Preface

I need to deploy the selenium crawler program to the Linux server for work. I would like to share this with you. If you are interested, you can take a look.

1. What is selenium?

Selenium is a tool used for web application testing. Selenium tests run directly in the browser, just like real users are operating, and crawlers use it to crawl some data dynamically loaded by js

2. Usage steps

1. Import library

The code is as follows

from selenium.webdriver import Chrome
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options # Use a headless browser from selenium.webdriver import ChromeOptions
chrome_options = Options()
options = ChromeOptions()
options.add_experimental_option('excludeSwitches', ['enable-automation']) # => Remove the browser being controlled by the automated testing software options.add_experimental_option('useAutomationExtension', False)
chrome_options.add_argument("--headless") # => Configure headless mode for Chrome chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')

2. Test code

The code is as follows:

s = Service(r"/home/driver/chromedriver")
driver = Chrome(
     service=s, options=chrome_options
 )
 driver.get("https://www.baidu.com")
 print(diiver.title)

3. Deployment Procedure

1. Install Chrome

The command is as follows:

yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Check the version of Chrome: google-chrome --version

2. Install chromedriver

The command is as follows:

Download the chromedriver driver address according to the corresponding chrome version: https://npm.taobao.org/mirrors/chromedriver
My version number is: 96.0.4664.45
wget https://npm.taobao.org/mirrors/chromedriver/96.0.4664.45/chromedriver_linux64.zip 
yum install -y unzip zip
unzip chromedriver_linux64.zip # Unzip the zip file mkdir driver #Create a new folder to store the driver chmod 777 driver/chromedriver # This is the permission. I give it 777 here

3. Run the test code

Create a new test.py file

vi test.py

Save test.py and run it.
