前言
Redis是一款流行的、开源的、基于内存的键值存储系统，以其卓越的速度和丰富多样的数据结构（如字符串、哈希、列表、集合、有序集合等）著称。它提供持久化、事务、发布/订阅、 Lua脚本等功能，广泛运用于缓存、实时计算、排行榜、会话存储等领域，有效提升了应用程序的性能和响应速度。

实例部署
1. 部署环境
Redis版本：5.0.8
内核版本3.10.0-1160.el7.x86_64
系统系统：CentOS Linux release 7.9.2009
2. 应用下载
3. 编译安装
（1）上传Redis压缩包到其中一台服务器上，解压编译，需提前安装好gcc-c+
tar -xf redis-5.0.8.tar.gzcdredis-5.0.8yum install gcc-c++makecdsrc/makeinstall![]()
（2）创建Redis实例目录，并把编译好的二进制文件复制到Redis的启动目录下
mkdir/data/product/redis01/{conf,bin,logs} -pcpredis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server redis-sentinel /data/product/redis01/bin/cp../redis.conf/data/product/redis01/conf/redis.conf.def（3）创建配置文件（以redis01为例）不同服务器和端口实例的需要调整配置的ip

构建集群
1.构建master节点
/data/product/redis01/bin/redis-cli --cluster create --cluster-replicas 0-aYWZL123456 192.168.43.51:7101192.168.43.52:7101192.168.43.53:7101
2. 查看masterid（指定slave需要用到masterid）
/data/product/redis01/bin/redis-cli -h 192.168.43.51 -p 7101 -a YWZL123456 cluster nodes
3.执行slave节点到指定的master节点上
/data/product/redis01/bin/redis-cli--clusteradd-node192.168.43.51:7102192.168.43.52:7101-aYWZL123456--cluster-slave--cluster-master-id90a8e289099f82413731d5ae1da5c16f79339c5c/data/product/redis01/bin/redis-cli--clusteradd-node192.168.43.52:7103192.168.43.51:7101-aYWZL123456--cluster-slave--cluster-master-id90a8e289099f82413731d5ae1da5c16f79339c5c/data/product/redis01/bin/redis-cli--clusteradd-node192.168.43.51:7103192.168.43.53:7101-aYWZL123456--cluster-slave--cluster-master-idab3b8211536292a533998aa3dffbf2d4dfd39d78/data/product/redis01/bin/redis-cli--clusteradd-node192.168.43.53:7103192.168.43.51:7101-aYWZL123456--cluster-slave--cluster-master-idab3b8211536292a533998aa3dffbf2d4dfd39d78/data/product/redis01/bin/redis-cli--clusteradd-node192.168.43.53:7102192.168.43.52:7101-aYWZL123456--cluster-slave--cluster-master-id95d7276bd52704742923541ce1fe17375c3ba9cd/data/product/redis01/bin/redis-cli--clusteradd-node192.168.43.52:7102192.168.43.53:7101-aYWZL123456--cluster-slave--cluster-master-id95d7276bd52704742923541ce1fe17375c3ba9cd

集群验证
1. 查看3个master是否对应指定的slave
/data/product/redis01/bin/redis-cli-h192.168.43.51-p7101 -aYWZL123456inforeplication/data/product/redis01/bin/redis-cli-h192.168.43.52-p7101 -aYWZL123456inforeplication/data/product/redis01/bin/redis-cli-h192.168.43.53-p7101 -aYWZL123456inforeplication
2. 在单台节点上插入数据查看是否同步（集群需要指定参数-c）
/data/product/redis01/bin/redis-cli-h192.168.43.53-p7101 -c-aYWZL123456setusernamezhangsangetusername
