Step 4 :- Install puppeteer in CentOs7
npm install --save puppeteer
1
npm install --save puppeteer
Now Let’s Write a Sample Code to run Puppeteer in headless mode and name that file as test.js

'use strict';
const puppeteer = require('puppeteer');
const fs = require('fs');
(async () => {
  console.info("Starting browser");
  let browser;
  try {
    browser = await puppeteer.launch({});
  } catch (e) {
    console.info("Unable to launch browser mode in sandbox mode. Lauching Chrome without sandbox.");
    browser = await puppeteer.launch({args:['--no-sandbox']});
  }
  console.info("Browser successfully started");
  console.info("Closing browser");
  await browser.close();
  console.info("Done");
})();

'use strict';
const puppeteer = require('puppeteer');
const fs = require('fs');
(async () => {
  console.info("Starting browser");
  let browser;
  try {
    browser = await puppeteer.launch({});
  } catch (e) {
    console.info("Unable to launch browser mode in sandbox mode. Lauching Chrome without sandbox.");
    browser = await puppeteer.launch({args:['--no-sandbox']});
  }
  console.info("Browser successfully started");
  console.info("Closing browser");
  await browser.close();
  console.info("Done");
})();
Step 5 :- Run the Code , you will see the following output

Setup Puppeteer In CentOS 7
running puppeteer centos7 without sandbox mode
Real problem starts here , We are not able to launch browser without --no-sandbox flag.

I Challenge most of you will face this problem while you setup puppeteer in Centos 7. SO Follow down this simple hack to solve this . I struggled a lot , I think you may or may not . But if you have reached this section of article then i firmly believe you have faced this as well.
For running Puppeteer in sandbox mode we need to do few changes as of now .

sudo mv chrome_sandbox chrome-sandbox
sudo chown root chrome-sandbox
sudo chmod 4755 chrome-sandbox

sudo mv chrome_sandbox chrome-sandbox
sudo chown root chrome-sandbox
sudo chmod 4755 chrome-sandbox
So what are we doing here ,

We are renaming the chrome_sandbox folder to chrome-sandbox as standard chromium searches for file with chrome-sandbox. Now run the test file again.

$ node test.js

 
$ node test.js
 
Starting browser
Browser successfully started
Closing browser
Done
