2.6简介以及环境规划
在Redis6.x 版本中主要增加了多线程的新特性，多线性对于⾼并发场景是⾮常有必要的。

多线程IO 重新设计了客户端缓存功能
RESP3协议
⽀持SSL
ACL 权限控制
提升了RDB ⽇志加载速度
发布官⽅的Redis 集群代理模块 Redis Cluster proxy
Redis Cluster 集群原理可以查看之前发布的⽂章。

slave—>6703的master Reids 集群采⽤三主三从交叉复制架构，由于服务器数量有限，在⼀台机器中模拟出集群的效果，在实际⽣产环境中，需要准备三台机器，每台机器中分别部署两台Redis 节点，⼀主⼀
从，交叉备份。

2.⼆进制安装Redis 程序
2.1.⼆进制安装redis6.2.6
123456
1.下载reids [root@k8s-master1 /data/]# wget https://download.redis.io/releases/redis-6.
2.6.tar.gz 2.解压并安装redis
[root@k8s-master1 /data/]# tar xf redis-6.2.6.tar.gz
[root@k8s-master1 /data/]# cd redis-6.2.6
[root@k8s-master1 /data/redis-6.2.6]# make 2.2.创建Reids Cluster 集群⽬录

3.配置Redis Cluster 三主三从交叉复制集群
3.1.准备六个节点的redis 配置⽂件
redis6.2.6版本配置⽂件所有内容如下，主要配置带注释的⾏。

6701、6702、6703节点为主节点，6704、6705、6706节点为从节点。

6704复制6703的主节点、6705复制6701的主节点、6706复制6702的主节点。

架构图如下：
