Selenium Headless WebDriver 요구사항
Since we don’t have a screen to run Firefox we are going to be using Xvfb to simulate a display and run everything in memory.
 
  
 +
1. Xvfb를 설치하여 메모리에서 화면을 시물레이션
 +
 +
<source lang=python>
 
apt-get install xvfb
 
apt-get install xvfb
Now we are going to install Firefox and few requirements that maybe already installed on your system but here are anyway:

2. 파이어폭스 설치 및 요구사항 설치
 +

<source lang=python>
 
echo -e "\ndeb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main" | tee -a /etc/apt/sources.list > /dev/null

Now we need PyVirtualDisplay which is a python wrapper for Xvfb used for easy working with virtual displays in python.

3. 파이썬 화면가상화 (Xvfb를 이용 손쉽게 하기 위함 )
 +
<source lang=python>
 
pip install pyvirtualdisplay
 
pip install pyvirtualdisplay
Now we are going to install selenium as a final component for our project:
+
</source>

4.셀리니엄 설치
 +
<source lang=python>
 
pip install selenium
 
pip install selenium
Now here is a simple python script to take a screenshot from a website:

5.파이썬 실행 예제 스크립트

#!/usr/bin/env python

from pyvirtualdisplay import Display
from selenium import webdriver

# Set screen resolution to 1366 x 768 like most 15" laptops
display = Display(visible=0, size=(1366, 768))
display.start()

# now Firefox will run in a virtual display.
browser = webdriver.Firefox()

# Sets the width and height of the current window
browser.set_window_size(1366, 768)

# Open the URL
browser.get('http://www.vionblog.com/')

# set timeouts
browser.set_script_timeout(30)
browser.set_page_load_timeout(30) # seconds

# Take screenshot
browser.save_screenshot('vionblog.png')

# quit browser
browser.quit()

# quit Xvfb display
display.stop()

This will create a file vionblog.png with the screenshot of http://www.vionblog.com front page taken with screen resolution of 1366 x 768
