How to Install Redis Stack Server on the Latest Ubuntu

Redis Stack Server is a package that combines Redis, Redis Modules, RedisInsight, and RedisGears into a single installation. Redis Stack Server allows you to run Redis with advanced features and capabilities, such as search, graph, JSON, AI, and stream processing. Redis Stack Server also provides a graphical user interface for managing and monitoring your Redis instances. In this blog post, I will show you how to install Redis Stack Server on the latest Ubuntu using the official APT repository.

Prerequisites

Before you begin, you need to have the following:

• A system running the latest Ubuntu (22.04 Jammy Jellyfish at the time of writing, 23.10 has trouble with signed repository).
• A user account with sudo privileges.
• A stable internet connection.

Step 1: Add the Redis APT Repository

To install the latest stable version of Redis Stack Server, you need to add the official packages.redis.io APT repository to your system. This repository supports Debian Bullseye (11), Ubuntu Bionic (18.04), Ubuntu Focal (20.04), and Ubuntu Jammy (22.04) on x86 and arm64 processors.

To add the repository, follow these steps:

• Open a terminal and update the package index:

sudo apt update

• Install the curl and gnupg packages if they are not already installed:

sudo apt install curl gnupg

• Download and import the Redis GPG key:

curl -fsSL https://packages.redis.io/gpg | sudo gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg

• Add the Redis APT repository to your sources list:

echo "deb [signed-by=/usr/share/keyrings/redis-archive-keyring.gpg] https://packages.redis.io/deb $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/redis.list

Step 2: Install Redis Stack Server

Now that you have added the Redis APT repository, you can install Redis Stack Server using the apt command. To do so, follow these steps:

• Update the package index again:

sudo apt update

• Install Redis Stack Server:

sudo apt install redis-stack-server

• Confirm the installation by pressing Y when prompted.

The installation process will take some time and install all the components of Redis Stack Server, including Redis, Redis Modules, RedisInsight, and RedisGears. It will also create a systemd service for Redis Stack Server and start it automatically.

Step 3: Verify the Installation

To verify that Redis Stack Server is installed and running correctly, you can use the following methods:

• Check the status of the Redis Stack Server service:

sudo systemctl restart redis-stack-server
sudo systemctl status redis-stack-server

You should see an output similar to this:

● redis-stack-server.service - Redis Stack Server
     Loaded: loaded (/lib/systemd/system/redis-stack-server.service; enabled; vendor preset: enabled)
     Active: active (running) since Mon 2023-10-18 12:34:56 UTC; 5min ago
       Docs: 3
   Main PID: 1234 (redis-server)
      Tasks: 4 (limit: 2286)
     Memory: 81.4M
     CGroup: /system.slice/redis-stack-server.service
             └─1234 /usr/bin/redis-server 127.0.0.1:6379

Oct 18 12:34:56 ubuntu systemd[1]: Starting Redis Stack Server...
Oct 18 12:34:56 ubuntu systemd[1]: Started Redis Stack Server.

This indicates that the service is active and running.

• Connect to the Redis server using the redis-cli command:

redis-cli

You should see a prompt similar to this:

127.0.0.1:6379>

This indicates that you are connected to the Redis server.

• Run some Redis commands to test the functionality of the server and the modules. For example, you can run the following commands:

127.0.0.1:6379> set hello world
OK
127.0.0.1:6379> get hello
"world"
127.0.0.1:6379> json.set foo . '{"name":"bar"}'
OK
127.0.0.1:6379> json.get foo
"{\"name\":\"bar\"}"
127.0.0.1:6379> quit

These commands demonstrate how to use the basic Redis commands and the RedisJSON module. You can find more commands and examples in the Redis documentation.

The RedisInsight graphic user interface helps you visually browse and interact with Redis data.

• Browse, filter, and visualize Redis keys, perform CRUD operations, or delete keys in bulk. 
• Display data in pretty-print JSON, hexadecimal, MessagePack, and many other formats. Use friendly keyboard navigation. 
• Use the Tree view to group data and enhance the navigation.

RedisInsight installation downloads through the official page.

Frequent use commands

# redis server monitor
redis-cli monitor
127.0.0.1:6379> monitor

# find the redis data path
redis-cli config get dir
127.0.0.1:6379> config get dir

# turn off protected mode if redis is running in secure enviroment (behind firewall, dedicate non sharing network)
redis-cli config set protected-mode no
127.0.0.1:6379> config set protected-mode no
