与亚马逊 AWS 上的 Hazelcast 的连接问题
connection issue with hazelcast on amazon AWS
我在两台亚马逊 AWS 虚拟机上使用 Hazelcast v3.6（不使用 Hazelcast 的 AWS 特定设置）。连接应该通过 TCP/IP 连接设置（不是多播）工作。我已经在虚拟机上开通了5701-5801地址连接
我尝试在两台虚拟机上使用 iperf，我可以看到一台 VM 上的客户端连接到另一台 VM 上的服务器（当我切换 iperf 的客户端服务器设置时反之亦然）。
当我在不同的 VM 上启动两个 Hazelcast 服务器时，没有建立连接。下面给出了日志语句和 hazelcast.xml 配置（我没有使用 Hazelcast 的编程设置）。我已更改以下 IP 地址：

注意：
我忘了提到我可以从 hazelcast 客户端连接到服务器，即当我使用 hazelcast 客户端连接到单个 hazlecast 服务器节点时，我能够正常连接
包含 0 的出站端口范围被 hazelcast 解释为 "use ephemeral ports"，因此 <outbound-ports> 元素实际上对您的配置没有影响。 hazelcast 来源中有一个相关的测试：https://github.com/hazelcast/hazelcast/blob/75251c4f01d131a9624fc3d0c4190de5cdf7d93a/hazelcast/src/test/java/com/hazelcast/nio/NodeIOServiceTest.java#L60
