Installation of Redis on Ubuntu - (Redis Tutorial)

Redis is an open-source, in-memory data store that can be used as a database, cache, and message broker. In this tutorial, we will discuss how to install Redis on Ubuntu. We will cover the syntax, example, output, explanation, use, important points, and summary of installing Redis on Ubuntu.

Syntax

$ sudo apt update
$ sudo apt install redis-server

Example

Let's go through an example of how to install Redis on Ubuntu:

1. Open terminal in Ubuntu by pressing Ctrl + Alt + T or by searching for the terminal in the applications menu.

2. Run the following command to update the package index:

   $ sudo apt update
   

3. Run the following command to install Redis:

   $ sudo apt install redis-server
   

4. Wait for the installation to complete.

Processing triggers for systemd (245.4-4ubuntu3.13) ...
Processing triggers for man-db (2.9.1-1) ...

Explanation

In the example above, we used the apt package manager to install Redis. The apt update command updates the package index, and the apt install redis-server command installs Redis.

Use

After installing Redis, you can use it as a database, cache, or message broker. Redis provides a number of data structures, including strings, hashes, sets, and sorted sets, that can be used to store data.

You can also use Redis as a cache, where it stores frequently accessed data in memory to reduce access time. Redis has built-in support for expiring keys, which ensures that data is automatically deleted from the cache after a certain amount of time.

Redis can also be used as a message broker. Redis provides support for Pub/Sub architecture, where publishers send messages to channels, and subscribers receive messages from those channels.

Important Points

• You must have root access or sudo privileges to install Redis on Ubuntu.
• Installing Redis using apt package manager is the easiest and recommended way to install Redis on Ubuntu.
• After installing Redis, you can use it as a database, cache, or message broker.
