摘　　要：提出一种基于改进的Linux集群系统负载均衡算法.首先通过修改负载权值计算指标,然后通过动态反馈机制收集各个各服务器的实时负载,负载均衡器根据收集的负载信息动态调整服务器权值,最后根据权值选择最优服务器去处理新的任务.仿真测试结果表明,改进负载均衡算法提高了整个系统的响应能力和吞吐量,较大幅度地提高系统的综合性能.In view of the current load balancing algorithm shortcomings,an improved Linux cluster system load balancing algorithm is proposed based on load balancing mechanism.Firstly,the load weight indexes are modified,and the real time server load is collected by the dynamic feedback mechanism,the weights are dynamically adjusted according to the load information of servers collected by the load balancer,finally the optimal server is selected according to the weights to handle the task.The simulation test results show that the improved load balancing algorithm has improved the overall system response capacity and throughput,if greatly improves the comprehensive performance of the system.
