Setting Up Redis CLI on Ubuntu: A Beginner’s Guide

Posted on by Noah Belkacem

Introduction

Redis CLI is a command-line interface that allows you to interact with Redis databases. It provides a simple and efficient way to manage and query Redis data. In this tutorial, we will walk you through the process of setting up Redis CLI on Ubuntu.

Prerequisites

Before we begin, make sure you have the following:

  • Ubuntu installed on your system
  • Root or sudo access

Step 1: Update System Packages

First, let’s update the system packages to ensure we have the latest versions:

sudo apt update
sudo apt upgrade -y

Step 2: Install Redis

Next, we need to install Redis on our Ubuntu system:

sudo apt install redis-server -y

Step 3: Verify Redis Installation

After the installation is complete, we can verify that Redis is running by checking its status:

sudo systemctl status redis-server

If Redis is running, you should see a message indicating that the service is active and running.

Step 4: Install Redis CLI

Now, let’s install Redis CLI:

sudo apt install redis-tools -y

Step 5: Connect to Redis Server

To connect to the Redis server using Redis CLI, use the following command:

redis-cli

This will open the Redis CLI prompt, where you can start interacting with the Redis server.

Step 6: Test Redis CLI

To test if Redis CLI is working correctly, let’s try a simple command. Type the following command in the Redis CLI prompt:

PING

If Redis CLI is set up correctly, you should see a response of “PONG”. This confirms that Redis CLI is able to communicate with the Redis server.

Frequently Asked Questions

Q: How can I check the version of Redis CLI?

To check the version of Redis CLI, you can use the following command:

redis-cli --version

This will display the version information of Redis CLI.

Q: Can I connect to a remote Redis server using Redis CLI?

Yes, you can connect to a remote Redis server by specifying the host and port using the following command:

redis-cli -h  -p

Replace with the IP address or hostname of the remote server, and with the Redis server port number.

Q: How can I authenticate with Redis CLI?

If your Redis server requires authentication, you can use the following command to authenticate with Redis CLI:

redis-cli -a

Replace with the actual password for your Redis server.

Conclusion

Congratulations! You have successfully set up Redis CLI on your Ubuntu system. You can now use Redis CLI to manage and query your Redis databases. Feel free to explore more Redis CLI commands and unleash the power of Redis!
