How to Install and Configure Redis & Redis-Server 5.0.5 on Ubuntu, Debian and Linux Mint

Redis, developed in 2009, is a flexible, open-source, key value data store. Following in the footsteps of other NoSQL databases, such as Cassandra, CouchDB, and MongoDB, Redis allows the user to store vast amounts of data without the limits of a relational database.

Additionally, it has also been compared to memcache and can be used, with its basic elements as a cache with persistence.
