计算机集群中负载均衡技术的研究

摘要

High performance clusters are of more and more interest,in a load balancing cluster,the core of task distribution is the load balance.This paper is concerned briefly about the clusters and load balance,then using apache and tomcat built a cluster environment through set load balance and clusters configuration reasonable, and tested it. The experiences and measurement results show that use apache and tomcat built a cluster environment successfully and this cluster system has a cerntain fault-tolerant capability and expandability,it also has some guidance on large-scale cluster environment build.%高性能集群工作方式越来越受到人们的关注,负载均衡是集群系统中任务分配的核心环节。本文首先对计算机集群和负载均衡等技术进行了简要论述,然后通过合理的设置负载均衡和集群配置,利用apache和tomcat搭建集群环境,对集群和负载均衡环境进行了简单的模拟,并对其进行了测试。实验结果表明,利用apache和tomcat成功搭建了集群环境,并且该集群系统具有一定的容错能力和可扩展性,对以后大规模的集群环境搭建具有一定的指导作用。
