This article is the Amazon Linux 2 version of Building a Selenium Environment on Amazon Linux in the Shortest Time. If you want to build a Selenium environment on Amazon Linux, please refer to the above link.

Overview

With the end of security updates for Amazon Linux on June 30, 2020, You can now build a Selenium environment on Amazon Linux 2. The procedure is almost the same, but there are some changes. The following is all done as root.

procedure

・ Install ** Google Chrome ** -Installation of ** GConf2 ** * Changed -Install ** ChromeDriver ** ・ Install ** Google Noto Fonts ** -Installation of ** Selenium ** * Changed

Install Google Chrome

If you do it with yum install google-chrome-stable, you will die from the dependency. Let's do the following:

curl https://intoli.com/install-google-chrome.sh | bash

The latest Google Chrome should work fine.

Install GConf2

In the case of Amazon Linux, I could not install it without adding the repository, It's easy to install on Amazon Linux 2.

yum -y install GConf2

Install Chrome Driver

Since the currently installed Google Chrome is 79.0.3945.88, get the corresponding 79.0.3945.36. You can check the version of Google Chrome with google-chrome-stable -version.

Check the Google Chrome version and the corresponding Chrome Driver version here

wget https://chromedriver.storage.googleapis.com/79.0.3945.36/chromedriver_linux64.zip
unzip chromedriver_linux64.zip
mv chromedriver /usr/local/bin/

Install Google Noto Fonts

At this rate, when I took a screenshot of the screen with Selenium Since Japanese characters are garbled, install the font. https://www.google.com/get/noto/

cd ~/Downloads   #Somewhere suitable
wget https://noto-website-2.storage.googleapis.com/pkgs/Noto-hinted.zip
unzip Noto-hinted.zip
mkdir -p /usr/share/fonts/opentype/noto
cp *otf *ttf /usr/share/fonts/opentype/noto
fc-cache -f -v # optional

Install Selenium

This is where Amazon Linux 2 became a hassle. In Amazon Linux2, pip is not included by default, so let's install pip first. The default python version of Amazon Linux 2 is 2.7.16, so I really want to upgrade to 3 series before installing pip, Since there was a concern that yum would not work, I installed it as it is.

If you know how to safely upgrade to python3, including around yum, please teach me ...

yum install -y python-pip

After that, you can install selenium.

pip install selenium

That's all there is to install.

Let's use Selenium

Create a simple test code to take a screenshot of the google top page Let's run it.

`test.py`


from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-gpu')
options.add_argument('--window-size=1280,1024')
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://www.google.co.jp/')
driver.save_screenshot('test.png')

Test.png is created in the execution directory.

By the way, it is an argument added to options, ・ --Headless mode (It will not work unless it is executed with this) ・ --No-sandbox is required for google-chrome-stable to work (You can see it by running google-chrome-stable) ・ --Disable-gpu seems to stabilize the drawing area (The png file created when I ran it without this was black) ---Window-size is the same as specifying the window size It will be.

Finally

The created test.png was as follows. The characters are not garbled. I thought there would be a big change in the migration to Amazon Linux 2, but it seems that it will not affect that much.
