基于Linux的集群管理系统设计与实现

Design and implementation of management system for cluster based on Linux

基于Linux的LVS集群系统缺乏全面的管理系统,影响了其集群规模、运行的稳定性等.设计了一套集群管理系统,包括集群运行状态的监控、集群节点的快速安装与恢复、集群的动态调度、管理界面4部分,并对未来集群功能的升级扩展做出准备.整个系统借鉴了其他成熟系统的设计思想,结合现有的各种开源项目及自由软件自主开发.系统已经在大连理工大学VOD视频点播系统的realserverLVS集群中部分实现,系统的稳定性和可操作性都有明显提高.

LVS, the cluster system based on Linux, lacks the overall management system. This influences the scale and the stability of the cluster. Designing a management system for LVS, it includes monitor and control nodes in the cluster, rapidly installs and resumes the nodes, dynamic configure cluster and interface of management system, and prepares for expanding the management when LVS has been upgraded. The whole system has consulted with the mature design idea. The implementation of the system is based on reworking of some open source projects and free software. Some parts of this management system have already been used in the real server LVS cluster system of DUT Video On Demand System. The cluster system is more stable and the operation is more facile.
