How to Use Linux Headless Chrome to Browse and Capture Douyin Content

1. Add a custom YUM repository for Google Chrome

vim /etc/yum.repos.d/google-chrome.repo

2. Repository configuration

name=google-chrome baseurl=http://dl.google.com/linux/chrome/rpm/stable/x86_64 enabled=1 gpgcheck=1 gpgkey=https://dl.google.com/linux/linux_signing_key.pub

3. Install Google Chrome

# yum -y install google-chrome-stable --nogpgcheck

4. Verify the installed version

# google-chrome --version

5. Use headless Chrome from the command line

5.1 Capture a screenshot of a page

# google-chrome --no-sandbox --headless --disable-gpu \
    --screenshot https://www.baidu.com/

This creates screenshot.png in the current directory and prints warnings about the missing user‑data directory and GPU support.

5.2 Capture search results

# google-chrome --no-sandbox --headless --disable-gpu \
    --screenshot "https://www.baidu.com/s?wd=足球宝贝"

5.3 Capture a Douyin live page

# google-chrome --no-sandbox --headless --disable-gpu \
    --screenshot https://www.douyin.com/live/...

5.4 Dump the DOM of a page

# google-chrome-stable --no-sandbox --headless --disable-gpu \
    --dump-dom https://www.baidu.com/

The command outputs the page’s HTML to the terminal.

6. Notes

The --no-sandbox flag is required when Chrome is run as root.

Headless mode disables GPU; warnings about "Passthrough is not supported, GL is swiftshader" are normal.

Use full URLs (including protocol) for all commands.

Output files (e.g., screenshot.png) are written to the current working directory.
