How to install Redis on Ubuntu

In this tutorial we will learn to install Redis on Ubuntu.

Step #1: Update

Before we start installing Redis on our Ubuntu machine let us go ahead and update the packages.

Note! In the above command we are using sudo so, you will be prompted to enter your password.

If any package needs an upgrade then run the following command.

PONG

To exit redis-cli run the following command.

127.0.0.1:6379> exit
