安装
# 下载swoole git clone # 进入目录 cd ./swoole-src #切换版本 git checkout v4.2.2 # 编译安装 phpize clean #[php] Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environme #出现以上报错解决办法 apt-get install autoconf make clean phpize ./configure --enable-openssl --enable-sockets --enable-mysqlnd make make install # 找到php.ini路径 php -i |grep php.ini # 编辑php.ini vi /etc/php/7.0/cli/php.ini # 在文件中加入extension=swoole.so # 查看是否已经安装成功php -m# 如果找到 swoole 说明安装成功
Web 服务器
创建 swoole_http_server.php 写入：
$http = new swoole_http_server("0.0.0.0", 9501);
$http->on('request', function ($request, $response) {
var_dump($request->get, $request->post);
$response->header("Content-Type", "text/html; charset=utf-8");
$response->end("<h1>Hello Swoole. #".rand(1000, 9999)."</h1>");
});
$http->start();启动
php swoole_http_server.php
开启进程守护(后台模式)
$this->server->set([ 'daemonize' => 1, ]);
关闭
先找到进程号
netstat -apn | grep 9503
杀死这个进程
kill -9 14323 # 14323 是进程号

PHP Websocket 实现简易聊天系统.md
WebSocket是一个持久化的协议，举个简单的例子，http1.0的生命周期是以request作为界定的，也就是一个request，一个response，对于http来说，本次client与server的会话到此结束；而在http1.1中，稍微有所改进，即添加了keep-alive，也就是在一个http连接中可以进行多个request请求和多个response接受操作。然而在实时通信中，并没有多大的作用，http只能由client发起请求，server才能返回信息，即server不能主动向client推送信息，无法满足实时通信的要求。而WebSocket可以进行持久化连接，即client只需进行一次握手，成功后即可持续进行数据通信，值得关注的是WebSocket实现client与server之间全双工通信，即server端有数据更新时可以主动推送给client端。
