摘要 本文针对网络服务商普遍面临的的高并发访问量导致响应速度迟缓的问题进行分析,研究了基于LVS(Linux虚拟服务器)和KEEPALIVED(交换机制软件)的高可用负载均衡的原理,实现了一个可伸缩的、高可用的并具有容错容灾能力的负载均衡系统,该系统采用VS/DR的模式搭建,系统基于IP层和基于内容请求分发的负载平衡调度解决算法,将这些算法在Linux内核中进行实现,并对系统的高可用和负载均衡进行实验,实验证明,该负载均衡系统能对客户的请求进行分流,能有效减轻单个服务器的负载压力。 This article in view of the high concurrency network service providers generally facing the traffic analysis leads to the problem of slow response speed, the LVS are studied (Linux virtual server) and KEEPALIVED (software which exchange mechanism of the principle) of load balancing, high availability ale implemented a scalable, highly available and disaster tolerance ability of load balancing system, using VS/DR model of the system and the system based on IP layer and load balancing scheduling solution algorithm based on the content request distribution, the algorithm is implemented in the Linux kernel, and the system's high availability and load balancing experiments, experiments show that the load balanc- ing system shunt to the customer request, and can effectively reduce the pressure of the load of a single server.
