My note about setting selenium
First install virtual display
# install virtual display xvfb
$> sudo apt-get install xvfb xserver-xephyr
# install PyVirtualDisplay which is python wrapper for xvfb
$> sudo pip install pyvirtualdisplay
# install selenium python driver
$> sudo pip install selenium
Second install selenium, google chrome and chromedriver on linux
# selenium server
$> curl -O http://selenium.googlecode.com/files/selenium-server-standalone-2.24.1.jar
# selenium chrome driver
$> curl -O http://chromedriver.googlecode.com/files/chromedriver_linux32_21.0.1180.4.zip
$> unzip chromedriver_linux32_21.0.1180.4.zip
# move chromedriver to /usr/bin, so next time you start selenium server, chromedriver will be loaded
$> sudo mv chromedriver /usr/bin
# install chrome on debia
$> sudo apt-get install chromium-browser chromium-browser-110n
Next, start selenium server
$> java -jar /home/<user_name>/selenium-server-standalone-2.24.1.jar 2>&1 > /dev/null &
Now, when write code to run chrome headless
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(800, 600))
display.start()
browser = webdriver.Chrome()
browser.get("http://www.google.com")
print browser.title
browser.quit()
display.stop()
