摘要
随着数字化校园的建设,高校信息系统快速增加;在多台服务器上安装ESXi并安装虚拟机部署信息系统,构建高可用性群集,提高信息系统的可用性。高可用技术利用心跳信号持续监控物理服务器的工作状态,当服务器出现故障时,快速平稳地迁移受影响的虚拟机,也可以为负载过大的应用程序动态分配资源,有效的实现了高校信息系统的高可用性,确保系统服务正常运行。
With the construction of digital campus, university information system to rapidly increase;install esxi on multiple servers and install virtual machine deployment information system, construction of high availability cluster, improve the availability of information system. High availability technology using the heartbeat signal continuously status of monitoring the physical server. When a server failure, rapid and smooth transfer of the affected virtual machine, can also load the application dynamic allocation of resources, the effective implementation of the high availability of information system in Colleges and universities, to ensure the normal operation of the service system.
