Installing Dependencies Overview

Install the prerequisite software: Node.js, Redis, and MongoDB. Links to additional documentation resources have been provided below.

• Node.js
• Redis
• MongoDB

Node.js must be installed on the same server as IAP. Redis and MongoDB should be installed on separate servers from IAP in a production deployment, but alternatively can be installed on the same server as IAP for an all-in-one type development deployment. If a shared token Redis instance exists, it can be used rather than a second Redis instance. See the High Availability Architecture section for production deployment options.

Before beginning the installation process, issue the following command on the target server to ensure any package repositories it uses are up to date:

sudo yum -y update
