提供关键业务的不间断服务,目前的解决办法是采用双机热备或者集群技术,采用基于开源Linux—HA项目下的免费软件Heartbeat作为双机热备方案无疑是极具性价比的选择。讨论了Heartbeat的基本原理,提出了一种基于Linux的双机热备系统,并基于B/S架构建立了该系统的管理模式。
Providing incessant services for key business, the current solution is the hot standby or cluster techniques. Heartbeat, which is based on open source Linux-HA project, is probably a good hot standby solution in performance and cost. The fundament theory of Heartbeat was discussed, and a Linux based hot standby technique was presented, while a B/S based management model for this system was also built.
