Question

我有以下supervisor.conf用于运行作业：

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command= php artisan queue:work --sleep=5 --tries=5
autostart=true
autorestart=true
numprocs=4
stopwaitsecs=5
redirect_stderr=true
stdout_logfile=/home/ubuntu/laravel-worker.log

然后我执行以下工作：

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\Log;

class DelayJobTestJob  implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public function handle(): void
    {

        sleep(rand(5,6));
        Log::channel('jobs')->debug("Job Termination test jobId: ".$this->job->getJobId());
    }

}

然后我通过在修补程序上运行来模拟作业分配：

while(true){ App\Jobs\DelayJobTestJob::dispatch(); }

然后我尝试通过以下方式终止我的工作：

sudo supervisorctl stop laravel-worker:*

但是，即使在管理程序上，作业也已停止（根据日志）：

$ tail -f /home/vagrant/laravel-worker.log

我发现原因是因为jobs通道上的最后一次登录时间大于主管的登录时间，而12:08:02的时间磨合时间大于{5}的5个时间我期望上一份工作的秒差。

停止分发作业的唯一方法是运行一次：

11:58:49

你知道为什么会这样吗？

Answer 1

while (true) {
    App\Jobs\DelayJobTestJob::dispatch();
}

是一个无限循环，它将作业无休止地推送到队列中。

down命令虽然挂起了调度程序，所以它们停止运行。

为什么即使我停止了主管，laravel的工作也没有停止？
