thinkphp5+GatewayWorker+Workerman

项目地址  ttps://www.workerman.net/workerman-chat

thinkphp5+GatewayWorker+Workerman聊天室，可以多人聊天，指定某个人进行聊天，还可以切换聊天房间
Windows版安装
a) 安装thinkphp5：

composer create-project topthink/think tp5  --prefer-dist

b) 进入tp5的目录，安装Windows版本的workerman：

composer require workerman/workerman-for-win

c)安装Windows版本的gateway：

composer require workerman/gateway-worker-for-win

然后在项目根目录 新增入口文件 start_register.php 、start_gateway.php 、start_businessworker.php三个入口文件

文件：start_register.php

<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','index/Sregister');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

文件：start_gateway.php

<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','index/Sgateway');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

文件：start_businessworker.php

<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','index/Sbusinessworker');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';

d): 由于PHP-CLI在windows系统无法实现多进程以及守护进程,所以只能把三个文件放到bat文件，然后双击启动

bat文件：start_for_win.bat

php start_register.php start_gateway.php start_businessworker.phppause

代码目录截图

启动程序

在项目的根目录下双击启动 start_for_win.bat

linux版安装

a) 安装thinkphp5：

b) 进入tp5的目录，安装linux版本的workerman：

composer require topthink/think-worker

c) 安装linux版本的gateway：

composer require workerman/gateway-worker-for-win
