Redis 集群介紹

Redis 三主三從集群是提升數據庫系統可用性、容錯性和性能的關鍵部署模式。它由三個主節點處理讀寫請求，三個從節點復制主節點數據，確保數據高可用與冗余。通過自動故障轉移機制，從節點能在主節點故障時自動接管，保障服務連續性。此外，讀寫分離與負載均衡策略進一步優化了系統性能，適用于電商、社交網絡和實時數據分析等高要求場景。

集群的核心優勢在于其高效的數據復制與同步機制，從節點無縫復制主節點數據，不阻塞主節點處理流程。同時，當主節點故障時，系統能迅速自動完成故障轉移，無需人工干預，極大提升了系統的穩定性和可靠性。

Redis 三主三從集群以其卓越的高可用性、容錯能力和性能優化，成為復雜應用場景下數據存儲與訪問的首選方案。通過合理配置與部署，它能有效滿足各類業務對數據存儲的高要求，確保數據的安全、可靠與高效訪問。

初始化 redis 集群

放行端口 6379，6380，6381，6382,6383,6384

查看 Redis 主機 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",

進入其中一個主節點的容器內部

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

注意將 ip 修改為自己的容器 ip，端口對應之前創建的節點 port

?在使用 redis-cli --cluster create命令創建 Redis 集群時，Redis 會自動根據提供的節點數量和 --cluster-replicas 1的參數來分配主節點和從節

[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

當出現提示“Can I set the above configuration? (type 'yes' to accept)：”的時候，輸入 yes 即可；
