Cron documentation example contains files which I don't have

[pantaoran]

This page:

https://github.com/magento/devdocs/blob/develop/guides/v2.0/config-guide/cli/config-cli-subcommands-cron.md

contains instructions that don't work for me. There are three lines in the example:

* * * * * /usr/bin/php /var/www/magento2/bin/magento cron:run | grep -v "Ran jobs by schedule" >> /var/www/magento2/var/log/magento.cron.log
* * * * * /usr/bin/php /var/www/magento2/update/cron.php >> /var/www/magento2/var/log/update.cron.log
* * * * * /usr/bin/php /var/www/magento2/bin/magento setup:cron:run >> /var/www/magento2/var/log/setup.cron.log

However, for the second line, I don't have a directory {magento2_root}/update.
And for the third line, when I run that, in the log I get setup-cron.ERROR: Could not locate magento/magento2-base/composer.json file.

As my installation method I cloned the Magento2 repository and ran the installer. Is this why the regular instructions don't apply to me? Should this case be added to the documentation?

Thanks for pointing it out. I'll confirm the answer and get back to you ASAP.

@pantaoran You are correct. I updated the cron documentation here. Please take a look and close this issue if you're happy with the resolution.

Thanks for adding that.

Please note the following quote from my first post:

And for the third line, when I run that, in the log I get setup-cron.ERROR: Could not locate magento/magento2-base/composer.json file.

You didn't address that part. Is that not supposed to happen?

Would you mind pasting your current crontab and verifying that magento/magento2-base/composer.json exists?

[pantaoran]

I cannot find any directory called "magento2-base". Isn't this the same reason as the first problem?

[pantaoran]

To be more specific, the following command returns zero hits:

find myMagentoRoot -name "magento2-base" -type d

I now created a module with a crontab.xml that's supposed to execute something every minute, but it never gets executed. My cron job only runs bin/magento cron:run but I guess that is not enough?

How do I get this to work?

To fully answer your previous question, here is my cron command, which runs as the magento user (the variables are filled):

* * * * * cd /src/${PROJECT} && ${PHP} bin/magento cron:run | grep -v 'Ran jobs by schedule.' || true >> var/log/magento.cron.log

I'll try to answer your questions but please let me know whether or not this helps and I can try to get additional assistance.

If you don't have a magento2-base directory, then the error "Could not locate.." is normal.

Your crontab looks OK although I think you need a second line. Assuming that the environment variable $PHP is defined for the Magento file system user, it should work.

EDIT You also need to run bin/magento setup:cron:run because it's used to enable or disable modules using the Web Setup Wizard.

If your crontab.xml is located in the correct directory, and your module is enabled, it should work. Suggest you use the default group to start because it's easiest. I'm sure you've seen this page already.

Let me know if you have any better results with your custom module and I can look for additional help.

[pantaoran]

In your EDIT you recommend to also run bin/magento setup:cron:run, but that's exactly what I've been asking about because I don't think this works for me. I first run that command without cron just to see what it does, and its only result is the message setup-cron.ERROR: Could not locate magento/magento2-base/composer.json file.

You said that message was normal if I don't have that folder, but that seems to contradict your insisting on me running bin/magento setup:cron:run.

Anyway, you say that that is necessary to run the Web Setup Wizard which I don't use at all, so maybe I don't actually need it?

The rest of your assumptions are correct. My etc/crontab.xml looks like this (slightly anonymized) and I would expect it to run every minute, but after waiting for several minutes I cannot see the expected log messages (which I do see when I run it manually through a CLI command that I created to call the scheduleUpdate method):

<?xml version="1.0" encoding="UTF-8"?>
<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="custom_update_order_statuses" instance="MyCompany\MyModule\Model\StatusUpdater" method="scheduledUpdate">
            <schedule>* * * * *</schedule>
        </job>
    </group>
</config>

So in summary I still need help because my custom crontab doesn't seem to be working. Your advice at first seems contradictory and didn't really help :-(

I referred this question to engineering. Meanwhile, if you haven't done so already, you can ask this to a lot bigger audience by posting it on stackoverflow or magento.stackexchange.com.

Hi @pantaoran

This looks like a bug in the documentation and seems to be already fixed.
In your case (git clone) you will not have /update folder because it's separate repository and is not available for git-cloned version of Magento.

Update: magento/magento2-base is also available only for Composer-based installation.

@shiftedreality Thank you. Can you provide any guidance to his crontab.xml question?

@pantaoran Updated the cron setup page to remove the setup cron job for those that cloned GitHub.

@pantaoran I would like to ask you about few clarifications:

1. Did you clean cache?
2. Is your custom module registered in Magento
3. Are basic cron tasks works fine for you?
