使用swoole_http_server替代php-fpm後，由於php長駐記憶體,修改了程式碼不能實時除錯，需要去手動去重啟服務,很是不方便，決定使用inotify來監控檔案狀態的改變，來給swoole傳送reload訊號,來實現swoole的熱更新。

如何安裝inotify就不寫了http://www.cppcns.com，安裝之http://www.cppcns.com後可以建立一個指令碼檔案，如php_reload.sh:

#!/bin/sh
# src 需要監控的地址
src=/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 寫swoole重啟指令碼

程式碼如下

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

如果不支援lsof命令 那就yum install lsof安裝下吧

swoole服務平滑重啟

1. reload.sh指令碼

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

2. linux中執行

sh  reload.sh
程式碼用的原來只是自己加了一些操作流程

swoole_reload_server.php

<?php
clawww.cppcns.comss 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','onWorkerStart'));
        $this->serv->on('Connect','onConnect'));
        $this->serv->on('Receive','onReceive'));
        $this->serv->on('Close','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 $serv,$from_id,$data ) {
        echo "Get Message From Client {$fd}:{$data}\n";
    }
    public function onClose( $serv,$from_id ) {

www.cppcns.com
 
60;       echo "Client {$fd} close connection\n";
    }
}
new Server();

reload.sh

echo "Reloading..."
cmd=$(pidof rehttp://www.cppcns.comload_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";
}
