摘　　要：数据库同城高可靠集群指将多个数据库节点分散部署至不同的数据中心,其中不同数据中心之间的光纤通道长度在25~50km以内,并利用专业工具和技术将多个数据中心的数据库节点整合为一个逻辑数据库集群,从而为前端提供持续、稳定的数据库服务,只要集群内有一个节点能正常运行,数据库服务就不会中断。作为企业“本地高可靠、同城双活与异地容灾”平台的基石,数据库同城高可靠集群是提升业务系统的连续性及保障能力的关键。为了降低企业的学习成本和探索成本,同时提高其集群建设速度和质量,进而辅助其实现科学决策与精准选型,文章拟对传统企业的数据库同城高可靠集群的建设思路进行深入研究,从而提出相应的建设准则供企业借鉴参考,并帮助项目组快速推进数据库同城高可靠集群的建设进程。Database intra-city high reliable cluster refers to the dispersed deployment of multiple database nodes to different data centers,with fiber optic channels between different data centers ranging from 20 to 50 kilometers in length.Professional tools and technologies are used to integrate the database nodes of multiple data centers into a logical database cluster,providing continuous and stable database services for the front-end,as long as one node in the cluster can operate normally,The database service will not be interrupted.As the cornerstone of the enterprise's"local high reliability,local dual activity,and remote disaster recovery"platform,the database intra-city high reliable cluster is the key to improving the continuity and guarantee ability of business systems.In order to reduce the learning and exploration costs of enterprises,improve the speed and quality of cluster construction,and assist them in achieving scientific decision-making and precise selection,the article intends to conduct in-depth research on the construction ideas of traditional enterprise database intra-city high reliable cluster,and propose corresponding construction guidelines for enterprises,and help the project team quickly promote the construction process of database intra-city high reliable cluster.
