Yii2-Swoole 快速入门

Yii2-Swoole 快速入门

让你的 Yii2 应用性能提升 10-100 倍！本教程将教你如何在 yii2-app-basic 中快速集成 yii2-swoole。

为什么使用 yii2-swoole？

• ⚡ 比 PHP-FPM 快 10-100 倍
• 🔄 数据库和 Redis 连接池自动管理
• 🚀 协程并发处理请求
• 💻 代码几乎不需要修改

系统要求

• PHP >= 8.1
• Swoole >= 6.0
• Yii2 >= 2.0

安装 Swoole

pecl install swoole

在 php.ini 中添加：

extension=swoole.so

验证：

php --ri swoole

快速开始

1. 安装扩展

composer require dacheng-php/yii2-swoole

2. 创建配置文件

创建 config/swoole.php：

<?php

return [
    'bootstrap' => [
        [
            'class' => \Dacheng\Yii2\Swoole\Bootstrap::class,
            'componentId' => 'swooleHttpServer',
            'memoryLimit' => '2G',
        ],
    ],
    'components' => [
        'swooleHttpServer' => [
            'class' => \Dacheng\Yii2\Swoole\Server\HttpServer::class,
            'host' => '127.0.0.1',
            'port' => 9501,
            'documentRoot' => __DIR__ . '/../web',
            'settings' => [
                'max_coroutine' => 100000,
                'log_level' => SWOOLE_LOG_WARNING,
            ],
            'dispatcher' => new \Dacheng\Yii2\Swoole\Server\RequestDispatcher(
                __DIR__ . '/web.php'
            ),
        ],
    ],
];

3. 修改 Web 配置

编辑 config/web.php，在 return $config; 之前添加：

// 合并 Swoole 配置
$swooleConfig = require __DIR__ . '/swoole.php';
$config = \yii\helpers\ArrayHelper::merge($swooleConfig, $config);

4. 启动服务器

php yii swoole/start

访问 http://127.0.0.1:9501 即可！

停止服务器：

php yii swoole/stop
# 或按 Ctrl+C

进阶功能

数据库连接池

在 config/swoole.php 中添加：

'db' => [
    'class' => \Dacheng\Yii2\Swoole\Db\CoroutineDbConnection::class,
    'dsn' => 'mysql:host=127.0.0.1;dbname=your_database',
    'username' => 'root',
    'password' => '',
    'charset' => 'utf8mb4',
    'poolMaxActive' => 20,
    'poolWaitTimeout' => 5.0,
],

使用方式与标准 Yii2 完全相同，连接池自动管理。

Redis 连接池

composer require yiisoft/yii2-redis

在 config/swoole.php 中添加：

'redis' => [
    'class' => \Dacheng\Yii2\Swoole\Redis\CoroutineRedisConnection::class,
    'hostname' => '127.0.0.1',
    'port' => 6379,
    'poolMaxActive' => 20,
    'poolWaitTimeout' => 5.0,
],

'cache' => [
    'class' => \Dacheng\Yii2\Swoole\Cache\CoroutineRedisCache::class,
    'redis' => 'redis',
],

'session' => [
    'class' => \Dacheng\Yii2\Swoole\Session\CoroutineSession::class,
    'redis' => 'redis',
],

异步队列

composer require yiisoft/yii2-queue

配置：

'bootstrap' => [
    // ...
    'queue',
],
'components' => [
    'queue' => [
        'class' => \Dacheng\Yii2\Swoole\Queue\CoroutineRedisQueue::class,
        'redis' => 'redis',
        'channel' => 'queue',
        'concurrency' => 10,
    ],
],

创建任务 jobs/EmailJob.php：

<?php
namespace app\jobs;

class EmailJob extends \yii\base\BaseObject implements \yii\queue\JobInterface
{
    public $to;
    public $subject;
    
    public function execute($queue)
    {
        // 发送邮件
        \Yii::$app->mailer->compose()
            ->setTo($this->to)
            ->setSubject($this->subject)
            ->send();
    }
}

使用：

Yii::$app->queue->push(new EmailJob([
    'to' => 'user@example.com',
    'subject' => '测试',
]));

协程 HTTP 客户端

配置：

'httpClient' => [
    'class' => \Dacheng\Yii2\Swoole\HttpClient\CoroutineClient::class,
    'transport' => [
        'class' => \Dacheng\Yii2\Swoole\HttpClient\CoroutineTransport::class,
    ],
],

使用：

// 单个请求
$response = Yii::$app->httpClient->get('https://api.example.com/users')->send();

// 批量并发请求
$requests = [
    'users' => Yii::$app->httpClient->get('https://api.example.com/users'),
    'posts' => Yii::$app->httpClient->get('https://api.example.com/posts'),
];
$responses = Yii::$app->httpClient->batchSend($requests);

完整配置

config/swoole.php 示例：

<?php

return [
    'bootstrap' => [
        [
            'class' => \Dacheng\Yii2\Swoole\Bootstrap::class,
            'componentId' => 'swooleHttpServer',
        ],
        'queue',
    ],
    'components' => [
        'swooleHttpServer' => [
            'class' => \Dacheng\Yii2\Swoole\Server\HttpServer::class,
            'host' => '127.0.0.1',
            'port' => 9501,
            'documentRoot' => __DIR__ . '/../web',
            'dispatcher' => new \Dacheng\Yii2\Swoole\Server\RequestDispatcher(__DIR__ . '/web.php'),
        ],
        'db' => [
            'class' => \Dacheng\Yii2\Swoole\Db\CoroutineDbConnection::class,
            'dsn' => 'mysql:host=127.0.0.1;dbname=myapp',
            'username' => 'root',
            'password' => '',
            'poolMaxActive' => 20,
        ],
        'redis' => [
            'class' => \Dacheng\Yii2\Swoole\Redis\CoroutineRedisConnection::class,
            'hostname' => '127.0.0.1',
            'poolMaxActive' => 20,
        ],
        'cache' => [
            'class' => \Dacheng\Yii2\Swoole\Cache\CoroutineRedisCache::class,
            'redis' => 'redis',
        ],
        'session' => [
            'class' => \Dacheng\Yii2\Swoole\Session\CoroutineSession::class,
            'redis' => 'redis',
        ],
        'queue' => [
            'class' => \Dacheng\Yii2\Swoole\Queue\CoroutineRedisQueue::class,
            'redis' => 'redis',
        ],
    ],
];

常见问题

代码修改后不生效？

重启服务器：Ctrl+C 停止后重新启动（Swoole 常驻内存）

无法启动？

• 检查 Swoole 是否安装：php --ri swoole
• 检查端口占用：lsof -i:9501

连接超时？

增加 poolMaxActive 和 poolWaitTimeout 参数

静态文件 404？

确认 documentRoot 指向正确的 web 目录

生产部署

Systemd 服务

创建 /etc/systemd/system/yii2-app.service：

[Unit]
Description=Yii2 Swoole
After=network.target

[Service]
Type=simple
User=www-data
WorkingDirectory=/var/www/my-app
ExecStart=/usr/bin/php /var/www/my-app/yii swoole/start
Restart=on-failure

[Install]
WantedBy=multi-user.target

启动：

sudo systemctl daemon-reload
sudo systemctl enable yii2-app
sudo systemctl start yii2-app

Nginx 反向代理

server {
    listen 80;
    server_name example.com;
    
    location / {
        proxy_pass http://127.0.0.1:9501;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

注意事项

• ⚠️ 避免使用全局变量（多请求共享）
• ⚠️ 使用协程安全组件（CoroutineSession、CoroutineUser）
• ⚠️ 代码修改需要重启服务器
