Introduction

This document describes how to deploy Redis on a server running CentOS or openEuler, including single-instance deployment, master/slave replication deployment, and cluster deployment.

Select a Redis deployment mode based on the actual service requirements and system environments.

• For small-scale applications or simple requirements, select single-instance deployment.
• For read/write splitting and data backup and restoration scenarios, select master/slave replication deployment.
• For high concurrency, large data volume, and distributed storage scenarios, select cluster deployment.

Redis is an open source in-memory key-value database system written in ANSI C. It supports multiple data structures, such as strings, hash, lists, sets, and sorted sets, and provides APIs in multiple languages.
