我有一个Jenkins主服务器-在Linux ec2实例上配置的从服务器，用于执行自动化测试。通过克隆主实例创建了三个从属实例。具体配置如下： Java版本-1.8.0_191 Chrome版本-70 ChromeDriver版本-2.44
在从属实例上执行测试时，出现以下错误： org.openqa.selenium.WebDriverException：无法访问Chrome
下面是控制台中的错误

在主实例上执行测试时，它可以正常工作。用于初始化驱动程序的代码如下：
public static WebDriver getDriver(){
//Get the current OS Version
String os = System.getProperty("os.name").toLowerCase();
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
//Define the path of Chrome Driver on Test Server
if(os.contains("linux")) {
System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");
}
webdriver = new ChromeDriver(chromeOptions);
webdriver.manage().window().setSize(new Dimension(1920,1080));
return webdriver;
}
我已经尝试给出此question中给出的二进制路径 我尝试升级到此question中提供的最新版本。什么都没有。我还尝试添加以下代码来初始化浏览器。
public static WebDriver getDriver(){
//Get the current OS Version
String os = System.getProperty("os.name").toLowerCase();
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
//Define the path of Chrome Driver on Test Server
if(os.contains("linux")) {
chromeOptions.addArguments("--no-sandbox");
chromeOptions.addArguments("--disable-setuid-sandbox");
chromeOptions.addArguments("start-maximized");
chromeOptions.addArguments("disable-infobars");
chromeOptions.addArguments("--disable-extensions");
System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");
}
webdriver = new ChromeDriver(chromeOptions);
webdriver.manage().window().setSize(new Dimension(1920,1080));
return webdriver;
}
注意-这些测试以前可以在所有实例上正常运行。在所有4个ec2实例上，java版本均从1.8.0_171更新为1.8.0_191，此后便出现了问题。
