Task Scheduling

Introduction to Cronjob Management

Managing scheduled tasks on your server involved manually editing the cron configuration for each task. This method is inconvenient since it lacks source control and requires SSH access to the server for changes. However, using a task scheduler simplifies this by requiring just one crontab entry.

Quick Start: Setting up the Scheduler

To set up a task scheduler, you only need to add a single crontab entry. To run bin/cronjob.php every minute, append the following line to your server’s crontab:

* * * * * /usr/bin/php /var/www/example.com/bin/cronjob.php 1>> /dev/null 2>&1

Now your scheduler is operational, and you can add new jobs without modifying the crontab.

Recommended Libraries for Cronjob Scheduling

Here are some recommended libraries to define and manage your scheduled tasks:

• Cron/Cron
• PHP Cron Scheduler
• Jobby

Resource Locking

Resource locks ensure exclusive access to a shared resource, preventing multiple instances of a cronjob or console command from running simultaneously.

For implementing resource locks, consider using The Lock Component by Symfony.

By employing the techniques outlined above, you can easily manage and coordinate your scheduled tasks.
