【摘要】：随着信息技术的发展和网络技术的不断完善，用户处理的数据日益增加，对数据的存储、管理要求不断提高，出现了一种新的数据存储技术—云存储（CloudStorage）技术。云存储因其本身具有的特点：便捷性—用户可以随时随地的访问；灵活性—用户可以按需购买；成本低—不需要自己管理维护，省时省力降低了成本等等特点被人们关注。目前，越来越多的企业想在企业内部提供一种云的服务来满足存储需求。在架构云存储平台时，大量的技术问题需要我们考虑。如底层存储资源及安全性、服务器的管理及高效利用、多平台之间的数据交互及共享、对外服务的一致接口、多种终端的访问等等。同时，随着用户数量的增加，如何保证架构的稳定性、安全性、可用性等等，最重要的还有服务器的安全问题这些都必须采取一定的技术手段才能得到保障。本文所设计的小型云存储管理系统是在对主流的云存储系统进行研究之后，结合工作中遇到的实际问题，而设计的一种适合企业或一定量用户内部使用的系统。主要为用户数据存储和管理带来方便，结合MongoDB数据库实现的一种分布式存储系统，利用MongoDB的弱一致性、开源、访问迅速、支持大容量存储、第三方支持丰富、性能优越等等特性，来管理和存储元数据信息。并且结合上层用户端的Web管理系统的设计，把用户分为普通用户、管理员、超级管理员三个等级：普通用户能够对文件和数据进行一些常规的操作：增加、删除、改写、查找，另外普通用户还有相应的上传、下载的权限；而管理员能对自己组的成员进行管理，，处理他们的申请、查看成员信息、共享组内文件、管理组信息；超级管理员能够实现普通用户和管理员所有的功能，并能对管理员进行管理。这样能更好的访问存储在分布式存储节点上的数据，提高系统效率。作为云储存管理系统有效解决了数据的存储和管理问题。
[Abstract]:With the development of information technology and the improvement of network technology, the data processed by users is increasing day by day, and the requirement of data storage and management is increasing. A new data storage technology, Cloud Storage (Cloud Storage), has emerged.Cloud storage is concerned because of its own characteristics: convenience-users can access anytime and anywhere; flexibility-users can buy on demand; low cost-no need for their own management and maintenance, saving time and effort to reduce costs and so on.At present, more and more enterprises want to provide a cloud service to meet the storage needs.In building cloud storage platform, a large number of technical issues need to be considered.Such as the underlying storage resources and security, server management and efficient use, multi-platform data exchange and sharing, external services of the consistent interface, access to a variety of terminals and so on.At the same time, with the increase in the number of users, how to ensure the stability, security, availability and so on of the architecture, and most importantly, the security of the server which must take certain technical means to be guaranteed.The small cloud storage management system designed in this paper is a kind of system suitable for the internal use of enterprises or a certain number of users after studying the mainstream cloud storage system and combining the practical problems encountered in the work.It mainly brings convenience for user data storage and management, and combines with MongoDB database to realize a distributed storage system. It makes use of the weak consistency of MongoDB, open source, quick access, large capacity storage and rich third party support.Features such as superior performance to manage and store metadata information.Combined with the design of Web management system on the upper user side, the user is divided into three levels: ordinary user, administrator, super administrator: ordinary user can do some routine operations on files and data: add, delete, rewrite, search, search, add, delete, rewrite, search, add, delete, rewrite and search.In addition, ordinary users also have the authority of uploading and downloading, and the administrator can manage the members of their group, process their applications, view the information of members, share the files in the group, and manage the group information.Super-administrators can achieve all the functions of ordinary users and administrators, and can manage the administrators.In this way, the data stored on the distributed storage node can be accessed better and the system efficiency can be improved.As a cloud storage management system, the problem of data storage and management is effectively solved.
