1.安装chrome

(1) 添加chrome的repo源

 vi /etc/yum.repos.d/google.repo

[google]name=Google-x86_64baseurl=http://dl.google.com/linux/rpm/stable/x86_64enabled=1gpgcheck=0gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

(2)安装

yum update , 然后yum install google-chrome-stable

注意：google-chrome一定一定不要用root用户去运行

 

2.安装chromedrive

从https://sites.google.com/a/chromium.org/chromedriver/home下载chromedriver

配置在PATH路径或者在脚本中指定路径  

wget -N http://chromedriver.storage.googleapis.com/2.29/chromedriver_linux64.zip unzip chromedriver_linux64.zip

chmod +x chromedriver

sudo mv -f chromedriver /usr/local/share/chromedriver

sudo ln -s /usr/local/share/chromedriver /usr/local/bin/chromedriver

sudo ln -s /usr/local/share/chromedriver /usr/bin/chromedriver

 

3.安装Xvfb

无GUI时，Xvfb为虚拟GUI

yum update

yum install Xvfb

yum -install libXfont

yum install xorg-x11-fonts*

 

4.安装selenium、pyvirtualdisplay

pip install selenium

pip install pyvirtualdisplay

 

5.写个小demo测试下效果

 vim test.py

# -*- coding:utf-8 -*-

from selenium import webdriver
from pyvirtualdisplay import Display
　　

display = Display(visible=0, size=(800,600))
display.start()
driver = webdriver.Chrome("./chromedriver")
driver.get("http://www.baidu.com")
print driver.page_source

driver.quit()
display.stop()

 保存文件，执行命令,即可看到效果

python test.py

 

注意注意注意，root用户会报错 Chrome failed to start: exited abnormally，一定要用其它用户执行
