Analyzing traditional high availability cluster,designing a project based on free open-source software heartbeat and DRBD to solve traditional HA-cluster＇s deficiency on cost,using heartbeat to construct high availability cluster,using DRBD to synchronize data between cluster＇s nodes,constructing and testing an FTP HA-cluster based on this design,giving an resolution to brain-split.%文章分析了传统高可用性集群,针对其成本较高的缺点提出了使用免费开源软件heartbeat构造高可用集群、DR BD在集群节点之间同步数据以取代共享磁盘的方案,并设计使用该方案构建高可用FTP集群的实例,通过测试确认该方案的可行性,最后给出集群脑裂的解决方法。
