Web服务器集群架构的设计与实现

Design and Implementation of Web Server Cluster Architecture

单一Web服务器有着性能瓶颈问题,不能很好地为用户提供可用性与可靠性。本文讲解使用开源技术LVS与HeartBeat技术构建高性能、高可靠性集群的三层架构,包括负载均衡层、真实服务器层与共享存储层。

Because of the performance bottleneck of single Web server, it cannot provide the availability and reliability for users. This paper focuses on the three-layer architecture with high performance constructed with open source technology of LVS and HeartBeat, including load balancing layer, real server layer and the shared storage layer.
