Odoo is a simple and most popular open-source intuitive suite of business applications that support companies or individuals to run and manage their business. Using this platform, individuals can manage invoices, customers, inventories, products, and more. It includes a wide range of accounting and human resource components to help manage finances and employees.

You can install this platform in different ways, according to business use cases and available technologies. The most simple and easiest way to install this platform from Odoo official Apt repository. In this article, we will briefly explain how to install and configure the Odoo 14 server on Ubuntu 20.04 system.

Before starting the installation, you need to install some prerequisites on your system that are necessary to run this software. So, follow the following steps to install all prerequisites:

Step 1: Install Dependencies or Prerequisites of Odoo 14

For the custom installation of Odoo 14, you need to install required packages such as Node.js, Git, Pip, and other tools on your system. The following command is used to install the required packages:

$ sudo apt update

$ 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 2: Create Odoo user

You can’t run Odoo under the root user due to some security risk. Therefore, you will create a new user for running the Odoo services. Users will group under the home directory such as /opt/odoo14. Using the following command you can perform this task:

$ sudo useradd -m -d /opt/odoo14 -U -r -s /bin/bash odoo14

You can assign any name to the above user as per your requirements.

Step 3: Install PostgreSQL

Odoo platform stores contents using the PostgreSQL database. So, you will install it with all dependencies by using the following command:

$ sudo apt install postgresql

After completing the installation of PostgreSQL, create a user with the exact same name as you have created the above Odoo system user. In the above step, we have created an Odoo user with the name odoo14. Therefore, the name of the PostgreSQL user will remain the same.

$ sudo su - postgres -c "createuser -s odoo14"

Step 4: Install wkhtmltopdf

The wkhtmltopdf is an open-source and set of command-line tools that are used for generating PDF reports and image formats from the HTML design. So, using these tools, you can print PDF reports in Odoo platform, you will install the wkhtmltox package. The wkhtmltopdf version 0.12.5 is recommended for Odoo14, which you can easily download from Github:

$ sudo wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.bionic_amd64.deb

Once the download is completed, install this package by using the following command:

$ sudo apt install ./wkhtmltox_0.12.6-1.bionic_amd64.deb

As you have seen, all prerequisites have been installed on your system. Now, you can start the installation of Odoo14 using the following method:

Step 5: Install and Configure Odoo 14

We will install Odoo 14 inside the python virtual environment. So, switch a user as odoo14 which we have created in the above user creation step. Run the following command to change user:

$ sudo su - odoo14

Now, in the next step clone the Odoo 14 package by using the following command:

$ git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 /opt/odoo14/odoo

For Odoo installation, you need to create a new python virtual environment using the below-given commands:

$ cd /opt/odoo14

$ python3 -m venv odoo-venv

The virtual environment will be activated by using the following command:

$ source odoo-venv/bin/activate

Now, using pip3 install all the necessary packages.

$ pip3 install wheel

$ pip3 install -r odoo/requirements.txt

Once you have installed the above packages, deactivate the virtual environment using the below-given command:

$ deactivate

To keep the third party addons, create a new directory.

$ mkdir /opt/odoo14/odoo-custom-addons

Exit from this environment, type the following command:

$ exit

Create a new configuration file for Odoo 14 and paste the following content into it:

$ sudo nano /etc/odoo14.conf

[options]

; This is the password that allows database operations:

admin_passwd = my_admin_passwd

db_host = False

db_port = False

db_user = odoo14

db_password = False

addons_path = /opt/odoo14/odoo/addons,/opt/odoo14/odoo-custom-addons

Step 6: Create Systemd Unit files

Create a new service unit file named ‘odoo14.service’ by typing the following command and paste the below content in this file:

$ sudo nano /etc/systemd/system/odoo14.service

[Unit]

Description=Odoo14

Requires=postgresql.service

After=network.target postgresql.service

[Service]

Type=simple

SyslogIdentifier=odoo14

PermissionsStartOnly=true

User=odoo14

Group=odoo14

ExecStart=/opt/odoo14/odoo-venv/bin/python3 /opt/odoo14/odoo/odoo-bin -c /etc/odoo14.conf

StandardOutput=journal+console

[Install]

WantedBy=multi-user.target

Now, reload the systemd unit daemon and enable the Odoo 14 services.

$ sudo systemctl daemon-reload

$ sudo systemctl enable --now odoo14

Check the status of Odoo services that they are running or not:

$ sudo systemctl status odoo14

The following output you will retrieve on executing the above command:

To check the Odoo messages logs, use the below-given command on the terminal:

$ sudo journalctl -u odoo14

Step 7: Test the installation of Odoo14

To test the installation, type localhost: 8069 or www.example.com:8069 in your browser and you will see the following interface in your browser:
