composer require hyperf/signal

发布配置

config/autoload/signal.php

<?php

declare(strict_types=1);
return [
    'handlers' => [
        // 这里我们自己实现, 所以注释
        // Hyperf\Signal\Handler\WorkerStopHandler::class => PHP_INT_MIN,
    ],
    // 收到信号后等待时间
    'timeout' => 5.0,

自定义进程信号处理器

<?php

use Hyperf\Process\ProcessManager;
use Hyperf\Signal\Annotation\Signal;
use Hyperf\Signal\SignalHandlerInterface;

#[Signal]
class ProcessStopHandler implements SignalHandlerInterface

    {
        return [

        ];
    }

    public function handle(int $signal): void
    {
        ProcessManager::setRunning(false);
    }

自定义work进程信号处理器

        }

        // shutdown => https://wiki.swoole.com/#/server/methods?id=shutdown 直接kill -15 不触发后续动作
        // stop => https://wiki.swoole.com/#/server/methods?id=stop 使当前 Worker 进程停止运行，并立即触发 onWorkerStop 回调函数。

        //  $this->container->get(Server::class)->shutdown();
