我在作为集线器的机器上运行以下命令（IP 地址：192.168.55.209，操作系统：Ubuntu）：

java -jar selenium-server-standalone-2.25.0.jar \ -role hub -port 4444

然后我在另一台机器上作为节点运行下面的另一个命令（操作系统：Windows 7 64bit）：

java -jar "selenium-server-standalone-2.25.0.jar" \ -role node -port 5555 -hub http://192.168.55.209:4444/grid/register \browser browserName=firefox,platform=WINDOWS

但我在下面收到错误消息：请帮助找出问题所在。（我已禁用防火墙）

我知道这个问题已经存在几个月了，但是我遇到了同样的问题，并且能够通过在 AWS 的防火墙设置中为集线器打开该端口来解决它。

您只需要启动集线器。输入命令行“java -jar selenium-server-standalone-2.14.0.jar -role hub”，然后打开另一个终端并输入命令“java -jar”selenium-server-standalone-2.25.0.jar“ \ -role 节点 -port 5555 -hub http://192.168.55.209:4444/grid/register \browser browserName=firefox,platform=WINDOW"
