Cron Jobs
In Plesk, cron jobs are called 'Scheduled Tasks'.
Cron Jobs Affect Account Load
Scheduled Tasks count towards your total account load. This means that running too many cron jobs or starting a cron job to run every 1 minute risks your account getting suspended for high server usage on Tommy and Johnny, or charged for overages on Morty.
Setting up a Scheduled Task
To access the cron job section, navigate to:
Login > Plesk > Websites & Domains > [ domain ] > Scheduled Tasks > 'Add Task'
Cron Jobs are chrooted
Scheduled Tasks run in a chroot environment with limited access to binaries and executables for security reasons.
This means you cannot directly access certain programs or scripts outside of your home directory.
Working Around the chroot
Some options to work around the chroot environment when setting up a Scheduled Task include:
Flask Endpoint
Set up a Flask application and create an endpoint like 'domain.helioho.st/update', then use the "Fetch a URL" option inside Scheduled Tasks to access it via 'https'.
If you're new to Flask or want a more detailed guide, check out this Flask tutorial to help you get started.
Python
Set up a Python script in the 'cgi-bin' directory, then use the "Fetch a URL" option inside Scheduled Tasks to access the file via 'https'.
If you're new to Python or want a more detailed guide, check out this Python tutorial to help you get started.
