This document provides instructions for installing Redis and configuring a Redis cluster in Linux. It explains how to download and compile Redis, create configuration files for 6 nodes using different ports and filenames, start each Redis server using its configuration file, and use the redis-cli command to create a cluster with 1 replica across the 6 nodes. Once created, information about node 1 can be viewed by connecting to it on port 7001 with redis-cli.
