Install Odoo 16 on Ubuntu 20.04 LTS Server In 17 Easy Steps

ERP is fast-becoming an integral component of business management in most countries. One of the most widely used ERPs on the market, Odoo has the largest global installation base. The software is used by more than 7 million users worldwide, from startups to large enterprises. One of the best parts of Odoo is that it is free, open-source ERP software written in Python and Javascript.

Quickly then, let’s get down to business and understand the 16 easy steps to install Odoo in the Ubuntu 20.04 LTS server.

Step 1: First, We Install Ubuntu Essentials

As a first step, we will update our existing packages and enable a few Odoo dependency repositories.

sudo apt install software-properties-common -y
sudo add-apt-repository universe
# libpng12-0 dependency for wkhtmltopdf
sudo add-apt-repository ppa:linuxuprising/libpng12 -y

sudo add-apt-repository "deb http://mirrors.kernel.org/ubuntu/ xenial main"
sudo apt update
sudo apt upgrade -y

Step 2: Next We Install Postgresql Server

Odoo stores data in a PostgreSQL database. Postgresql 12 comes by default with Ubuntu 22.04, so we can install it using the following command. Odoo 16 is also compatible with Postgresql versions 13, 14, 15.

sudo apt install postgresql postgresql-server-dev-all -y
#Creating the ODOO PostgreSQL User
sudo su - postgres -c "createuser -s odoo16"

Step 3: Now Install Python Dependencies

#Installing Python 3 + pip3
sudo apt 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 xfonts-base xfonts-75dpi -y
sudo apt install libpng12-0 -y

#Installing nodeJS NPM and rtlcss for LTR support
sudo apt install nodejs npm -y
sudo npm install -g rtlcss
sudo npm install -g less
sudo npm install -g less-plugin-clean-css

Step 4: Install wkhtmltopdf

wkhtmltopdf converts html content into pdf format. Using the wkhtmltopdf package, Odoo generates the reports in html format and then converts them to pdf.

sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.focal_amd64.deb
sudo apt install ./wkhtmltox_0.12.5-1.focal_amd64.deb

Step 5: Then Create ODOO System User

sudo adduser --system --quiet --shell=/bin/bash --home=/opt/odoo --gecos 'ODOO' --group odoo
# The user should also be added to the sudo'ers group.
sudo adduser odoo sudo

Step 6: Let’s Create the Log Directory

The logs of our Odoo instance will be stored in this directory.

sudo mkdir /var/log/odoo
sudo chown odoo:odoo /var/log/odoo

Step 7: Cloning Odoo to Server 

It’s now time to get Odoo’s source code so that we can run it on our server.

sudo git clone --depth 1 --branch 16.0 https://github.com/odoo/odoo /opt/odoo/odoo16/server-addons

Step 8: Setup Python Virtual Environment

To install the Python packages needed for Odoo, we will use a Python virtual environment. In order to do that, let’s create and activate a python virtual environment.

sudo pip3 install virtualenv
cd /opt/odoo/odoo16
virtualenv odoo-venv or python3 -m venv odoo-venv
source odoo-venv/bin/activate

Step 9: Install Python Packages/Requirements

pip3 install -r /opt/odoo/odoo16/server-addons/requirements.txt
pip3 install psycopg2-binary pdfminer.six num2words ofxparse dbfread ebaysdk firebase_admin pyOpenSSL

Step 10: Setting Permissions On Home Folder

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

Step 11: Create Custom Module Directory

sudo su odoo -c "mkdir /opt/odoo/odoo16/odoo-custom-addons"

Step 12: Create Server Config File

Odoo will use the config file to determine the database, port number, logfile location, etc., during runtime.

sudo touch /etc/odoo16.conf
sudo nano /etc/odoo16.conf

[options]
; Database operations password:
admin_passwd = PASSWORD
db_host = localhost

db_user = odoo16
db_password = False
http_port = 8069
logfile = /var/log/odoo/odoo16-server.log
data_dir = /opt/odoo/odoo16/.local/share/Odoo
addons_path = /opt/odoo/odoo16/server-addons/addons,/opt/odoo/odoo16/odoo-custom-addons

Step 13: Set permission for config file

sudo chown odoo:odoo /etc/odoo16.conf
sudo chmod 640 /etc/odoo16.conf

Step 14: Create service file

This service file will ensure that our Odoo system is up and running after every server restart.

sudo nano /etc/systemd/system/odoo16.service

[Unit]
Description=Odoo
Requires=postgresql.service
After=network.target postgresql.service
[Service]
Type=simple
SyslogIdentifier=odoo
PermissionsStartOnly=true
User=odoo
Group=odoo
ExecStart=/opt/odoo/odoo16/odoo-venv/bin/python3 /opt/odoo/odoo16/server-addons/odoo-bin -c /etc/odoo16.conf
StandardOutput=journal+console
[Install]
WantedBy=multi-user.target

Step 15: Set permission for service file

sudo chmod 755 /etc/systemd/system/odoo16.service
sudo chown root: /etc/systemd/system/odoo16.service

 

Step 16: Service Commands

sudo systemctl start odoo16.service
sudo systemctl status odoo16.service
sudo systemctl restart odoo16.service

sudo systemctl daemon-reload

Step 17: Enable the Odoo service on system startup

sudo systemctl enable odoo16.service
