前言
衆所周知，Web 應用中，每次 HTTP 請求都需要經過 PHP-FPM，由它來處理 PHP 腳本。這一點在很大程度上降低了 QPS，如果使用 Swoole 擴展開啓一個 HTTP 服務來代替 PHP-FPM（同時一般情況下使用 Nginx 作爲反向代理服務器），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);
自定義配置文件 swoole.php 覆蓋默認配置
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 加載此文件
$app->configure('swoole');
使用
php artisan sumen start | restart | stop | reload | status
默認監聽 127.0.0.1 8080 端口，開啓 4 個 worker 進程
注意無法 reload 的文件 @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 常駐內存的特性，Lumen 中 Mysql、Redis 的連接需要做心跳檢測，每隔一段時間 ping 一次。做法如下：
// bootstrap/app.php
$app->singleton('heartBeat', function() {
// 在此寫心跳檢測的代碼
});
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;
}
}
