# Starting and stopping cluster

How to start and stop your Data Center Edition's cluster in SonarQube Server 2026.5.

{% hint style="info" %}
There is no way to perform actions on the cluster from a central app - all operations must be done manually on each node of the cluster.
{% endhint %}

## Start the cluster <a href="#start-cluster" id="start-cluster"></a>

To start a cluster, you need to follow these steps in order:

1. Start the search nodes.
2. Start the application nodes.

## Stop the cluster <a href="#stop-cluster" id="stop-cluster"></a>

To stop a cluster, you need to follow these steps in order:

1. Stop the application nodes.
2. Stop the search nodes.

## Start or stop a node <a href="#start-stop-node" id="start-stop-node"></a>

You can start or stop a single node in the same way as starting and stopping an instance using a single server. By default, it’s a graceful shutdown where no new analysis report processing can start, but the tasks in progress are allowed to finish.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.sonarsource.com/sonarqube-server/server-installation/data-center-edition/starting-stopping-cluster.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
