How to run cron with drush within Virtualmin Control Panel

Navigate to => system => Scheduled Cron jobs tab and paste the below command in the command input box. Run it as root and schedule the minutes as required.
Move it up the list to give it more priority. Please note replace with the xxx to your environment.

/usr/bin/env PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin COLUMNS=72 /usr/local/bin/drush --root=/home/xxx/public_html --uri= --quiet cron

Your command line PHP installation is too old. Drush requires at [error] least PHP 5.3.0. To suppress this check, set the environment variable DRUSH_NO_MIN_PHP=1(solved)

If you see the above error, you're probably running a php version not compatible with drush.
To remedy this, use the following command. This is on centos, on ubuntu or other linux flavors the path may be different.

First find the folder where the drush include file is located. You use the linux command
$find / -name "folder_you're_looking for"
Output should be something similar to this

find / -name "drush"
