1.根据php版本下载对应的swoole扩展版本进行编译安装，步骤安装官方手册进行安装即可

2.创建一个异步服务器程序Server，只能用于php-cli环境，以thinkphp5为例复制public目录下的入口文件index.php到cli目录cli.php里4.application目录下创建cli目录控制器TaskServer.php，代码如下：

    serv = new \Swoole\Server('0.0.0.0', 9504);        $this->serv->set(array(            'worker_num' => 4,//为CPU核数的1-4倍            'task_worker_num' => 4,            'max_request' => 10000,//最大请求            'daemonize' => 0,//1为守护进程            // 'log_file'=>"/www/log/service/cli/task.log"//日志文件        ));        $this->serv->on('Start',function($serv){            echo 'server start!';        });        $this->serv->on('Receive', function($serv, $fd, $from_id, $data) {            echo $data.PHP_EOL;            if (!$data)            {                echo "data error!";                $serv->send($fd,'fail');            }            else            {                $task_id = $serv->task($data);                $serv->send($fd,'ok');                echo "Dispath AsyncTask: id=$task_id".PHP_EOL;            }        });        $this->serv->on('Task', function ($serv, $task_id, $from_id, $data) {            echo "New AsyncTask[id=$task_id,from_id=$from_id]".PHP_EOL;                        //这里写入具体执行内容            $serv->finish("$data -> OK".PHP_EOL);        });        $this->serv->on('Finish', function ($serv, $task_id, $data) {            echo "AsyncTask[$task_id] Finish: $data\r\n\r\n";        });        $this->serv->start();    }

5.在linux环境中执行,php安装路径+项目路径

/usr/local/php7/bin/php /www/tp5/cli/cli.php Cli/Taskserver/start

如屏幕输出则创建成功6.编写api控制器index.php同步client客户端

$client = new \swoole_client(SWOOLE_SOCK_TCP);        if (!$client->connect('0.0.0.0', 9504, 0.5))        {            exit("connect failed. Error: {$client->errCode}\n");        }        $client->send("hello world\n");        echo $client->recv();        $client->close();

执行index.php,在linux屏幕可看到执行结果
