1.安装Xvfb和pyvirtualdisplay

sudo apt-get install xvfb
pip install pyvirtualdisplay

2.安装chrome, chromedriver和selenium

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo apt install ./google-chrome-stable_current_amd64.deb

wget https://chromedriver.storage.googleapis.com/75.0.3770.90/chromedriver_linux64.zip
解压，将chromedriver加到path中

pip install selenium

到这里。环境就配置好了。接下来就可以上代码了。

from pyvirtualdisplay import Display

from selenium import webdriver

display = Display(visible=0, size=(900, 800))

display.start()

driver = webdriver.Chrome()

driver.get('http://www.umn.edu')

print (driver.title)
