Question

我在以独立模式运行的不同VM上有多个Jboss节点。我正在使用分布式Infinispan缓存。下面是我当前正在使用的代码。

JChannel jchannel = new JChannel();
jchannel.setDiscardOwnMessages(false);
jchannel.setName("losci_qa");
JGroupsTransport transport = new JGroupsTransport(jchannel);

manager = new DefaultCacheManager(GlobalConfigurationBuilder.defaultClusteredBuilder()
          .transport().transport(transport).nodeName(cacheClusterName+"-node").clusterName(cacheClusterName)
          .build());

ConfigurationBuilder c = new ConfigurationBuilder();
c.clustering().cacheMode(CacheMode.DIST_SYNC).hash().numOwners(numOwners).numSegments(numSegments).capacityFactor(capacityFactor).build();
c.invocationBatching().enable();
c.transaction().transactionMode(TransactionMode.TRANSACTIONAL).lockingMode(LockingMode.PESSIMISTIC);
manager.defineConfiguration(DIST, c.build());

以上代码在单个节点上成功运行。问题是，当我想与两个节点通信此缓存时，它不起作用。当我在上面的代码中运行时，其打印在日志下方。

通过Infinispan缓存

没有发现成员。

网络域相同，群集名称相同。我在这里做错了什么？如何建立两个节点的集群？我该如何与每个节点通信？

TIA

第一个问题可能是防火墙。禁用两个节点上的防火墙并在没有它们的情况下进行测试（您应在修复规则后重新启动它们）。

使用无参数JChannel构造函数，您默认为udp.xml； PING协议默认在228.8.8.8:45588上组播问候消息。检查多播是否在您的计算机上正确路由（例如，使用netcat / nc）。

如果这样做没有帮助，请启用TRACE日志记录以获取更多见解。
