摘要
文中简要介绍了多种服务器群集负载均衡的实现方法及特点,着重研究了解了基于Linux操作系统的LVS集群技术,以实现高性能、高可用、低成本的虚拟服务器集群。在此基础上,将LVS的HA模块Heartbeat与Ldirectord健康检查技术很好地结合,将此技术应用于企业业务,在代理、邮件、音视频等访问频繁、服务器返回大量数据的应用中,以低成本代价取得了高效、稳定的应用。
This paper describes several implementations and characteristics of server cluster load equilibrium,with focus on the LVS cluster technology based on Linux operating system,which could achieve virtual server cluster of high performance,high availability and low cost. On this basis,the HA module heartbeat of LVS could be perfectly combined with Idirectord health checking technology. The application of this technology to enterprise business could achieve,more efficient and more stable effect with lower cost in the case of huge data exchange in high-frequency server access to proxy,email system,audio data,video data,and so on.
