How to automatically run custom module CRON only?

Question

I've to insert/update/delete some data in my custom tables in each 6HR. so i'm using a custom module with CRON and in that module i've written script to insert/update/delete the things.

So for automatically hitting the CRON as i R&D

(reference link:- https://www.cloudways.com/blog/magento-2-cron-job/) and found

that i need to follow following steps :-

1- Login on the server as Super User

2- from the CLI,i need to hit "crontab -e"

3- then,i need to set following in this file

*/1 * * * * php -c <ini-file-path> <your Magento install dir>/bin/magento cron:run

*/1 * * * * php -c <ini-file-path> <your Magento install dir>/update/cron.php

*/1 * * * * php -c <ini-file-path> <your Magento install dir>/bin/magento setup:cron:run

Where "ini-file-path" => https://nimb.ws/fx1p70

"your Magento install dir"=> you can get via DIR

Which is exactly working for me,but by doing this indexing,orders etc crons are also automatically running but i want to run automatically my custom module "custom_cronjob" CRON only

Here is the screenshot:- https://nimb.ws/zoVApY

How can i achieve the same and avoid other CRONs?

Please help me!!!

Answer 1

Use n98-magerun2: https://github.com/netz98/n98-magerun2

It has a command called sys:cron:run <job-code> that lets you run only a specific job.

If you want to run you cronjob every 6 hours, you could edit the crontab file like this:

0 */6 * * * php -c <ini-file-path> <magento-dir>/n98-magerun2.phar sys:cron:run <job-code>

Here is a etc/crontab.xml file that you can insert to run your cronjob every 6 hours via the default Magento 2 cron function:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
    <group id="default">
        <job name="my_cron_name" instance="Vendor\Module\Cron\File" method="execute">
            <schedule>0 */6 * * *</schedule>
        </job>
    </group>
</config>```

Create a custom cron job with custom cron group in your module. For more details plz visit: https://devdocs.magento.com/guides/v2.3/config-guide/cron/custom-cron-tut.html
