Step 1: Update Package Manager

              sudo apt-get update  

sudo apt-get upgrade -y

Step 2: Create an Odoo User

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

Step 3: Install PostgreSQL and Create an Odoo User for PostgreSQL

sudo apt install postgresql -y

sudo su – postgres -c "createuser -s odoo" 2> /dev/null || true

sudo chmod 700 -R /var/lib/postgresql/14/main/

sudo systemctl restart postgresql

Step 4: Installation of Python and Python PIP Dependencies

sudo apt-get install git python3 python3-pip build-essential wget python3-dev python3-venv python3-wheel libxslt-dev libzip-dev libldap2-dev libsasl2-dev python3-setuptools node-less libjpeg-dev gdebi -y

sudo apt-get install libpq-dev python3-dev libxml2-dev libxslt1-dev libldap2-dev libsasl2-dev libffi-dev python3-psutil python3-polib python3-dateutil python3-decorator python3-lxml python3-reportlab python3-pil python3-passlib python3-werkzeug python3-psycopg2 python3-pypdf2 python3-gevent -y

Step 5: Additional Packages Required

sudo apt-get install nodejs npm -y

sudo npm install -g rtlcss

Step 6: Installation of wkhtmltox

sudo apt-get install xfonts-75dpi xfonts-base -y

wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-2/wkhtmltox_0.12.6.1-2.jammy_amd64.deb

sudo dpkg -i wkhtmltox_0.12.6.1-2.jammy_amd64.deb

Step 7: Create a Log Directory and Provide Permissions

sudo mkdir /var/log/odoo

sudo chown odoo:odoo /var/log/odoo

Step 8: Installation of Odoo 16

sudo apt-get install git

sudo git clone https://www.github.com/odoo/odoo /opt/odoo/odoo-server -b 16.0 --depth 1

Step 9: Setup Required Permissions

sudo chown -R odoo:odoo /opt/odoo/

Step 10: Creation of a Server Configuration File

sudo touch /etc/odoo-server.conf

sudo su root -c "printf '[options] \n; This is the password that allows database operations:\n' | sudo tee /etc/odoo-server.conf"

sudo su root -c "printf 'admin_passwd = admin\n' | sudo tee /etc/odoo-server.conf"

sudo su root -c "printf 'xmlrpc_port = 9080\n' | sudo tee /etc/odoo-server.conf"

sudo su root -c "printf 'logfile = /var/log/odoo/odoo-server.log\n' | sudo tee /etc/odoo-server.conf"

sudo su root -c "printf 'addons_path=/opt/odoo/odoo-server/addons\n' | sudo tee /etc/odoo-server.conf"

vim /etc/odoo-server.conf

[DEFAULT]
addons_path = /opt/odoo/odoo-server/addons

Give the configuration file the appropriate permissions:

sudo chown odoo:odoo /etc/odoo-server.conf

sudo chmod 640 /etc/odoo-server.conf

we must switch to the Odoo user by executing the command below:

sudo su -l odoo -s /bin/bash

cd odoo-server 

python3 -m venv odoo-venv  

source odoo-venv/bin/activate 


pip3 install wheel 

pip3 install -r requirements.txt

Using the deactivate command will allow us to leave the virtual environment after installing Python dependencies:

deactivate

Step 11: Start the Odoo Instance

cd /opt/odoo/odoo-server

source odoo-venv/bin/activate

./odoo-bin -c /etc/odoo-server.conf

Step 12: Login and Access the Odoo Application

http://localhost:8069
