Running selenium webdriver in AWS EC2 linux

Question

I installed selenium on Amazon Linux AMI. I try to use python to activate it. The error show up. I do not know what is supposed to mean. Can chrome webdriver run on that environment.

My code

from selenium import webdriver
driver = webdriver.Chrome("/home/ec2-user/dlfjj/bin/chromedriver")

Error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ec2-user/dlfjj/local/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
self.service.start()

os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home` 

update: There is new error.

Answer 1

The error states ...

'chromedriver' executable may have wrong permissions

... which means that it cannot be executed. It should work if you add the execute bit in the EC2 instance

$ chmod +x /home/ec2-user/dlfjj/bin/chromedriver

Answer 2

You are missing a library needed by chromedriver!

Run the below command with an unzipped chromedriver :

ldd chromedriver 

If there are missing dependencies, then install them using the below command :

yum install GConf2
