Redis 3.2.3: 集群3哨兵模式

简介

Redis是一个使用ANSI C编写的开源、支持网络、基于内存、可选持久性的键值对存储数据库。从2015年6月开始，Redis的开发由Redis Labs赞助，而2013年5月至2015年6月期间，其开发由Pivotal赞助。^[1]在2013年5月之前，其开发由VMware赞助。^[2]^[3]根据月度排行网站DB-Engines.com的数据显示，Redis是最流行的键值对存储数据库。^[4]

前言

本篇主要介绍Redis的集群部署，采用三台机器，一主两从，三台均为哨兵。

192.168.10.6 Redis主， Redis-Sentinel

192.168.10.7 Redis从， Redis-Sentinel

192.168.10.8 Redis从， Redis-Sentinel

Redis-master（192.168.10.6上的配置）
