In Linux or Unix, Cron is installed as daemon which denotes that it stays dormant for a certain period. Most of the time, this daemon is installed by design as part of the operating system’s distribution.

  • The most basic method is to enter this command:

       # service crond status

  • The probable output will likely be:

       crond (pid ####) is running…

  • In case you don’t secure a confirmation that crond is finally running, restart the app manually. The command will not simply restart crond but configure it to run during start-up as well.

       # chkconfig crond on

  • Once crond is on, you can put functional scripts in all its sub-directories found in /etc and known as /etc/cron.hourly; etc/cron/daily; etc/cron/weekly; and, etc/cron/monthly.  Each directory will run its scripts on the aforementioned periods. Just insert how you want its use and you are ready to go.

Apply Cron in cPanel

The cPanel technique can prove to be easy if you know how to operate cron through the command line.

Step 1: You can see the “Cron Jobs” icon at the cPanel’s main screen below the Advanced header and choose it.

Step 2: At the next page, you can view the header entitled, “Add New Cron Job” with options for Common Settings as well as minutes, hour, or days (intervals) cited previously

Step 3: Choose the appropriate time interval.

Step 4: Enter the command/commands that you want the system to manage in the Command field. Or, look at Current Cron Jobs that will permit you to delete or edit current jobs.

Cron Email Notifications

You can identify a specific email address where you intend to receive notices from the cPanel to confirm your tasks are already running. Majority of users may have tasks running every now and then that will swamp their inboxes with these notifications. Add this code at the end of your access to the command line:

       >/dev/null 2>&1

This step enables you to disable these warnings on a per-command arrangement. See to it your cron does not function too often since it can slow down the server and hold back data transfer to visitors.
