Centos7在安装完php7.3的基础上安装swoole

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

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
