Run and Create Cron job

Please follow the this tutorial if you wish to start the cron job program

Create a class within the “Cron” folder
Manually setup the cron schedule by using PHP: bin/magento cron:run
Find a log in the var/log/system.log after the cronjob has run.
Login to Magento 2 Admin panel, do as the path: Stores > Configuration > Advanced > System, then changing scheduler settings per cron group.
Finally, run cron from the command line:

magento cron:run [–group=”<cron group name>”]

Now, We will add a custom cron in HelloWorld module.

Create crontab.xml

File: app/code/Magemonkeys/HelloWorld/etc/crontab.xml

Content would be

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
	<group id="default">
		<job instance="Magemonkeys\HelloWorld\Cron\Test" method="execute" name="magemonkeys_helloworld_cron">
			<schedule>* * * * *</schedule>
		</job>
	</group>
</config>

<?xml version="1.0" ?>

</job>

</group>

</config>

group id is your cron group name. You can run only cron for single group at a time.
job instance is class to be instantiated (classpath).
job method is method in job instance to call.
job name is Unique ID for this cron job.
schedule is schedule in cron format. The following graph shows what it consists of:

* * * * * command to be executed
| | | | |
| | | | +----- Day of week (0 - 7) (Sunday=0 or 7)
| | | +------- Month (1 - 12)
| | +--------- Day of month (1 - 31)
| +----------- Hour (0 - 23)
+------------- Minute (0 - 59)

* * * * * command to be executed

| | | | |

| | | | +----- Day of week (0 - 7) (Sunday=0 or 7)

| | | +------- Month (1 - 12)

| | +--------- Day of month (1 - 31)

| +----------- Hour (0 - 23)

+------------- Minute (0 - 59)

In crontab.xml, we have defined job
instance can be Magemonkeys\HelloWorld\Cron\Test.

Create Test.php

File: app/code/Magemonkeys/HelloWorld/Cron/Test.php

Content would be:

<?php

namespace Magemonkeys\HelloWorld\Cron;

class Test
{

	public function execute()
	{

		$writer = new \Zend\Log\Writer\Stream(BP . '/var/log/cron.log');
		$logger = new \Zend\Log\Logger();
		$logger->addWriter($writer);
		$logger->info(__METHOD__);

		return $this;

	}
}

<?php

namespace Magemonkeys\HelloWorld\Cron;

class Test

{

public function execute()

{

$writer = new \Zend\Log\Writer\Stream(BP . '/var/log/cron.log');

$logger = new \Zend\Log\Logger();

$logger->addWriter($writer);

$logger->info(__METHOD__);

return $this;

}

All done, please flush cache and run magento cron:run –group=”default” from the command line.

To check whether the Cron is working properly, go to var/log/cron.log of your store, and you will see the text Magemonkeys\HelloWorld\Cron\Test::execute in it.
