在无界面的CentOS7上安装Selenium+Chrome,并使用facebook的php-webdriver测试
系统环境
Operating System: CentOS Linux 7 (Core)
Kernel: Linux 3.10.0-693.17.1.el7.x86_64
Architecture: x86-64
安装 chrome
使用下面的命令,在root用户下就可以安装最新的 Google Chrome:
yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
安装 selenium
在 seleniump官网 找到最新的版本,下载selenium-server-standalone-X.XX.X.jar文件
注意:最新的版本3.11,不是3.9(2018年3月)
selenium-server-standalone-3.11.0.jar
selenium服务初始化
将上述selenium放入一个文件夹中,输入如下命令初始化
java -jar selenium-server-standalone-3.11.0.jar
注意,需要 java8 环境,可以参考 CentOS7安装java运行环境jdk
安装 chromerriver
在 chromerriver官网下载最新的ChromeDriver压缩包,解压得到chromedriver.exe文件
chromedriver_linux64.zip 2018-03-20 15:22:39
将下载的文件解压,放在如下位置
/usr/bin/chromedriver
给予执行权限
chmod +x /usr/bin/chromedriver
安装 XVFB
输入如下命令
# yum install Xvfb -y
# yum install xorg-x11-fonts* -y
新建在/usr/bin/ 一个名叫 xvfb-chrom 的文件写入以下内容:
vi /usr/bin/xvfb-chrome
#!/bin/bash
_kill_procs() {
kill -TERM $chrome
wait $chrome
kill -TERM $xvfb
}
# Setup a trap to catch SIGTERM and relay it to child processes
trap _kill_procs SIGTERM
XVFB_WHD=${XVFB_WHD:-1280x720x16}
# Start Xvfb
Xvfb :99 -ac -screen 0 $XVFB_WHD -nolisten tcp &
xvfb=$!
export DISPLAY=:99
chrome --no-sandbox --disable-gpu$@ &
chrome=$!
wait $chrome
wait $xvfb
添加执行权限
chmod +x /usr/bin/xvfb-chrome
查看当前映射关系
ll /usr/bin/ | grep chrom
-rwxr-xr-x 1 root root 7874704 Mar 20 14:55 chromedriver
lrwxrwxrwx 1 root root 31 Mar 20 00:24 google-chrome -> /etc/alternatives/google-chrome
lrwxrwxrwx 1 root root 32 Mar 20 14:30 google-chrome-stable -> /opt/google/chrome/google-chrome
更改Chrome启动的软连接
ln -s /etc/alternatives/google-chrome /usr/bin/chrome
rm -rf /usr/bin/google-chrome
ln -s /usr/bin/xvfb-chrome /usr/bin/google-chrome
查看修改后的映射关系
ll /usr/bin/ | grep chrom
-rwxr-xr-x 1 root root 7874704 Mar 20 14:55 chromedriver
lrwxrwxrwx 1 root root 31 Mar 20 00:24 chrome -> /etc/alternatives/google-chrome
lrwxrwxrwx 1 root root 22 Mar 20 00:11 google-chrome -> /usr/bin/xvfb-chromium
lrwxrwxrwx 1 root root 32 Mar 20 14:30 google-chrome-stable -> /opt/google/chrome/google-chrome
-rwxr-xr-x 1 root root 432 Mar 20 00:09 xvfb-chrome
使用facebook的php-webdriver测试
// An example of using php-webdriver.
// Do not forget to run composer install before and also have Selenium server started and listening on port 4444.
namespace Facebook\WebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
require_once('vendor/autoload.php');
// start Chrome with 5 second timeout
$host = 'http://localhost:4444/wd/hub'; // this is the default
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities, 5000);
// navigate to 'http://www.baidu.com/'
$driver->get('https://www.baidu.com/');
// wait until the page is loaded
// $driver->wait()->until(
// WebDriverExpectedCondition::titleContains('百度')
// );
// print the title of the current page
echo "The title is '" . $driver->getTitle() . "'\n";
// print the URI of the current page
echo "The current URI is '" . $driver->getCurrentURL() . "'\n";
// print the pagesource of the current page
$html_selenium = $driver->getPageSource();
echo $html_selenium;
// close the browser
$driver->quit();
