摘　　要：针对单服务器策略存在单点故障进而导致网络服务质量下降的问题,在分析集群以及负载均衡工作原理的基础上,设计了一种基于LVS+Keepalived结构的Web集群负载均衡系统。调度器采用网络地址转换负载均衡模式及简单轮询调度算法,根据角色权值及活动链接数均衡分配用户负载请求,通过检测网卡状态及主/从调度器角色切换确保系统的高可用性。仿真结果表明,该系统能够有效均衡客户端负载请求,解决了单服务器策略存在的单点故障问题,提升了Web集群系统的综合性能。Aiming at the problem of single point of failure caused by single server policy,which leads to the degradation of network service quality,a web cluster load balancing system based on the LVS+Keepalived structure has been designed based on the analysis of the working principle of the cluster and load balancing.The scheduler uses a network address translation load balancing mode and a simple round-robin scheduling algorithm.It balances user load requests based on role weights and the number of active links,and ensures high system availability by detecting the status of the network card and switching roles of the master and slave schedulers.Simulation results show that the system can effectively balance client load requests,solve the problems of the single server strategy,and improve the overall performance of the Web cluster system.
