Odoo Installation

Online

Demo :
To simply get a quick idea of Odoo, demo instances are available. They have shared instances that only live for a few hours, and can be used to browse around and try things out with no commitment.

SaaS :

Odoo’s SaaS provides private instances and starts out free. It’s Fully managed and migrated by Odoo S.A.,
It can be used to discover and test Odoo and do non-code customizations (i.e. incompatible with custom modules or the Odoo Apps Store) without having to install it locally. Like demo instances, SaaS instances require no local installation, a web browser is sufficient.

Packaged installers

Odoo provides packaged installers for Windows, deb-based distributions (Debian, Ubuntu,) and RPM-based distributions (Fedora, CentOS, RHEL, ) for both the Community and Enterprise versions. These packages automatically set up all dependencies (for the Community version), but maybe difficult to keep up-to-date.

Official Community packages with all relevant dependency requirements are available on our nightly server. Both Community and Enterprise packages can be downloaded from our Download page (you must be logged in as a paying customer or partner to download the Enterprise packages).

Source Install

The source “installation” really is about not installing Odoo and running it directly from the source instead.
This can be more convenient for module developers as the Odoo source is more easily accessible than using the packaged installation.

It also makes starting and stopping Odoo more flexible and explicit than the services set up by the packaged installations, and allows overriding settings using command-line parameters without needing to edit a configuration file. Finally, it provides greater control over the system’s set up and allows more easily keeping (and running) multiple versions of Odoo side-by-side.

Docker

If you usually use docker for development or deployment, an official docker base image is available.

Below procedure to be followed to install Odoo 12.0 with Ubuntu 16.04

Step 1: Update the server

Please use these commands to make sure your system is up-to-date

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.

Get the most compatible version of wkhtmltopdf is 0.12.1 by running below command

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 a 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.
