centos7.4 实例
利用 yum 命令安装 google-chrome 超级简单（安装最新版）：
yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
chromedriver 也下载最新版就好，和Mac 版本一样，我依旧选择这个最新版本：
http://chromedriver.storage.googleapis.com/index.html?path=70.0.3538.16/
Python3.7 之前安装过：
然后配置一下，就能跑起来 selenium 项目了，当然该 pip install xxx 安装模块就缺什么安装什么了
# 设置 webdriver 参数 options = webdriver.ChromeOptions() # 设置谷歌浏览器的一些选项 # proxy 代理 options 选项 options.add_argument(r‘--proxy--server=http:\\‘ + ip) uas = get_uas() # 设置user-agent options.add_argument(‘user-agent=‘ + choice(uas)) # 以 headless 方案运行 options.add_argument(‘--headless‘) options.add_argument(‘--no-sandbox‘) # options.add_argument(‘--disable-dev-shm-usage‘) # 禁用图片访问 # prefs = {"profile.managed_default_content_settings.images": 2} # options.add_experimental_option("prefs", prefs)
如果不配置 # 以 headless 方案运行
会抛出下面异常

selenium 代码正确运行：
centos7.4 64位安装 google-chrome 与 chromedriver 运行 Python selenium 项目
