Jmeter Chromedriver错误：未知错误：从远程主机执行时，DevToolsActivePort文件不存在

Question

我正在尝试使用WebDriver插件和安装的chrome-driver从JMeter执行WebDriver采样器脚本。 JMeter配置为在分布式模式下工作。我目前有2个节点，一个Master和一个Slave。我的脚本驻留在主机上，我正在尝试使用以下命令从主机执行它。

$JMETER_HOME/bin/jmeter -n -t recorder1.jmx -r

我收到此错误：

JMeter-Server在Slave实例上的ubuntu用户下运行。我也使用ubuntu用户从Master机器执行测试。我看到如果chromedriver是用超级用户执行的，它可能会导致像我一样的问题，但事实并非如此。

最奇怪的是，如果我在无头模式下执行相同的脚本，它可以正常工作。此外，如果我从GUI或从机上的命令行执行相同的脚本，它也可以正常工作而不会出错。

安装：

使用Ubuntu 18.04的EC2实例
Apache的JMeter的-5.1
ChromeDriver 2.45.615355
JMeter的-插件-的webdriver-3.0.jar

有任何想法吗？

我也看到了可能的解决方案：org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser

建议在那里添加以下代码：

System.setProperty("webdriver.chrome.driver","pathto\chromedriver.exe");    
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);

但是如何在JMeter的Chrome Driver Config步骤中初始化之前更改chromedriver选项？
