How to properly set up Cron?

Question

PHP

Hello, how to set up Cron correctly? You need to run the script every 15 minutes. I do this but it doesn't work for some reason.
/home/****/public_html/****.ru/twitter/twit.php

Answer 1

#> crontab -e
and add to the end:
*/15 * * * * /usr/bin/php /path/to/your/script

Answer 2

Because you didn't specify a run interval. Read about cron file syntax.
If it’s hard to figure it out right away, then use generators.
cron.nmonitoring.com/cron-generator.html

Answer 3

That's the problem, everything is set up

Answer 4

do better

cd /home/****/public_html/****.ru/twitter/; /usr/bin/php twit.php

Answer 5

nano /etc/crontab
*/15 * * * * php /home/****/public_html/****.ru/twitter/twit.php No
