laravel 无法运行预定命令，而 queue:listen 定期运行 schedule() [英] laravel cannot run scheduled command, while queue:listen run schedule() periodically

问题描述

注意:我的问题与 Laravel 中的命令计划 哪个计划不起作用无关.但在我的问题中，调度有效，但它不能调用工匠命令.

我使用 laravel 调度 artisan 命令.我直接从控制台运行命令，例如 sudo -u www-data/var/www/market/artisan command:printer-serving 281H28.

我知道它有效，因为我在命令的 handle() 函数的入口处设置了 Log::info('Working').p>

当我使用 laravel 的调度时.并且 cron 运行良好，因为 Log::info('command:printer-serving 281H28'); 将内容连续输出到控制台.

但是 artisan 命令没有执行，它没有向控制台输出任何东西，也没有向数据库写入任何东西

在kernel.php中

command('inspire')->hourly();Log::info('command:printer-serving 281H28');$schedule->command('command:printer-serving --force 281H28')->everyMinute();//$schedule->command('printer-serving')->everyMinute();//$schedule->command(CommandPrinterServing::class, ['281H28'])->everyMinute();}}

命令名称，protected $signature = 'command:printer-serving {pid}';

注意无论我在 $schedule->command() 函数中输入什么字符串，甚至不是命令，都不会发生任何变化，也不会从 cron 日志或 laravel 日志中报告错误.

我想知道如何调试$schedule->command()函数.

我对日志频率感到困惑，所以我停止了 cron 和 beanstalkd.但是日志输出并没有停止.即使我停止了 apache2，日志保持输出.然后查看php进程，发现命令ps aux |的输出中有四个queue:listen --queue=xxxx --env=worker_env --delay=3grep php.在这里我找到了为什么以那个频率输出日志，但是我不知道为什么 queue:listen 执行 schedule() 函数作为这个问题 了解 Laravel 5.2 上的队列和调度程序.

<小时>

每次我执行一个工匠命令 sudo -u www-data/var/www/market/artisan xxxxx 都会调用一次 schedule() 函数.如果命令是 queue:listen 像 sudo -u www-data/var/www/market/artisan queue:listen xxxxx 则 schedule() 函数将被定期调用.但是 schedule() 中的命令不会运行，除了 Log::info().只有在运行 schedule:run 命令时，artisan 命令和 schedule() 中的 Log::info() 都会执行.

解决方案

我花了一天时间搜索问题、阅读 laravel 文档并运行许多测试.终于搞定了.

Laravel 的 artisan queue:listen 命令会定期调用 Kernel.php 中的 schedule()，而它只运行 Log::info() 在 schedule() 而不是 $schedule->command()(这里我也很困惑).p>

我有四个队列正在运行，用于 queue1 sudo -u www-data php artisan queue:work --queue=queue1 --env=worker_env --delay=3 --timeout=600.queue2,3,4 也一样.所以 schedule() 中的 Log::info() 会每 3 秒执行 4 次.

以上让我觉得日程安排很好.实际上，调度没有被执行.我发现 /etc/cron.minutely/printer-task-minute 没有 x 权限，所以我为其添加了 x 权限.而且我发现我没有配置crontab文件，所以我添加了 * * * * * root test -x/usr/sbin/anacron ||( cd/&& run-parts --report/etc/cron.minutely ) 到 /etc/crontab(我对 cron 不熟悉).

解决方案:
 像上面一样配置 cron，或者参考手册.
 将queue:listen改为queue:work(改为queue:work时，schedule()不会执行通过定期排队，我也不知道这里的原因.).

Note: My question has nothing to do with Command schedule in Laravel which schedule not work. But in my question the scheduling works, but it cannot call the artisan command.

I use laravel scheduling artisan command. I run the command directly from the console like this sudo -u www-data /var/www/market/artisan command:printer-serving 281H28.

I know it works because, I've Log::info('Working') at the entry of the handle() function of the command.

While when I use laravel's scheduling. And the cron works well, for below Log::info('command:printer-serving 281H28'); output the content to the console continuously.

But the artisan command not executed, it output nothing to the console, and not write something to the DB

In the Kernel.php

<?php namespace AppConsole;

use IlluminateConsoleSchedulingSchedule;
use IlluminateFoundationConsoleKernel as ConsoleKernel;
use Log;

class Kernel extends ConsoleKernel {

    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        'AppConsoleCommandsInspire',
        'AppConsoleCommandsCommandPrinterServing',
    ];

    /**
     * Define the application's command schedule.
     *
     * @param  IlluminateConsoleSchedulingSchedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('inspire')->hourly();
        Log::info('command:printer-serving 281H28');
        $schedule->command('command:printer-serving --force 281H28')->everyMinute();
        //$schedule->command('printer-serving')->everyMinute();
        //$schedule->command(CommandPrinterServing::class, ['281H28'])->everyMinute();
    }

}

Command name, protected $signature = 'command:printer-serving {pid}';

Note No matter what string even not a command I put in $schedule->command() function, nothing will changes and not a error reported from the cron log or laravel log.

I want to know how to debug the $schedule->command() function.

Cron file vi /etc/cron.minutely/printer-task-minute

#!/bin/sh
cd /var/www/market
sudo -u www-data ./artisan command:regen-htaccess
#sudo -u www-data ./artisan schedule:run >> /dev/null 2>&1
sudo -u www-data ./artisan schedule:run

The weired thing is log output four thmes every 3 seconds.

I'm puzzled about the log frequency, so I stop cron and beanstalkd. But the log output doesn't stop. Even I stop apache2, the log keeping output. Then I check the php process, and find there are four queue:listen --queue=xxxx --env=worker_env --delay=3 in the output of command ps aux | grep php. Here I found why the log output in that frequency, but I don't know why queue:listen execute the schedule() function as this question Understanding Queues and Scheduler on Laravel 5.2.

---

Each time I executed a artisan command sudo -u www-data /var/www/market/artisan xxxxx the schedule() function will be called one time. And if the command is queue:listen like sudo -u www-data /var/www/market/artisan queue:listen xxxxx the schedule() function will be called periodically. But the command in the schedule() will not run, except the Log::info(). Only when run schedule:run command, both the artisan command and Log::info() in schedule() will executed.

解决方案

It costs me a day to google the issue, read laravel docs, and run many test. Finally I make it out.

Laravel's artisan queue:listen command call the schedule() in the Kernel.php periodically, while it only run the Log::info() in the schedule() not the $schedule->command()(Here I'm also confused).

I've four queue running, for queue1 sudo -u www-data php artisan queue:work --queue=queue1 --env=worker_env --delay=3 --timeout=600. Same with queue2, 3, 4. So the Log::info() in the schedule() will executed four times every 3 seconds.

Above make me thought the schedule works well. Actually, the schedule is not executed. I found /etc/cron.minutely/printer-task-minute have no x privilege, so I add the x privilege for it. And I found I didn't config the crontab file, so I add * * * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.minutely ) to /etc/crontab(I'm not familar with cron).

Solution:
  Config the cron like above, or refer to the manual.
  Change queue:listen to queue:work(When changed to queue:work, schedule() will not executed by queue periodically, I also don't know the reason here.).
