linux下安装chrome驱动和selenium

前言:

selenium在windows机器上运行,每次会启动界面,运行很不稳定。于是想到用chrome来了的headless无界面模式,确实方便了不少。
为了提高自动化运行的效率和稳定性,于是把selenium自动化环境部署到linux服务器上,这样更方便。

环境::

  • centons 7.6
  • python 3.6
  • chrome 80.0.3978.149
  • chromedriver 80.0.3978.149
  • selenium 3.14

安装chrome

方法1:先下载到本地后安装

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

下载完成后,使用yum安装本地包

yum localinstall google-chrome-stable_current_x86_64.rpm

安装完成后,检查版本号:

[root@xiaoxiao ~]# google-chrome -version
Google Chrome 80.0.3987.149 

chromedriver驱动

下载chromedriver驱动,历史版本http://npm.taobao.org/mirrors/chromedriver找到对应的驱动版本

可以使用wget下载zip包

wget http://npm.taobao.org/mirrors/chromedriver/80.0.3987.106/chromedriver_linux64.zip

解压zip包,如果提示没有zip,那就yum -y install zip先安装

unzip chromedriver_linux64.zip

解压后把chromedriver移动到/usr/bin/目录下

mv chromedriver /usr/bin

查看chromedriver版本号

[root@xiaoxiao ~]# chromedriver --version
ChromeDriver 80.0.3987.106 (f68069574609230cf9b635cd784cfb1bf81bb53a-refs/branch-heads/3987@{#882})

安装selenium

pip3 install selenium
[root@xiaoxiao ~]# pip3 show selenium

测试运行selenium代码

python3 selenium_test.py 
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')  # 无界面
chrome_options.add_argument('--no-sandbox')  # 解决DevToolsActivePort文件不存在报错问题
chrome_options.add_argument('--disable-gpu')   # 禁用GPU硬件加速。如果软件渲染器没有就位,则GPU进程将不会启动。
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--window-size=1920,1080')  # 设置当前窗口的宽度和高度
driver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)
#driver = webdriver.Chrome()
driver.get("https://www.cnblogs.com/june-/")
 
print(driver.page_source)
driver.quit()
如果出现博客title,则运行成功。
