Odoo is a suite of open-source business applications covering various needs such as CRM (Customer Relationship Management), e-commerce, accounting, inventory management, and project management. It is designed to be customizable and modular, allowing businesses to tailor it to their specific requirements.
Odoo is built on a modular architecture, meaning users can start with the basic modules and add more functionalities as needed. It offers both an open-source and free-to-use community edition and an enterprise edition with additional features and support, which requires a subscription fee.
In this tutorial, we will show you how to install Odoo 18 on Ubuntu 24.04.
Step 1 – Install Required Dependencies
Odoo is a Python-based software. Therefore, you will need to install Python and some additional dependencies on your server. You can install all of them using the following command:
apt-get install -y python3-pip python3-dev python3-venv libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev build-essential libssl-dev libffi-dev libmysqlclient-dev libjpeg-dev libpq-dev libjpeg8-dev liblcms2-dev libblas-dev libatlas-base-dev -y
Next, install the NPM package manager.
apt-get install -y npm
Then, install other dependencies using NPM.
npm install -g less less-plugin-clean-css
Next, install the node-less package.
apt-get install -y node-less
Next, download wkhtmltopdf package and install it using the following command:
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.bionic_amd64.deb
dpkg -i wkhtmltox_0.12.6-1.bionic_amd64.deb
apt install -f
Step 2 – Install PostgreSQL
Odoo uses PostgreSQL as a database backend. You can install it using the following command:
apt-get install postgresql -y
After the successful installation, verify the PostgreSQL status using the following command:
systemctl status postgresql
Output:
● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)
Active: active (exited) since Sat 2025-05-12 04:13:39 UTC; 9s ago
Process: 16418 ExecStart=/bin/true (code=exited, status=0/SUCCESS)
Main PID: 16418 (code=exited, status=0/SUCCESS)
CPU: 1ms
May 12 04:13:39 ubuntu24 systemd[1]: Starting PostgreSQL RDBMS...
May 12 04:13:39 ubuntu24 systemd[1]: Finished PostgreSQL RDBMS.
Next, create a user for Odoo using the following command:
useradd -m -U -r -d /opt/odoo18 -s /bin/bash odoo18
Also, create the same user for PostgreSQL.
su - postgres -c "createuser -s odoo18"
Step 3 – Install and Configure Odoo
First, log in as an Odoo user and download the Odoo 18 using the following command:
su - odoo18 git clone https://www.github.com/odoo/odoo --depth 1 --branch 18.0 /opt/odoo18/odoo18
Next, create a Python virtual environment for Odoo.
cd /opt/odoo18 python3 -m venv odoo18-venv
Next, activate the virtual environment.
source odoo18-venv/bin/activate
Next, update the pip to the latest version.
pip install --upgrade pip
Next, install the Weel package.
pip3 install wheel
Next, install additional Python dependencies.
pip3 install -r odoo18/requirements.txt
Finally, deactivate from the Python virtual environment.
deactivate
Also, log out of the Odoo user.
exit
Next, create a directory to store Odoo addons and give it proper ownership.
mkdir /opt/odoo18/odoo18-custom-addons chown -R odoo18:odoo18 /opt/odoo18/odoo18-custom-addons
Next, create a log directory and file for Odoo and set proper permissions.
mkdir -p /var/log/odoo18 touch /var/log/odoo18/odoo18.log chown -R odoo18:odoo18 /var/log/odoo18
Next, create an Odoo configuration file.
nano /etc/odoo18.conf
Add the following lines:
[options] admin_passwd = master-password db_host = False db_port = False db_user = odoo18 db_password = False xmlrpc_port = 8069 logfile = /var/log/odoo18/odoo18.log addons_path = /opt/odoo18/odoo18/addons,/opt/odoo18/odoo18-custom-addons
Step 4 – Create a Systemd File for Odoo
You will also need to create a system file to manage the Odoo service.
nano /etc/systemd/system/odoo18.service
Add the following lines:
[Unit] Description=odoo18 After=network.target [email protected] [Service] Type=simple SyslogIdentifier=odoo18 PermissionsStartOnly=true User=odoo18 Group=odoo18 ExecStart=/opt/odoo18/odoo18-venv/bin/python3 /opt/odoo18/odoo18/odoo-bin -c /etc/odoo18.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target
Save the file, then reload the systemd daemon.
systemctl daemon-reload
Now, start and enable the Odoo service.
systemctl start odoo18 systemctl enable odoo18
You can now check the Odoo status using the following command:
systemctl status odoo18
Output:
● odoo18.service - odoo18
Loaded: loaded (/etc/systemd/system/odoo18.service; disabled; preset: enabled)
Active: active (running) since Mon 2025-05-12 05:32:01 UTC; 3s ago

May 12 05:32:01 ubuntu systemd[1]: Started odoo18.service - odoo18.
Step 5 – Access Odoo Web Interface
At this point, Odoo has started listening on port 8069. You can now access it using the URL http://your-server-ip:8069. You will see the following screen.
Provide your master password and Odoo database and click on Create Database. You will see the Odoo 18 login page.
