這篇文章主要介紹了關於使用RoadRunner 加速Laravel 應用，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下
RoadRunner是一個用Go語言實現的高性能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。
使用siege測試Laravel的Welcome頁面，250個並髮用戶，持續30秒，對比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... Transactions: 61417 hits Availability: 100.00 % Elapsed time: 29.26 secs Data transferred: 135.95 MB Response time: 0.12 secs Transaction rate: 2099.01 trans/sec Throughput: 4.65 MB/sec Concurrency: 249.06 Successful transactions: 61417 Failed transactions: 0 Longest transaction: 0.20 Shortest transaction: 0.05
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.
安裝依賴：
composer require spiral/roadrunner zendframework/zend-diactoros symfony/psr-http-message-bridge
在Laravel專案創建一個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__ . '/bootstrap/app.php';
$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);
}
}運行rr serve -v搞定。
