使用chromedriver 2.20和selenium server 2.48.2，测试失败，“Chrome启动失败:异常退出”

I am trying to run headless chrome tests on Ubuntu 14.04.3 using Selenium grid that sits on AWS EC2 server but cannot successfully run any test. I have been looking around for answers, tried many solutions/suggestions, but still failed. The closest answer I can get is that the chromedriver and selenium server versions were out of sync that's why I am getting this kind of error.

我正在尝试在Ubuntu 14.04.3上运行无头的chrome测试，它使用的是AWS EC2服务器上的Selenium grid，但无法成功运行任何测试。我一直在寻找答案，尝试了许多解决方案/建议，但仍然失败了。我能得到的最接近的答案是，chromedriver和selenium服务器版本不同步，这就是我为什么会出现这种错误的原因。

Can anyone please suggest latest chromedriver and selenium server versions that can work together successfully? Or can you please help suggest on how I can resolve below error? PS. I am quite new to this stuff and it was 48 years ago when I last used Linux. Any help will be much, much, much appreciated. Thank you very much!

有没有人可以建议最新的chromedriver和selenium服务器版本能够成功地合作?或者你能帮忙建议一下我如何解决下面的错误吗?PS，我对这个很陌生，48年前，我最后一次使用Linux。任何帮助都将是非常、非常、非常感谢的。非常感谢!

Ubuntu: 14.04.3
Java: 1.7.0_80
Selenium: selenium-server-standalone-2.48.2.jar
chromedriver: 2.20.353124

This was the command I run to register the webdriver to the hub:

这是我用来将webdriver注册到hub的命令:

root@ip:~# java -jar selenium-server-standalone-2.48.2.jar -Dwebdriver.chrome.driver='/usr/local/bin/chromedriver' -role webdriver -hub http://172.31.40.186:4444/grid/register -port 5555 -browser browserName=chrome,maxInstances=5,platform=LINUX --verbose --log-path='/usr/local/bin/chromedriver.log' &

Thanks @makeMonday. The link you provided me didn't help me that much, but thanks anyway. I realized I may have had my linux environment all messed up. What I did was update my versions to below in order for my test to get running successfully.

谢谢@makeMonday。你提供给我的链接对我没有多大帮助，但还是要谢谢你。我意识到我的linux环境可能一团糟。我所做的是更新我的版本，以便我的测试成功运行。

Versions

版本

ubuntu=14.04
google-chrome=46.0.2490.86
chromedriver=2.20.353124
selenium server=2.47.1 or 2.48.2 (though sometimes, I am still getting a "session deleted because of page crash" error)

Then, I run below before running the test.

然后，在运行测试之前运行如下。

export DISPLAY=:0
Xvfb :0 -ac -screen 0 1024x768x24 &
google-chrome --remote-debugging-port=9222 &
nohup java -jar ./selenium-server-standalone-2.47.1.jar &
java -jar ./selenium-server-standalone-2.47.1.jar -role node -hub http://<IP>:4444/grid/register -port 5555
