**Issue:** I can not invoke chromedriver on Linux (debian) machine.
I can see message "Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code."
on Jenkins.
Maven command : clean install test

**My code :**
这是我的硒代码：
if (browserName.equalsIgnoreCase("chrome")) {
System.setProperty("webdriver.chrome.driver", "/usr/bin/chromedriver");
ChromeOptions options = new ChromeOptions();
options.addArguments("--verbose");
options.addArguments("--whitelisted-ips=''");
options.addArguments("--disable-extensions");
options.addArguments("--disable-notifications");
options.addArguments("disable-infobars");
options.addArguments("--incognito");
options.addArguments("--disable-gpu");
options.addArguments("--no-sandbox");
options.addArguments("--disable-gpu --disable-software-rasterizer");
options.addArguments("--disable-gpu-sandbox");
options.addArguments("--disable-features=VizDisplayCompositor");
这些是我到目前为止在chromedriver上尝试过的选项
driver = new ChromeDriver(options); // This line is not being invoked successfully.
------------------------------------------
What I tried so far:
1. I tried firefox browser - which is not launching as well
2. I tried to "chmod 777" files, drivers and folders as per requirement
3. I set up few chrome "options.addArguments" to "disbale GPU" , "headless" and "no sandbox" as per google
4. I looked in VM that if there are already multiple instance opened for Chromedriver via "htop" and other commands to kill the older sessions but I did not see any chrome because it's never been launched

在解决方案之前，我们一直看到以下错误 ：

解决方案后，我没有看到失败/错误，并且我能够在Linux(Debian(上执行：

解决方案步骤和信息：
(1(您可以在包装盒上安装最新的Chrome Linux浏览器
(2(https://chromedriver.chromium.org/downloads 到这里，对ChromeDriver版本进行暴力破解
(3(我正在使用Chrome linux 77(截至2019年9月20日(和Chrome驱动程序76.0.3809.25，为我工作
(4( "请保护 ChromeDriver 和相关测试框架使用的端口，以防止恶意代码访问" - 防火墙一无所获
(5( 检查您的 Chmod 777 Chrome 驱动程序权限
这是一个浏览器和CHROME驱动程序误码，您需要做的就是检查兼容性
