摘　　要：该文针对Linux上开源项目Linux-HA HeartBeat软件无法实现服务切换的问题,设计并实现了一种服务检测功能。该服务检测功能可以帮助该软件实现服务切换功能,使之成为高可用性的、支持服务切换功能的高可用集群软件。This paper analyses the essential principles and the implementation of the Linux-HA HeartBeat and proposes a scheme aimimg at improving the HeartBeat to solve its problem of failing to examine the status of the service process. Thus the HeartBeat is made to be a highusability cluster heart-beat mechanism that can support the resumption mode in the multi-node, multi-service process, and accordingly a scheme with high performance but low price in the Linux platform.

关 键 词：HEARTBEAT 高可用集群 服务检测 SHELL脚本
