1. New Post
Now you don't need to install Firefox or Chrome in a Linux Server without GUI, you only need to copy the drivers from
- https://github.com/mozilla/geckodriver/releases for Gecko (Firefox) or
- https://chromedriver.chromium.org/downloads for Chrome
And you have to set options to "headless"
Here is the code of a class to use headless chrome and gecko that works in an ubuntu server
package ximodante.basic.utils.selenium;
import java.io.File;
import java.io.IOException;
import java.time.Duration;
import java.util.HashMap;
import java.util.Map;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.By;

import org.openqa.selenium.Point;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.firefox.FirefoxProfile;
//import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.openqa.selenium.support.ui.FluentWait;
import org.openqa.selenium.support.ui.Wait;

2. OLD Post Don't use it!
1. Install xvfb

sudo apt-get install xvfb
#set display number to :5
Xvfb :1 -screen 5 1024x768x8 &
export DISPLAY=:1.5
#you are now having an X display by Xvfb

2. Install chrome
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.debwget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb
Gives an error (because expects the system to have a GUI) . But you must check the version in the log
in my case it is 95.0.4638.47+
3. Download the chromedriver
in
https://chromedriver.chromium.org/downloads
select the desired version in this case 95.0.4638.17
download it in a directory that will be referenced by the java software!!!
4. What else
Now from the java program, the references to the chromedriver should be to the new server, and follow the steps of the last posts.
