1、安裝chrome
用下面的命令安裝Google Chrome
yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
也可以先下載至本地，然後安裝
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
yum install ./google-chrome-stable_current_x86_64.rpm
安裝必要的庫
yum install mesa-libOSMesa-devel gnu-free-sans-fonts wqy-zenhei-fonts
2、安裝 chromedriver（末尾附chrome和chromedriver的對應版本）
chrome官網
wget https://chromedriver.storage.googleapis.com/2.38/chromedriver_linux64.zip
淘寶源（推薦）
wget http://npm.taobao.org/mirrors/chromedriver/2.41/chromedriver_linux64.zip
將下載的文件解壓，放在如下位置
unzip chromedriver_linux64.zip
mv chromedriver /usr/bin/
給予執行權限
chmod +x /usr/bin/chromedriver
3、運行代碼，查看是否成功（python下）
from selenium import webdriver
driver = webdriver.Chrome()
