摘要： 传统的关系型数据库已无法满足海量数据的存储与访问需求。针对该问题，提出一种非关系型数据库(NoSQL)的分布式存储与扩展解决方法。分析并改进NoSQL，讨论基于一致性哈希算法键值对的分布式存储，以及基于双hash环的数据库服务器节点的扩展方法，提出将NoSQL作为镜像引入数据库架构系统。实际应用结果表明，该方法可以避免资源浪费及服务器过载。

Abstract: The traditional relational database can not meet the storage and access requirements. Aiming at this problem, this paper presents a solution of NoSQL distributed storage and extension. It analyzes and improves the NoSQL, and discusses the solution on NoSQL key/value distributed storage based on consistent hashing algorithm and extension based on double hash ring. NoSQL is led into the current structure as a mirror system. The practical application results show that the solution can avoid the waste of resources and server overload.
