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;
}
}
