php中Swoole的热更新实现代码实例

使用swoole_http_server替代php-fpm后，由于php长驻内存,修改了代码不能实时调试，需要去手动去重启服务,很是不方便，决定使用inotify来监控文件状态的改变，来给swoole发送reload信号,来实现swoole的热更新。

如何安装inotify就不写了，安装之后可以建立一个脚本文件，如php_reload.sh:

#!/bin/sh # src 需要监控的地址 src=https://www.jb51.net/home/server/Project/test/app/ /usr/bin/inotifywait -rmq -e create,modify,delete $src | while read event do /home/server/Project/test/bin/httpserver reload done

linux shell 写swoole重启脚本

代码如下

#!/bin/sh kill `lsof -t -i:9501` sleep 2 php /data/web/mircoweb/wwwroot/Public/swoole.php sleep 1 netstat -ntlp

如果不支持lsof命令 那就yum install lsof安装下吧

swoole服务平滑重启

1. reload.sh脚本

echo "loading..." pid="pidof live_name" echo $pid kill -USR1 $pid echo "loading success"

2. linux中执行

sh  reload.sh
代码用的原来只是自己加了一些操作流程

swoole_reload_server.php

<?php class 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,             'max_request' => 10000,             'dispatch_mode' => 2,             'debug_mode'=> 1,         ));         $this->serv->on('Start', array($this, 'onStart'));         $this->serv->on('WorkerStart', array($this, 'onWorkerStart'));         $this->serv->on('Connect', array($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";         cli_set_process_title("reload_master");     }     public function onWorkerStart( $serv , $worker_id) {         require_once "reload_page.php";         Test();     }     public function onConnect( $serv, $fd, $from_id ) {         echo "Client {$fd} connect\n";       }     public function onReceive( swoole_server $serv, $fd, $from_id, $data ) {         echo "Get Message From Client {$fd}:{$data}\n";     }     public function onClose( $serv, $fd, $from_id ) {         echo "Client {$fd} close connection\n";     } } new Server();

reload.sh

echo "Reloading..." cmd=$(pidof reload_master)   kill -USR1 "$cmd" echo "Reloaded"

reload_page.php 

<?php /**  * If you change this function and want  * swoole_server to use the new function,  * just run 'reload.sh' to send a restart  * signal to swoole_server.  */ function Test() {   echo "This is not a php file\n"; }
