Connecting with redis-cli

This guide explains how to establish a connection between  redis-cli and a Redis database instance. It walks through the necessary setup, configuration, and execution of a simple Redis command from the terminal. 
 Variables 
 Certain parameters must be provided to establish a successful connection to a Redis database. Below is a breakdown of each required variable, its purpose, and where to find it. Here’s what each variable represents: 
 
 
 
 
 Variable 
 
 
 Description 
 
 
 Purpose 
 
 
 
 
 
 
 HOST 
 
 
 Redis hostname, from the Elestio service overview page 
 
 
 The address of the server hosting your Redis instance. 
 
 
 
 
 PORT 
 
 
 Port for Redis connection, from the Elestio service overview page 
 
 
 The network port used to connect to Redis. The default port is 6379. 
 
 
 
 
 PASSWORD 
 
 
 Redis password, from the Elestio service overview page 
 
 
 The authentication key required to connect securely to Redis. 
 
 
 
 
 These values can usually be found in the Elestio service overview details as shown in the image below, make sure to take a copy of these details and use them in the command moving ahead. 
 
 Prerequisites 
 Install redis-cli 
 Check if redis-cli is installed by running: 
 redis-cli --version 
 If not installed, you can install it via: 
 
 
 macOS : 
 
 
 brew install redis 
 
 
 Ubuntu/Debian : 
 
 
 sudo apt install redis-tools 
 
 
 Windows : 
 Use Windows Subsystem for Linux (WSL) or download a Redis CLI binary. 
 
 
 Command 
 Once all prerequisites are set up, open the terminal or command prompt and run the following command: 
 redis-cli -h HOST -p PORT -a PASSWORD 
 Replace HOST , PORT , and PASSWORD with the actual values from your Elestio Redis service. If the connection is successful, the terminal will display a Redis prompt like this: 
 HOST:PORT> 
 You can then run a simple command to test the connection: 
 set testKey "Hello Redis"
get testKey 
 Expected output: 
 "Hello Redis" 
 If the connection is successful, the terminal will display output similar to: 
 "Hello Redis"
