Redis 集群介紹

Redis 三主三從集群是提升數(shù)據(jù)庫系統(tǒng)可用性、容錯(cuò)性和性能的關(guān)鍵部署模式。它由三個(gè)主節(jié)點(diǎn)處理讀寫請求，三個(gè)從節(jié)點(diǎn)復(fù)制主節(jié)點(diǎn)數(shù)據(jù)，確保數(shù)據(jù)高可用與冗余。通過自動故障轉(zhuǎn)移機(jī)制，從節(jié)點(diǎn)能在主節(jié)點(diǎn)故障時(shí)自動接管，保障服務(wù)連續(xù)性。此外，讀寫分離與負(fù)載均衡策略進(jìn)一步優(yōu)化了系統(tǒng)性能，適用于電商、社交網(wǎng)絡(luò)和實(shí)時(shí)數(shù)據(jù)分析等高要求場景。

集群的核心優(yōu)勢在于其高效的數(shù)據(jù)復(fù)制與同步機(jī)制，從節(jié)點(diǎn)無縫復(fù)制主節(jié)點(diǎn)數(shù)據(jù)，不阻塞主節(jié)點(diǎn)處理流程。同時(shí)，當(dāng)主節(jié)點(diǎn)故障時(shí)，系統(tǒng)能迅速自動完成故障轉(zhuǎn)移，無需人工干預(yù)，極大提升了系統(tǒng)的穩(wěn)定性和可靠性。

Redis 三主三從集群以其卓越的高可用性、容錯(cuò)能力和性能優(yōu)化，成為復(fù)雜應(yīng)用場景下數(shù)據(jù)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(yè)務(wù)對數(shù)據(jù)存儲的高要求，確保數(shù)據(jù)的安全、可靠與高效訪問。

注意將 ip 修改為自己的容器 ip，端口對應(yīng)之前創(chuàng)建的節(jié)點(diǎn) port

?在使用 redis-cli --cluster create命令創(chuàng)建 Redis 集群時(shí)，Redis 會自動根據(jù)提供的節(jié)點(diǎn)數(shù)量和 --cluster-replicas 1的參數(shù)來分配主節(jié)點(diǎn)和從節(jié)
