git clone https://gitee.com/swoole/swoole.git通过phpize（扩展php扩展模块，建立php外挂模块）：
cd swooleyour/phpize/path./configure --with-php-config=your/php/path/bin/php-configmake && make install可以看到swoole.so的位置
/opt/soft/php/lib/php/extensions/no-debug-non-zts-20170718/配置php.ini
extension=swoole.sophp -m命令，可以看到php的扩展模块检测swoole安装成功并且php支持swoole
cd your/swoole/path/examples/serverphp echo.php（如果进程被阻塞，则说明成功）netstat -anp | grep 9501（查看swoole开启的端口号）学习swoole需要去翻阅文档， swoole文档
tcp服务端（tcp_server.php）
//创建Server对象，监听 127.0.0.1:9501端口 $serv = new swoole_server("127.0.0.1", 9501); $serv->set([ 'worker_num' => 4, // worker进程数，cpu 1-4倍 'max_request' => 100, ]); /** * 监听连接进入事件 * $fd 客户端连接服务端的唯一标识 * $reactor_id 线程id */ $serv->on('connect', function ($serv, $fd, $reactor_id) { echo "Client: {$fd} - {$reactor_id} - Connect.\n"; }); //监听数据接收事件 $serv->on('receive', function ($serv, $fd, $reactor_id, $data) { $serv->send($fd, "Server: ".$data); }); //监听连接关闭事件 $serv->on('close', function ($serv, $fd) { echo "Client: Close.\n"; }); //启动服务器 $serv->start();
tcp客户端（tcp_client.php）
// 创建tcp客户端 $client = new swoole_client(SWOOLE_SOCK_TCP); // 连接tcp服务端 if (!$client->connect("127.0.0.1", 9501)) { echo '连接失败'; exit; } // php cli fwrite(STDOUT, '请输入：'); $msg = trim(fgets(STDIN)); // 发送消息给tcp服务端 if (!$client->send($msg)) { echo '发送消息失败'; exit; } // 接收 $result = $client->recv(); echo $result;
$server->on('Request', function ($req, $resp) { echo "hello world"; });
class A { static function test($req, $resp) { echo "hello world"; } } $server->on('Request', 'A::Test'); $server->on('Request', array('A', 'Test'));
function my_onRequest($req, $resp) { echo "hello world"; } $server->on('Request', 'my_onRequest');
class A { function test($req, $resp) { echo "hello world"; } } $object = new A(); $server->on('Request', array($object, 'test'));
小技巧：查看开启的worker进程：
ps aft | grep tcp_server.php
// 监听所有地址和9501端口 $http = new swoole_http_server('0.0.0.0', 9501); // 动静分离配置 $http->set([ // 开启静态请求 'enable_static_handler' => true, // 静态资源目录 'document_root' => '/opt/app/code1/', ]); $http->on('request', function ($request, $response) { // 获取get请求的参数 $param = json_encode($request->get); // 设置cookie $response->cookie('name', 'ronaldo', time() + 1800); // 输出到页面 $response->end("Hello Swoole - {$param}
"); }); // 开启http服务 $http->start();
websocket服务端（websocket_server.php）
// 监听所有地址和9502端口 $server = new swoole_websocket_server('0.0.0.0', 9502); // 动静分离配置 $server->set([ // 开启静态请求 'enable_static_handler' => true, // 静态资源目录 'document_root' => '/opt/app/swoole/websocket', ]); $server->on('open', function ($server, $request) { echo "server：handshake success with fd - {$request->fd}\n"; }); $server->on('message', function ($server, $frame) { echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n"; $server->push($frame->fd, "this is server"); }); $server->on('close', function ($server, $fd) { echo "client - {$fd} - close\n"; }); $server->start();
websocket客户端 （websockt_client.html）
// 创建websocket实例 var websocketURL = "ws://www.rona1do.top:9502"; var websocket = new WebSocket(websocketURL); // 实例化对象的onopen属性 websocket.onopen = function (ev) { websocket.send("hello-websocket"); console.log("connect-swoole-success"); } // 实例化对象的onmessage属性，接收服务端返回的数据 websocket.onmessage = function (ev) { console.log("websockect-server-return-data：" + ev.data); } // close websocket.onclose = function (ev) { console.log("close"); }
class WebSocket { const HOST = '0.0.0.0'; const PORT = 9502; private $ws = null; function __construct() { $this->ws = new swoole_websocket_server(self::HOST, self::PORT); $this->ws->on('open', [$this, 'onOpen']); $this->ws->on('message', [$this, 'onMessage']); $this->ws->on('close', [$this, 'onClose']); $this->ws->start(); } // 监听websocket连接事件 function onOpen($server, $request) { echo "server: handshake success with fd{$request->fd}\n"; } // 监听websocket消息接收事件 function onMessage($server, $frame) { echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n"; $server->push($frame->fd, "this is server"); } // 监听客户端关闭事件 function onClose($server, $fd) { echo "Client：{$fd} closes\n"; } }
onTask：在task_worker进程内被调用。worker进程可以使用swoole_server_task函数向task_worker进程投递新的任务。当前的Task进程在调用onTask回调函数时会将进程状态切换为忙碌，这时将不再接收新的Task，当onTask函数返回时会将进程状态切换为空闲然后继续接收新的Task。
onFinish：当worker进程投递的任务在task_worker中完成时，task进程会通过swoole_server->finish()方法将任务处理的结果发送给worker进程。
class Websocket { const HOST = '0.0.0.0'; const PORT = 9502; private $ws = null; public function __construct() { $this->ws = new swoole_websocket_server(self::HOST, self::PORT); $this->ws->set([ 'worker_num' => 2, 'task_worker_num' => 2, // 要想使用task必须要指明 ]); $this->ws->on('open', [$this, 'onOpen']); $this->ws->on('message', [$this, 'onMessage']); $this->ws->on('task', [$this, 'onTask']); $this->ws->on('finish', [$this, 'onFinish']); $this->ws->on('close', [$this, 'onClose']); $this->ws->start(); } public function onOpen($server, $request) { echo "server：handshake success with fd：{$request->fd}\n"; } public function onMessage($server, $frame) { echo "receive from {$frame->fd}:{$frame->data}\n"; // 需要投递的任务数据 $data = [ 'fd' => $frame->fd, 'msg' => 'task', ]; $server->task($data); $server->push($frame->fd, 'this is server'); } // 处理投递的任务方法，非阻塞 public function onTask($server, $task_id, $worker_id, $data) { print_r($data); // 模拟大量数据的操作 sleep(10); return "task_finish"; } // 投递任务处理完毕调用的方法 public function onFinish($server, $task_id, $data) { echo "task_id:{$task_id}\n"; echo "task finish success:{$data}\n"; } public function onClose($server, $fd) { echo "Client：close"; } }
