Design And Implementation Of High Availability Cluster Management System

With the development of virtualization technology, particularly advances incomputer technology, For the rational management of data centers, virtualizationtechnology is widely applied cluster,The emergence of cluster,Greatly improves theutilization of data center resources,Data center management and reduce maintenancecosts,Improve management efficiency and high availability services,Provided for theuser to uninterrupted service,In this paper,a cluster management system toachieve.Include：Cluster Configuration Manager and Resource Group Manager.Based on the analysis of the system requirements of the whole ClusterManagement System,Design and implementation of cluster configuration manager andresource group manager.One Cluster configuration management system which is tomanage the cluster file（cluster.conf）,Resource group management system is thesupervision,start, stop and migration of the service; According to modularization design,The definition given in the module, Including the interface between modules lib and thedefinition of high-level communication protocol. This article will focus on analysis ofthe cluster configuration management system and resource group management system,to achieve the cluster file management and resource management group,Finally, to builda test environment,Complete the test to Basic use cases.In this process of development and research, Requirements of the product, Mainachieved the basic characteristics of Virtual machine operations and clusterconfiguration management system, To achieve effective management of virtualmachines, For the cluster of High Availability to provide good support, Completedthe optimization of the configuration management system, The basis of the originalfunction achieve the reverse loading of the configuration file, Make smarter withConfiguration File Management.
