How can I run Firefox on CentOS 7 minimal with no display?

yum install firefox
yum install xorg-x11-server-Xvfb
Xvfb :1 -screen 0 1024x768x24 &
export DISPLAY=:1

cp geckodriver /usr/bin/

or

Just install PhantomJS. Then, change this line:

driver = webdriver.Firefox()

to:

driver = webdriver.PhantomJS()

The rest of your code won't need to be changed and no browser will open. For debugging purposes, use driver.save_screenshot('screen.png') at different steps of your code or just keep using the Firefox webdriver in development.

crontab

0 1 * * * cd /opt/kdb/kdb_crawler; export DISPLAY=:1; /usr/bin/nohup /opt/python36/bin/scrapy crawl tmall-xpath > /opt/kdb/kdb_crawler/log/date +\%Y-\%m-\%d 2>&1 &
