Linux高可用性集群的研究与实现

Research and Implementation of High-Availability Cluster for Linux

介绍高可用性集群的概念、组成和基本原理,分析高可用性集群的关键技术。基于开源的Linux-HA,在Linux平台设计实现一个高可用集群系统。测试结果表明,该集群系统可以有效增强服务的可用性,具有高性价比、高可靠性、扩充性能好等特点。

Introduces the basic concepts, composition and principles of high-availability cluster, and analyses the key technologies of HA cluster. Based on open-source Linux-HA, designs a HA clus- ter and realizes in Linux. The test result proves that the system can effectively increase the high-availability of network services, and it has the characteristics of high performance price ratio, high reliability and good expansion performance.
