我正在尝试使用可分发的WAR在我的Wildfly 10.1应用程序中启用会话复制。
我在托管主机提供商上运行2个RedHat 7.2实例，可以完全访问操作系统和防火墙。我无法访问我们的流量所服务的路由器，但主机已确认已启用多播UDP。
我将SeLinux设置为最小，端口在iptables中打开，多播IP已订阅，我的wildfly域模式配置使用克隆的全ha配置文件和全ha-socket：
这是域配置文件，除了数据源之外是vanilla：

使用TCPDump，我可以从两台服务器上看到modcluster的流量。
我还通过以下方式运行McastReceiverTest（src：https://github.com/belaban/JGroups/blob/master/tests/other/org/jgroups/tests/McastReceiverTest.java）：
java org.jgroups.tests.McastReceiverTest -mcast_addr 230.0.0.4 -port 45700
并使用了以下命令：
printf "GET / HTTP/1.0\r\n\r\n" | nc -vu 230.0.0.4 45700
并查看UDP流量。
我没有看到来自wildfly的jgroups的任何内容。在我的日志中，当我查找订阅的频道时，我看到了
＆＃34;收到频道服务器的新群集视图：[app-one：server-one | 0]（1）[app-one：server-one]＆＃34;
但我从来没有在任何一个实例上看到我的第二台服务器。当我测试时，我在两个RedHat实例前都有一个F5负载均衡器。
我有一些我希望澄清的假设：
我是否需要为Modcluster启用Apache？如果您没有单独的平衡机制，我不会认为它似乎用于负载平衡。
会话复制是否与运行＆＃34; hot-hot＆＃34;相同？场景，以便2个应用程序可以运行并保持会话活着？我的理解是我应该能够登录服务器A上的应用程序，服务器B也能够保持该会话的活动状态。我们正在努力防止对会话粘性的需求。
这可以在多服务器环境中运行，还是仅在同一本地计算机上运行2个实例？我认为无论是在本地计算机上还是在同一防火墙后面的2个独立物理/虚拟机上都无关紧要。
谢谢。
我找到了一个一直在逃避我的解决方案。我的配置问题出在我的绑定IP中。我使用127.0.0.1作为我的jboss.bind.address，因为我在Wildfly配置前面有Apache。我将绑定IP更改为NIC的IP（在我的例子中，它是10. *地址）。
答案 0 :(得分：2)
如果您发布了整个standalone.xml文件，那将会很有帮助。
回答你的问题：
不，您可以使用任何负载均衡器。 Mod群集很不错，因为Wildfly直接与它对话，因此在关闭时可以更快地删除服务器。
是肯定的。通过复制，所有会话数据都存储在Infinispan中，然后将其复制到群集中的其他服务器。
群集的主要用例是在不同的服务器上安装实例。
因为我没有完整的配置而且对您的托管事情一无所知这是我对错误的最好猜测，我会检查：
