Hyperf 的命令管理默认由
symfony/console
提供支持 (如果您希望更换该组件您也可以通过改变 skeleton 的入口文件更换成您希望使用的组件), 在执行
php bin/hyperf.php start
后,将由
Hyperf\Server\Command\StartServer
命令类接管,并根据配置文件
config/autoload/server.php
内定义的 Server 逐个启动
其实最开始的文档已经写清楚,只是太着急没时间看,到了后来才发现 众里寻他千百度,蓦然回首,那人却在灯火阑珊处.
Hyperf\Server\Command\StartServer.php
public function __construct(ContainerInterface $container)
{
$this->container = $container;
parent::__construct('start');
$this->setDescription('Start hyperf servers.');
}
这里是定义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;
}
这里运行的时候可以看到 $output的内容

并且要求至少启动一个server,由配置文件 config/autoload/server.php 定义的server逐个启动,例如主程序启动使用9501,websocket启动使用9502,Grpc启动使用9503...这样服务依次启动,互不影响,方便使用
而且这个操作默认是在入口文件config/container.php里面实现了的,也就是上文讲到的重点
