laravel无法运行计划的命令，而queue: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中的命令时间表无关，该时间表不起作用.但是在我的问题中，调度有效，但是它不能调用artisan命令.
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.
我使用laravel调度工匠命令.我像这样sudo -u www-data /var/www/market/artisan command:printer-serving 281H28从控制台直接运行命令.
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.
我知道它是有效的，因为我在命令的handle()函数条目处输入了Log::info('Working').
I know it works because, I've Log::info('Working') at the entry of the handle() function of the command.
当我使用laravel的计划时. cron运作良好，因为Log::info('command:printer-serving 281H28');以下的内容连续输出到控制台.
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.
但是artisan命令没有执行，它没有向控制台输出任何内容，也没有向DB写东西
在Kernel.php中
In the Kernel.php
<?php namespace App\Console;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
use Log;
class Kernel extends ConsoleKernel {
/**
* The Artisan commands provided by your application.
*
* @var array
*/
protected $commands = [
'App\Console\Commands\Inspire',
'App\Console\Commands\CommandPrinterServing',
];
/**
* Define the application's command schedule.
*
* @param \Illuminate\Console\Scheduling\Schedule $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();
}
}
命令名称，protected $signature = 'command:printer-serving {pid}';
注意
不管什么字符串，即使不是我在$schedule->command()函数中输入的命令，也都不会改变，也不会从cron日志或laravel日志中报告错误.
Note
No matter what string even not a command I put in $schedule->command() function, nothing will changes and not a error reported from the cron log or laravel log.
我想知道如何调试$schedule->command()函数.
I want to know how to debug the $schedule->command() function.
Cron文件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
奇怪的是，日志输出每3秒输出4个thme.
The weired thing is log output four thmes every 3 seconds.

我对日志频率感到困惑，所以我停止了cron和beantalkd.但是日志输出不会停止.甚至我停止了apache2，该日志保留输出.然后，我检查了php进程，并在命令ps aux | grep php的输出中找到了四个queue:listen --queue=xxxx --env=worker_env --delay=3.在这里，我找到了为什么以该频率输出日志，但我不知道为什么queue:listen执行schedule()函数作为此问题了解Laravel 5.2上的队列和调度程序.
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.
每次执行工匠命令sudo -u www-data /var/www/market/artisan xxxxx时，都会调用schedule()函数.如果命令是queue:listen(如sudo -u www-data /var/www/market/artisan queue:listen xxxxx)，则将定期调用schedule()函数.但是schedule()中的命令将无法运行，但Log::info()除外.仅当运行schedule:run命令时，工匠命令和schedule()中的Log::info()都将执行.
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.
推荐答案
花费一天的时间来搜索该问题，阅读laravel文档并进行许多测试.终于我明白了.
It costs me a day to google the issue, read laravel docs, and run many test. Finally I make it out.
Laravel的artisan queue:listen命令会定期在Kernel.php中调用schedule()，而它只在schedule()中运行Log::info()而不是$schedule->command()(这里我也很困惑).
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).
我有四个正在运行的队列，用于队列1 sudo -u www-data php artisan queue:work --queue=queue1 --env=worker_env --delay=3 --timeout=600.与queue2、3、4相同.因此schedule()中的Log::info()将每3秒执行四次.
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.
上面让我觉得时间表很好.实际上，不执行计划.我发现/etc/cron.minutely/printer-task-minute没有任何x特权，因此我为其添加了x特权.我发现我没有配置crontab文件，所以我将* * * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.minutely )添加到/etc/crontab(我不熟悉cron).
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).
解决方案:
像上面一样配置cron，或参考手册.
将queue:listen更改为queue:work(当更改为queue:work时，schedule()不会周期性地由队列执行，我在这里也不知道原因.).
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.).
