摘要
本文采用虚拟机(VMware)技术搭建高可用集群,在系统中安装多个虚拟机,分别作为多个应用服务器的备用机,采用HA软件检测物理服务器的工作状态,当出现故障时,接管服务。该方案有效地实现了医院信息系统高可用性及数据实时备份,保证服务的不间断性,并且充分利用了现有设备,能够显著降低实施成本,在实际应用过程中已取得良好的效果。
Establishes high availability cluster based on VMware, installing virtual machines as backup servers for application servers. When HA software detects fault on physical server status, the service is taken over. The design can implement high availability and real time backup of data in HIS, insuring the service uninterrupted. And the design takes full advantage of legacy, lowers implementation costs and brings a good effect at practice.
