如何用RoadRunner加速Laravel應用

RoadRunner是一個用Go語言實現的高效能PSR-7伺服器，你沒看錯，是Go語言實現的。

RoadRunner先用Go實作了高效能的伺服器，然後透過goridge IPC把請求轉送給多個PHP CLI Worker，Worker會把請求重新封裝成PSR-7 Request交給框架處理。

娛樂測試

使用siege測試Laravel的Welcome頁面，250個並髮用戶，持續30秒，比較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

如何加速Laravel應用程式

RoadRunner安裝

RoadRunner已經提供了預先編譯的執行文件，下載對應平台的版本即可，設定檔可用RoadRunner提供的：Using RoadRunner.

Laravel配置

安裝依賴：

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

在Laravel專案建立一個psr-worker.php，程式碼修改來自tobias-kuendig：

<?php
require __DIR__ . "/vendor/autoload.php";
use Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory;
use Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory;
$relay = new Spiral\Goridge\StreamRelay(STDIN, STDOUT);
$psr7 = new Spiral\RoadRunner\PSR7Client(new Spiral\RoadRunner\Worker($relay));
$app = require_once __DIR__ . &#39;/bootstrap/app.php&#39;;
$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
while ($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);
        $request = Illuminate\Http\Request::createFromBase($symfonyReq);
        $response = $kernel->handle($request);
        $psr7factory = new DiactorosFactory();
        $psr7response = $psr7factory->createResponse($response);
        $psr7->respond($psr7response);
    } catch (\Throwable $e) {
        $psr7->getWorker()->error((string)$e);
    }
}

#執行rr serve -v搞定。
