我在Java(1.8)中使用Selenium和Chromedriver进行一些自动网络爬行：

System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("someurl.com");

我正在尝试迁移到Ubuntu 16.04服务器.在服务器上,我安装了Ubuntu chromedriver版本2.37,chrome版本65.根据chromedriver文档,这些版本是兼容的.我更改了代码,指定了Ubuntu中chromedriver的位置：

System.setProperty("webdriver.chrome.driver", "/usr/lib/local/chromedriver");

在运行我的程序之前,我启动了xvfb：

Xvfb -ac :99 -screen 0 1280x1024x16 &
export DISPLAY=:99

然后执行我的程序：

java -jar myprogram.jar

以下内容将打印到控制台：

解决方法:

这个错误确实让我们知道发生了什么错误：

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally

当您尝试在无头Ubuntu Server上启动Chromedriver和Chrome时,您必须按如下方式传递几个选项：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("--headless")
options.add_argument("--no-sandbox")
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path='/path/to/chromedriver')
driver.get('http://google.com/')
driver.quit()

补充笔记

根据强制性Requirements和#1341,确保以下内容：

> Chromedriver在/usr/local/bin /内
> Chrome浏览器位于/usr/bin/google-chrome中
