How to Install Odoo 15 on Ubuntu 20.04 VPS


This article shows how to install Odoo 15 on Ubuntu 20.04. Odoo is a popular open-source suite of business apps that help companies to manage and run their business. It includes a wide range of applications such as CRM, e-Commerce, website builder, billing, accounting, manufacturing, warehouse, project management, inventory, and much more, all seamlessly integrated.

Installing Odoo in a virtual environment, or deploying as a Docker container, gives you more control over the application and allows you to run multiple Odoo instances on the same system.


OS: Ubuntu 20.04

Resources: 2-core CPU & 2GB of RAM

Access: SSH connection to the server

Permissions: a user with ‘sudo’ privileges

Step 1. Log in to the Ubuntu VPS via SSH

The first step in the installation is to connect to your server via ssh. You can log in to the server using ssh:

$ ssh username@IP_Address -p Port_number

Step 2. Update Packages

Then let’s update existing Ubuntu packages and upgrade them into newer versions.

$ sudo apt-get update
$ sudo apt-get upgrade -y

Step 3. Install Dependencies

The first step is to install Git , Pip , Node.js , and development [tools required to build]

$ sudo apt install git python3-pip build-essential wget python3-dev python3-venv \ 
    python3-wheel libfreetype6-dev libxml2-dev libzip-dev libldap2-dev libsasl2-dev \ 
    python3-setuptools node-less libjpeg-dev zlib1g-dev libpq-dev \ 
    libxslt1-dev libldap2-dev libtiff5-dev libjpeg8-dev libopenjp2-7-dev \ 
    liblcms2-dev libwebp-dev libharfbuzz-dev libfribidi-dev libxcb1-dev

Step 4. Create an Odoo user

Create a new user called odoo15 with home directory /opt/odoo15. This prevents the security risks posed by running odoo under the root user. You can do it with this command. You can give any name to the user. However, be careful to create a PostgreSQL user with the same name.

$ sudo useradd -m -d /opt/odoo15 -U -r -s /bin/bash odoo15

Step 5. Install and configure PostgreSQL

In this step, you need to set up the database server. Odoo uses PostgreSQL as the database back-end. Install the database server for Odoo By using the following command.

$ sudo apt install postgresql -y

Now you need to create a PostgreSQL user for the handling of the database server i.e. PostgreSQL. In our case, we will create a PostgreSQL user with the same name as the previously created system user i.e odoo15

$ sudo su - postgres -c "createuser -s odoo15"

Step 6. Installing wkhtmltopdf

Wkhtmltopdf is the package that allows Odoo 15 to print PDF reports. It converts HTML (web page markup) to PDF, but it’s not present in the official package list nor the EPEL repository. We’ll download and install the package from Github.

$ sudo wget

After it has downloaded, we’ll use this command to install it.

$ sudo apt install ./wkhtmltox_0.12.5-1.bionic_amd64.deb

Step 7. Install Odoo 15 on Ubuntu and Configure Odoo 15

First, we’ll change the user to the one we created i.e odoo15.

$ sudo su - odoo15

Next, we’ll clone the Odoo 15 source code from github.

odoo15$ git clone --depth 1 --branch 15.0 /opt/odoo15/odoo

To separate Odoo’s Python modules from the system’s Python modules, we’ll need to set up a Python Virtual Environment inside which we’ll install Odoo. Use these commands to achieve this.

odoo15$ cd /opt/odoo15
odoo15$ python3 -m venv odoo-venv

Then we activate the virtual environment.

$ source odoo-venv/bin/activate

Step 8. Install Odoo Dependencies

All dependencies for Odoo are specified in the requirements.txt file. We’ll use pip to install all required Python modules.

(odoo-venv) odoo15$ pip3 install wheel
(odoo-venv) odoo15$ pip3 install -r odoo/requirements.txt

When we’re finished, we deactivate the virtual environment

(odoo-venv)$ deactivate

Step 9. Create directory for the 3rd party addons

We’ll create a new directory a separate directory for the 3rd party addons.

odoo15$ mkdir /opt/odoo15/odoo-custom-addons

This directory should later be added to the addons_path parameter which defines a list of directories where Odoo searches for modules. After this step we will switch back to the sudo user using this command.

odoo15$ exit

Step 10. Create a configuration file for the Odoo Installation

The command below allow you to create and edit a *.conf file.

$ sudo nano /etc/odoo15.conf

Add the following configuration information to the file. Note: Remember to change the admin_passwd to something more secure.

; This is the password that allows database operations:
admin_passwd = my_admin_passwd
db_host = False
db_port = False
db_user = odoo15
db_password = False
xmlrpc_port = 8060
logfile = /var/log/odoo15/odoo.log
logrotate = True
addons_path = /opt/odoo15/odoo/addons,/opt/odoo15/odoo-custom-addons

Step 11. Creating Systemd Unit File

This is a configuration ini-style file that holds configuration information about a service. We’ll be creating a file named “odoo15.service”.

$ sudo nano /etc/systemd/system/odoo15.service

Add the following configuration information to the file.

Requires=postgresql.service postgresql.service

ExecStart=/opt/odoo15/odoo-venv/bin/python3 /opt/odoo15/odoo/odoo-bin -c /etc/odoo15.conf


With the next command we are notifying systemd that the new file exists and reloading the daemon.

$ sudo systemctl daemon-reload

Next, we start the Odoo service and enable it to run on system boot.

$ sudo systemctl enable --now odoo15

Now we check if the service is running.

$ sudo systemctl status odoo15

You should get the following output.

sudo systemctl status odoo15 output

This next command will allow you to check on the messages logged by the odoo15 service.

$ sudo journalctl -u odoo15

Step 12. Testing the Odoo Installation

sudo systemctl status odoo15 output


Congratulations! You have successfully installed Odoo 15 on Ubuntu 20.04. The tutorial is tested on VPS Mart, so it works fine on Our Ubuntu VPS Hosting.
