Redis, which stands for “remote dictionary server,” is a key-value store that stores data as key-value pairs. Redis is a NoSQL database, meaning it does not have tables, rows and columns like in MySQL and Oracle databases. It does not use INSERT, SELECT, UPDATE and DELETE. Instead of this, Redis uses data structures to store data. It uses five primary data structures including Strings, Lists, Sets, Sorted Sets, and Hashes, as well as three extra data structures including bitmaps, hyperloglogs and geospatial indexes. One of the most important features of Redis is that it is an in-memory database, meaning it keeps the data in memory, making it super-fast. However, Redis also has options to write the data to the disk.

In this tutorial, we will show you how to install and secure Redis on Ubuntu 18.04.
