Linux（CentOS）下配置 Selenium 与 PHP-WebDriver：环境部署及自动化测试实战

# 安装Java环境
yum -y install java-1.8.0-openjdk*x86_64

# 安装Chrome
yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

# 下载selenium（以3.9.1版本为例）
mkdir /usr/local/selenium
wget -c http://selenium-release.storage.googleapis.com/3.9/selenium-server-standalone-3.9.1.jar -O /usr/local/selenium/selenium-server-standalone.jar

# 查看Chrome版本
/opt/google/chrome/chrome -version

# 下载chromedriver（版本需与Chrome对应）
wget -c https://chromedriver.storage.googleapis.com/107.0.5304.62/chromedriver_linux64.zip -O /usr/local/selenium/chromedriver_linux64.zip
unzip /usr/local/selenium/chromedriver_linux64.zip -d /usr/local/selenium/

# 运行selenium服务
java -jar -Dwebdriver.chrome.driver="/usr/local/selenium/chromedriver" /usr/local/selenium/selenium-server-standalone.jar -port 6666
