Aiming at the problems of concurrent access and system reliability of a large number of users in the geographic information service, geographic information services cluster based on Zookeeper was designed and implemented.Problems were solved including the failure of cluster single point, data consistency, and unified configuration management.The response efficiency and stability of the whole cluster system were improved.From the point of view of implementation, the system structure, design ideas, and workflow of cluster were given, and the interactive relationship between cluster nodes and the realization of global parameter service, group service and naming service were described in detail.The cluster''s concurrent access capability and fault processing ability were verified.%针对地理信息服务遇到的大量用户并发访问和系统可靠性问题,基于Zookeeper,设计并实现地理信息服务集群,解决集群单点故障问题、数据一致性问题、统一配置管理问题,提高整个集群系统的响应效率和稳定性.从实现的角度,给出集群的体系结构、设计思路、工作流程,阐述集群节点间的交互关系和全局参数服务、组服务、命名服务的实现,实验验证了该集群的并发访问能力和故障处理能力.
