源码下载和安装

yum install autoconf

wget https://github.com/swoole/swoole-src/archive/v4.4.12.tar.gz

tar zxvf v4.4.12.tar.gz

cd swoole-src-4.4.12/

phpize 

./configure --with-php-config=/usr/local/php/bin/php-config 

make 

sudo make install

sudo vim /usr/local/php/lib/php.ini //添加 extension=swoole

php -m //查看扩展是否安装成功

测试

server.php

<?php

//创建Server对象，监听 127.0.0.1:9501端口

$serv = new Swoole\Server("127.0.0.1", 9501); 

//监听连接进入事件

$serv->on('Connect', function ($serv, $fd) {  

    echo "Client: Connect.\n";

});

//监听数据接收事件

$serv->on('Receive', function ($serv, $fd, $from_id, $data) {

    $serv->send($fd, "Server: ".$data);

});

//监听连接关闭事件

$serv->on('Close', function ($serv, $fd) {

    echo "Client: Close.\n";

});

//启动服务器

$serv->start(); 

运行源码

php server.php

此时服务端处于阻塞状态

telnet模拟客户端连接

yum -y install telnet

连接服务端

telnet 127.0.0.1 9501

此时服务端会提示Client: Connect.

客户端会提示：

Trying 127.0.0.1...

Connected to 127.0.0.1.

Escape character is '^]'.

此时在客户端打印hello，服务端会返回hello

# telnet 127.0.0.1 9501

Trying 127.0.0.1...

Connected to 127.0.0.1.

Escape character is '^]'.

hello

Server: hello

断开连接

ctrl+] 用于退出当前连接。此时服务端会打印Client: Close.

再输入q退出telnet
