在keepalived+lvs的配置文件keepalived.conf中有一个选项persistence_timeout 该选项的作用:在一定时间内使来自于同一个Client的所有TCP请求被负载到同一个RealServer上。 查看已设置的persistence_timeout时间: ipvsadm -S -n 查看Client连接到Server端的请求负载情况: ipvsadm-L-n-c#当设置了persistence_timeout 时间...
persistence_timeout 300 单位秒 这个参数的意义是保持客户端的请求在这个时间段内全部发到同一个真实服务器。 正常情况下LVS会保证同一个TCP链接数据包会发往同一个真实服务器。 例如:(192.168.80.1:49165 192.168.80.120:8080 192.168.80.136:8080)LVS会记录这个TCP链接的【原IP与端口,目标IP与端口】,后续的数据...

当一个client访问vip的时候,ipvs或记录一条状态为NONE的信息,expire初始值是persistence_timeout的值,然后根据时钟主键变小,在以下记录存在期间,同一client ip连接上来,都会被分配到同一个后端。 FIN_WAIT的值就是tcp tcpfin udp的超时时间,当NONE的值为0时,如果FIN_WAIT还存在,那么NONE的值会从新变成60秒,再减...
