Question

我正在尝试在我的Mac上启动Selenium Grid集线器，然后在我的Mac上在Windows 7 VM上设置节点（在VirtualBox中运行，如果这很重要）。我在Mac上运行此命令：

java -jar selenium-server-standalone-3.0.1.jar -role hub

然后我得到

Nodes should register to http://10.10.3.1:4444/grid/register/
Selenium Grid hub is up and running

太棒了，真棒。然后我进入我的Windows VM并运行以下命令：

java -jar selenium-server-standalone-3.0.1.jar -role webdriver -hub http://10.10.3.1:4444/grid/register -port 7777 -debug

它最终会超时，无法连接。我粘贴了下面的调试信息。

*编辑：我试图在Windows VM上运行集线器和节点，并且没有任何问题。我还试图只在Mac上运行集线器和节点，我遇到了同样的问题。这告诉我，这个问题与我的Mac有关。不知道该怎么做....

Answer 1

事实证明，服务器在尝试自动为集线器分配IP地址时，选择了错误的服务器。出于某种原因，它选择了vpn网关的IP地址。添加while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) { echo "status = " . $array['status'] . ' = ' . $array['cnt'] .'<br />'; }解决了我的问题。

Answer 2

我不认为设置硒网格像1-2-3这样简单

因为我花了几个小时浏览并运行不同的命令。我希望我先进入此页面，也许可以节省我的时间。

感谢kroe761。这是相同的解决方案，但是用对我有用的简单步骤编写它们。常见错误：我没有注意Step2，它清楚地指出了要在其中注册该节点的URL，我一直在使用Windows10 ip-address，由于该节点未连接到集线器

从此处下载了硒服务器jar文件的最新稳定版本：https://selenium.dev/downloads/ 并将jar文件放在我计划使用的两台机器中，一台用于集线器，另一台用于节点就我而言，我将Windows10用于集线器，将Windows7 VM用于节点
在Windows10中执行以下命令-命令提示符 java -jar selenium-server-standalone-3.xxx.xx.jar -role hub

15：00：44.044信息[Hub.start]-Selenium Grid Hub已启动并正在运行

15：00：44.045信息[Hub.start]-节点应注册到http://10.0.0.xxx:4444/grid/register/

在Windows7中执行以下命令-命令提示符 java -jar selenium-server-standalone-3.xxx.xx.jar -role webdriver -hub http://10.10.0.xxx:4444/grid/register-端口7777

15：15：51.097信息[SelfRegisteringRemote.registerToHub]-将节点注册到集线器：http://10 .0.0.xxx：4444 / grid / register

15：15：56.394信息[SelfRegisteringRemote.registerToHub]-节点已注册到集线器并读取 y使用

Selenium Grid Node无法连接到Hub
