* 檢視php artisan可用的命令

/opt/lampp/bin/php /home/ubuntu/easyeye/src/admin/artisan help

* 新增crontab任務

crontab -e

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
 

開啟後新增這一行

* * * * * /opt/lampp/bin/php /home/ubuntu/easyeye/src/admin/artisan schedule:run >> /dev/null 2>&1

注意最後面要新增一個空行

crontab: installing new crontab
new crontab file is missing newline before EOF, can't install.
Do you want to retry the same edit? (y/n) y
crontab: installing new crontab

列出當前的計劃任務

$ crontab -l
* * * * * /opt/lampp/bin/php /home/ubuntu/easyeye/src/admin/artisan help schedule:run >> /dev/null 2>&1

* 定義artisan命令

E:\easyeye\src\admin\app\Console\Commands\TestCommand.php

<?php
namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Facades\Log;

class TestCommand extends Command {
    /**
     * @var string
     * The console command name.
     * */
    protected $name = 'test:putcache';

    /**
     * @var string
     * The console command description.
     */
    protected $description = 'test controller';

    /**
     * Execute the console command.
     * @return mixed
     */
    public function handle() {
        $now = new \DateTime('now');
        Log::info("schedule task at " . $now->format('Y-m-d H:i:s'));
    }
}
 

** list artisan commands

/opt/lampp/bin/php /home/ubuntu/easyeye/src/admin/artisan list

** Run the scheduled commands

/opt/lampp/bin/php /home/ubuntu/easyeye/src/admin/artisan schedule:run

** 測試新增的artisan命令是否可用

 /opt/lampp/bin/php /home/ubuntu/easyeye/src/admin/artisan test:putcache

$ tail /storage/logs/lumen-`date +%F`.log  

# 這裡lumen log配置路徑 

預設是在 ./storage/logs/lumen.log

...
[2018-09-25 11:02:32] local.INFO: schedule task at 2018-09-25 11:02:32  

說明test:putcache這個artisan命令已經設定成功

* 新增lumen排程任務

./app/Console/Kernel.php

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Laravel\Lumen\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel {
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        \App\Console\Commands\TestCommand::class
    ];

    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule) {
        $schedule->command('test:putcache')->everyMinute();
    }
}

新增計劃任務還可以使用閉包

$schedule->call(function () {
    Log::info('任務排程');
})->everyMinute();

排程的時間可以有多種： 
->cron(‘* * * * *’); 在自定義Cron排程上執行任務 
->everyMinute(); 每分鐘執行一次任務 
->everyFiveMinutes(); 每五分鐘執行一次任務 
->everyTenMinutes(); 每十分鐘執行一次任務 
->everyThirtyMinutes(); 每三十分鐘執行一次任務 
->hourly(); 每小時執行一次任務 
->daily(); 每天凌晨零點執行任務 
->dailyAt(‘13:00’); 每天13:00執行任務 
->twiceDaily(1, 13); 每天1:00 & 13:00執行任務 
->weekly(); 每週執行一次任務 
->monthly(); 每月執行一次任務 
還有一下額外的方法，請參考：http://laravelacademy.org/post/235.html

* 執行計劃任務

Running scheduled command: '/opt/lampp/bin/php-7.2.8' artisan test:putcache > '/dev/null' 2>&1
