本文介绍了如何使用swoole进行热重启操作，详细解析了swoole_reload_server.php、reload.sh和reload_page.php的流程。通过修改reload_page.php中的代码并执行.sh脚本，观察到服务器状态的变化，从而实现swoole服务的热重启。

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
<?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";
}

操作流程如下
