How to install odoo19 on ubuntu 24.04

ssh username@ip_address -p portnumber

sudo apt update && sudo apt upgrade -y

lsb_release -a

You should see Ubuntu 24.04 as the release.

⚙️Step 2: Create an Odoo System User

Create a dedicated system user to run Odoo:

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

This keeps the Odoo installation separate and secure.

⚙️Step 3: Install Dependencies

Odoo runs on Python, so we need various build tools and libraries:

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

These packages support Odoo’s core features.

⚙️Step 4: Install PostgreSQL

Odoo uses PostgreSQL to store data:

sudo apt install postgresql -y

Now create a PostgreSQL role for Odoo:

sudo su - postgres -c "createuser -s odoo19"

This role will manage the Odoo database.

Alter postgres user password

sudo su - postgres
psql
alter user odoo19 with password 'password_we_need';
exit 

⚙️Step 5: Install wkhtmltopdf

Odoo uses wkhtmltopdf to generate PDFs (reports, invoices, etc.). The Ubuntu repo version isn’t fully compatible, so download the patched release:

cd /tmp
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-2/wkhtmltox_0.12.6.1-2.jammy_amd64.deb
sudo apt install ./wkhtmltox_0.12.6.1-2.jammy_amd64.deb

You can verify installation:

wkhtmltopdf --version

You should see version 0.12.6.1 confirmed.

⚙️Step 6: Install Odoo 19

Switch to the Odoo user:

sudo su - odoo19

Clone the Odoo 19 source code:

git clone https://github.com/odoo/odoo --depth 1 --branch 19.0 odoo19

Create a Python virtual environment and activate:

python3 -m venv odoo19-venv
source odoo19-venv/bin/activate

Install odoo requirements

pip install wheel

pip install -r odoo19/requirements.txt

deactivate virtual environment

deactivate

Then prepare a directory for custom modules:

mkdir /opt/odoo19/odoo19/custom-addons

Exit back to sudo user:

exit

Now create the Odoo config file:

sudo nano /etc/odoo19.conf

Paste this configuration:

[options]
admin_passwd = <YOUR_STRONG_MASTER_PASSWORD>
db_user = odoo19
db_password = password_we_need
addons_path = /opt/odoo19/odoo19/addons,/opt/odoo19/odoo19/custom-addons
http_port = 8069

⚠️ Replace <YOUR_STRONG_MASTER_PASSWORD> with a secure password.

⚙️ Step 7: Create a Systemd Service

Create a Systemd unit file so you can manage Odoo like a service:

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

Paste:

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

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

[Install]
WantedBy=multi-user.target

To exit from nano (ctrl + x, y and Enter)

Then reload and start:

sudo systemctl daemon-reload
sudo systemctl start odoo19
sudo systemctl enable odoo19

You can check status with:

sudo systemctl status odoo19

Odoo should now be running on http://<YOUR_SERVER_IP>:8069.
