【问题描述】：

我正在尝试连接到我自己的 selenium 网格集线器。我正在为节点使用 Windows 10。用于集线器的 Mac。

我在 Mac 上运行这个命令。

 java -jar selenium-server-standalone-3.141.59.jar -role hub

它正在准备注册节点

07:08:15.219 INFO [Hub.start] - Selenium Grid hub is up and running
07:08:15.219 INFO [Hub.start] - Nodes should register to http://192.168.1.104:4444/grid/register/
07:08:15.220 INFO [Hub.start] - Clients should connect to http://192.168.1.104:4444/wd/hub

然后我尝试使用此命令连接到集线器

java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://192.168.1.104:4444/grid/register/

它永远不会连接到集线器并永远尝试

我的 Mac 仍在运行，但这表示没有响应...

我该如何解决这个问题？

【问题讨论】：

您好，欢迎来到 Stackoverflow！也许您的问题与网络有关；您是否检查过您的 Mac 是否没有阻塞所需的端口？两台电脑在同一个网络？他们可以看到任何其他正在运行的服务吗？
您好，先生！ Mac 没有阻塞端口。但是两台计算机都在同一个网络上。如果他们的计算机在同一个网络上，我应该做些什么吗？

【解决方案1】：

您需要在服务器端口之后启动节点，而不需要任何其他路径。见documentation。

你的命令是：

java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://192.168.1.104:4444

感谢您提供遮阳篷。我尝试了那个稍微改变输出的命令。但仍然无法连接。出现这样的错误 07:11:10.382 WARN [SelfRegisteringRemote.registerToHub] - 从集线器获取参数时出错。节点可能以错误的超时结束。无法连接到 /192.168.1.104:4444 你对此有什么想法吗？
我尝试使用该命令从 Windows 连接 mac，然后就可以了！非常感谢！
