Magento 2 for cronjob

Question

This may sound like a dumb question but I really don't understand it. For example, Magento 2 has been saying to make sure "Magento cron job is running".

Create the cron job
To create a cron job as the Magento file system owner, enter the following command as a user with root privileges:
crontab -u <Magento file system owner user name> -e
Then write in the file:
"path-to-binary" -c "ini-file-path" "your Magento install dir"/bin/magento cron:run [>> "log-file"&]
"path-to-binary" -c "ini-file-path" "your Magento install dir"/update/cron.php [>> <log-file>&]
<path-to-binary> -c "ini-file-path" "your Magento install dir"/bin/magento setup:cron:run [>> "log-file"&]*

As I said before, this was an example because my problem is that I do not know where to write those commands. It always says to write this command or write the other, but I can't find where I am supposed to put them.

UPDATE:
I have access to cPanel to manage my server and use FTP to upload the files.

Answer 1

There is no place to "put" the crontab. You run the crontab command as root and cron starts running. You don't have to change to a directory but you do have to create cron as the correct user.

Answer 2

On a server you would enter those in the crontab command line tool via crontab -e but since you're using Windows please read this answer. It describes how you create a task in Windows Task Scheduler.

Optionally to test the cron you can also call cron.php from your browser

Answer 3

The Magento2 documentation is describing how to set up cronjobs on a Linux machine when you have access to a terminal and can type these commands on a command line.

In your case, this is not possible. You have to set the cronjobs via your cPanel. I'm sure cPanel provides manuals/tutorials for that (I Googled and found this).

See also this question concerning cPanel and magento-1.7 cronjob.

There's some placeholders in the part of the documentation that you have quoted and the documentation explains what you need to put there. Of course you cannot enter the commands written there to find your PHP binary or your php.ini, so you need to Google some more to find out where they are on your server.
