1hyperf生命周期

Hyperf 的指令管理預設由

symfony/console 
           

提供支援 (如果您希望更換該元件您也可以通過改變 skeleton 的入口檔案更換成您希望使用的元件)， 在執行

php bin/hyperf.php start 
           

後，将由

Hyperf\Server\Command\StartServer 
           

指令類接管，并根據配置檔案

config/autoload/server.php
           

内定義的 Server 逐個啟動

其實最開始的文檔已經寫清楚,隻是太着急沒時間看,到了後來才發現 衆裡尋他千百度,蓦然回首,那人卻在燈火闌珊處.

Hyperf\Server\Command\StartServer.php
           

public function __construct(ContainerInterface $container)
{
    $this->container = $container;
    parent::__construct('start');
    $this->setDescription('Start hyperf servers.');
}
           

這裡是定義start的地方

protected function execute(InputInterface $input, OutputInterface $output)
{
    $this->checkEnvironment($output);

    $serverFactory = $this->container->get(ServerFactory::class)
        ->setEventDispatcher($this->container->get(EventDispatcherInterface::class))
        ->setLogger($this->container->get(StdoutLoggerInterface::class));

    $serverConfig = $this->container->get(ConfigInterface::class)->get('server', []);
    if (! $serverConfig) {
        throw new InvalidArgumentException('At least one server should be defined.');
    }

    $serverFactory->configure($serverConfig);

    Runtime::enableCoroutine(true, swoole_hook_flags());

    $serverFactory->start();

    return 0;
}
           

這裡運作的時候可以看到 $output的内容

        }

...
           

并且要求至少啟動一個server,由配置檔案 config/autoload/server.php 定義的server逐個啟動,例如主程式啟動使用9501,websocket啟動使用9502,Grpc啟動使用9503...這樣服務依次啟動,互不影響,友善使用

而且這個操作預設是在入口檔案config/container.php裡面實作了的,也就是上文講到的重點
