service.
