我正在尝试使用位于 AWS EC2 服务器上但无法成功运行任何测试的 Selenium 网格在 Ubuntu 14.04.3 上运行 headless chrome 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。我能得到的最接近的答案是 chromedriver 和 selenium 服务器版本不同步，这就是我收到此类错误的原因。
谁能推荐可以成功协同工作的最新 chromedriver 和 selenium 服务器版本？或者您能否帮助建议我如何解决以下错误？附言。我对这些东西很陌生，我上次使用 Linux 是在 48 年前。任何帮助都会非常非常感谢。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
这是我运行以将网络驱动程序注册到集线器的命令:
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' &

最佳答案
感谢@makeMonday。你提供给我的链接对我帮助不大，但还是谢谢你。我意识到我的 Linux 环境可能一团糟。我所做的是将我的版本更新到以下版本，以便我的测试能够成功运行。
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)
然后，我在运行测试之前先运行下面。
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
关于java - 使用 chromedriver 2.20 和 selenium server 2.48.2，测试失败并出现错误 "Chrome failed to start: exited abnormally"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33691405/
