Redis 集群介绍

Redis 三主三从集群是提升数据库系统可用性、容错性和性能的关键部署模式。它由三个主节点处理读写请求，三个从节点复制主节点数据，确保数据高可用与冗余。通过自动故障转移机制，从节点能在主节点故障时自动接管，保障服务连续性。此外，读写分离与负载均衡策略进一步优化了系统性能，适用于电商、社交网络和实时数据分析等高要求场景。

集群的核心优势在于其高效的数据复制与同步机制，从节点无缝复制主节点数据，不阻塞主节点处理流程。同时，当主节点故障时，系统能迅速自动完成故障转移，无需人工干预，极大提升了系统的稳定性和可靠性。

Redis 三主三从集群以其卓越的高可用性、容错能力和性能优化，成为复杂应用场景下数据存储与访问的首选方案。通过合理配置与部署，它能有效满足各类业务对数据存储的高要求，确保数据的安全、可靠与高效访问。

初始化 redis 集群

放行端口 6379，6380，6381，6382,6383,6384

查看 Redis 主机 IP 地址

[root@flexusx-251f~]# docker inspect redis-master1 |grep-iipadd"SecondaryIPAddresses":null,"IPAddress":"","IPAddress":"172.27.0.2",[root@flexusx-251f~]# docker inspect redis-master2 |grep-iipadd"SecondaryIPAddresses":null,"IPAddress":"","IPAddress":"172.27.0.3",[root@flexusx-251f~]# docker inspect redis-master3 |grep-iipadd"SecondaryIPAddresses":null,"IPAddress":"","IPAddress":"172.27.0.7",[root@flexusx-251f~]# docker inspect redis-slave1 |grep-iipadd"SecondaryIPAddresses":null,"IPAddress":"","IPAddress":"172.27.0.6",[root@flexusx-251f~]# docker inspect redis-slave2 |grep-iipadd"SecondaryIPAddresses":null,"IPAddress":"","IPAddress":"172.27.0.4",[root@flexusx-251f~]# docker inspect redis-slave3 |grep-iipadd"SecondaryIPAddresses":null,"IPAddress":"","IPAddress":"172.27.0.5",

进入其中一个主节点的容器内部

[root@flexusx-251f~]# docker exec -itredis-master1 /bin/bash root@04c85ab05c71:/data#

注意将 ip 修改为自己的容器 ip，端口对应之前创建的节点 port

•在使用 redis-cli --cluster create命令创建 Redis 集群时，Redis 会自动根据提供的节点数量和 --cluster-replicas 1的参数来分配主节点和从节

[root@flexusx-251f~]# docker exec -itredis-master1 /bin/bash root@04c85ab05c71:/data#redis-cli --clustercreate 172.27.0.2:6379 172.27.0.3:6379 172.27.0.7:6379 172.27.0.6:6379 172.27.0.4:6379 172.27.0.5:6379 --cluster-replicas1

当出现提示“Can I set the above configuration? (type 'yes' to accept)：”的时候，输入 yes 即可；

这样我们的三主三从就部署成功了
