连接失败'；t注册此节点：发送注册请求时出错：将SeleniumGrid节点注册到集线器时连接失败

Selenium hub已在Windows桌面上启动并运行，请将Windows VM设置为节点。节点不会注册到集线器

步骤1： 在Windows桌面中输入的命令：

java-jar-selenium-server-standalone-3.14.0.jar-角色中心-端口2222

输出：

`11:11:24.171 INFO [GridLauncherV3.launch] - Selenium build info: version: '3.14.0', revision: 'aacccce0'

检查了localhost上的配置页面，发现它就在那里

步骤2： 在Windows虚拟机的命令行中输入以下内容：

java-jar-selenium-server-standalone-3.14.0.jar-role-node-hubhttp://172.20.111.25:2222/grid/register

输出：

您就快到了。注册Selenium网格节点时，需要删除注册uri末尾的附加正斜杠（即

/

），并且可以使用以下步骤：

• 首先，要在端口2222上启动Selenium Grid Hub，需要发出以下命令：

  java -jar selenium-server-standalone-3.14.0.jar -role hub -port 2222
  

  java -jar selenium-server-standalone-3.14.0.jar -role node -hub http://192.168.1.125:2222/grid/register
  

• 您将发现生成了以下日志：

  16:00:50.750 INFO [GridLauncherV3$2.launch] - Launching Selenium Grid hub on port 2222

• 现在，您可以通过URL访问Selenium网格控制台：

  http://localhost:2222/grid/console
  

• 控制台将类似于：

• 现在，要启动Selenium网格节点，您必须发出以下命令：

  java -jar selenium-server-standalone-3.14.0.jar -role hub -port 2222
  

  java -jar selenium-server-standalone-3.14.0.jar -role node -hub http://192.168.1.125:2222/grid/register

好的，我想我已经修复了这个错误

因此，我从我的桌面启动了集线器：172.17.248.33

然后我尝试将节点从虚拟机173.248.137.73连接回我的桌面172.17.248.33

我事先知道，当我从桌面启动集线器，然后在桌面上运行一个节点时，它就会连接

但是，我的印象是，我可以在我的桌面172.17.248.33中启动集线器，然后让我的VM节点173.248.137.73连接到集线器桌面。我猜这是不可能的硒

一旦我从虚拟机启动了集线器并从同一台机器启动了node命令，它就工作了。

删除/并不能解决错误。当我在没有/的情况下运行它时，我仍然收到一个错误：“从集线器获取参数时出错。节点可能会以错误的超时结束。”“连接到/xxx.xxx.xx失败：无法注册此节点：集线器关闭或没有响应：连接到/xx.xxx失败”@lydi签出答案更新并让我知道状态。@lydi您能用主问题中的所有5部分（生成的命令和日志）更新问题以供进一步分析吗。此外，您可以尝试使用

selenium-server-standalone-3.14.0.jar的主发布jar来代替selenium-server-standalone-3.141.59.jar的次发布jar吗？

？使用主发布jar和次发布jar有什么区别？@lydi Great，您可以将xxx.xx.xx更改为它们的实际值。这没什么坏处。这可能会对我有所帮助。这是实际的IP还是你为了演示而手工制作的？无论如何，

178.90.666.34

看起来不是有效的IP。你能交叉检查一下吗？刚刚更新到实际的IP。@DebanjanB我已经更新了帖子，以反映你从上到下的回答，它仍然无法连接到集线器。
