我已经用LVSconfiguration了Keepalived以在四个Nginx Web服务器（RR模式，没有持久连接）之间传播负载。 我打算启用SPDY，但似乎SPDY每个主机build立一个单一的TCP连接，所以当一个Web节点从池中删除时，客户端尝试发送进一步的请求，原来的连接，但负载平衡器不能移动现有的连接到一个新的服务器，所以所有的Web请求超时该客户端。
有没有办法强制负载平衡器closures所有连接到一个失败的服务器或可能是任何其他的解决scheme吗？
尝试打开持久性，然后expire_quiescent_template
123 expire_quiescent_template - BOOLEAN 124 0 - disabled (default) 125 not 0 - enabled 126 127 When set to a non-zero value, the load balancer will expire 128 persistent templates when the destination server is quiescent. 129 This may be useful, when a user makes a destination server 130 quiescent by setting its weight to 0 and it is desired that 131 subsequent otherwise persistent connections are sent to a 132 different destination server. By default new persistent 133 connections are allowed to quiescent destination servers. 134 135 If this feature is enabled, the load balancer will expire the 136 persistence template if it is to be used to schedule a new 137 connection and the destination server is quiescent.
