Prepare your Rocky Linux Server
By using a ssh client, login to your Rocky Linux server as root user.
Set a hostname and local dns resolution for your Linux machine by executing following commands.
# hostnamectl set-hostname odoo-01.centlinux.com
# echo "192.168.88.128 odoo-01 odoo-01.centlinux.com" >> /etc/hosts
As per best practice, you should update software packages in your Linux distribution before installing a new software.
Execute following dnf command at bash prompt to update your software packages.
# dnf update -y
If the above command updates software packages related to Linux kernel, then reboot your operating system before moving forward in this Linux tutorial.
# reboot
After reboot, verify the versions of software that are being used in this configuration guide.
# cat /etc/rocky-release Rocky Linux release 9.1 (Blue Onyx) # uname -r 5.14.0-162.18.1.el9_1.x86_64 # python -V Python 3.9.14
Install Odoo 16 Prerequisites
During the installation of Odoo, several additional software packages are required to ensure its proper functioning. These supporting packages are readily available in the standard yum repositories of your Linux distribution. To install them, you can use the versatile dnf command, which streamlines the process of fetching and setting up these dependencies.
These packages include essential tools, libraries, and utilities that Odoo relies on for optimal performance and compatibility with your system. By installing these dependencies beforehand, you can avoid potential issues during the Odoo setup and ensure a smooth and successful installation process.

Odoo ERP uses PostgreSQL database as it’s backend data store.
If you have already setup a PostgreSQL database server, then you can use the same here. Otherwise, you may also install PostgreSQL on the same Rocky Linux 9 server.
PostgreSQL server is available in standard yum repositories. Therefore, execute dnf command to install it.
# dnf install -y postgresql-server
Execute following Linux command to initialize PostgreSQL database server.
# postgresql-setup --initdb --unit postgresql * Initializing database in '/var/lib/pgsql/data' * Initialized, logs are in /var/lib/pgsql/initdb_postgresql.log
Enable and start PostgreSQL database service.
# systemctl enable --now postgresql Created symlink /etc/systemd/system/multi-user.target.wants/postgresql.service → /usr/lib/systemd/system/postgresql.service.
Create a database user for Odoo business suite.
# su - postgres -c "createuser -s odoo"
Install WKHTMLTOX on Linux
wkhtmltox is a powerful, free, and open-source command-line tool designed for converting HTML documents into PDF or other widely used formats. One of its key advantages is that it operates in a fully headless mode, meaning it does not require a graphical display or display-related services to function. This makes it an excellent choice for server environments where GUI dependencies are undesirable or unavailable.
To get started, you can either download the prebuilt RPM package for wkhtmltox from their official download page or obtain the source code by cloning the official wkhtmltox repository on GitHub. Both options provide flexibility depending on your system requirements and installation preferences.
To download the wkhtmltox RPM package quickly and efficiently, execute the following commands on your Linux terminal. This method ensures you have the correct version tailored to your operating system.
# cd /tmp # wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-2/wkhtmltox-0.12.6.1-2.almalinux9.x86_64.rpm ...

Create a dedicated Linux user specifically for managing the Odoo business suite. This user will not be used for authentication purposes within the Odoo software itself, meaning it won’t have any login capabilities for accessing the Odoo application.
Instead, the primary role of this user is to own and manage the Odoo software files and processes, ensuring that the system runs with proper permissions and security. By assigning the ownership of Odoo files to this separate user, you help isolate the Odoo environment from other system users, which enhances security and simplifies system administration.
# useradd -r -m -U -s /bin/bash -d /opt/odoo odoo
Switch to odoo user and clone the odoo repository from GitHub. Here, we are using “–branch 16.0” because Odoo 16 is the latest version at the time of this writing. You can use a different numbers if you wish to install other versions of Odoo.
# su - odoo $ git clone https://www.github.com/odoo/odoo > --depth 1 > --branch 16.0 > /opt/odoo/odoo Cloning into '/opt/odoo/odoo'... warning: redirecting to https://github.com/odoo/odoo.git/ remote: Enumerating objects: 38697, done. remote: Counting objects: 100% (38697/38697), done. remote: Compressing objects: 100% (30045/30045), done. remote: Total 38697 (delta 11040), reused 25777 (delta 7432), pack-reused 0 Receiving objects: 100% (38697/38697), 149.72 MiB | 480.00 KiB/s, done.
