基于LVS的数据库集群负载均衡性能测试与分析

The performance measure and analysis of load balancing in database cluster based on Linux Virtual Server

Linux虚拟服务器(Linux Virtual Server,LVS)技术是一种广泛应用于企业集群中的负载均衡技术,目前关于LVS的研究主要是基于Web服务器集群负载均衡性能方面。在一些实际应用场景中,LVS可以直接与数据库集群相结合。将LVS与数据库集群结合,提出一种对LVS架构下数据库集群性能进行测试的方案,并利用HP LoadRunner对负载均衡算法的数据库集群进行负载测试实验,通过数据分析比较,得出LVS提供的算法中较适合数据库集群的调度算法。

Linux Virtual Server（LVS） techology is a load balancing technology widely used in enterprises. Most of the current research about LVS is based on performance of Web server. In some practical scenarios, LVS architecture is combined with database cluster directly. This paper proposed a test method for the performance of database cluster under LVS architecture,using HP LoadRunner to test the load balancing algo- rithm,comparing the data and getting the most effective LVS load balance algorithm.
