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 postgresql@14-main.service

[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
   Main PID: 32045 (python3)
      Tasks: 4 (limit: 4609)
     Memory: 90.4M (peak: 90.8M)
        CPU: 1.575s
     CGroup: /system.slice/odoo18.service
             └─32045 /opt/odoo18/odoo18-venv/bin/python3 /opt/odoo18/odoo18/odoo-bin -c /etc/odoo18.conf

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.
