背景

公司准备引入swoole和rabbitmq来处理公司业务。因此，我引入hyperf框架，想用swoole的多进程来实现。

自定义启动服务封装
<?php
/**

基础process封装

此处可以用hyperf框架自带的，也可以自己封装

<?php

declare (strict_types = 1);

namespace App\Process;

use Swoole;
use Swoole\Process\Pool;

abstract class BaseProcess {

    /**
     * 进程数
     * @var integer
     */
    public $nums = 0;

    /**
     * 进程名称
     * @var string
     */
    public $name = '';

    /**
     * 是否启用协程
     * @var bool
     */
    public $enableCoroutine = true;

    /**
     * 是否随进程启动服务
     * @var bool
     */
    public $isEnable = true;

    protected $isRunning = true;

    protected $process;



    static $signal = 0;

    function __construct() {
        //进程自动命名
        if (empty($this->name)) {
            $this->name = trim(str_replace('\\', '.', str_replace(__NAMESPACE__, '', get_called_class())), '.');
        }
    }

    final public function handle(Pool $pool, int $workerId): void {

        try {

            $this->processInit($pool->getProcess());

            $this->beforeRun();

            while (true) {
                //进程结束信号
                if (BaseProcess::$signal === SIGTERM) {
                    $this->onProcessExit();
                    break;
                }

                $this->run();
            }
        } catch (\Throwable $e) {
            throw $e;
        }

    }

    protected function onProcessExit() {
        $this->isRunning = false;
    }

    protected function processInit($process) {

        $this->process = $process;

        echo "process {$this->name} start, pid: " . getmypid().PHP_EOL;

        //注册信号处理器，实现优雅重启(等待任务执行完后或者等待超时)
        pcntl_signal(SIGTERM, function () {
            BaseProcess::$signal = SIGTERM;
            $maxWaitTime = config('server.settings.max_wait_time', 5);
            $sTime = time();
            //检查进程任务状态
            Swoole\Timer::tick(500, function () use ($sTime, $maxWaitTime) {

                $coStat = \Swoole\Coroutine::stats();
                //如果主循环结束，且其它协程任务执行完，清理定时器以退出进程
                if (!$this->isRunning && $coStat['coroutine_num'] <= 1) {
                    Swoole\Timer::clearAll();
                    $this->process->exit();
                }
                //等待超时，强制结束进程
                elseif (time() - $sTime >= $maxWaitTime) {

                    Swoole\Timer::clearAll();
                    if ($this->isRunning) {
                        $this->onProcessExit();
                    }
                    $this->process->exit();
                }
            });
        });

    }

    public static function setProcessName(string $name) {
        swoole_set_process_name(env('APP_NAME', 'app') . '.taskProcess.' . $name);
    }

    /**
     * 事件循环前调用
     * @return [type] [description]
     */
    abstract function beforeRun();

    /**
     * 事件循环，注意这里不能使用死循环
     * @return [type] [description]
     */
    abstract function run();

}

在配置中进程需要执行的服务

在这里插入图片描述

以守护进程方式启动服务
php bin/hyperf.php task start -d

在这里插入图片描述
查看进程命令

ps -ef|grep taskProcess

在这里插入图片描述

疑惑

这次封装还存在两个点需要完善！！！
1.重复执行：

php bin/hyperf.php task start -d

会启动多个manager进程

2、没有封装查看进程状态的status方法文章来源地址https://uudwc.com/A/Y6d4J
