1、sudo yum install firefox -y

2、安装python3l selenium

sudo yum install python3 python3-pip -ypip3 install selenium

3、下载centos7适配的geckodriver

# 创建一个目录用于存放驱动
mkdir -p ~/webdrivers

# 下载最新版本的 Geckodriver (以 v0.33.0 为例)
cd ~/webdrivers
wget https://github.com/mozilla/geckodriver/releases/download/v0.33.0/geckodriver-v0.33.0-linux64.tar.gz

# 解压文件
tar -xvzf geckodriver-v0.33.0-linux64.tar.gz

# 移动到系统路径
sudo mv geckodriver /usr/local/bin/

# 设置执行权限
sudo chmod +x /usr/local/bin/geckodriver

#!/usr/local/python3/bin/python3
