# Setup

To set up a new Cluster node, you should follow these steps:

## Network it

Do the standard steps to add new entries for a node (or block of nodes) to DHCP and DNS.

{% content-ref url="/pages/-LKyHNaVNeKK4jQQx1Mw" %}
[DNS](/technologies/networking/dns.md)
{% endcontent-ref %}

{% content-ref url="/pages/-LMyKcsuAHkSR0WSwn3h" %}
[DHCP](/technologies/networking/dhcp.md)
{% endcontent-ref %}

Also make sure the switches/routers/cables are set up right.

## Install Ubuntu

The preferred method is to use Netboot, but a regular Ubuntu install stick works as well. If installing from an USB stick make sure your hostname matches the one specified in DNS/DHCP.

## Setup SSH

See [SSH Setup](#setup-ssh) page to learn more on how to setup SSH for the clusters.

## Run the Ansible play

First, make sure you add the node to an existing/new host group that has the `cluster` role. Then, you can just run `ansible-playbook`, sit back, kick your feet up, and wait for the install to finish.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.tjhsst.edu/services/cluster/setup.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
