java -jar {path}/selenium-server-standalone-3.8.1.jar -role hub （預設埠4444）

3、啟動節點

啟動本機節點：

java -jar {path}/selenium-server-standalone-3.8.1.jar -role node  -hub http://localhost:4444/grid/register（預設埠5555）

java -jar {path}/selenium-server-standalone-3.8.1.jar  -port 4445 -role node  -hub http://localhost:4444/grid/register(（指定埠）
 

在其他電腦上啟動節點：

java -jar {path}/selenium-server-standalone-3.8.1.jar -port 4452 -role node -hub http://{啟動hub的機器的IP}:4444/grid/register

java -jar {path}/selenium-server-standalone-3.8.1.jar -port 4453 -role node -hub http://{啟動hub的機器的IP}:4444/grid/register

mac電腦檢視本機正在使用的ip可通過在終端輸入【ifconfig | grep “inet ” | grep -v 127.0.0.1】檢視

測試程式碼，執行chrome，Firefox瀏覽器：

from selenium import webdriver
import time
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
list={'http://127.0.0.1:5555/wd/hub':'chrome',
      'http://127.0.0.1:4445/wd/hub':'firefox'}

for host,browser in list.items():
    print(host,browser)
    driver=webdriver.Remote(command_executor=host,
                            desired_capabilities={'platform'
 
:'ANY',
                                                    'browserName':browser,
                                                    'version':'',
                                                    'javascriptEnabled':True})

    driver.get('http://www.baidu.com')
    driver.find_element_by_id('kw').send_keys(browser)
    driver.find_element_by_id('su').click()
    driver.close()

多執行緒啟動瀏覽器例項
