You also want to setup cron job on your server then you can follow this tutorial and let's implement it.

Step 1: Install Laravel 8

In this step, if you haven't laravel 8 application setup then we have to get fresh laravel 8 application. So run bellow command and get clean fresh laravel 8 application.

composer create-project --prefer-dist laravel/laravel blog

Step 2: Create New Command

In this step, we need to create our custom command. custom command will execute with task scheduling scron job. so, let's run bellow command to create new custom command.

php artisan make:command DemoCron --command=demo:cron

Now make some changes on Command file.

app/Console/Commands/DemoCron.php

<?php
   
namespace App\Console\Commands;
   
use Illuminate\Console\Command;
   
class DemoCron extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'demo:cron';
    
    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Command description';
    
    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }
    
    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        \Log::info("Cron is working fine!");
     
        /*
           Write your database logic we bellow:
           Item::create(['name'=>'hello new']);
        */
    }
}

Step 3: Register as Task Scheduler

In this step, we need to define our commands on Kernel.php file with time when you want to run your command like as bellow functions:

app/Console/Kernel.php

<?php
   
namespace App\Console;
    
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
    
class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        Commands\DemoCron::class,
    ];
     
    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('demo:cron')
                 ->everyMinute();
    }
     
    /**
     * Register the commands for the application.
     *
     * @return void
     */
    protected function commands()
    {
        $this->load(__DIR__.'/Commands');
     
        require base_path('routes/console.php');
    }
}

Step 4: Run Scheduler Command For Test

now we are ready to run our cron, so you can manually check using following command of your cron. so let's run bellow command:

php artisan schedule:run

After run above command, you can check log file where we already print some text. so open you your log file it looks like as bellow:

storage/logs/laravel.php

[2019-04-24 03:46:42] local.INFO: Cron is working fine!  
[2019-04-24 03:46:52] local.INFO: Cron is working fine!  
[2019-04-24 03:46:55] local.INFO: Cron is working fine!  
  

At last you can manage this command on scheduling task, you have to add a single entry to your server’s crontab file:

* * * * * php /path/to/artisan schedule:run 1>> /dev/null 2>&1
   
OR
  
* * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1

I hope it can help you...
