# Configuring an ABS cluster

## About this task

To configure an API Behavioral Security (ABS) cluster:

## Steps

1. [Install MongoDB in a replica set](../installing_pingintelligence_for_apis/pingintelligence_abs_engine_installation.html)

2. [Connect ABS to MongoDB](../installing_pingintelligence_for_apis/pingintelligence_connect_abs_to_mongodb.html)

3. To create an ABS cluster, add an ABS node and connect it to MongoDB primary node.

   |   |                                                                                                                            |
   | - | -------------------------------------------------------------------------------------------------------------------------- |
   |   | Since ABS forms a stateless cluster, the information of all the nodes in the cluster is fetched by ABS nodes from MongoDB. |

4. To scale down ABS cluster, [stop](pingintelligence_starting_stopping_abs.html) the ABS node that you wish to remove from the cluster.

   1. Edit the `abs.properties` file to remove MongoDB Internet Protocol (IP) *(tooltip: \<div class="paragraph">
      \<p>The method by which data is sent across the internet from the source host to the destination host.\</p>
      \</div>)* address.
