Magento Cron and How to Configure automatic job run

Magento Cron, In today’s Topic we will cover about Magento cron and how we can setup to run automatic.

Magento Cron is one type of scheduled job which runs on a particuler defined time interval

Cron Job can run every seconds , every minutes , every hours or so.

In Magento many features requires atleast one cron job which runs on a particular scheduled time interval to fullfill the requirement.

Some of the Magento activities are as below which are working based on crons

  • Indexer
  • Magento All Emails
  • Magento Mysql message queues
  • Google Sitemaps
  • Newsletters and many more

You can also create your own custom cron job for your module.

First you need to create your custom module

Now create crontab.xml in etc folder and add below code

<config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
    <group id="default">         
        <job instance="CreatesWowTech\ModuleName\Cron\CustomCron" method="execute" name="createswowtech_customcron">
            <schedule>*/5 * * * *</schedule>

Here group id = “default” is a default group for all crons.

instance : Here you need to define your class path

method : here you need to define your method name which will be call once cron will run

name : this will be your cron unique name

schedule : Here you need to define your cron expression , you can generate cron expression as per your requirement from here

Now you need to create class file CustomCron.php under CreatesWowTech\ModuleName\Cron Folder and add below code

namespace CreatesWowTech\ModuleName\Cron;

class CustomCron
    public function execute()
         // Your Business Logic
}//end class

Cron Group

Cron group helps to process multiple cron at a time. Most magento crons use default group.

To define new cron group create crongroup.xml and add below code

    <group id="custom_group_name">

So your crontab.xml file look like as below

<config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
    <group id="custom_group_name">         
        <job instance="CreatesWowTech\ModuleName\Cron\CustomCron" method="execute" name="createswowtech_customcron">
            <schedule>*/5 * * * *</schedule>
