摘　　要：针对Linux大规模集群环境下没有通用的应用管理软件以及应用管理效率低下的现状,采用SSH协议和无代理技术,提出了一种通用的集群应用无代理分级管理模型。该模型将Linux集群环境下的应用按照运行方式和启动方式进行分类。文中提出了多维度应用状态综合评估方法、资源池模式应用调度算法、多叉树剪枝分层算法、缓存和并行化技术等,通过编程实现了该模型,开发了包含状态监控、故障告警、启动、停止、守护等功能的通用集群应用管理软件。将该软件应用于甘肃省气象大数据云平台中,结果表明,该软件通用性强,一套软件可以管理360多个集群应用;软件管理效率高,一条命令可以完成多个集群应用的维护;软件监控效率高,在5 s之内能够完成140多台服务器系统及应用的监控。In view of the lack of common application management software and low efficiency of application management in Linux large-scale cluster environment,a general agent-free hierarchical management model for cluster applications is proposed by adopting SSH protocol and agent-free technology.The model classifies the applications in Linux cluster environment according to the running mode and startup mode.A comprehensive evaluation method of multi-dimensional application status,resource pool mode application scheduling algorithm,multi-tree pruning and hierarchical algorithm,caching and parallelization technology are proposed.The model is programmed,and the general cluster application management software including state monitoring,fault alarm,start,stop and guard is developed.The software is applied to the meteorological big data cloud platform in Gansu Province,and the results show that the software has strong versatility,and one set of software can manage more than 360 cluster applications.The management efficiency is high,and one command can complete the maintenance of multiple cluster applications.The monitoring efficiency is high,and the monitoring of more than 140 server systems and applications can be completed within 5 s.
