Piranha/Pulse，lvs.cf 具有持久性和服务器故障

我们有以下设置：

  • 红帽 6
  • 两个 Web 服务器之间的 LVS 设置失败
  • 连接持久性为 900 秒

这是一个非常简单的设置，但是当服务器被标记为故障时，piranha/pulse/nanny 进程会将表中该服务器的权重标记为 0，并且不会删除故障服务器。这意味着任何持久连接仍与故障服务器相连，并且负载平衡被破坏。

我们如何告诉保姆强制关闭故障节点，以便与工作节点的持久连接失败？

谢谢

我们有以下 lvs.cf：

尝试echo 1 > /proc/sys/net/ipv4/vs/expire_quiescent_template

答案2

您必须在导演发生故障/恢复时触发一个脚本来删除/添加该导演。

我使用lvs-kiss它，它有一个包含这些情况的脚本的语法。
