摘　　要：为满足能量管理系统Ⅲ区Web服务高并发访问的需求,文章提出了一种Apache与Tom cat集群整合的解决方案。方案使用Apache软件作为前端请求分发器,后端则以集群方式部署了多个Tom cat实体,Apache均衡地将客户端请求分发给Tom cat集群。对一个实际系统进行压力测试,数据显示系统并发用户数从120个提升到340个左右,证明本方案能使系统的并发性能得到显著提升。同时由于Tom cat以集群方式部署,系统的稳定性和可扩展性也得到了很大的提高。To meet the need of high concurrent access in the Zone III of EMS system, this paper presents a solution on the basis of integrating Apache with Tomcat. The solution uses the Apache as a front-end request dispatcher, and deploys multiple Tomcat instances with the clustering mode in back-end. The requests are evenly distributed to Tomcat clustering by the Apache. The results of load testing of an actual system show that the number of concurrent users increases from 120 to about 340 and the concurrent performance of the system is significantly improved. Moreover, the stability and scalability of the system are also greatly improved using the clustering deployment mode.
