远程Webdriver上的Chrome（通过Grid）无法启动

Question

我在使用Grid上的远程WebDriver功能（使用Firefox和Chrome使用1个Linux集线器和1个Linux节点）使用Chrome启动Cucumber测试时遇到问题。Firefox测试非常顺利，但Chrome返回以下错误：

unknown error: Chrome failed to start: exited abnormally
(Driver info: chromedriver=2.2,platform=Linux 3.2.0-23-generic-pae x86) (WARNING: The server did not provide any stacktrace information)
java.util.concurrent.ExecutionException: org.openqa.selenium.WebDriverException:    java.lang.reflect.InvocationTargetException

Command duration or timeout: 20.67 seconds
Build info: version: '2.30.0', revision: 'dc1ef9c', time: '2013-02-19 00:15:27'
System info: os.name: 'Linux', os.arch: 'i386', os.version: '3.2.0-23-generic-pae',      java.version: '1.7.0_25'
Driver info: org.openqa.selenium.chrome.ChromeDriver (org.openqa.selenium.WebDriverException) (Selenium::WebDriver::Error::UnknownError)

浏览器初始化为：

$profile = Selenium::WebDriver::Chrome::Profile.new
$profile['download.prompt_for_download'] = false
$profile['download.default_directory'] = downloads_path

capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
    platform: "Linux",
    version: "",
    "chrome.profile" => $profile)

browser = Watir::Browser.new(
    :remote,
    :url => 'http://aut.theurl.net:4444/wd/hub',
    :desired_capabilities => capabilities)

更多信息：

• 我尝试了chromedriver 2.3和2.2版本以及selenium-server-standalone 2.35和2.3版本失败。
• 通过终端，chromedriver成功启动，因此路径似乎没问题。

Chrome似乎在远程节点上启动，但立即失败。我有点主意，所以欢迎任何想法或指导。

提前致谢！

更新：添加了更多控制台日志信息。也许这里有更多信息，但是我看不到任何有价值的信息。

Answer 1

最后，它起作用了！

我改变了两件事：

• 使用其他chromedriver（linux64而非linux32）
• 使用Dwebdriver.chrome.driverswitch 在命令中包含chromedriver路径：

  java -jar ./selenium-server-standalone-2.35.0.jar - Dwebdriver.chrome.driver='/opt/drivers/chromedriver' -role webdriver -hub  http://192.168.1.10:4444/grid/register -port 5566 -browser browserName=chrome,maxInstances=5,platform=LINUX &
