    liblcms2-dev libwebp-dev libharfbuzz-dev libfribidi-dev \
    libxcb1-dev libpq5 wkhtmltopdf

Step 3: Install PostgreSQL and Create User


sudo apt install -y postgresql
sudo -u postgres createuser -s odoo19

Step 4: Get Odoo Source Code


#Switch to odoo19 user:

sudo -i -u odoo19

#Clone Odoo 19 source code:

cd /opt/odoo19
wget https://github.com/odoo/odoo/archive/refs/heads/19.0.zip -O odoo19.zip

#Unzip & remove extra content:

unzip odoo19.zip
mv odoo-19.0/* odoo-19.0/.[!.]* .
rm -rf odoo-19.0 odoo19.zip

Step 5: Create Python Virtual Environment


#Inside /opt/odoo19:
cd /opt/odoo19
python3 -m venv venv
source venv/bin/activate

#Upgrade pip:
pip install --upgrade pip wheel setuptools

#Install Python dependencies:
pip install -r requirements.txt

#Deactivate venv & exit from odoo19 user:
deactivate
exit

Step 6: Create Odoo Configuration File

Create & edit a file witn name 'odoo19.conf' inside etc:


sudo nano /etc/odoo19.conf

Add the following content in 'odoo19.conf':


[options]
; Database
admin_passwd = 12345
db_host = False
db_port = False
db_user = odoo19
db_password = False
http_port = 8069

addons_path = /opt/odoo19/addons

Grant access to user odoo19 to the file:


sudo chown odoo19:odoo19 /etc/odoo19.conf
sudo chmod 640 /etc/odoo19.conf

Step 7: Verify Installation

Run the odoo server by command:


sudo -i -u odoo19
cd /opt/odoo19
source venv/bin/activate 
python3 odoo-bin -c /etc/odoo19.conf

Odoo should be running at:


http://localhost:8069

If you face an error:


- Try to read the error text
- If it is some dependancey issue than install it by using "pip install dependancy_name
- If it is port related issue, than try to kill the servic which is using the same port
- If it is permission like issue than try to grant access to 'odoo19' user
- If it is database related issue than fix it by edit postgres config file

Step 8: Access Odoo 19

Open your browser and navigate to http://localhost:8069.
If you are using a remote server, replace localhost with your server's IP address.

Optional: Nginx as a Reverse Proxy

If you want to serve Odoo behind a domain name, you can install and configure Nginx as a reverse proxy.
