Write console script by laravel

One ：
app\Console\Commands Create a script file in the directory TestConsole.php

<?php
namespace App\Console\Commands;

use Illuminate\Console\Command;
use App\Base\CommonPoolMethod;
// Connecting to the database can introduce database related classes 

class TestConsole extends Command
{
    
    use CommonPoolMethod;

    /** * The name and signature of the console command. * update：artisan Lower command group , You can use 【php artisan -v】 or 【php artisan list】 see  * test_function ： Explain the function of the command （ at will ） *  Full command 【php artisan update:test_function】 * @var string */
    protected $signature = 'update:test_function';
	
    /** * The console command description. * * @var string */
    protected $description = " Update test method ";

    /** * Create a new command instance. * * @return void */
    public function __construct()
    {
    
        parent::__construct();
    }



    public function handle()
    {
    
       // Scripting methods 
    }

}

Two ：laravel Execute... In the root directory artisan command 【php artisan update:test_function】

notes ： Error in execution of order 【SQLSTATE[HY000] [2002] No such file or directory 】
reason ： Not found mysql.sock file
solve ：
1： open MySQL Management tools , perform sql sentence 【show variables like ‘%sock%’】, Get a directory 【/Applications/MAMP/tmp/mysql/mysql.sock】

2： find ./config/database.php Medium unix_socket, modify 【‘unix_socket’ => ‘/Applications/MAMP/tmp/mysql/mysql.sock’】

perhaps

.env Corresponding DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock
