1、安装swoole
wget https://github.com/swoole/swoole-src/archive/v1.9.1-stable.tar.gz
tar zxvf v1.9.1-stable.tar.gz
cd swoole-src-1.9.1-stable
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
2、配置php支持swoole
vi /usr/local/php/etc/php.ini
添加
extension=swoole.so
3、重启php-fpm
service php-fpm restart
在phpinfo页面可以看到关于swoole的选项，说明安装成功。

4.搭建Echo服务器
服务端 Server
创建一个Server.php文件并输入如下内容:

// Serverclass Server{ private $serv; public function __construct() { $this->serv = new swoole_server("0.0.0.0", 9501); $this->serv->set(array( 'worker_num' => 8, 'daemonize' => false, )); $this->serv->on('Start', array($this, 'onStart')); $this->serv->on('Connect', array($this, 'onConnect')); $this->serv->on('Receive', array($this, 'onReceive')); $this->serv->on('Close', array($this, 'onClose')); $this->serv->start(); } public function onStart( $serv ) { echo "Start\n"; } public function onConnect( $serv, $fd, $from_id ) { $serv->send( $fd, "Hello {$fd}!" ); } public function onReceive( swoole_server $serv, $fd, $from_id, $data ) { echo "Get Message From Client {$fd}:{$data}\n"; $serv->send($fd, $data); } public function onClose( $serv, $fd, $from_id ) { echo "Client {$fd} close connection\n"; }}// 启动服务器 Start the server$server = new Server();

客户端 Client
创建一个Client.php文件并输入如下内容：

<?phpclass Client{ private $client; public function __construct() { $this->client = new swoole_client(SWOOLE_SOCK_TCP); } public function connect() { if( !$this->client->connect("127.0.0.1", 9501 , 1) ) { echo "Error: {$this->client->errMsg}[{$this->client->errCode}]\n"; } fwrite(STDOUT, "请输入消息 Please input msg："); $msg = trim(fgets(STDIN)); $this->client->send( $msg ); $message = $this->client->recv(); echo "Get Message From Server:{$message}\n"; }}$client = new Client();$client->connect();

运行 Run it!
在Terminal下执行命令php Server.php即可启动服务器，在另一个Terminal下执行php Client.php，输入要发送的内容，即可发送消息到服务器，并收到来自服务器的消息。

websocket:

$server = new Swoole\WebSocket\Server("0.0.0.0", 9501);$server->on('open', function (Swoole\WebSocket\Server $server, $request) { echo "server: handshake success with fd{$request->fd}\n";});$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, "this is server");});$server->on('close', function ($ser, $fd) { echo "client {$fd} closed\n";});$server->start();
