【问题描述】：

从这里下载 selenium-server-4.0.0.jar 后

https://www.selenium.dev/downloads/

我把这个jar文件放在c文件夹中，然后使用 cmd 我尝试使用此命令启动 selenium 网格集线器

java -jar selenium-server-4.0.0.jar hub

我无法运行 selenium 网格集线器，它显示以下内容

C:\>java -jar selenium-server-4.0.0.jar hub

我试着把这个网址放在 chrome 浏览器中

http://192.168.100.8:4444

然后它显示这个

Unable to find /index.html

【问题讨论】：

看起来非常好。网格控制台的 url 现在是 http://192.168.100.8:4444/ui/index.html#/

【解决方案1】：

似乎selenium-server-4.0.0.jar 已损坏或未正确下载。

删除当前的 Selenium Server jar 并从 Downloads 页面下载新副本。

将 HUB 启动为：

C:\Users\Admin\Desktop\My Own Downloads\SeleniumServer>java -jar selenium-server-4.0.0.jar hub

您将看到以下日志消息：

15:07:34.490 INFO [LogManager$RootLogger.log] - Using the system default encoding
15:07:34.490 INFO [OpenTelemetryTracer.createTracer] - Using OpenTelemetry for tracing

现在您可以通过任一 url 访问 Selenium Grid 控制台：

http://localhost:4444
http://192.168.225.29:4444

【解决方案2】：

我有类似的问题。原来这是一个java问题。我有一些旧的 jdk8 版本。切换到jdk11后就可以正常使用了。
