摘要
首先简要介绍了HA(High Availability)的内容和工作原理,然后详细分析了HA的心跳数据格式和心跳流程,给出了一种增强服务器高可用性的设计方法,并在Unix操作系统Solaris上采用C++完成了HA模块开发。
In this article, the principle and theory of HA（ High Availability） are introduced firstly, which is widely used in cluster protection. And then, Heartbeat, which is the core of HA, is introduced. Based on the above theory, the architecture of HA model is designed, including heartbeat module, command line interface, and configuration module.
