Login as root user and update the system to the latest packages

# apt update && sudo apt upgrade

Install Git, Pip, Node.js and the packages required for odoo

# apt install git python3-pip build-essential wget python3-dev python3-venv python3-wheel libxslt-dev libzip-dev libldap2-dev libsasl2-dev python3-setuptools node-less

Create a new user for odoo12, name it odoo12 with the home directory as /opt/odoo12 :

# useradd -m -d /opt/odoo12 -U -r -s /bin/bash odoo12

Install and Configure PostgreSQL

# apt install postgresql

Now create a PostgreSQL user with the same name as odoo user

# sudo su - postgres -c "createuser -s odoo12"

Install Wkhtmltopdf which can render HTML into PDF and various image formats. In order to print PDF reports, you will need the wkhtmltopdf tool

# wget https://builds.wkhtmltopdf.org/
# apt install ./wkhtmltox_0.12.1.3-1~bionic_amd64.deb

Once these steps are over, lets configure Odoo

Change the user into Odoo user, odoo12

# sudo su - odoo12

Git clone the odoo12 source code :

# git clone https://www.github.com/odoo/odoo --depth 1 --branch 12.0 /opt/odoo12/odoo

Once the source code is downloaded, create a new Python virtual environment for the Odoo 12 installation:

# cd /opt/odoo12
# python3 -m venv odoo-venv

Next, activate the environment with the following command:

# source odoo-venv/bin/activate

Install all required Python modules with pip3:

$ pip3 install wheel
$ pip3 install -r odoo/requirements.txt

Deactivate the environment using the following command:

$ deactivate

Create a new directory for the custom addons:

$ mkdir /opt/odoo12/odoo-custom-addons

Exit to the root user

$ exit

Copy the odoo12 sample config file :

# sudo cp /opt/odoo12/odoo/debian/odoo.conf /etc/odoo12.conf

Edit the file :

# vim /etc/odoo12.conf

^ Make sure to change the Admin password to something stronger.

To run Odoo as a service we need to create a service unit file in the /etc/systemd/system/ directory.

# vim /etc/systemd/system/odoo12.service

After=network.target postgresql.service

ExecStart=/opt/odoo12/odoo-venv/bin/python3 /opt/odoo12/odoo/odoo-bin -c /etc/odoo12.conf


# sudo systemctl daemon-reload
# sudo systemctl start odoo12

Enable the Odoo service to be automatically started at boot time:

# sudo systemctl enable odoo12

Now the odoo12 instalaltion would be accessible at yourdomain.com:8069

( Make sure to open the port 8069, both at server level and at public firewall level ( in case you case AWS, Alibaba etc ) )

Now to map the installation to the domain and not use port along with it, we need to have Nginx web-server configured.

Install Nginx :

# sudo apt install nginx
# sudo systemctl status nginx

Allow the firewall rules to enable Nginx :

sudo ufw allow 'Nginx Full'

Now secure the domain with SSL – you can use the free letsencrpyt SSL

# sudo add-apt-repository ppa:certbot/certbot

Install Certbot’s Nginx package with apt:

# sudo apt install python-certbot-nginx

Now obtain the SSL cert for the domain :

# certbot --nginx -d example.com -d www.example.com

Once this is done, the keys would be avaiable at :



Now create a config file for your domain

# vim /etc/nginx/sites-enabled/example.com

Paste the following contents ( dont forget to replace domain name and the path to SSL file )

upstream odoo {

server {
listen 80;
server_name www.example.com example.com;

include snippets/letsencrypt.conf;
return 301 https://example.com$request_uri;


server {
listen 443 ssl http2;
server_name www.example.com;

ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
return 301 https://example.com$request_uri;


server {
listen 443 ssl http2;
server_name example.com;

# Gzip

# sudo systemctl restart nginx
# vim /etc/odoo12.conf

Change proxy_mode to True

# sudo systemctl restart odoo12

At this point, your server is configured and you can access your Odoo instance at: https://example.com
