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.so
php -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) {

});class A
{
static function test($req, $resp)

{
function test($req, $resp)
{

}
}
$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
$response->end("<h1>Hello Swoole - {$param}</h1>");
});
// 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

}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);

// 监听客户端关闭事件

}
}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。
