Selenium Grid 节点无法连接到 Hub
Selenium Grid Node cannot connect to Hub
我正在尝试在我的 Mac 上启动一个 Selenium Grid 集线器，然后在我的 Mac 上的 Windows 7 VM 上设置一个节点（运行在 VirtualBox 中安装，如果重要的话）。我正在 运行 在 Mac:
上执行此命令
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
厉害，厉害。然后我进入我的 Windows VM 和 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
最终会超时，无法连接。我在下面粘贴了调试信息。

*edit：我尝试在 windows VM 上 运行 集线器和节点，并且没有任何问题。我还尝试 运行 仅 Mac 上的集线器和节点，但我遇到了同样的问题。这对我来说，这个问题在某种程度上与我的 Mac 有关。不知道该怎么办....
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 IP 地址。出于某种原因，它正在选择 vpn 网关的 IP 地址。添加 -host 10.11.xx.xx 解决了我的问题。
没想到设置selenium grid像1-2-3这么简单
因为我花了几个小时浏览和 运行 不同的命令。我希望我先登陆此页面，可能会节省我的时间。
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：我没有注意步骤2，它已经清楚地说明了URL在哪里注册节点，我一直使用windows10 ip-address，因此节点没有连接到中心
从这里下载了最新稳定版本的 selenium 服务器 jar 文件：https://selenium.dev/downloads/
并将 jar 文件放在我计划使用的两台机器上，一台用于集线器，另一台用于节点
就我而言，我使用 windows10 作为集线器，使用 windows7 VM 作为节点
在 windows10 中执行了以下命令 - 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 已启动并且 运行
