to the require section of your composer.json.

Configuration

Database Migrations

Before using this extension, we'll also need to prepare the database.

php yii migrate/up --migrationPath=@yii2mod/cron/migrations

Error Handler and File Mutex Setup

Error handler must be defined inside console config, it will be used to log exceptions into database.

FileMutex implements mutex "lock" mechanism via local file system files.

Add the following code to your console application configuration:

'components' => [
    'errorHandler' => [
        'class' => 'yii2mod\cron\components\ErrorHandler',
    ],
    'mutex' => [
        'class' => 'yii\mutex\FileMutex'
    ],
],

Usage

1. To access the list of executed commands, you need to define CronLogAction in any controller (for example /modules/admin/SettingsController.php):

    public function actions()
    {
        return [
            'cron' => 'yii2mod\cron\actions\CronLogAction',
            // Also you can override some action properties in following way:
            'cron' => [
                'class' => 'yii2mod\cron\actions\CronLogAction',
                'searchClass' => [
                    'class' => 'yii2mod\cron\models\search\CronScheduleSearch',
                    'pageSize' => 10
                ],
                'view' => 'custom name of the view, which should be rendered.'
            ]
        ];
    }

This action is used to view list of executed commands: http://project.com/admin/settings/cron

1. To log cron actions you should add behavior to all commands that should be logged. In the following example CronLoggerBehavior will be log the index action.

namespace app\commands;

use yii\console\Controller;

/**
 * This command echoes the first argument that you have entered.
 *
 * This command is provided as an example for you to learn how to create console commands.
 *
 */
class HelloController extends Controller
{
    public function behaviors()
    {
        return [
            'cronLogger' => [
                'class' => 'yii2mod\cron\behaviors\CronLoggerBehavior',
                'actions' => ['index']
            ],
            // Example of usage the `MutexConsoleCommandBehavior`
            'mutexBehavior' => [
                'class' => 'yii2mod\cron\behaviors\MutexConsoleCommandBehavior',
                'mutexActions' => ['index'],
                'timeout' => 3600, //default 0
            ]
        ];
    }

    /**
     * This command echoes what you have entered as the message.
     * @param string $message the message to be echoed.
     */
    public function actionIndex($message = 'hello world')
    {
        echo $message . "\n";
    }
}
