基于WAS的分布式软件部署的研究与实现 摘要 随着计算机软件产业的飞速发展，软件的复杂度越来越高。然而，软件在帮助企业提高效率的同时，也带来了一定的负担，随着企业规模的扩大，复杂的部署环境的以及多变的部署需求，使得对于软件部署的要求也越来越高。基于WAS的分布式软件部署系统在这种形势下应运而生，旨在为应用程序提供一个灵活的部署方案，帮助部署管理员提高部署效率。 本文首先分析了分布式软件部署存在的问题，阐述了WebSphere Application Server对于分布式软件部署的支持并对几种分布式软件部署方案进行了比较；随后简单介绍了Lotus Connections和Lotus Connections Installation项目以及本人在该项目中完成的工作；最后采用面向对象技术，分析、设计并实现了基于WAS的分布式软件部署系统。该系统具有软件部署，节点通信和节点管理，消息管理和配置信息管理，集群同步等功能，为应用程序的部署提供了一套完整而灵活的解决方案，满足了企业用户的需求，提高了部署效率，并且利用WebSphere Application Server的特性屏蔽了底层环境的差异。同时也减轻了部署人员的工作负担。 关键词：软件部署，WebSphere Application Server，集群，部署管理Abstract With the rapid development of computer software industry, software complexity is increasing. Software helps the companies improve the efficiency, but it also brings in some burden. And with the expansion of the business, the difference of the deployment environment, and the changing requirements, making a good needed for software deployment requirements are also increased. WAS-based distributed software deployment system came into being in this situation, it is designed to provide a flexible deployment options to help improve the efficient of deployment. This article analyzes the problems of distributed software deployment, describes WebSphere Application Server support for distributed software deployment and compares methods of the deployment distributed software, then introduce the Lotus Connections and Lotus Connections Installation project and what I did in that project. Finally, this article analysis, design and implementation of distributed software deployment system based on WAS with the object-oriented technology. The system has software deployment, node communication and management, message management and configuration management, cluster synchronization and so no, which provide flexible solution for the deployment of application and meet the needs of users, shield the differences of the underlying environment. Not only improve the deployment efficiency, but also reduce the workload of the
