使用 Swoole 加速 Lumen 框架

框架

前言

眾所周知，Web應用中，每次HTTP請求都需要經過PHP-FPM，由它來處理PHP指令碼。這一點在很大程度上降低了QPS，如果使用Swoole擴充套件開啟一個HTTP服務來代替PHP-FPM（同時一般情況下使用Nginx作為反向代理伺服器），則即可解決這一問題。

安裝

composer require kimistar/lumen_swoole

配置

在bootstrap/app.php中註冊service provider

$app->register(Star\LumenSwoole\SwooleServiceProvider::class);

自定義配置檔案swoole.php 覆蓋預設配置

return [
   'host' => '127.0.0.1',
    'port' => 8080,
    'daemonize' => 0,
    'dispatch_mode' => 3,
    'worker_num' => 4,
    'max_request' => 5000,
    'log_file' => storage_path('logs/swoole.log'),
    'log_level' => 5,
    'pid_file' => storage_path('logs/swoole.pid'),
    'open_tcp_nodelay' => 1,
    'heart_beat_internal' => 300,
];

同時在bootstrap/app.php載入此檔案

$app->configure('swoole');

使用

php artisan sumen start | restart | stop | reload | status

預設監聽127.0.0.1 8080埠，開啟4個worker程式

注意無法reload的檔案 @https://wiki.swoole.com/wiki/page/p-server...

包括但不限於

  • bootstrap/app.php
  • app/Providers/*
  • config/*
  • app/Console/*

注意

由於Swoole常駐記憶體的特性，Lumen中Mysql、Redis的連線需要做心跳檢測，每隔一段時間ping一次。做法如下：

// bootstrap/app.php
$app->singleton('heartBeat', function() {
    // 在此寫心跳檢測的程式碼
});

配置Nginx

server {
    listen 80;
    server_name your.domain.com;

    location / {
        try_files /_not_exists @swoole;
    }

    location @swoole {
        proxy_http_version 1.1;
        #proxy_set_header Connection "keep-alive";
        proxy_set_header Host $host;
        proxy_set_header SERVER_PORT $server_port;
        proxy_set_header REMOTE_ADDR $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        # proxy_set_header HTTPS "on";

        proxy_pass http://127.0.0.1:8080;
    }
}
