python linux selenium: chrome not reachable

I'm trying to run selenium on Ubuntu 16.10 Server, but I'm getting WebDriverException : Message : chrome not reachable (Driver info: chromedriver 2.9.248304, platform=Linux 4.8.0-22-generic x86_64)

from pyvirtualdisplay import Display
from selenium import webdriver

display = Display(visible=0, size=(800, 600))
display.start()

browser = webdriver.Chrome('usr/bin/chromedriver')
browser.get('http://www.google.com')
print(browser.title)
browser.quit()

display.stop()

Chrome is installed:

google-chrome --version

Google Chrome 57.0.2987.110

Does Chromedriver work on Linux?

ChromeDriver is a standalone server that implements the W3C WebDriver standard. ChromeDriver is available for Chrome on Android and Chrome on Desktop (Mac, Linux, Windows and ChromeOS).

Adding some chrome options helped!

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--no-sandbox')
chrome = webdriver.Chrome('/usr/local/bin/chromedriver', chrome_options=chrome_options)
