Selenium + Chrome Demo

chrome.py

# coding:utf-8
import time
from selenium import webdriver
from pyvirtualdisplay import Display

display = Display(visible=0, size=(800, 800))
display.start()

driver = webdriver.Chrome()

driver.get('http://www.cnblogs.com/')
time.sleep(5)

title = driver.title
print(title.encode('utf-8'))

# html=driver.page_source
# print(html)

# Release memory
driver.close()
driver.quit()
display.stop()

Something Important

If you run the chrome.py file has error:

Message: unknown error: Chrome failed to start: crashed

And run chromium-browser has following error:

# chromium-browser
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted

Then to use the following method to solved it:

chrome_fix.py

# coding:utf-8
import time
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from pyvirtualdisplay import Display

display = Display(visible=0, size=(800, 800))
display.start()

chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
driver = webdriver.Chrome(chrome_options=chrome_options)

driver.get('http://www.cnblogs.com/')
time.sleep(5)

title = driver.title
print(title.encode('utf-8'))

# html=driver.page_source
# print(html)

# Release memory
driver.close()
driver.quit()
display.stop()
