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... Lifting the server siege... Transactions:                   2032 hits Availability:                  97.83 % Elapsed time:                  29.19 secs Data transferred:               4.51 MB Response time:                  2.64 secs Transaction rate:              69.61 trans/sec Throughput:                     0.15 MB/sec Concurrency:                  183.50 Successful transactions:        2032 Failed transactions:              45 Longest transaction:           27.34 Shortest transaction:           0.

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. The server is now under siege... Lifting the server siege...

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。
