Installation & First steps

This is just a prototype, do not yet use in production.

System requirements

NethServer 8 can be deployed on one ore more nodes in a cluster scenario.

Supported distributions:

  • CentOS Stream 9
  • Debian 11 (bullseye)

Hardware requirements for a single node installation:

  • 2 vCPU/cores
  • 2GB RAM
  • 20GB disk

More nodes can be added later. When adding a new node, you should use similar hardware and the same distribution installed on the leader node.

Always install NethServer 8 on a clean server machine, do not install it on a desktop.

Core installation

Pick your preferred distribution between supported ones and make sure it’s up to date. Also ensure that the system firewall is not blocking any connection.

First, ensure curl is installed:

  • for Debian: apt-get install -y curl
  • for CentOS: dnf install -y curl

Start the installation procedure as root:

curl | bash

At the end of the install script the UI is available at https://<server_ip_or_fqdn>/cluster-admin/:

  • default user: admin
  • default password: Nethesis,1234

Some configuration tasks can be completed also by invoking additional commands: follow on-screen instructions printed by

Run either new cluster initialization (create-cluster) or joining an existing cluster (join-cluster).

Install custom images

Developers may prefer to run with one or more images from a development branch or alternative registries.


Install customization

The install script also accepts the following environment variables:

  • TESTING: override testing flag inside the default repository. It can be 0 (disabled) or 1 (enabled), default is 0
  • REPMOD: override default software repository URL, it could be something like https://mycustomrrepo.server.test/repomd
  • ADMIN_PASSWORD: override default admin password


Core applications installed by default:

Other available core applications:

Application installation

Applications can be installed directly from the user interface.

If you prefer the command line, use the add-module command:

add-module <module> <node_id>

The above command will try to install the latest stable version of the module.

Example to install Dokuwiki on node 1:

add-module dokuwiki 1

You can also install an image which is not still available inside the repository by using its URL.

Example to install Dokuwiki directly from the image registry:

add-module 1

Many applications need a configuration step after install, for more info, please refer to the README of each application.

The script attempts to stop and erase core components and additional modules. Handle it with care because it erases everything under /home/* and /var/lib/nethserver/*!

bash /var/lib/nethserver/node/
