如何在共享主机上运行队列工作器

问题描述

限时删除！！

我的Laravel应用程序具有排队的事件侦听器，我有还将cronjob设置为每分钟运行 schedule:run .

My Laravel application has a queued event listener and I have also set up the cronjob to run schedule:run every minute.

但是我不知道如何在后台持久运行 php artisan queue:worker 命令.我发现此线程投票最多的方法:

But I don't know how I can run the php artisan queue:worker command persistently in the background. I found this thread where it was the most voted approach:

$schedule->command('queue:work --daemon')->everyMinute()->withoutOverlapping();

但是，在不同线程上，人们抱怨上述命令创建了多个队列工作器.

However, on a different thread some people complained that the above-mentioned command creates multiple queue worker.

如何安全地运行队列工作器?

How can I safely run a queue worker?

推荐答案

从Laravel 5.7开始，有一个新的队列命令在空时停止工作:

Since Laravel 5.7, there's a new queue command to stop working when empty:

php artisan queue:work --stop-when-empty

由于这主要是用于电子邮件或少量小型工作，因此我将其放在cronjob上，以便每分钟运行一次.我说这并不是每分钟超过100个工作的解决方案，但可以处理我的电子邮件.发送电子邮件的时间大约每分钟5秒，具体取决于发送的电子邮件数量或工作量.

As this is mostly just for emails or few small jobs, I put it on a cronjob to run every minute. This isn't really a solution for more than 100 jobs per minute I'd say, but works for my emails. This will run about 5 seconds every minute just to send emails, depending on how many emails or how big the job.

1. 创建新命令: php artisan make:command SendContactEmails
2. 在 SendContactEmails.php 中，更改: protected $ signature ='emails:work';
3. 在 handle()方法中，添加:

1. Create new command: php artisan make:command SendContactEmails
2. In SendContactEmails.php, change: protected $signature = 'emails:work';
3. In the handle() method, add:

return $this->call('queue:work', [
    '--queue' => 'emails', // remove this if queue is default
    '--stop-when-empty' => null,
]);

1. 每分钟安排您的命令:

protected function schedule(Schedule $schedule)
{
    $schedule->command('emails:work')->everyMinute();
    // you can add ->withoutOverlapping(); if you think it won't finish in 1 minute
}

1. 更新您的cronjobs:

* * * * * /usr/local/bin/php /home/username/project/artisan schedule:run > /dev/null 2>&1
