It offers a modular approach, allowing users to customize and integrate different modules according to their business needs.

Here are the steps to install Odoo on Ubuntu 20.04:

Step 1: Update System Packages

First, update the system package lists and upgrade the existing packages by running the following commands in the terminal:

sudo apt update
sudo apt upgrade

Step 2: Install Dependencies

Odoo requires several dependencies to be installed on the system. Install the required dependencies by running the following command:

Step 3: Create a System User for Odoo

Create a system user to run the Odoo service. Run the following command to create a new system user named 'odoo':

sudo adduser --system --home=/opt/odoo --group odoo

Step 4: Install and Configure PostgreSQL Database Server

Odoo requires a PostgreSQL database server to store its data. Install PostgreSQL by running the following command:

sudo apt install postgresql

After the installation, create a new PostgreSQL user for Odoo by running the following command:

Step 5: Install and Configure Odoo

Next, create a configuration file for Odoo. Use the following command to create the configuration file:

sudo nano /etc/odoo.conf

Copy and paste the following configuration into the file:

[options]
; This is the password that allows database operations:
admin_passwd = admin
db_host = False
db_port = False
db_user = odoo
db_password = False
addons_path = /opt/odoo/addons
logfile = /var/log/odoo/odoo.log

Save and exit the file. Provide your desired password for the 'admin_passwd' field.

Step 6: Set Up Odoo as a Systemd Service

Create a systemd service file to manage the Odoo service. Run the following command to create the service file:

sudo nano /etc/systemd/system/odoo.service

Copy and paste the following service definition into the file:

[Unit]

[Service]
# Ubuntu/Debian convention:

Save and exit the file.

Step 7: Start and Enable the Odoo Service

Start the Odoo service and enable it to start on system boot by running the following commands:
