Question

我使用Infinispan在两台服务器之间创建分布式缓存并利用其故障转移功能。

我最初使用infinispan-core-7.0.0.Final.jar提供的预配置JGroups配置文件在两个本地tomcat实例上测试了我的webservice。由于预先配置的xml文件使用了环回IP地址，因此我能够在两个Tomcat实例之间运行分布式缓存。

然后我将Web服务移动到两个单独的服务器上，并且无法让它们加入同一个组。我创建了自己的自定义JGroups tcp配置xml，因为在预先配置的环境中使用环回ip导致了一些问题。

我在设置tcp或udp频道方面没有多少经验，所以我认为问题可能在于我的JGroups配置文件（我将其基于预先配置的文件）。

我最初的想法是问题可能出在TCP和MPing元素中的bind_addr。这两台服务器位于同一网络上，可以互相ping通。任何人对上面的配置文件有任何提示/见解？

如果有帮助我已经在日志文件中发布了以下Infinispan / JGroups创业公司的内容：

Answer 1

有两个可能的问题：IPv4 / IPv6问题和UDP路由。

首先尝试在两台计算机上设置-Djava.net.preferIPv4Stack=true。

如果这样做无效，请检查您的UDP防火墙和路由设置。

如果你在那里找不到任何奇怪的东西，你将不得不在udp和端口43366和tcp 7800上使用tcpdump并查看是否有任何活动 - 每个节点应至少每15秒发送一些多播数据包
