The Research And Realization Of Computer Cluster Technology

The concept of computer cluster is more an more important in recent years, three popular types computer cluster is high availability cluster, high Performance and load balance cluster. Load balance cluster is suit to large application program, load requests can be routed to different nodes according to the load's current workload. using the skill of Server Consolidation, we can consolidate the functions of Web server, Mail server, FTP server, database server, file server and so on.The thesis mainly introduced the theory of Linux Virtual Server and The Linux Virtual Server framework, study virtual server software, analyzing the LVS structure and the work principle, Eight scheduling algorithms. the LVS packs transmit strategy, and Three IP load balancing techniques—Virtual Server via NAT,Virtual Server via IP Tunneling,Virtual Server via Direct Routing. Research the network application and network load, Develop computer cluster system that is suite to the situation of ZhongYuan oil-field.By researching load balancing cluster, we introduce the load computer cluster system for the service of ZhongYuan oil-field's employee to access internet, for enterprise WWW service, for FTP service. By the experiment movement and real implement, increase the correspond speed of ZhongYuan oil-field exterior export act for to. Cluster that Make use of a group of computer system to do agency, will raise the speed and the stability of the system. It can Increase the Reliability and Manageability and speed of the exterior website and interior website in the oil-field efficiently. The exploitation gathers the safe stability that a group of systems carry out the exterior website in the oil-field efficiently.In the meantime, according to the LVS technique, use the suite tools of Sun company, develop an according to the B/S structure of the LVS management and the supervision system. Using the load balancing clusters will provide a safety and high efficiently way to supply network service for the ZhongYuan oil-field, increasing the Availability and Performance and Manageability of network application.
