Step 1: Open the Terminal

To begin, you need to access the command line interface in Ubuntu. Press Ctrl + Alt + T to open the Terminal application.

Step 2: Update Your System

First, update your system packages to ensure you’re working with the latest versions. Type the following command and press Enter:

sudo apt update && sudo apt upgrade

Enter your password when prompted, and wait for the update process to complete.

Step 3: Install Dependencies

Odoo requires certain dependencies to function correctly. Run the following command to install them:

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 libldb-dev libldap2-dev libtirpc-dev

Step 4: Create an Odoo User

Create a new system user for Odoo and assign it a home directory:

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

Step 5: Install PostgreSQL

Odoo uses PostgreSQL as its database management system. Install PostgreSQL with this command:

sudo apt install postgresql

After installation, create a new PostgreSQL user for Odoo:

sudo su - postgres -c "createuser -s odoo"

Step 6: Install Wkhtmltopdf

Wkhtmltopdf is a dependency for generating PDF reports in Odoo. Download and install it using these commands:

wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb sudo apt install ./wkhtmltox_0.12.5-1.bionic_amd64.deb

Step 7: Download Odoo 16

Switch to the Odoo user and download the Odoo 16 source code:

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

Step 8: Create a Virtual Environment

Create a new virtual environment for Odoo and activate it:

python3 -m venv /opt/odoo/odoo16-venv source /opt/odoo/odoo16-venv/bin/activate

Step 9: Install Python Dependencies

Within the virtual environment, install the required Python packages:

pip install wheel pip install -r /opt/odoo/odoo16/requirements.txt

Deactivate the virtual environment when finished:

deactivate

Step 10: Configure Odoo

Create a configuration file for Odoo:

sudo mkdir /etc/odoo sudo touch /etc/odoo/odoo.conf sudo nano /etc/odoo/odoo.conf ``

Copy and paste the following configuration settings into the /etc/odoo/odoo.conf file:

[options]
; This is the password that allows database operations:
admin_passwd = your_strong_admin_password
db_host = False
db_port = False
db_user = odoo
db_password = False
addons_path = /opt/odoo/odoo16/addons

Replace your_strong_admin_password with a secure password of your choice. Save the file and exit by pressing Ctrl + X, followed by Y and Enter.

Step 11: Create a Systemd Service File

Create a systemd service file to manage the Odoo service:

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

Paste the following content into the odoo.service file:

[Unit]
Description=Odoo16
Requires=postgresql.service
After=network.target postgresql.service

[Service]
Type=simple
SyslogIdentifier=odoo16
PermissionsStartOnly=true
User=odoo
Group=odoo
ExecStart=/opt/odoo/odoo16-venv/bin/python3 /opt/odoo/odoo16/odoo-bin -c /etc/odoo/odoo.conf
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

Save and exit by pressing Ctrl + X, followed by Y and Enter.

Step 12: Enable and Start the Odoo Service

Enable the Odoo service to start automatically at boot:sudo systemctl enable odoo

Start the Odoo service:

sudo systemctl start odoo

Check the status of the Odoo service to ensure it’s running:

sudo systemctl status odoo

If the service is running, you’ll see an “active (running)” status.

Step 13: Access Odoo in Your Web Browser

Open your web browser and navigate http://your_server_ip_or_domain:8069

Replace your_server_ip_or_domain with your server’s IP address or domain name. You should see the Odoo setup page, where you can create a new database and start using Odoo 16.
