Prerequisites

Platform supported

Check the software requirements

Nodeum supports the RHEL Family, Rocky Family and AlmaLinux Family.

Hardware

Nodeum software can be installed on a physical server, a virtual machine, or within a Docker Container.

Learn more about the hardware requirement.

The installation is performed with an Ansible Playbook or a Docker Image.

Before the deployment

• Check the DNS Resolution

• Verify that the server time is correctly configured.

• For Ansible, it's required to deploy Ansible 2.15 and Python 3.9

• For Docker, it's required to deploy Docker Engine. Podman is not compatible yet as it doesn't support fluentd driver.

How to install Python 3.9 ?

For each server in the cluster, uninstall any existing Python installations and install the correct version.

$ pip uninstall pip
$ yum remove python3
$ yum install python39
$ pip3 install --upgrade pip

or

$ yum install pip
$ pip install --upgrade pip

For a multi-node deployment, Python installation and pip3 upgrade must be performed

How to install Ansible ?

Run the Ansible playbooks from the node where they are installed.

$ pip3 install ansible

or

$ pip install ansible
