Wildfly 10.1 中的会话复制
Session Replication in Wildfly 10.1
我正在尝试在我的 Wildfly 10.1 应用程序中使用可分发的 WAR 启用会话复制。
我正在 运行 在托管主机提供商上使用 2 个 RedHat 7.2 实例，可以完全访问 OS 和防火墙。我无权访问为我们的流量提供服务的路由器，但主机已确认已启用多播 UDP。
我将 SeLinux 设置为最小值，端口在 iptables 中打开，多播 IP 已被订阅，我的 wildfly 域模式配置使用带有 full-ha-sockets 的克隆 full-ha 配置文件：
这是域配置文件，除数据源外是普通配置文件：

使用 TCPDump，我可以从我的两台服务器上看到 modcluster 的流量。
我还有 运行 McastReceiverTest（来源：https://github.com/belaban/JGroups/blob/master/tests/other/org/jgroups/tests/McastReceiverTest.java）通过：
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
并查看通过的 UDP 流量。
虽然我没有看到来自 wildfly 的 jgroups 的任何东西。在我的日志中，当我查找订阅的频道时，我看到
"Received new cluster view for channel server: [app-one:server-one|0] (1) [app-one:server-one]"
但我从未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 实例前面都有一个 F5 负载平衡器。
我有一些假设希望澄清：
我需要为 Modcluster 启用 Apache 吗？如果您没有单独的平衡机制，我会假设它不会用于负载平衡。
会话复制是否与 运行 宁 "hot-hot" 方案相同，以便 2 个应用程序可以 运行 并保持会话活动？我的理解是，我应该能够登录到服务器 A 上的应用程序，而服务器 B 也能够保持该会话有效。我们正在努力避免对会话粘性的需求。
这 运行 可以在多服务器环境中使用还是仅适用于同一台本地计算机上的 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 个单独的 physicals/vms 上都没有关系。
谢谢。
我找到了一直困扰我的解决方案。我的配置问题出在我的绑定 IP 中。我为我的 jboss.bind.address 使用 127.0.0.1，因为我的 Wildfly 配置前面有 Apache。我将绑定 IP 更改为 NIC 的 IP（在我的例子中是 10.* 地址）。
如果您 post 编辑了整个 standalone.xml 文件，将会很有帮助。
回答您的问题：
不，您可以使用任何负载平衡器。 Mod 集群非常好，因为 Wildfly 直接与其对话，因此在关闭时可以更快地删除服务器。
是的。通过复制，所有会话数据都存储在 Infinispan 中，然后将其复制到集群中的其他服务器。
集群的主要用例是在不同的服务器上拥有实例。
因为我没有您的完整配置并且对您的托管一无所知这是我对问题所在的最佳猜测以便我检查：
- 您在 AWS 中 运行 - UDP 多播在 AWS 中不起作用。您必须使用其他 ping 方法。
- 您的服务器设置为不接受 UDP 多播广播。检查所有防火墙和网络规则。
- 您的配置存在缺陷。如果你post整个配置我可以看一下。
- 您的 web.xml 文件缺少

使用 TCPDump，我可以从我的两台服务器上看到 modcluster 的流量。
我还有 运行 McastReceiverTest（来源：https://github.com/belaban/JGroups/blob/master/tests/other/org/jgroups/tests/McastReceiverTest.java）通过：
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
并查看通过的 UDP 流量。
虽然我没有看到来自 wildfly 的 jgroups 的任何东西。在我的日志中，当我查找订阅的频道时，我看到
"Received new cluster view for channel server: [app-one:server-one|0] (1) [app-one:server-one]"
但我从未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 实例前面都有一个 F5 负载平衡器。
我有一些假设希望澄清：
我需要为 Modcluster 启用 Apache 吗？如果您没有单独的平衡机制，我会假设它不会用于负载平衡。
会话复制是否与 运行 宁 "hot-hot" 方案相同，以便 2 个应用程序可以 运行 并保持会话活动？我的理解是，我应该能够登录到服务器 A 上的应用程序，而服务器 B 也能够保持该会话有效。我们正在努力避免对会话粘性的需求。
这 运行 可以在多服务器环境中使用还是仅适用于同一台本地计算机上的 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 个单独的 physicals/vms 上都没有关系。
谢谢。
我找到了一直困扰我的解决方案。我的配置问题出在我的绑定 IP 中。我为我的 jboss.bind.address 使用 127.0.0.1，因为我的 Wildfly 配置前面有 Apache。我将绑定 IP 更改为 NIC 的 IP（在我的例子中是 10.* 地址）。
如果您 post 编辑了整个 standalone.xml 文件，将会很有帮助。
回答您的问题：
不，您可以使用任何负载平衡器。 Mod 集群非常好，因为 Wildfly 直接与其对话，因此在关闭时可以更快地删除服务器。
是的。通过复制，所有会话数据都存储在 Infinispan 中，然后将其复制到集群中的其他服务器。
集群的主要用例是在不同的服务器上拥有实例。
因为我没有您的完整配置并且对您的托管一无所知这是我对问题所在的最佳猜测以便我检查：
- 您在 AWS 中 运行 - UDP 多播在 AWS 中不起作用。您必须使用其他 ping 方法。
- 您的服务器设置为不接受 UDP 多播广播。检查所有防火墙和网络规则。
- 您的配置存在缺陷。如果你post整个配置我可以看一下。
- 您的 web.xml 文件缺少
