by On this article we will discuss how to install Odoo version 14 Community edition on Linux CentOS 8. We will use Odoo binary source from Odoo official GitHub repository and Python virtual environment. Also we will be using Odoo default webserver, PostgreSQL 13 and Nginx as a reverse proxy for security reason.
Introduction
Odoo is a suite of business management software tools that ships with various business applications including: CRM, e-Commerce, billing, accounting, manufacturing, warehouse, project management, inventory management and much more, all seamlessly integrated.
The Odoo Community version is a libre software, licensed under the GNU LGPLv3, while the Enterprise version has proprietary extra features and services. The source code for the framework and core ERP modules is curated by the Belgium-based Odoo S.A. Odoo is available for both on-premise and ready to use SaaS environment. On this article we will discuss how to install Odoo on Linux CentOS 8 operating system.
Odoo Installation on CentOS 8
We will use the latest stable version of Odoo, version 14.0 which was released on October 2, 2020. The binary file was hosted on Odoo official GitHub repository. The installation process will consist of several stages, namely:
- Prerequisites
- Install and Configure PostgreSQL
- Install Wkhtmltopdf
- Install and Configure Odoo 14
- Testing Odoo 14 Installation
Prerequisites
Odoo consists of several applications that are put together in a seemless integrated bundle, so it requires several supporting tools or libraries to make the application run smoothly.
Update CentOS 8 system
Before we add new applications or new software to our system, it is better if we update the system first. On CentOS 8, this task can be done by submitting command line : sudo dnf update.
[ramans@localhost ~]$ sudo dnf update
[sudo] password for ramans:

Install Prerequisites Tools
Odoo is written in Python, JavaScript and XML. The first step is to install Python 3 and all appropriate libraries and tools required to build Odoo. On this section we will install several dependcies tools, such as : Python 3, Git, GCC and other other libraries.

Install and Configure PosrgreSQL
Odoo is using PosrgreSQL as default database. The PostgreSQL installation on CentOS 8 has been discussed on previous article, PostgreSQL (Postgres) Installation on CentOS 8. At this section we will check if the PostgreSQL daemon is running properly by submitting command line : sudo systemctl status postgresql-13.
ramans@localhost ~]$ sudo systemctl status postgresql-13

For Odoo application purpose, we will create a new database user called as odoo14, by submitting command line : sudo su - posrgres -c "createuser -s odoo14"
[ramans@localhost ~]$ sudo su - postgres -c "createuser -s odoo14"
Install Wkhtmltopdf
We require wkhtmltopdf application to print PDF reports in Odoo. wkhtmltopdf is an open source (LGPLv3) and much effective command-line shell utility that enables user to convert any given HTML (Web Page) to PDF document or an image (jpg, png, etc). The installation of wkhtmltopdf has been discussed on How to Install wkthmltopdf and wkhtmltoimage on CentOS 8 article.
On this section we will query its version to ensure if the wkhtmltopdf tools has been installed on our CentOS system, by submitting command line : wkhtmltopdf -- version and wkhtmltoimage --version
[ramans@localhost ~]$ wkhtmltopdf --version wkhtmltopdf 0.12.6 (with patched qt) [ramans@localhost ~]$ wkhtmltoimage --version wkhtmltoimage 0.12.6 (with patched qt)
Install and Configure Odoo 14
At this section we will install the Odoo version 14 community edition where the binary source is located on the Odoo Github official. We will clone it to our system by using a new system user called as odoo14.
Creating a system user
So for the first time we have to create a new user first, by submitting command line : sudo useradd -m -U -r -d /opt/odoo14 -s /bin/bash odoo14.
[ramans@localhost ~] sudo useradd -m -U -r -d /opt/odoo14 -s /bin/bash odoo14.
Copy Odoo Binary files from GitHub
On this step we will clone Odoo binary files from Odoo official GitHub repository by using odoo14 user and locate it to the /opt/odoo14 directory.
ramans@localhost ~]$ sudo su - odoo14 [sudo] password for ramans: [odoo14@localhost ~]$ git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 /opt/odoo14/odoo Cloning into '/opt/odoo14/odoo'… warning: redirecting to https://github.com/odoo/odoo.git/ remote: Enumerating objects: 30175, done. remote: Counting objects: 100% (30175/30175), done. remote: Compressing objects: 100% (23201/23201), done. remote: Total 30175 (delta 9375), reused 18559 (delta 5862), pack-reused 0 Receiving objects: 100% (30175/30175), 130.66 MiB | 705.00 KiB/s, done. Resolving deltas: 100% (9375/9375), done. Updating files: 100% (26647/26647), done.
Odoo 14 Installation on CentOS 8
After cloning Odoo binary files, then we will do the installation inside Pyhon virtual environment. We will create Python virtual environment first for Odoo installation, by submitting command line :
[odoo14@localhost ~]$ cd /opt/odoo14 [odoo14@localhost ~]$ python3 -m venv venv [odoo14@localhost ~]$ source venv/bin/activate (venv) [odoo14@localhost ~]$
After entering inside Python virtual environment, the we will install the Odoo 14 Community edition on the system, by submitting command line : pip3 install -r odoo/requirements.txt.
(venv) [odoo14@localhost ~]$ pip3 install -r odoo/requirements.txt
After Odoo installation is completed done, then we will exit from Python virtual environment by submitting command line deactivate.
(venv) [odoo14@localhost ~]$ deactivate
The next step is creating a new directory inside /opt/odoo14, called as odoo-custom-addons. The directory will be used to hold the addons_path parameter to define a list of directories where Odoo searches for modules. Then exit from odoo14 user to the sudo user.
[odoo14@localhost ~]$ mkdir /opt/odoo14/odoo-custom-addons [odoo14@localhost ~]$ exit logout [ramans@localhost ~]$
Creating Odoo configuration file
After returning to the sudo user, then we will create Odoo configuration file which is locate on the /etc/odoo14.conf. The conten of configuration file is as follow :
[ramans@localhost ~]$ sudo vi /etc/odoo14.conf
The conten of /etc/odoo14.conf file :
[options] admin_passwd = otod1g1net_oke db_host = False db_port = False db_user = odoo14 db_password = False addons_path = /opt/odoo14/odoo/addons, /opt/odoo14/odoo-custom-addons
Creating Odoo Systemd Unit File
On this step, we will create an Odoo systemd unit file by creating a new file /etc/systemd/system/odoo14.service.
[ramans@localhost ~]$ sudo vi /etc/systemd/system/odoo14.service
[Unit] Description=Odoo14 Requires=postgresql-13.service After=network.target postgresql-13.service [Service] Type=simple SyslogIdentifier=odoo14 PermissionsStartOnly=true User=odoo14 Group=odoo14 ExecStart=/opt/odoo14/venv/bin/python3 /opt/odoo14/odoo/odoo-bin -c /etc/odoo14.conf StandardOutput=journal+console
/etc/systemd/system/odoo14.serviceAfter creating Odoo systemd file, then we have notify if there was a new unit file already exists, by submitting command line : sudo systemctl daemon-reload. Then start and enable the service. To ensure if the service is running, we also query its service by submitting command line sudo systemctl status odoo14.
[ramans@localhost ~]$ sudo systemctl enable --now odoo14
[ramans@localhost ~]$ sudo systemctl status odoo14

Testing Odoo 14 Installation
So far, the Odoo installaton is completed done. On this section we will test the installation by using web browser. We will hit the http://<your_domain_or_IP_address>:8069.
Conclusion
So far, the Odoo 14 installation on CentOS 8 has been completed done successfully. On this tutorial is less of NginX installation and configuration, but as the basic function of Odoo it has been fulfilled. On the next time, we will discuss about using Odoo. Have a great day.
