google-chrome - 远程网络驱动程序上的 Chrome(通过网格)无法启动

Question

我在使用 Grid 上的远程 Webdriver 功能(1 个 Linux 集线器和 1 个带有 Firefox 和 Chrome 的 Linux 节点)启动 Chrome 的 Cucumber 测试时遇到问题。 Firefox 测试进行得很顺利，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 版本 2.3 和 2.2 以及 selenium-server-standalone 2.35 和 2.3，但未成功。
• 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。我有点没有想法，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，但我看不到任何有值(value)的东西。

Answer 1

终于成功了!

我改变了两件事:

• 使用不同的 chromedriver(linux64 而不是 linux32)

• 使用 Dwebdriver.chrome.driver 开关在命令中包含 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 &
