【摘要】 随着校园网络环境的不断改善和图书馆网络技术的飞速发展，各高校图书馆都建立了自己的网站。图书馆网站是图书馆与用户之间交流的桥梁，是开展网上信息服务的最佳方式。本文从图书馆网站建设入手，深入分析研究了图书馆网站建设的若干技术问题。 文章首先介绍了从传统图书馆向数字图书馆的转变过程中图书馆功能的变迁和国内外图书馆信息化的现状，分析了图书馆网站建设存在的问题。接着从服务器配置技术、资源组织与存储技术、负载均衡技术和网络安全技术几个方面予以论述。 服务器是建立WEB站点的基础，服务器配置技术分析了图书馆类网站对服务器的性能要求及服务器选型原则，论述了服务器硬件的选择和服务器操作系统以及软件的配置。 资源存储技术论述了资源存储的三种主要方式DAS、NAS以及SAN，并根据数字图书馆的特点，提出将NAS与SAN相结合，为图书馆提供更佳的信息服务。资源组织技术主要论述了MARC数据、Z39.50标准、DC元数据以及XML在图书馆中的应用。 负载均衡首先分析了用户访问图书馆网站的行为，接着论述了DNS负载均衡、反向代理负载均衡和服务器群集系统，最后给出了图书馆网站负载均衡的典型案例。 网络安全技术分析了图书馆网站安全的重要性，论述了操作系统安全防护、网络安全防护以及数据安全防护。数据安全防护主要论述了数据备份及备份策略的制定。在此安全技术的基础上，提出了图书馆类网站安全防护的一般模型及其安全策略。更多还原

【Abstract】 Along with the campus network environment progressive improvement and the library network technology rapid development, various universities libraries have all established their own websites. Website is a bridge between user and library, and it provides a better way to serve user via web. Beginning with the construction of website, this article analyses some technology problems from the research perspective.This article first describes the transformation of library’s function in the process of digitization and the domestic and foreign libraries information present situation, analyses the problems existing in the construction of library website. Then, the author discusses them from four aspects: the configuration of server, information organization and resource storage, load balance, and network security.The server is the foundation of establishing the website. In the "configuration of server" section, it analyzes the server performance requirement and the server shaping principle of the library website and discusses the selection of hardware and the configuration of operation system and software.In the "resource storage" section, it focuses on three main storage methods: DAS, NAS and SAN. Based on the characteristics of digital library, the author proposes that to achieve better information service, library should combine NAS with SAN. The resources organization technology mainly states the MARC data, the Z39.50 standard, the DC number and XML in library application.In the "load balance" section, it first analyzes the behavior of the users to visit the library website, then states the DNS load balancing, the reverse proxy load balancing and the server pack system, finally produces the typical case of the library website load balance.In the "network security" section, it analyses the importance of the library website security and states the safety of operation system, the network security protection as well as the data security protection. The data security protectionmainly elaborates the data backup and the backup strategy formulation. In this security technology foundation, it proposes the general model of the library website safe protection and the security policy.更多还原
