source FileName
做用:在当前bash

中的命令。 用于从新执行刚修改的初始化文档,如 .bash_profile
和 .profile
等等
注:该命令一般用命令“.

如:source /etc/profile
与 . /etc/profile
是等效的react

phpize
是用来扩展php
模块的,经过phpize
能够创建php
的外挂模块,解决没有configure
问题github
/usr/local/php/bin/phpize # 在须要执行的目录执行这行代码便可 ./configure --with-php-config=/usr/local/php/bin/php-config
make make install
最后能够在PHP
的扩展目录中看见swoole.so
扩展文件web
在php.ini
文件中添加:extension=swoole.so
查看是否添加成功:php -m

在swoole/examples/server
下执行php echo.php
查看是否执行端口:9501

)Swoole官网文档:建立TCP服务器 | 建立UDP服务器json
//建立Server对象,监听 127.0.0.1:9501端口 $serv = new swoole_server("127.0.0.1", 9501); //swoole_server->set函数用于设置swoole_server运行时的各项参数 $serv->set([ 'worker_num' => 6 , // worker进程数,cpu 1-4倍 'max_request' => 10000, ]); /** * 监听链接进入事件 * $fd 客户端链接的惟一标示 * $reactor_id 线程id */ $serv->on('connect', function ($serv, $fd, $reactor_id) { echo "Client: {$reactor_id} - {$fd}-Connect.\n"; }); /** * 监听数据接收事件 * $reactor_id = $from_id */ $serv->on('receive', function ($serv, $fd, $reactor_id, $data) { $serv->send($fd, "Server: {$reactor_id} - {$fd}".$data); }); //监听链接关闭事件 $serv->on('close', function ($serv, $fd) { echo "Client: Close.\n"; }); //启动服务器 $serv->start();
测试tcp
服务器方法:
netstat -anp | grep 9501
telnet
方式登陆远程主机:telnet 127.0.0.1 9501
tcp
客户端脚本 查看当前worker
进程数:ps -aft | grep tcp_server.php
Tips:为了保证程序执行的完整性,当修改tcp
服务器脚本后最好设置平滑重启worker
进程
平滑重启worker进程

WebSocket
协议是基于TCP
的一种新的网络协议。它实现了浏览器与服务器全双工(full-duplex
)通讯--容许服务器主动发送信息给客户端
为何须要WebSocket
HTTP
的通讯只能由客户端发起WebSocket特色
TCP
协议之上ws
wss
1. 面向过程:
procedure_ws_server.php
$server = new swoole_websocket_server("0.0.0.0", 9912); //配置静态文件根目录,可选 $server->set( [ 'enable_static_handler' => true, 'document_root' => "/home/wwwroot/www.lingyuan88.com/public/swoole/data", ] ); //监听websocket链接打开事件 $server->on('open', 'onOpen'); function onOpen($server, $request) { print_r($request->fd); } // 监听ws消息事件 $server->on('message', function (swoole_websocket_server $server, $frame) { echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n"; $server->push($frame->fd, "singwa-push-secesss"); }); $server->on('close', function ($ser, $fd) { echo "client {$fd} closed\n"; }); $server->start();
2. WebSocket服务优化,基础类库面向对象:
object_ws_server.php
class Ws { CONST HOST = "0.0.0.0"; CONST PORT = 9912; public $ws = null; public function __construct() { $this->ws = new swoole_websocket_server(self::HOST, self::PORT); //配置静态文件根目录,可选 $this->ws->set( [ 'enable_static_handler' => true, 'document_root' => "/home/wwwroot/www.lingyuan88.com/public/swoole/data", ] ); $this->ws->on("open", [$this, 'onOpen']); $this->ws->on("message", [$this, 'onMessage']); $this->ws->on("close", [$this, 'onClose']); $this->ws->start(); } /** * 监听ws链接事件 * @param $ws * @param $request */ public function onOpen($ws, $request) { print_r($request->fd); } /** * 监听ws消息事件 * @param $ws * @param $frame */ public function onMessage($ws, $frame) { echo "ser-push-message:{$frame->data}\n"; $ws->push($frame->fd, "server-push:".date("Y-m-d H:i:s")); } /** * close * @param $ws * @param $fd */ public function onClose($ws, $fd) { echo "clientid:{$fd}\n"; } } $obj = new Ws();
ws_client.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> </head> <body> <h1>singwa-swoole-ws测试</h1> <script> var wsUrl = "ws://120.77.206.215:9912"; var websocket = new WebSocket(wsUrl); //实例对象的onopen属性 websocket.onopen = function(evt) { websocket.send("hello-sinwa"); console.log("conected-swoole-success"); } // 实例化 onmessage websocket.onmessage = function(evt) { console.log("ws-server-return-data:" + evt.data); } //onclose websocket.onclose = function(evt) { console.log("close"); } //onerror websocket.onerror = function(evt, e) { console.log("error:" + evt.data); } </script> </body> </html>
1. 经过WebSocket
静态文件目录测试
2. 经过HTTP
服务测试
使用场景
注意:
继续往下执行
,不会等待任务执行完后再继续向下执行class Ws { CONST HOST = "0.0.0.0"; CONST PORT = 9912; public $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, ] ); //注册Server的事件回调函数 $this->ws->on("open", [$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(); } /** * 监听ws链接事件 * @param $ws * @param $request */ public function onOpen($ws, $request) { var_dump($request->fd); } /** * 监听ws消息事件 * @param $ws * @param $frame */ public function onMessage($ws, $frame) { echo "ser-push-message:{$frame->data}\n"; // todo 10s $data = [ 'task' => 1, 'fd' => $frame->fd, ]; //投递异步任务 //注意:程序会继续往下执行,不会等待任务执行完后再继续向下执行 $ws->task($data); //客户端会立刻收到如下信息 $ws->push($frame->fd, "server-push:".date("Y-m-d H:i:s")); } /** * @param $serv * @param $taskId * @param $workerId * @param $data * @return string */ public function onTask($serv, $taskId, $workerId, $data) { print_r($data); // 耗时场景 10s sleep(10); return "on task finish"; // 告诉worker,并返回给onFinish的$data } /** * @param $serv * @param $taskId * @param $data */ public function onFinish($serv, $taskId, $data) { echo "taskId:{$taskId}\n"; echo "finish-data-sucess:{$data}\n"; } /** * close * @param $ws * @param $fd */ public function onClose($ws, $fd) { echo "clientid:{$fd}\n"; } } $obj = new Ws();
务必理解
) 关注的是消息通知
机制;
同步: 调用发出以后不会当即返回
,但一旦返回,则返回最终结果;异步:调用发出以后,被调用方
当即返回消息
,但返回的并不是最终结果。被调用者经过状态、通知机制等来通知调用者,或经过回调函数来处理结果;
关注的是调用者等待被调用者返回调用结果时的状态。
阻塞:调用结果返回以前,调用者会被挂起
,调用者只有在获得返回结果以后才能继续。非阻塞:调用者在结果返回以前,不会被挂起;

swoole使用redis的前置条件
redis
服务hiredis
库swoole
须要加入 -enable-async-redis
编译安装hiredis
使用Redis
客户端,须要安装hiredis
库,下载hiredis
源码后,执行
make -j sudo make install sudo ldconfig
启用异步Redis客户端
编译swoole
时,在configure
指令中加入--enable-async-redis
[root@izwz93ee3z8wdxsujiec2oz swoole]# ./configure --with-php-config=/usr/local/php/bin/php-config --enable-async-redis make clean make -j sudo make install
查看PHP
的swoole
扩展:php -m
