Installing Redis 6 on Ubuntu 20.10

Redis is an open source, in-memory, data structure store that can be used as a cache, primary database and message broker. It is a multi-model database that supports search, graph, real-time streaming, analytics and many other use cases beyond that of a simple data store. With over 52,000+ GitHub stars, 20,000+ forks and over 500+ contributors, Redis is quite popular among the developers. Redis gives developers building applications the tools and information they need in a very efficient manner. Redis today can be deployed on-premises, across clouds, hybrid environments as well as over the Edge devices flawlessly.

Installing Redis on Linux is super easy. The easiest way to install Redis from source follow the below process:

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
