集群简介
redis集群结构设计
数据存储设计
集群内部通讯设计
最多找两次就能找到！
redis集群(cluster)结构搭建
集群结构
- 配置服务器（3主3从）
- 建立通信（Meet）
- 分槽（Slot）
- 搭建主从（master-slave）
Cluster配置
6个节点全配置
开启集群
redis-cli -a 1234 --cluster create 192.168.135.10:6371 192.168.135.10:6372 192.168.135.10:6373 192.168.135.11:6374 192.168.135.11:6375 192.168.135.11:6376 --cluster-replicas 1
- –cluster-replicas 1 ：表示一个master连一个slave，如果改成–cluster-replicas 2表示一个master连2个slave

放与取数据
加一个-c的参数，这是专门用来操作cluster集群的
Cluster节点操作命令
