Research And Realization For High Available Cluster Of Load Balance Based On Linux

Along with the explosion of internet, the data flux and the calculation intension grow up continually, all bring the huge challenge to the bandwidth and servers, from the network' s technical development to see, the growth of the network bandwidth is far higher than the growth of the speed in the server and memory, what can to foresee is more and more bottlenecks would appear to in the server. How to build an high available, the high performance/ price, scalability server to meet the increasing requirement of load has become an problem stared in the face. In this circumstance, based on Linux virtual server cluster emerge as the times require.Linux virtual server (LVS), in fact the target is how to establish an high available, high capability, high reliabilities and scalability server cluster based on Linux..And that can meet the increasing demand of internetThis text aim at how LVS build a virtual server on a group of incompact gathered servers, make the whole cluster looked as a virtual server to the user. Another point in this text is how to balance the load of the servers to improve the capability of the whole system. For the sake of improving the performance of the system, by dispatch the load reasonably in the servers, make the load of each server arrive at load share. The main contents include:1. Detailed elaborated the development of a group of server cluster, and it's principal of realization. Still introduced the classification of the cluster in the text, as to it's mainly the applied realm did mostly of introduction. Introduce frame principle of realization .To it's related knowledge for design did the thorough analysis.2. It adopted the technique of virtual server based on Linux in the text, mainly discussed the key technique of cluster which is load balance, lay equal stress on the introduce the balanced technique of IP layer adopt in the text. And on this foundation, adopted the dynamic feedback arithmetic of load balance, achieve the load balance.3. Based on the analysis of server cluster and load balance designing a web server cluster. Through the experiment test, get more satisfied result, and did the...
