NoSQL database case combat--Redis password protection

Preface

This environment is based on the Centos 7.8 system to build a Redis learning environment. For
specific construction, please refer to Redis-5.0.9 Environment Deployment

Set a password for the redis server, so that the client connection to the redis service requires password authentication, which can make your redis service more secure.
