问题
Am using Chrome Headless to run my selenium test script in Unix machine(Cent OS).But the same script works perfectly in my local windows machine.
But in Unix machine it returns empty page source like empty html tags.
Have no clue where its error-ed out though am using latest ChromeDriver 2.33, and google chrome version 62.0..
System.setProperty("webdriver.chrome.driver", "/../chromedriver.exe");
--chromedriver.exe for windows local machine
-- chromedriver for unix machine
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
options.setAcceptInsecureCerts(true);
options.addArguments("--ignore-ssl-errors=true");
options.addArguments("--ssl-protocol=any");
options.setHeadless(true);
driver = new ChromeDriver(options);
System.out.println("Timeout invoke ");
driver.get("https://www.google.co.in/");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
System.out.println("After invoke ");
System.out.println("PAGE SOURCE : \n" + driver.getPageSource());
System.out.println("RUN COMPLETE..");
Running the above in Unix machine i get
PAGE SOURCE:
<html xmlns="http://www.w3.org/1999/xhtml"><head></head><body></body></html>
Help me in fixing this Thanks in advance

To run Chrome Browser in Headless Mode in Unix Systems, add the arguments --disable-gpu and --remote-debugging-port=9222 :
System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
options.setAcceptInsecureCerts(true);
options.addArguments("--ignore-ssl-errors=true");
options.addArguments("--ssl-protocol=any");
options.setHeadless(true);
options.addArguments("--remote-debugging-port=9222");
options.addArguments("window-size=1400,600");
WebDriver driver = new ChromeDriver(options);
System.out.println("Timeout invoke ");
driver.get("https://www.google.co.in/");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
System.out.println("After invoke ");
System.out.println("PAGE SOURCE : \n" + driver.getPageSource());
System.out.println("RUN COMPLETE..");
Note A: Avoid passing both the options addArguments("--headless") and setHeadless(true) together for any single WebDriver instance.
Note B: Avoid using addArguments("--disable-gpu"); on Linux/Unix based systems as it is a configuration for Windows based OS.
Reference : Getting Started with Headless Chrome
Update
As you are seeing :
WebDriverException: chrome not reachable
Follow the steps :
- Uninstall
Chrome BrowserthroughRevo Uninstaller - Run
CCleanertool to wipe off all the OS chores. - Take a
System Restart - Install current version of
Chrome Browser. - Execute your
Test

I had the same issue. Especially when adding the proxy which had no valid certificates. Here's what worked for me: (python code)
polipo_proxy = "127.0.0.1:8124"
proxy = Proxy({
'proxyType': ProxyType.MANUAL,
'httpProxy': polipo_proxy,
'ftpProxy' : polipo_proxy,
'sslProxy' : polipo_proxy,
'noProxy' : ''
})
capabilities = dict(DesiredCapabilities.CHROME)
proxy.add_to_capabilities(capabilities)
capabilities['acceptSslCerts'] = True
capabilities['acceptInsecureCerts'] = True
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--window-size=1280,1000')
chrome_options.add_argument('--allow-insecure-localhost')
chrome_options.add_argument('--allow-running-insecure-content')
chrome_options.add_argument('--no-sandbox')
driver = webdriver.Chrome(executable_path=os.path.abspath("/var/chromedriver/chromedriver"), chrome_options=chrome_options, desired_capabilities=capabilities)

It's problem with ssl certificate , i also had the same issue . for headless chrome following options are not effective , try to reach other non ssl link . chrome options - > --ignore-ssl-errors
回答4:
On Unix you need a reference to the Chrome Binary file too.
options.setChromeBinaryPath("/usr/bin/google-chrome");
