如何用RoadRunner加速Laravel应用

RoadRunner是一个用Go语言实现的高性能PSR-7服务器，你没看错，是Go语言实现的。

RoadRunner首先用Go实现了一个高性能的服务器，然后通过goridge IPC把请求转发给多个PHP CLI Worker，Worker会把请求重新封装成PSR-7 Request交给框架进行处理。

娱乐测试

使用siege测试Laravel的Welcome页面，250个并发用户，持续30秒，对比Nginx + FPM和RoadRunner。

Nginx + FPM：
$ siege --no-parser -c 250 -t 30s http://127.0.0.1:3000/ > /dev/null
** SIEGE 4.0.4
** Preparing 250 concurrent users for battle.
The server is now under siege...

RoadRunner(4 worker)：

$ siege --no-parser -c 250 -t 30s http://127.0.0.1:8080/ > /dev/null
** SIEGE 4.0.4
** Preparing 250 concurrent users for battle.

如何加速Laravel应用

RoadRunner安装

RoadRunner已经提供了预编译的执行文件，下载对应平台的版本即可，配置文件可用RoadRunner提供的：Using RoadRunner.

Laravel配置

安装依赖：

composer require spiral/roadrunner zendframework/zend-diactoros symfony/psr-http-message-bridge

在Laravel项目创建一个psr-worker.php，代码修改来自tobias-kuendig：

<?php
require __DIR__ . "/vendor/autoload.php";
use SymfonyBridgePsrHttpMessageFactoryDiactorosFactory;
use SymfonyBridgePsrHttpMessageFactoryHttpFoundationFactory;
$relay = new SpiralGoridgeStreamRelay(STDIN, STDOUT);
$psr7 = new SpiralRoadRunnerPSR7Client(new SpiralRoadRunnerWorker($relay));
$app = require_once __DIR__ . '/bootstrap/app.php';
$kernel = $app->make(IlluminateContractsHttpKernel::class);
while ($req = $psr7->acceptRequest()) {
 try {
 $httpFoundationFactory = new HttpFoundationFactory();
 if (strpos($req->getHeaderLine("content-type"), "application/json") === 0) {
 $body = $req->getBody();
 $parsedBody = json_decode($body, true);
 $req = $req->withParsedBody($parsedBody);
 }
 $symfonyReq = $httpFoundationFactory->createRequest($req);
 $request = IlluminateHttpRequest::createFromBase($symfonyReq);
 $response = $kernel->handle($request);
 $psr7factory = new DiactorosFactory();
 $psr7response = $psr7factory->createResponse($response);
 $psr7->respond($psr7response);
 } catch (Throwable $e) {
 $psr7->getWorker()->error((string)$e);
 }
}

运行rr serve -v搞定。
