Redis, or Remote Dictionary Server, is a free and open-source in-memory data structure store and caching system. Redis stores the required data in memory, allowing rapid read and write operations.

As a result, it is often employed for caching frequently accessed data, real-time analytics, and managing session states due to its speed and versatility.

One significant way to interact with a cluster server is using the Redis CLI. The Redis CLI is a command-line utility that connects and manages the Redis server using simple and intuitive commands.

Installing Redis CLI - Debian/Ubuntu

If you are using Ubuntu or any other Debian-based repository, you can quickly install the Redis CLI by using the official repositories as shown in the command below:

$ sudo apt-get update
$ sudo apt-get install redis-tools -y

This should download the Redis Tools and install them on your system. This should include the Redis CLI.

You can also install them using PPAs. Start by adding the PPA repository using the command shown below:

sudo add-apt-repository ppa:redislabs/redis

Next, update the apt meta using the command:

sudo apt update

Finally, install the tools:

sudo apt-get install redis-tools -y

Pinging the Redis Server

Once you have installed the Redis CLI, you can quickly ping the Redis server to ensure that the server is running by using the command:

$ redis-cli ping

If the server is running, it should return the string PONG, telling you you can connect and start executing commands on the server.

Conclusion

This tutorial taught you how to quickly install the Redis CLI and the associated tools in your Debian-based distribution using PPAs or the official repository.
