我可以同时在不同的端口上运行selenium服务器吗？
我看到这篇文章关于如何在2个不同的端口上运行selenium web驱动器服务器。
我试过这样做：
java -Dwebdriver.chrome.driver=./chromedrive -jar selenium-server-standalone-2.44.0.jar -port 4445 java -Dwebdriver.chrome.driver=./chromedrive -jar selenium-server-standalone-2.44.0.jar -port 4444 并运行在端口4445上调用服务器的代码
但我得到这个例外：

顺便说一下，服务器能否同时处理来自多个客户端的请求到一个端口？ 或者我是否需要为每个客户提供不同的端口？
是可以在不同端口上运行服务器，服务器可以处理来自同一端口的服务器客户端的请求。 您是否尝试在此设置集线器/节点设置？
毂：
java -jar selenium-server-standalone-2.44.0.jar -role hub -port 4444
节点：
java -jar selenium-server-standalone-2.44.0.jar -role node -hub http://localhost:4444/grid/register -port 5557
看起来你有错字。
我想它应该是
java -jar selenium-server-standalone-2.44.0.jar -Dwebdriver.chrome.driver=./chromedriver -port 4445
你错过了
-Dwebdriver.chrome.driver=./chromedriver
您可能希望通过命令行分解。
