Posted on by
NOTE: These instructions apply to Odoo 12 and Ubuntu 18.04, for Ubuntu 19.04 use this link.

Prep for Odoo:

This tutorial assumes you have a working install of Ubuntu 18.04 and root access.
  • Update Ubuntu:
sudo apt update && sudo apt-get dist-upgrade -y
  • Install Git, Wget, Unzip, Pip, Python3 and dependancies:
sudo apt-get install wget git unzip python3-pip build-essential python3-dev python3-venv python3-wheel libxslt-dev libzip-dev libldap2-dev libsasl2-dev python3-setuptools
  • Install Odoo Web Dependencies:
sudo apt-get install -y npm
sudo npm install -g less less-plugin-clean-css
sudo apt-get install node-less

Install Wkhtmltox

In order to print PDF reports, you will need the wkhtmltopdf tool. The recommended version for Odoo is 0.12.1 which is not available in the official Ubuntu 18.04 repositories.
  • Download package using wget and install:
wget https://builds.wkhtmltopdf.org/0.12.1.3/wkhtmltox_0.12.1.3-1~bionic_amd64.deb
sudo dpkg -i wkhtmltox_0.12.1.3-1~bionic_amd64.deb
If you get a dependency error: 
sudo apt-get install -f
sudo apt --fix-broken install
sudo dpkg -i wkhtmltox_0.12.1.3-1~bionic_amd64.deb
Proceed to complete install: 
sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin
sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin

Create user “odoo12”

We will create a user with a Home Directory where we will later place the Odoo12 installation from GitHub: 
sudo useradd -m -d /opt/odoo12 -U -r -s /bin/bash odoo12

Install and Setup Odoo PostgreSQL Database

  • Install PostgreSQL 10.5:
sudo apt-get install postgresql
  • Set PostgreSQL master password:
sudo passwd postgres

Create user odoo12 for PostgreSQL

We are going to create a user similar to the one we previously created to run Odoo: 
sudo su - postgres -c "createuser -s odoo12"

Install and Configure Odoo 12

Now let’s switch to odoo12 user: 
sudo su - odoo12
Clone the GitHub Repository: 
git clone https://www.github.com/odoo/odoo --depth 1 --branch 12.0 /opt/odoo12/odoo

Install Python requirements for Odoo 12

We should be in the following directory: (/opt/odoo12/)
  • Issue the command cd /opt/odoo, and then create a new virtual environment with the command:
cd /opt/odoo12
python3 -m venv odoo12-venv
Active the environment with the command: 
source odoo12-venv/bin/activate
pip3 install wheel
pip3 install -r odoo/requirements.txt
Optional: Here are additional requirements that may have been missed. 
pip3 install Babel decorator docutils ebaysdk feedparser gevent greenlet html2text Jinja2 lxml Mako MarkupSafe mock num2words ofxparse passlib Pillow psutil psycopg2 pydot pyparsing PyPDF2 pyserial python-dateutil python-openid pytz pyusb PyYAML qrcode reportlab requests six suds-jurko vatnumber vobject Werkzeug XlsxWriter xlwt xlrd gdata

Deactivate the environment, and exit back to the standard user with the commands:

deactivate
exit

Setup Odoo Config

Create custom addons Directory: 
su odoo12
mkdir /opt/odoo12/odoo-custom-addons
exit
Create the config file from sample included in GitHub: 
sudo cp /opt/odoo12/odoo/debian/odoo.conf /etc/odoo12.conf
Edit the file: 
sudo nano /etc/odoo12.conf
; Password that allows database operations:
; admin_passwd = my_admin_passwd
db_host = False
db_port = False
db_user = odoo12
db_password = False
addons_path = /opt/odoo12/odoo/addons,/opt/odoo12/odoo-custom-addons

Create Odoo12 Service

To run Odoo as a service we need to create a service unit file in the /etc/systemd/system/ directory. 
sudo nano /etc/systemd/system/odoo12.service

[Unit]
Description=Odoo12
Requires=postgresql.service
After=network.target postgresql.service

[Service]
Type=simple
SyslogIdentifier=odoo12
PermissionsStartOnly=true
User=odoo12
Group=odoo12
ExecStart=/opt/odoo12/odoo12-venv/bin/python3 /opt/odoo12/odoo/odoo-bin -c /etc/odoo12.conf StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

Load the Odoo12 service

sudo systemctl daemon-reload
sudo systemctl enable odoo12
sudo systemctl start odoo12
Check status of Odoo 12 Service 
sudo systemctl status odoo12
Should look something like this:
Goto the website and fill out the new database creation form: Use the IP of your server on port 8069:
