安装swoole
pecl install swoole修改PHP配置文件php.ini加入
extension=swoole.so有可能不需要人工去加，安装时自动加入进来了，
查看swoole扩展是否安装好
/usr/local/php/bin/php -m
配制列表里面如果有swoole的话，恭喜你安装并配置swoole成功。
在index.php同级目录下面新新建ws.php文件，文件内容以下
<?php class Ws {CONST HOST = "0.0.0.0";CONST PORT = 9501;public $ws = null;public function __construct() {$this->ws = new swoole_websocket_server(self::HOST, self::PORT);$this->ws->set(['worker_num' => 4,//打开的进程数'daemonize'=>0,//1守护进程，在后台一直运行 ]);//websocket继承于http_service，所以拥有http_service服务器的所有函数//http_service函数，$this->ws->on("start", [$this, 'onStart']); $this->ws->on("workerstart", [$this, 'onWorkerStart']);//此事件在Worker进程/Task进程启动时发生。$this->ws->on("request", [$this, 'onRequest']);$this->ws->on("task", [$this, 'onTask']);$this->ws->on("finish", [$this, 'onFinish']);//websocket函数$this->ws->on("open", [$this, 'onOpen']);$this->ws->on("message", [$this, 'onMessage']);$this->ws->on("close", [$this, 'onClose']);$this->ws->start();//开启 }/*** @param $server*/public function onStart($server) {swoole_set_process_name("websocket");//修改进程名称，非必要 }/*** @param $server* @param $worker_id*/public function onWorkerStart($server, $worker_id) {//swoole是cli运行，执行地址path会无法正确找到，所以把base.php里面定义的常量提出来，设置为假，//注意：记住把源代码base.php里面的define('IS_CLI',false)代码去掉（常量不能重复定义）,在index.php里面加入代码：define('IS_CLI', PHP_SAPI == 'cli' ? true : false);define('IS_CLI',false);// //当进程运行时，把框架代码加载进来// 定义应用目录define('APP_PATH', __DIR__ .

因为tp里面的全局变量会在进程的内存里面不变，会导致执行地址path不更新，需要修改源代码
修改框架源代码thinkphp/library/think/Request.php，两处地方，如下2图：
上面是服务端websocket代码，下面是客户端JS
<script>
var wsServer = 'ws://193.112.27.236:9501/index/login/a?cc=1'; //websocket服务端地址,记住ws://不能去掉
var websocket = new WebSocket(wsServer);
websocket.onopen = function (evt) {console.log("Connected to WebSocket server.");websocket.send(1111);//发送数据给服务器
};//服务端关闭时调用
websocket.onclose = function (evt) {console.log("Disconnected");
};//服务端向客户端发送消息时调用
websocket.onmessage = function (evt) {console.log('Retrieved data from server: ' + evt.data);
};//服务端报错时调用
websocket.onerror = function (evt, e) {console.log('Error occured: ' + evt.data);
};
</script>
注意：linux上面运行开启服务时
php ws.php以上命令可能会有问题，因为cli模式下运行的php 可能跟你项目运行的php版本跟配置文件不一样
可以使用以下命令来保证准确：
查看是否启动成功
修改代码之后，需要杀死进程，重新启动
