使用 Swoole 加速 Lumen 框架

前言

众所周知，Web应用中，每次HTTP请求都需要经过PHP-FPM，由它来处理PHP脚本。这一点在很大程度上降低了QPS，如果使用Swoole扩展开启一个HTTP服务来代替PHP-FPM（同时一般情况下使用Nginx作为反向代理服务器），则即可解决这一问题。

安装

composer require kimistar/lumen_swoole

配置

在bootstrap/app.php中注册service provider

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

自定义配置文件swoole.php 覆盖默认配置

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,
];

同时在bootstrap/app.php加载此文件

$app->configure('swoole');

使用

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

默认监听127.0.0.1 8080端口，开启4个worker进程

注意无法reload的文件 @https://wiki.swoole.com/wiki/page/p-server...

包括但不限于

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

注意

由于Swoole常驻内存的特性，Lumen中Mysql、Redis的连接需要做心跳检测，每隔一段时间ping一次。做法如下：

// bootstrap/app.php
$app->singleton('heartBeat', function() {
    // 在此写心跳检测的代码
});

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;
    }
}
