Запуск сервера Selenium с помощью sudo
У меня есть скрипт bash (назовем его selenium_server.sh), который запускает автономный сервер Selenium.
#!/bin/bash
java -Dwebdriver.chrome.driver=/usr/lib/chromium-browser/chromedriver -jar /home/username/selenium-server-standalone-3.6.0.jar -debug
Это работает просто отлично, но если я бегу sudo -u username ./selenium_server.sh, похоже, что он работает, но локальный веб-драйвер не может связаться с ним.
Чтобы быть понятным, пользователь username способен запускать сервер самостоятельно, но не через sudo,
Ниже вывод:

Поскольку это связано с сервером, я оставил код драйвера до конца. Вот MWE.
#!/usr/bin/env python3
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(
command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities=DesiredCapabilities.CHROME)
driver.get('https://stackru.com')
driver.close()
