针对云环境下虚拟机运行在单节点中易导致单节点故障的问题。提出一种基于云计算的高可用性集群方案，根据虚拟机在云计算环境中的运行情况和云环境在实际工程中的应用，制定出高可用性集群，通过对磁盘的镜像和磁盘的共享实现存储的高可用性，通过集群管理软件对虚拟机资源进行自动化管理，提高虚拟机资源的可用性。通过此高可用性集群，可达到将计划内及计划外宕机时间减少到最少，其次减少恢复一个失败虚拟机的时间，在最短的时间内恢复虚拟机的运行。实验结果表明在该集群环境下，可确保虚拟机提供具有高度可用性的服务。

This study addresses single-node failures with the application of virtual machines un-der a cloud environment. A high-availability cluster solution is proposed based on cloud compu-ting. A high- availability cluster management is achieved in accordance with the operating of virtual machines under cloud computation and the application of cloud environment in engineer-ing. Disk mirroring and sharing is used to ensure the high availability of storage. An automatic management of virtual machine resources is achieved through cluster management software to promote the practicability of virtual machine resources. With this high availability cluster, the program to reduce both the planned and unplanned downtime can be minimized. The recovery time of a virtual machine is also reduced. Experimental results show that, under the cluster en-vironment, the virtual machine can be ensured to provide services with high availability.
