How to Install Odoo 14 on Ubuntu 20.04 LTS

Odoo 14

Odoo has launched the latest version of Odoo 14 with so many exciting features. Let us see the steps to install Odoo 14 in the ubuntu server with the version of 20.04 LTS. 


You can watch the following video if you need an illustrative understanding of the same:

Follow the below steps to install Odoo 14 on Ubuntu 20.04 LTS


Step-1: Keep update your Server

First of all login to the server using the ssh command. Eg: ssh username@<IP address>. Then use the following command to update your system. 

sudo apt-get update
sudo apt-get upgrade

Step 2: Secure your system

After updating the server we should ensure that the server is remotely accessible. Furthermore, install Fail2ban which is used to protect from SSH attacks 

sudo apt-get install openssh-server fail2ban

Step 3: Create a system user

Now let us create a new system user for the Odoo service. Further then we will limit the permissions of all Odoo related files and directories for this specific user.

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

Step 4: Installing Packages and libraries

Next step is to install some libraries and package dependencies to run Odoo. 

Install pip3:
sudo apt-get install -y python3-pip
Install Packages and libraries:

sudo apt-get install python-dev python3-dev libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev build-essential libssl-dev libffi-dev libmysqlclient-dev libjpeg-dev libpq-dev libjpeg8-dev liblcms2-dev libblas-dev libatlas-base-dev 

Ensure that all packages are successfully installed. Moreover, there are some web dependencies that also need to be installed.

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

Step: 5: Configure Postgresql

As Odoo’s databases are handled by the Postgrsql database server. Therefore,  next we need to set-up Postgresql properly. 

Install Postgres from the Debian repository.

sudo apt-get install postgresql

Then we have to create a database user for managing Odoo databases. Therefore, initially we need to switch user to Postgres
sudo su - postgres

Now create a user odoo14 with the following command. Furthermore, at the time you must have to provide a new password for the user odoo14 and that password is needed to provide in the Odoo configuration file at the last step of the installation.

createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo14

Next we have to assign this user as a superuser for getting more privileges.

psql
ALTER USER odoo14 WITH SUPERUSER;

This will print a success message in the terminal. In addition,  exit from the psql and Postgres. With the following commands.

\q
exit

Step 6: Get Odoo community from git

Now as software is installed as the user settings are configured next, we have to place the Odoo source file into our server. Additionally, we can easily clone the community edition from Odoo’s GitHub repository. 
To clone from git we must firstly ensure that git is installed in the server.

sudo apt-get install git

Now before cloning, we have to change the system user as odoo (which is created in Step 3) to make the Odoo system more secure.

sudo su - odoo -s /bin/bash

Next step is to clone from odoo repository and the corresponding branch

git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 --single-branch .

Source files are cloned to the home directory of user odoo. Moreover, the home directory of the user is specified at the time of user creation.  Which is /opt/odoo. 
Now exit and continue with the installation.

exit

Step 7: Install required python packages

Odoo uses various python packages and libraries for different purposes. To run Odoo we need to install them using pip3. Furthermore, the required dependencies are listed in requirement.txt file which is contained in the Odoo folder. Therefore, we can specify this file to the pip install command which will automatically install packages listed in the file requirement.txt one by one

sudo pip3 install -r /opt/odoo/requirements.txt

We have to ensure that every package is installed without fail. On the contrary of a mishap, it will cause an error at the time of run odoo.

Odoo uses wkhtmltopdf for printing pdf reports. In addition, the latest edition of Odoo supports the 0.12.5 version of wkhtmltopdf to support headers and footers.
You can use following commands to download and install wkhtmltopdf


sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb
sudo dpkg -i wkhtmltox_0.12.5-1.bionic_amd64.deb
sudo apt install -f

Step 8: Configuration of Odoo

Odoo wants to know some information such as database user, password, addons locations, etc. to run the system. Moreover these will be provided in the configuration file. Therefore our net primary priority should be to create a configuration file for Odoo. Moreover, there is a sample file of configuration available within the Odoo folder which can be copied to a specific location. Usually, we place configuration files in /etc location.
To copy the configuration file to /etc :

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

Next step is we need to provide necessary details into the file. 

sudo nano /etc/odoo.conf

Update conf file same as shown in the below code:

[options]
   ; This is the password that allows database operations:
   admin_passwd = admin
   db_host = False
   db_port = False
   db_user = odoo14
   db_password = False
   addons_path = /opt/odoo/addons
   logfile = /var/log/odoo/odoo.log

Furthermore the configuration file should at least have the following parameters:

admin_passwd: Provide strong password, it will required during database create/delete/restore operations
db_host: the database host
db_port:  the database port
db_user: the database user name
db_password: provide db user password
addons_path: if you have enterprise edition or third party modules create another directory and specify the paths here separated by commas
logfile: the log file path

We need to set access rights to the system used in the conf file that can be done by using the following command:

sudo chown odoo: /etc/odoo.conf
sudo chmod 640 /etc/odoo.conf

Odoo will maintain logs in a log file that is specified in the configuration. Moreover, you can create a directory for logs. Usually, logs are contained in the location /var/log therefore, we can also create a directory inside this location named odoo.

sudo mkdir /var/log/odoo

As we did earlier, this directory has also set permission for user odoo.

sudo chown odoo:root /var/log/odoo

Step 9: Create new service for odoo

As we have  successfully configured odoo lets create create a service for Odoo.
For that create a new file in /etc/systemd/system named ‘odoo.service’.

sudo nano /etc/systemd/system/odoo.service

Further place the following into the file.

[Unit]
   Description=Odoo
   Documentation=http://www.odoo.com
   [Service]
   # Ubuntu/Debian convention:
   Type=simple
   User=odoo
   ExecStart=/opt/odoo/odoo-bin -c /etc/odoo.conf
   [Install]
   WantedBy=default.target

Now we have to set permissions for the root user to this file.

sudo chmod 755 /etc/systemd/system/odoo.service
sudo chown root: /etc/systemd/system/odoo.service

Step 10: Run Odoo 14

As the installation procedures of the platform are successfully completed. Let’s start and run certain tests. Use the following command to start odoo service.

sudo systemctl start odoo.service

Moreover, check status of odoo service using the following command:

sudo systemctl status odoo.service

If it is in the active state you can access Odoo by entering the following URL.

“http://<your_domain_or_IP_address>:8069”

If the process is operating without any errors the page will be redirected to Odoo’s database creation page.

You can check the log file specified in the configuration file.

sudo tail -f /var/log/odoo/odoo.log

If the odoo runs successfully, the installation process is completed. You can run the odoo using the previous command.

If you need Odoo service to start automatically on boot time, you can use the following command.

sudo systemctl enable odoo.service
