How to Install Odoo 12 on Ubuntu 16.04

The much-awaited Odoo 12 got released in the onset of October without disappointing any of its end users. The new version is not only embedded with new usability features but also with brand new modules. One of the significant features of Odoo 12 is the revamped accounting module which is facilitated with new components like the use of OCR and importation of vendor bills, making the accounts management more easy to use and configure. 

Odoo 12 comes with brand new Document Management module that facilitates with seamless document sharing among the team and also brand new feature of multi-website management benefiting E-commerce business in large. The functionalities of Odoo 12 are large as you explore deep.

This blog discusses the procedure to be followed while installing Odoo 12 in Ubuntu 16.04

Step 1: Update the server
Make your system updated using these two commands
sudo apt-get update
sudo apt-get upgrade

Step 2: Secure Server
It is common for all versions and many of you may be aware of this, but I'm still including this.
Run this command to make your server/system remotely accessible
sudo apt-get install openssh-server fail2ban

Step 3: Create a System User
Create a system user to run Odoo service. The source code of Odoo will reside in the home directory of the user,  if you follow these steps
sudo adduser --system --home=/opt/odoo --group odoo

Step 4: Install  and Configure PostgreSQL database server
Install PostgreSQL:
sudo apt-get install postgresql
sudo su - postgres

Create a PostgreSQL user for managing Odoo databases:
createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo12

Exit from Postgres user to continue the installation:
exit

Step 5: Install  dependencies for Odoo
Install pip 3:
sudo apt-get install -y python3-pip

After the successful installation of pip3, install dependencies using pip3:
sudo pip3 install Babel chardet decorator docutils ebaysdk feedparser gevent greenlet html2text Jinja2 libsass lxml Mako MarkupSafe mock num2words ofxparse passlib Pillow psutil psycopg2 pydot pyldap pyparsing PyPDF2 pyserial python-dateutil pytz pyusb PyYAML qrcode reportlab requests suds-jurko vatnumber vobject Werkzeug XlsxWriter xlwt xlrd

There are some web dependencies for Odoo like Node.js and less

Install these web dependencies:
sudo apt-get install -y npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
sudo npm install -g less less-plugin-clean-css
sudo apt-get install -y node-less

wkhtmltopdf is required to generate PDF reports from Odoo. Install on your server.

The most compatible version of wkhtmltopdf is 0.12.1

Get it from here,
sudo wget http://download.gna.org/wkhtmltopdf/0.12/0.12.1/wkhtmltox-0.12.1_linux-trusty-amd64.deb

Or from here,

sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.1/wkhtmltox-0.12.1_linux-trusty-amd64.deb

These two commands will trigger the downloading of the package

If these both ains websites or Clone from Github repo

Here we are cloning from Git.

So, first, we have to install Git
sudo apt-get install git

Now, we should change our user as the system user we created for Odoo. Otherwise, we will end up with access right related hurdles.
sudo su - odoo -s /bin/bash

Now we are ready to clone Odoo 12 (this is community only)
git clone https://www.github.com/odoo/odoo --depth 1 --branch 12.0 --single-branch

Exit from Odoo user to continue the installation:
exit

Step 7: Configure Odoo
At first, we are creating a log file location for Odoo. Odoo will create and maintain its log files there.
sudo mkdir /var/log/odoo

Give the full access to this directory to the Odoo user
sudo chown odoo:root /var/log/odoo

After creating a log directory, we are going to create a configuration file for Odoo.

There is a configuration file that comes with the Odoo we just downloaded.

We are copying that file to a more appropriate location
sudo cp /opt/odoo/debian/odoo.conf /etc/odoo.conf

We have to make some changes in the configuration file, to edit the file, we are using a text editor called nano
sudo nano /etc/odoo.conf

Here is the example of the configuration file:
   [options]
   ; This is the password that allows database operations:
   ; admin_passwd = admin
   db_host = False
   db_port = False
   db_user = odoo
   db_password = False
   addons_path = /opt/odoo/addons
   logfile = /var/log/odoo/odoo.log

After the configuration file is ready, we have to give the ownership of the file to the Odoo user
sudo chown odoo: /etc/odoo.conf
sudo chmod 640 /etc/odoo.conf

Step 8: Create a service to run Odoo

We have to create a system unit for Odoo so that it can start behaving like a service.

Create a new file odoo.service at /etc/systemd/system/ just like we created the file
sudo nano /etc/systemd/system/odoo.service

You can use this content for your file
   [Unit]
   Description=Odoo
   Documentation=http://www.odoo.com
   [Service]
   # Ubuntu/Debian convention:
   Type=simple
   User=odoo12
   ExecStart=/opt/odoo/odoo-bin -c /etc/odoo.conf
   [Install]
   WantedBy=default.target

Since this is a service, we are giving full rights to this file to the root user.
sudo chmod 755 /etc/systemd/system/odoo.service
sudo chown root: /etc/systemd/system/odoo.service

Step 9: Test Odoo
sudo systemctl start odoo.service
You can check the log file of Odoo
sudo tail -f /var/log/odoo/odoo.log

Step 10: Automating Starting of Odoo
This will enable the Odoo service to start automatically at boot time
sudo systemctl enable odoo.service

Step 11: Access Odoo

Open a new browser window and enter HTTP://<your_domain_or_IP_address>:8069 in the address bar

If everything is working properly, you will redirect to Odoo's database creation page.
