tomcat - 集群 session 未复制到组节点

Question

我有两个 tomcat 节点，两台服务器都已启动。

当我关闭一台服务器时，出现以下异常并且 session 未被复制。我必须重新登录，我是否错过了一些步骤？

   WARNING: IOException in replication worker, unable to drain channel. Probable cause: Keep alive socket closed[An existing connection was forcibly closed by the remote host].

这只是警告，配置没有错。当您关闭一个 tomcat 实例时，会出现此警告。

大多数情况下您没有将应用程序标记为可分发。

添加<distributable />给定应用程序的 web.xml 中的标记。
