i'm trying to run lumen scheduler and i have used crontab for this purpose and setup a command like this

* * * * * cd /home/humzayun/fbapp && ea-php71 artisan schedule:run >> /dev/null 2>&1

before this i tried using

* * * * * cd /home/humzayun/fbapp && php artisan schedule:run >> /dev/null 2>&1

but in log file it was throwing errors

[2018-11-13 16:31:03] staging.ERROR: ErrorException: Undefined index:
argv in
/home/humzayun/fbapp/vendor/symfony/console/Input/ArgvInput.php:53

1 /home/humzayun/fbapp/artisan(34): SymfonyComponentConsoleInputArgvInput->__construct()

2 {main} {"exception":"[object] (ErrorException(code: 0): Undefined index: argv at

2 {main} "}

So after trying this all finally now my crontab is doing nothing.

my code in Kernel.php is

<?php



namespace AppConsole;



use FacebookFacebook;

use IlluminateConsoleSchedulingSchedule;

use LaravelLumenConsoleKernel as ConsoleKernel;

use PharIoManifestEmail;



class Kernel extends ConsoleKernel

{

    /**

     * The Artisan commands provided by your application.

     *

     * @var array

     */

    protected $commands = [

        //

    ];



    /**

     * Define the application's command schedule.

     *

     * @param  IlluminateConsoleSchedulingSchedule  $schedule

     * @return void

     */

    protected function schedule(Schedule $schedule)

    {

        $schedule->call(function (Facebook $facebook){

            Log::info($facebook->getDefaultAccessToken());

            echo " yayy here ";

        })->everyMinute();

    }

}

Now the issue is that log is reporting nothing.

but when i run this command using ssh it output
http://prntscr.com/lhxxjq

and my lumen log file shows

http://prntscr.com/lhxy4g

But by this cron command nothing is working out like i'm doing in ssh.
Any help will be regraded i shall be very thankful to you for help

You'll receive these argv errors when you're not executing the cli version of php. You should see (cli) when executing php -v:

# php -v

PHP 7.1.20 (cli) (built: Jul 25 2018 10:06:40) ( NTS )

If you see cgi or fcgi, then you're using the wrong binary.

When running commands in cron, it's best not to always redirect output to /dev/null and instead collect the stderr and stdout to review for errors. As indicated in the comments, ea-php71 was not in the $PATH. Using the full path to ea-php71 solved the OP's problem.
