How to Install Odoo 19 on Ubuntu 24.04

Odoo is a powerful open-source suite of business applications including CRM, e-commerce, accounting, inventory, project management, and more. This guide will walk you through installing Odoo 19 on Ubuntu 24.04 using a Python virtual environment with PostgreSQL as the database backend and Nginx as a reverse proxy.

📋 Prerequisites:

Ubuntu 24.04 server with at least 2GB RAM
Python 3.10 or later
PostgreSQL 13 or later
User with sudo privileges
Domain name pointing to your server (for SSL)

1. Installing System Dependencies

First, update your system and install the required packages:

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

2. Installing Node.js

Ubuntu 24.04 ships with an older Node.js version. Install Node.js 22.x LTS from NodeSource:

curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt install -y nodejs
sudo npm install -g rtlcss

Verify installations:

python3 --version
node --version
npm --version

3. Creating Odoo System User

For security, create a dedicated system user to run Odoo:

sudo useradd -m -d /opt/odoo19 -U -r -s /bin/bash odoo19

4. Installing and Configuring PostgreSQL

Install PostgreSQL and create a database user:

sudo apt install -y postgresql
sudo su - postgres -c "createuser -R -S -D odoo19"

ℹ️ Note: Odoo will automatically create the database when you access it for the first time.

5. Installing wkhtmltopdf for PDF Reports

Download the official 0.12.6 build for proper PDF header/footer support:

sudo wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-3/wkhtmltox_0.12.6.1-3.jammy_amd64.deb
sudo apt install -y ./wkhtmltox_0.12.6.1-3.jammy_amd64.deb

⚠️ Warning: If you encounter dependency issues, run sudo apt --fix-broken install.

6. Installing Odoo 19 Source

Switch to the odoo19 user and clone the repository:

sudo su - odoo19
git clone https://www.github.com/odoo/odoo --depth 1 --branch 19.0 /opt/odoo19/odoo

7. Creating Python Virtual Environment

cd /opt/odoo19
python3 -m venv odoo-venv
source odoo-venv/bin/activate
pip3 install wheel
pip3 install -r odoo/requirements.txt
deactivate
exit

ℹ️ Note: If you encounter compilation errors, ensure all dependencies from Step 1 are installed.

8. Creating Odoo Configuration File

sudo nano /etc/odoo19.conf

Add the following content (change the admin_passwd to a strong password!):

[options]
admin_passwd = ChangeThisStrongPassword!
db_host = False
db_port = False
db_user = odoo19
db_password = False
addons_path = /opt/odoo19/odoo/addons,/opt/odoo19/odoo-custom-addons

9. Creating Systemd Service

sudo nano /etc/systemd/system/odoo19.service

Add the following content:

[Unit]
Description=Odoo 19
Requires=postgresql.service
After=network.target postgresql.service

[Service]
Type=simple
SyslogIdentifier=odoo19
PermissionsStartOnly=true
User=odoo19
Group=odoo19
ExecStart=/opt/odoo19/odoo-venv/bin/python3 /opt/odoo19/odoo/odoo-bin -c /etc/odoo19.conf
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

10. Starting Odoo Service

sudo systemctl daemon-reload
sudo systemctl enable --now odoo19
sudo systemctl status odoo19

11. Configuring Nginx as Reverse Proxy

Install Nginx and create the configuration file:

sudo apt install -y nginx
sudo nano /etc/nginx/sites-available/odoo.conf

Add this configuration (replace example.com with your domain):

upstream odoo {
    server 127.0.0.1:8069;
}

upstream odoochat {
    server 127.0.0.1:8072;
}

server {
    listen 80;
    listen [::]:80;
    server_name example.com www.example.com;
    return 301 https://example.com$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    http2 on;
    server_name example.com;

    proxy_read_timeout 720s;
    proxy_connect_timeout 720s;
    proxy_send_timeout 720s;

    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;

    location / {
        proxy_redirect off;
        proxy_pass http://odoo;
    }

    location /websocket {
        proxy_pass http://odoochat;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

    location ~* /web/static/ {
        proxy_cache_valid 200 90m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odoo;
    }

    gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
    gzip on;
}

12. Installing SSL Certificate with Let's Encrypt

sudo apt install -y certbot python3-certbot-nginx
sudo certbot --nginx -d example.com -d www.example.com

13. Enabling Proxy Mode in Odoo

sudo nano /etc/odoo19.conf

Add this line:

proxy_mode = True

Then restart services:

sudo systemctl restart odoo19
sudo systemctl restart nginx

14. Configuring Firewall (Optional but Recommended)

sudo ufw allow OpenSSH
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw deny 8069/tcp
sudo ufw enable

15. Enabling Multiprocessing for Production

For a system with 4 CPU cores and 8GB RAM, add these settings:

limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_request = 8192
limit_time_cpu = 600
limit_time_real = 1200
max_cron_threads = 1
workers = 5

Testing Your Installation

Open your browser and navigate to:

https://yourdomain.com

You should see the Odoo database creation screen!

🎉 Success! Odoo 19 is now installed on your Ubuntu 24.04 server.
