项目摘要

This research paper is report about a tiny e-Learning system in the P.SITE system that was improved by a distributed server system. The portal site for IT Education called the P.SITE system which we developed has a tiny e-Learning system. The P.SITE system is meaning Portal Site for IT Education system that was developed four year ago. This P.SITE system is running by Web application of 'Apache Tomcat' on Java application program. In this way, we made the P.SITE system by open source software application and libraries. This tiny e-Learning system had some problems that are weak point of security and server load unbalance.First, we have restructured the P.SITE system by the center server system and the local server system. And, we separated a tiny e-Learning system from the Web application server on the P.SITE. Next, we have installed only a tiny e-Learning system into the new distributed server system. And, we have allocated distributed server system on local area network at the High school campus. Then, when the client request a connection to tiny e-Learning system, the client can access to a tiny e-Learning system which not use the outside network. In this way, we have resolved about that problem of the security and server load unbalance. At last, we have developed automatic installer software package for the local server system.Because for the high school teacher who doesn't have an IT skill standard, can install the local server system easily to the local area network.

本研究论文是关于 P.SITE 系统中的微型电子学习系统的报告，该系统由分布式服务器系统改进。我们开发的IT教育门户网站P.SITE系统有一个小型的电子学习系统。 P.SITE系统是四年前开发的IT教育系统门户网站。该P.SITE系统由Java应用程序上的“Apache Tomcat”Web应用程序运行。这样，我们通过开源软件应用程序和库制作了P.SITE系统。这个小型电子学习系统存在安全性薄弱、服务器负载不平衡等问题。首先，我们对P.SITE系统进行了重构，分为中心服务器系统和本地服务器系统。而且，我们将一个小型电子学习系统与 P.SITE 上的 Web 应用程序服务器分开。接下来，我们仅在新的分布式服务器系统中安装了一个小型电子学习系统。并且，我们在高中校园的局域网上配置了分布式服务器系统。然后，当客户端请求连接到微型电子学习系统时，客户端可以访问不使用外部网络的微型电子学习系统。这样我们就解决了安全和服务器负载不平衡的问题。最后，我们开发了本地服务器系统的自动安装软件包。因为对于没有IT技能水平的高中教师来说，可以轻松地将本地服务器系统安装到局域网中。
