I have a very large cron job that need to be carry out, but server cannot handle it due to memory leaks, so i follow the suggestion to use laravel Queue, and because i can't always run php artisan queue:work, so i wrote a scheduled queue command that trigger every 5 minutes, but the queue not working unless i manual trigger it on server.

Here is my command for queue:

<?php



namespace AppConsoleCommands;



use IlluminateConsoleCommand;



class EnsureQueueListenerIsRunning extends Command

{

    /**

     * The name and signature of the console command.

     *

     * @var string

     */

    protected $signature = 'queue:checkup';



    /**

     * The console command description.

     *

     * @var string

     */

    protected $description = 'Ensure that the queue listener is running.';



    /**

     * Create a new command instance.

     *

     * @return void

     */

    public function __construct()

    {

        parent::__construct();

    }



    /**

     * Execute the console command.

     *

     * @return mixed

     */

    public function handle()

    {

        //

        $this->startQueueListener();

        if ( ! $this->isQueueListenerRunning()) {

            $this->comment('Queue listener is being started.');

            $pid = $this->startQueueListener();

            $this->saveQueueListenerPID($pid);

        }

        $this->comment('Queue listener is running.');

    }



    /**

     * Check if the queue listener is running.

     *

     * @return bool

     */

    private function isQueueListenerRunning()

    {

        if ( ! $pid = $this->getLastQueueListenerPID()) {

            return false;

        }

        $process = exec("ps -p $pid -opid=,cmd=");

        //$processIsQueueListener = str_contains($process, 'queue:listen'); // 5.1

        $processIsQueueListener = ! empty($process); // 5.6 - see comments

        return $processIsQueueListener;

    }

    /**

     * Get any existing queue listener PID.

     *

     * @return bool|string

     */

    private function getLastQueueListenerPID()

    {

        if ( ! file_exists(__DIR__ . '/queue.pid')) {

            return false;

        }

        return file_get_contents(__DIR__ . '/queue.pid');

    }

    /**

     * Save the queue listener PID to a file.

     *

     * @param $pid

     *

     * @return void

     */

    private function saveQueueListenerPID($pid)

    {

        file_put_contents(__DIR__ . '/queue.pid', $pid);

    }

    /**

     * Start the queue listener.

     *

     * @return int

     */

    private function startQueueListener()

    {

        //$command = 'php-cli ' . base_path() . '/artisan queue:listen --timeout=60 --sleep=5 --tries=3 > /dev/null & echo $!'; // 5.1

        $command = 'php artisan queue:work --timeout=60 --sleep=5 --tries=3 > /dev/null & echo $!'; // 5.6 - see comments

        $pid = exec($command);

        return $pid;

    }

}

Here is the kernel:

$schedule->command('queue:checkup')->everyFiveMinutes();

What should i do to make it work?

if you want to set the crone job to run automatically without initiating using command.**

go to your terminal: and run this command

crontab -e

This will open server crontab file, paste this code inside, save it and exit

* * * * * php /path/to/artisan schedule:run >> /dev/null 2>&1
