How to Install Odoo 13 on Ubuntu 20.04 – Knowledgebase – SolaDrive

Prerequisites

OS: Ubuntu 20.x (e.g. 20.04)

Resources: 2-core CPU & 2GB of RAM

Access: SSH connection to the server

Permissions: a user with ‘sudo’ privileges

Note: you can execute all of the commands below from the root user, but for security purposes, it is recommended that you use a separate user with sudo privileges.

Step 1: Connect to the Server.

In order to perform any commands on your remote server, you will need to connect to it using the SSH protocol.

Step 2: Set-up Additional Repositories

Odoo 13 depends on a lot of packages. Some are not available in the official Ubuntu repository, which is why we need to add other repositories to the package manager:

sudo add-apt-repository universe

sudo add-apt-repository ppa:deadsnakes/ppa

Note: you will have to press Enter again to confirm the action.

Step 3: Update the System

Update the list of available Ubuntu packages:

sudo apt-get update

Download and install the new version of existing packages:

sudo apt-get upgrade -y

Step 4: Create a Separate User for Odoo 13

To limit the things Odoo 13 can do within your system, let’s create a separate user:

sudo useradd -m -d /opt/odoo -U -r -s /bin/bash odoo

The user does not have administrative privileges, and it will only be able to operate within one specific directory: /opt/odoo

Step 5: Set-up PostgreSQL

PostgreSQL is used by Odoo 13 to store all of the user and application data. It’s an essential part of the application.

Install PostgreSQL:

sudo apt-get install postgresql -y

Create a dedicated odoo user in the database:

sudo su - postgres -c "createuser -s odoo"

Step 6 : Install Wkhtmltopdf and Its Dependencies

Among the extra packages that Odoo 13 requires to properly function is Wkhtmltopdf, which makes it possible for the system to print PDF reports.

You won’t find it in the official repository, however, so let’s download it manually:

sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb

Additional packages are required for Wkhtmltopdf to run. Install them with the following commands:

sudo apt-get install libjpeg-turbo8 libjpeg-turbo8 libxrender1 xfonts-75dpi xfonts-base -y

sudo apt-get install fontconfig

Note: there may be an error during this step. It’s normal. The next command will fix it.

sudo apt-get install -f

Install Wkhtmltopdf:

sudo dpkg -i wkhtmltox_0.12.5-1.bionic_amd64.deb

Point Ubuntu to the location of the installed package:

sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin

sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin

Step 7: Install the Odoo 13 Dependencies

Odoo 13 doesn’t work in a vacuum – it needs other tools, too.

Install the necessary packages with this command:

sudo apt-get install python3 python3-pip python3-suds wget git bzr gdebi-core libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev libssl-dev -y

Install additional node packages:

sudo apt-get install node-clean-css node-less git -y

Step 8. Install Python 3.6

The default Python version will not work with Odoo 13. We need to install the 3.6 version, along with all the needed tools:

sudo apt install python3.6 python3.6-dev python3.6-venv

Step 9: Download Odoo 13

To make things simpler, let’s switch to the odoo user that we created earlier:

sudo su - odoo

Let’s download the source code from the official GitHub repository (/opt/odoo/odoo13 will be our main Odoo 13 directory):

git clone https://www.github.com/odoo/odoo --depth 1 --branch 13.0 /opt/odoo/odoo13

Step 10: Set-up the Python Environment

Odoo 13 runs on the Python programming language. But it needs additional modules in order to work correctly. Let’s install them.

First of all, create a virtual Python environment for the Odoo instance (so that the modules don’t affect the system’s Python modules, and vice-versa).

cd /opt/odoo && python3 -m venv odoo13-venv

Activate the virtual environment:

source odoo13-venv/bin/activate

The library and module details are stored in the official requirements.txt file. Let’s use it to install all of the correct modules at once:

pip3 install -r odoo13/requirements.txt

Note: ignore the orange warnings if they appear.

Deactivate the virtual environment and return to the previous user (the one with ‘sudo’ privileges).

deactivate && exit

Step 11: Create Additional Directories for Custom Addons and Odoo Logs

Custom addons will be stored in the odoo13-custom-addons directory. Create it with this command:

sudo mkdir /opt/odoo/odoo13-custom-addons

The owner of the directory must be the odoo user:

sudo chown odoo: /opt/odoo/odoo13-custom-addons

Create an odoo13 directory to store Odoo log files:

sudo mkdir /var/log/odoo13

Create an empty log file:

sudo touch /var/log/odoo13/odoo.log

Make sure the odoo user is the owner of the directory and the log file:

sudo chown -R odoo: /var/log/odoo13/

Step 12 : Configure Your Odoo 13 Instance

The core preferences and settings go into the configuration file called odoo.conf.

We will use nano to create and open the file:

sudo nano /etc/odoo.conf

Copy the text below into the Odoo configuration file:

[options]

; This is the password that allows database operations:

admin_passwd = master_password

db_host = False

db_port = False

db_user = odoo

db_password = False

xmlrpc_port = 8069

; longpolling_port = 8072

logfile = /var/log/odoo13/odoo.log

logrotate = True

addons_path = /opt/odoo/odoo13/addons,/opt/odoo/odoo13-custom-addons

Make sure that you change master_password to something more secure. It’s your main Odoo password.

Note: If you are a SolaDrive customer and use one of our Odoo VPS Hosting services you can simply ask our expert Odoo specialists to change your Odoo password for you. We are available 24×7 via chat or ticket and will take care of your request immediately.

Save and close the config file when you’re finished.

Make sure the owner of the config file is the odoo user:

sudo chown odoo:odoo /etc/odoo.conf

Specify the file’s permissions:

sudo chmod 640 /etc/odoo.conf

Step 13: Create the systemd Configuration File

systemd is a service that allows applications to be run on the background as services. Let’s configure Odoo to do exactly that.

We use nano to create and open the Odoo 13 service configuration file:

sudo nano /etc/systemd/system/odoo13.service

Copy the text below into the file (no changes necessary):

[Unit]

Description=Odoo13

#Requires=postgresql-10.6.service

#After=network.target postgresql-10.6.service



[Service]

Type=simple

SyslogIdentifier=odoo13

PermissionsStartOnly=true

User=odoo

Group=odoo

ExecStart=/opt/odoo/odoo13-venv/bin/python3.6 /opt/odoo/odoo13/odoo-bin -c /etc/odoo.conf

StandardOutput=journal+console



[Install]

WantedBy=multi-user.target

Save and close the config file when you’re finished.

Step 14: Start Odoo and Activate the Service

Run Odoo 13 as a service:

sudo systemctl start odoo13.service

Enable the Odoo 13 service for it to always run (by default).

sudo systemctl enable odoo13.service

You have now successfully installed Odoo 13 on Ubuntu 20.x.

Step 15: Access the Odoo Graphical Interface

Enter the following URL into your browser:

http://server_IP:8069

Change server_IP to the IP address of the server.

If everything went well, you will be greeted with the Odoo 13 starting screen:
