【问题描述】：
我正在尝试为在两个 JBoss 7.2 上运行的 lifey 6.2 设置集群。我的两个应用程序服务器都使用相同的配置，但行为不同。一个正在启动并运行良好，另一个在启动过程中崩溃。跟集群设置有关。
cluster.link.enabled=true
cluster.link.autodetect.address=10.170.121.184:1531
# second points to db server
如前所述，两台服务器都使用此设置。一旦我删除了这些行，第二个服务器也会启动。但这会阻止我使用集群环境。我在我的日志文件中进行了一些研究，发现了几个异常（在服务器启动时的 liferay 部署期间）。
这是来自 liferays 的日志文件。不是很令人兴奋，因为它并没有真正提供有价值的信息。

但这就是有趣的地方。此日志文件摘录自启动期间（同时）的 jboss 日志。

这两行（来自 jboss 的摘录）对我来说很可疑。

我不知道为什么这个liferay会尝试打开到这个IP的连接，我不知道这个地址是在哪里配置的（我自己从来没有这样做过），我不知道这个地址属于哪个系统（不是我网络中的 IP），我不知道为什么我的其他服务器（具有相同配置）没有遇到此类问题。也许这个地址是某种默认或备用地址？
当我首先启动麻烦的服务器或完全单独启动时，此行为不会改变。这个总是遇到给定的问题。
我确实在 portal-ext.properties 中引用了一些额外的 ehcache 设置来使用单播而不是多播，但是这个配置对于两个服务器也是相同的，所以最初的原因必须在其他地方。但也许我可以使用这些额外的 ehcache 设置来调整这个 IP？
我按照 liferays 的一篇博客文章来设置我的环境。到目前为止，我的 ehcache 设置与本文中提到的相同（因为我的第二台服务器没有启动，我无法检查是否需要进行一些更改）。 https://www.liferay.com/de/web/fimez/blog/-/blogs/configuring-a-liferay-cluster-and-make-it-use-unicast-
是否有人对设置 liferay 6.2 集群有一些经验，或者可能对 ehcache/jgroups 设置有所了解，这可能会有所帮助？我真的很感激。
