linux - 在 Linux 上设置 Selenium 节点

Question

我目前正在尝试在 Linux VM( headless )上设置一个 Selenium 节点。集线器正在从端口 5786 上的 Windows 设备运行(4444 正在使用中)。

我使用以下代码启动集线器:

java -jar selenium-server-standalone-
2.53.0.jar -role node –hub http://<myIP>:5786/grid/register -port 5558

当我执行此操作时，它会返回以下错误消息:

Answer 1

在您共享的命令中，即

java -jar selenium-server-standalone-2.53.0.jar -role node –hub http://<myIP>:5786/grid/register -port 5558

您遇到了复制粘贴问题。参数hub 之前的- 好像不是hyphen 字符。

我能够推断出这是一个可能的根本原因，因为 -hub 的值被完全忽略并且正在尝试使用 4444 的默认集线器端口.您共享的堆栈跟踪重复了这一点

13:42:13.435 WARN - error getting the parameters from the hub. The node may end up with wrong timeouts.Connect to 10.146.48.80:4444 [/10.146.48.80] failed: Connection refused

如您所见，即使您提供的 Hub 注册 URL 包含端口号 5786，它仍然会接收到 4444 并提示 Connection refused。

请尝试输入启动集线器的完整命令，然后重试。这应该有效。
