Running Redis Locally
Redis can be installed locally, run in containers, or consumed as a managed cloud service. For learning, the two most important ideas are the Redis server process and the Redis command-line client.
Basic Commands
SET greeting "hello"
GET greeting
DEL greetingThese commands already show the basic key-value workflow: store a value, retrieve it, and remove it.
redis-cli
redis-cli is a direct way to inspect, test, and debug Redis behavior. Even developers who mainly use Redis through application code should know the CLI because it is useful for verification and troubleshooting.
Server Process Thinking
Redis is a separate service process, not just a library. Applications connect to it over a network interface. This means connection handling, environment configuration, and operational visibility matter in real deployments.
Practical Example
A developer building an API may keep Redis running locally, set test keys with redis-cli, and verify whether the application is correctly storing and reading cache entries during development.
