【问题描述】：
我在连接到 HA 集群中的备用服务器时遇到了一些问题。我只有小学和中学。我正在使用 stomp.py 和 JMS 进行测试。
在我们的云服务器上设置 HA 之前，我正在使用虚拟机和模拟本地网络来试验配置。我可以像这样使用 IP 连接主节点：
stomp -H 192.168.56.105 -P 61616 -U 测试 -W 密码
但是在关闭主服务器后，我无法与辅助服务器连接。我不确定它是否真的激活了。
stomp -H 192.168.56.106 -P 61616 -U 测试 -W 密码
这给出“无法建立连接，因为目标机器主动拒绝它 无法连接到主机 192.168.56.106，端口 61616"
另外，我一直在使用 ha > replicated-failback 示例，我已经多次阅读集群和 HA 的文档，试图弄清楚我缺少什么。
这是我尝试确认 UDP 连接的方式。在我看来，接受者似乎正在出现，但网络上的集群却没有出现。

有什么想法吗？我的配置如下。

【问题讨论】：
-
您是否确认在您停止直播时备份正在激活？您可以通过查看备份日志来做到这一点。
-
我在辅助服务器上检查了 [broker]/log/artemis.log。关闭主节点后，此日志中根本没有任何内容。这是正确的吗？
-
如果在实时中断时没有任何内容打印到备份日志中，那么这意味着 2 个代理没有正确配对。每个代理都在自己的虚拟机中运行吗？如果是这样，你能确认 UDP 在它们之间工作吗？另外，您能否发布包括代理启动过程的实时和备份日志？
-
我重新启动了两台服务器，然后关闭了主服务器。之后，我将那部分日志复制到我的帖子中。我还尝试使用 nmap 确认 UDP 的输出，尽管我不确定我是否正确使用它。看起来接受器出现在网络上，但不是发现和广播组 - 但是广播组和集群出现在控制台中。
-
谢谢贾斯汀。好主意。我什至没有意识到我们可以将其设置为静态。第一次尝试就成功了。
