远程网络驱动程序无法启动 - 硒网格

问题描述：

我想在远程节点上运行我的硒网格代码，但它总是会抛出异常。远程网络驱动程序无法启动 - 硒网格

毂：

java -jar /home/bu/selenium-server-standalone-3.0.1.jar -role hub

它将侦听192.168.1.106:4444

节点上：

java -Dwebdriver.gecko.driver=geckodriver -jar selenium-server-standalone-3.0.1.jar -role webdriver -hub http://192.168.1.106:4444/grid/register -port 5566 -host 192.168.1.132

它将侦听192.168.1.132:5566

Java代码：

package example; 

import java.net.MalformedURLException; 
import java.net.URL; 

import org.openqa.selenium.Platform; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.remote.DesiredCapabilities; 
import org.openqa.selenium.remote.RemoteWebDriver; 
import org.testng.annotations.Test; 

public class NewTest 
{ 

@Test 
public void runFirefox() throws MalformedURLException 
{ 

// We have to mention browser which we want to use for test execution 
DesiredCapabilities cap=DesiredCapabilities.firefox(); 

// Set the platform where we want to run our test- we can use MAC and Linux and other platforms as well 
cap.setPlatform(Platform.LINUX); 

// Here you can use hub address, hub will take the responsibility to execute the test on respective node 
URL url=new URL("http://192.168.1.132:5566/wd/hub"); 

// Create driver with hub address and capability 
WebDriver driver=new RemoteWebDriver(url, cap); 

// start application 
driver.get("http://www.google.com/"); 

// get the title and print the same 
System.out.println("Blog title is "+driver.getTitle()); 

driver.close(); 

} 

}

我想通它出

我们需要陈GE

从

-Dwebdriver.gecko.driver =/U01 /驱动器/ geckodriver

要

-Dwebdriver.firefox.marionette =“/ U01 /驱动器/ geckodriver“

eg）

java -Dwebdriver.firefox.marionette="/u01/driver/geckodriver" -jar selenium-server-standalone-3.0.1.jar -role webdriver -hub http://192.168.1.106:4444/grid/register -port 5566 -host 192.168.1.132

答 

WebDriver driver = new RemoteWebDriver(new URL("10.10.25.106:5554/wd/hub"), DesiredCapabilities.firefox());

我不能让什么是你的代码和我之间的差异。我也是这样做的，你可以看看这个'import org.openqa.selenium.remote.DesiredCapabilities;'。如果远程驱动程序错误，我如何获得远程节点的日志？ –

您在尝试之前是否评论过您的网址？你会看到你的控制台上的日志/错误，或者选择一个截图（bug明智） –

确定更新了我的帖子，这应该是100％，请在尝试之前评论你的URL行，并让我知道它是怎么回事！ :) –

此命令行到注册表窗口上的一个节点，我解决了这个问题就像你

java -Dwebdriver.chrome.driver="C:\web-driver\chromedriver.exe" -Dwebdriver.firefox.marionette="C:\web-driver\geckodriver.exe" -jar selenium-server-standalone-3.6.0.jar -role node -hub http://192.168.1.114:4444/grid/register -port 5551
