If you want to run jobs from the internet or just from the local computer, Cron can help you. For more information how Cron can simplify your job scheduling, please have a look at the [raison d'être](#raison). - Homepage: - Github: - API: --- - [Raison d’être](#raison) - [Installation](#installation) - [Configuration](#configuration) - [Example](#example) - [API](#api) - [Add a cron job](#addjob) - [Remove a cron job](#removejob) - [Enable / disable a cron job](#enabledisable) - [Run the cron jobs](#runjob) - [Enable / disable Laravel logging](#enablelarvellogging) - [Set a Monolog logger](#setlogger) - [Disable database logging](#disabledatabaselogging) - [Log only error jobs to database](#logonlyerrorjobstodatabase) - [Delete old database entries](#deleteolddatabaseentries) - [Prevent overlapping](#preventoverlapping) - [Events](#events) - [Commands](#commands) - [Reset Cron](#reset) - [Frequently Asked Questions](#faq) - [Changelog](#changelog) --- Raison d’être ------------- [](#raison-dêtre) ### Simplicity [](#simplicity) The aim is to create a simple way to define cron jobs with Laravel. Creating cron jobs with Cron is easy because this tool provides you with a lot of events that you can use to manage all your jobs. For creating a job you only need a job name, a cron expression and a function which will be called as soon as the time has come. Of course PHP is only running if you call it, so you need something in addition which starts Cron. ### Accessibility [](#accessibility) The Cron starting call can be executed from the same machine where your Laravel is located (for example with crontab) or from everywhere on the internet (for example from a web cron service) - it is just a command execution or route call. ### Centralization [](#centralization) The Cron management is centralized at a single point in your application. You define all jobs in PHP and don't have to use other tools. Deactivating or removing a Cron job is only a PHP function call away. ### Platform independency [](#platform-independency) Laravel is a great way to build small and big web applications. But not every application platform runs on a server which allows unix shell access. For these applications Cron provides the possibility to use an external web cron service to start Cron. If you have shell access - great, you can make use of Cron's command to start the job management. ### Monitoring [](#monitoring) If something went wrong with your jobs, Cron will inform you. Next to the logging to Monolog, to the Laravel logging facility and to the database, you can add an event listener to get information about error jobs or successfully executed jobs. After execution you will receive a detailed report about the Cron run. With the power of PHP and events you can send a mail, a notification or anything else if anything happens. Cron is talkative like your grandma. ### My personal comfort zone [](#my-personal-comfort-zone) At last, Cron is my personal way to manage job scheduling. I am a web application developer, not an infrastructure guy. I like to handle things in PHP and not in the shell. I want to deploy my application to another server without worrying if I have access to crontab or other Linux tools. I really like Laravels event functionality but don't like Laravel commands. Cron management should be easy and powerful at the same time. And finally, I love to handle things at a single place in my application without using the shell or write a PHP file for each job. Cron is the try to manage cron jobs without headaches. --- Installation ------------ [](#installation) ### Laravel 5 [](#laravel-5) 1. Add `"liebig/cron": "dev-main"` to your `/path/to/laravel/composer.json` file at the `"require":` section (Find more about composer at ) 2. Run the `composer update liebig/cron --no-dev` command in your shell from your `/path/to/laravel/` directory 3. If you're on Laravel 5.4 or earlier, add `'Liebig\Cron\Laravel5ServiceProvider'` to your `'providers'` array in the `/path/to/laravel/config/app.php` file 4. Migrate the database with running the command `php artisan migrate --path=vendor/liebig/cron/src/migrations` 5. Publish the configuration file with running the command `php artisan vendor:publish` - now you find the Cron configuration file at `/path/to/laravel/config/liebigCron.php` and this file won't be overwritten at any update 6. Now you can use `Cron` everywhere for free ### Laravel 4 [](#laravel-4) 1. Add `"liebig/cron": "dev-main"` to your `/path/to/laravel/composer.json` file at the `"require":` section (Find more about composer at ) 2. Run the `composer update liebig/cron --no-dev` command in your shell from your `/path/to/laravel/` directory 3. Add `'Liebig\Cron\CronServiceProvider'` to your `'providers'` array in the `/path/to/laravel/app/config/app.php` file 4. Migrate the database with running the command `php artisan migrate --package="liebig/cron"` 5. Publish the configuration file with running the command `php artisan config:publish liebig/cron` - now you find the Cron configuration file at `/path/to/laravel/app/config/packages/liebig/cron` and this file won't be overwritten at any update 6. Now you can use `Cron` everywhere for free --- Configuration ------------- [](#configuration) Cron is designed to work out of the box without the need of configuration. To enable this a few default values are set. To change Cron's default settings there are two possibilities. ### Set methods [](#set-methods) You can use the Cron set methods (e.g. `setDatabaseLogging`, `setRunInterval`) to change Cron's behaviour. This changes are temporary and the set methods have to be called every time. ### Config file [](#config-file) The behaviour values will be loaded from a config file. You can change this values easily by editing in Laravel 5 the `/path/to/laravel/app/config/liebigCron.php` file and in Laravel 4 the `/path/to/laravel/app/config/packages/liebig/cron/config.php` file. This is the more permanent way. If you only want to change settings for one run with conditions, we recommend to use the setter methods. **NOTE**: All values set via method will overwrite the values loaded from config file. --- Example ------- [](#example) ### Cron [](#cron) If you use Cron's integrated route or command, you only need to listen for the `cron.collectJobs` event. The best place to do this is in Laravel 5 the `/path/to/laravel5/app/Providers/AppServiceProvider.php` file at the `boot` method and in Laravel 4 the `/path/to/laravel/app/start/global.php` file. #### Laravel 5 - AppServiceProvider.php [](#laravel-5---appserviceproviderphp) ```
