This script will run on each of the servers to validate Red Hat subscription and install basic tools. If you are new to automation scripts and Git repositories this may seem a bit weird or uneasy to trust a script, for those that would like to see the scripts and what they do before you run them please follow these links:

(the Enterprise option) is run by Co-Founders Ofer Bengal (CEO) and Yiftach Shoolman (CTO) with Salvatore Sanfilippo as lead open source developer.

Redis.IO (the Open Source option) is run by Salvatore Sanfilippo with the help of sponsors.

What this means is that you can use it for free in your projects or you can pay for premium service and support. While there is an enterprise option, Redis is open source. Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster. It supports data structures such as strings, hashes, lists, sets, and sorted sets with range queries, bitmaps, hyperloglogs and geospatial indexes with radius queries. Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. Redis, a database benchmarked () as the world’s fastest, reduces application complexity, simplifies development, accelerates time to market and provides unprecedented flexibility to developers with its visionary data structures and modules.

In short, Redis is three or more server operational database cluster that is used for various tasks. While this code is tested, it is suggested to build in a development environment first. Much of this guide will work with a tested code stored in GitLab ( ) to make it easier to build the cluster. In our three servers cluster, we will have two Redis servers with one Redis Sentinel with HAProxy to assist the Sentinel. While you can have more than three servers in a Redis cluster for the sake of simplicity, we will cover setting up a three server Redis cluster.

This guide will walk you through both in a way that will hopefully be easy to follow and be easy to repeat in the future. First, if you don’t know what Redis is you are probably thinking, “What is this weird named thing and what do I need to do”. So, you’ve been told you need to build a Redis Server Cluster.
