Selenium Grid 4节点未在集线器中注册

Question

我们尝试将selenium节点从一台机器迁移到多台机器，并将其中一半迁移到云。

目前，硒网格的结构如下所示：

• 该中心位于AWS EC2上
• office中的Mac迷你节点
• office中的Windows节点
• AWS EC2上的2个Linux节点

当我尝试将节点连接到集线器时，节点不会显示在集线器中，并且节点无限向集线器发送注册事件。

集线器4444、4443和4442端口可以直接连接事件和集线器。

当节点发送注册事件时，Hub中会显示以下日志：Node：

我在配置中遗漏了什么？

更新：

当我在调试模式下运行时，我看到节点的连接超时：

13:45:22.386 FINEST [LoggingHandler.channelUnregistered] - [id: 0xef015bd6] UNREGISTERED

Answer 1

当我在--log-level FINEST中运行集线器时，我发现集线器无法通过端口5555连接到节点。

解决方案是打开机器上的端口5555：

• 使用安全组的AWS EC2
• 使用防火墙入站规则的Windows和macOS
