Run Drupal 8 Drush and Cronjob with Crontab

Run crontab in your terminal

root@yoursite:~# crontab -e

This will open a text editor where you can set the cron timings and commands.

Create a new entry like below:

0 1 * * * /var/www/html/drupal8-project/vendor/bin/drush --root /var/www/html/drupal8-project/web/ core-cron -v > /var/log/drupal-8-cron.log

This will run the drush that will call drupal 8 cronjob everyday at 1am and create a log file named "drupal-8-cron.log"
