[英]How to pause a supervisor in Laravel Horizon
I have multiple supervisor in horizon, and they work normally, the problem is that I want to interact with them by my own web interface, and by interacting I mean pause
them and continue
(unpause them).我在地平线上有多个主管,他们工作正常,问题是我想通过我自己的 web 接口与他们进行交互,并且通过交互我的意思是
pause
他们并continue
(取消暂停他们)。
To do that I want to be able as much as possible, without using system (in artisan horizon:pause-supervisor
it sends posix_kill($supervisor->pid, 12))
.为此,我希望尽可能不使用系统(在
artisan horizon:pause-supervisor
中它发送posix_kill($supervisor->pid, 12))
。
I tried to instantiate the supervisor by doing this:我试图通过这样做来实例化主管:
class HorizonManager
{
private SupervisorRepository $supervisors;
private MasterSupervisorRepository $masters;
private WorkloadRepository $workload;
private RedisJobRepository $jobRepository;
private QueueManager $queueManager;
public function __construct(MasterSupervisorRepository $masters, SupervisorRepository $supervisors, WorkloadRepository $workload, RedisJobRepository $jobRepository, QueueManager $manager)
{
$this->masters = $masters;
$this->supervisors = $supervisors;
$this->workload = $workload;
$this->jobRepository = $jobRepository;
$this->queueManager = $manager;
}
public function pauseSupervisor(string $supervisorName){
$supervisor = $this->supervisors->find($supervisorName);
$supervisorOpt = new SupervisorOptions(...$supervisor->options);
$sup = new Supervisor($supervisorOpt);
$sup->pause();
$sup->persist();
return $this->supervisors->find($supervisorName);
}
}
In the return from the function, I have the supervisor paused, but it's not really paused (even If I persist the instantiate supervisor it's still running as a process)在 function 的返回中,我暂停了主管,但它并没有真正暂停(即使我坚持实例化主管它仍然作为一个进程运行)
For those interested I failed doing it by instanciating it so instead I send the command using artisan call:对于那些感兴趣的人,我通过实例化它失败了,所以我改为使用 artisan 调用发送命令:
define('SIGUSR2', 12);
Artisan::call('horizon:pause-supervisor', ['name'=>$supervisorName]);
$supervisor = $this->supervisors->find($supervisorName);
$supervisor->status = 'paused';
