install odoo 16 on Ubuntu 20.04

The much-anticipated release of Odoo version 16 has finally arrived. For the Community Edition Source Code, visit the GitHub LINK provided.

In this comprehensive guide, I will walk you through the process of installing Odoo version 16 (Community Edition) on your Ubuntu 20.04 system.

If you already have Python installed, please ensure it is at least version 3.5 or the latest.

To begin, open your terminal and carefully execute the following commands, step-by-step, to achieve optimal results:

Step 1 :

Update the apt source lists:

sudo apt-get update

Step 2 :

Create the Odoo user who will own and operate the application:

sudo adduser --system --home=/opt/odoo --group odoo

Step 3 :

Install and configure the PostgreSQL database server:

sudo apt-get install -y postgresql

After successfully installing PostgreSQL, the next step is setting up a new user dedicated to our Odoo application. This user will handle all interactions with the database on behalf of Odoo.

sudo service postgresql start

sudo su - postgres

createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo
Enter password for new role: *****
Enter it again:*****

Finally, exit from the Postgres user account.

exit

Step 4:

Installing Odoo version 16 Community Edition hosted on GitHub. Ensure that GIT is installed on your system; if not, install it using the simple command:

sudo apt-get install -y git

Switch to the Odoo user account.

sudo su - odoo -s /bin/bash

Clone the latest branch of Odoo, which, in our case, is version 16.0 from GitHub.

git clone https://www.github.com/odoo/odoo --depth 1 --branch 16.0 --single-branch .

exit

Step 5:

Install the necessary Python libraries and other dependencies required for the application. Odoo 16 will utilize Python 3.5 (which comes pre-installed on Ubuntu). To easily install all dependent libraries, we'll install pip3 on our server as follows:

sudo apt-get install -y python3-pip

Once pip3 is installed, we can proceed with installing the other necessary libraries using pip3 as well.

pip3 install -r requirements.txt

or

pip3 install Babel decorator docutils ebaysdk 
feedparser gevent greenlet html2text Jinja2 
lxml Mako MarkupSafe mock num2words ofxparse 
passlib xlwt Pillow psutil psycogreen psycopg2 
pydot pyparsing XlsxWriter PyPDF2 pyserial 
python-dateutil python-openid xlrd pytz pyusb 
PyYAML qrcode reportlab requests six suds-jurko 
vatnumber vobject Werkzeug 

Next, we'll install Odoo 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

With all the packages in place, we are now ready to proceed with the installation of the Odoo server.

Step 6:

The next task is to create a configuration file for Odoo. But before doing so, we'll create a directory to store the server logs and assign proper ownership to it:

sudo mkdir /var/log/odoo

sudo chown odoo:root /var/log/odoo

Next, create the configuration file for the Odoo server. The application will utilize these configurations to run based on your specific requirements.

sudo nano /etc/odoo-server.conf

A sample configuration file will resemble the following:

[options]
; This is the password that allows database operations:
; admin_passwd = admin
db_host = False
db_port = False
db_user = odoo
db_password = False
logfile = /var/log/odoo/odoo-server.log
addons_path = /opt/odoo/addons,/opt/odoo/odoo/addons

(Make sure to use the same password you used back in Step 3.)

Once the configuration file is created, we will set the ownership rights accordingly.

sudo chown odoo: /etc/odoo-server.conf

sudo chmod 640 /etc/odoo-server.conf

Step 7:

Create a service using the commands mentioned above:

sudo cp odoo-service new_file_name

or

sudo nano new_file_name

Make the init.d file executable and ensure it is owned by the root:

sudo chmod 755 /etc/init.d/new_file_name

sudo chmod root /etc/init.d/new_file_name

now execute this command:

sudo systemctl daemon-reload

sudo service new_file_name restart

if you don't want to create a new service file then use this command:

sudo chmod 755 /etc/init.d/odoo-server

sudo chown root: /etc/init.d/odoo-server

Step 8:

Testing the server:

To start the Odoo server, type:

sudo /etc/init.d/odoo-server start

You should now be able to view the log-file as follows:

sudo nano /var/log/odoo/odoo-server.log

If you encounter any issues during this step, feel free to comment on this blog, and I'll do my utmost to assist you.

[OPTIONAL] Additionally, for debugging purposes, you can start the server manually to check if it runs smoothly, using the following commands:

sudo su - odoo

[sudo] password for user_name:

cd odoo-server

./odoo-bin

If the log file appears satisfactory, you can access the Odoo server in your browser using the URL:

http://0.0.0.0:8069/

or

http://localhost:8069/

How to run the server:

For starting the server:

sudo service odoo-server start

For stopping the server:

sudo service odoo-server stop

For restarting the server:

sudo service odoo-server restart

That's a wrap!
