Redis-Cluser 架构设计
- Redis-Cluser 采纳无核心构造,每个节点都保留数据和整个集群状态,各个节点之间相互链接
- 节点间采纳 ping-pong 机制互联,外部应用二进制协定传输优化速度和带宽
- Redis-Cluser 会把所有物理节点映射到 0 -16383 个 slot 上
- Redis 集群预分好 16384 个桶,当须要在 Redis 集群中搁置一个 key-value 时,依据 CRC16(key) mod 16384 的值,决定将一个 key 放到哪个桶中
-
部署 Redis-Cluser 3 节点 (一个正本)
- redis 配置
daemonize yes port 7006 cluster-enabled yes cluster-config-file "nodes.conf" cluster-node-timeout 15000 appendonly yes protected-mode no bind 0.0.0.0 masterauth "westos" requirepass westos
- 启动 redis 执行集群创立
redis-cli --cluster create 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006 --cluster-replicas 1
