swoole熱更新

在不殺掉進程下進行熱更新

官網熱更新，這裏不作詳細說

https://wiki.swoole.com/wiki/page/46.html

代碼目錄結構

testS.php ----- 服務端

<?php
$server = new swoole_server("0.0.0.0", 9501);
$server->on('WorkerStart', function ($serv, $worker_id){
	// 熱更新
	echo "WorkerStart: {$worker_id}\n";
	require_once 'test.php';
});
$server->on('connect', function ($server, $fd){
    echo "connection open: {$fd}\n";
	$test = new Test();
	$test->getTime();
});
$server->on('receive', function ($server, $fd, $reactor_id, $data) {
    $server->send($fd, "Swoole: {$data}");
    $test = new Test();
    echo "send fd: {$fd}\n";
    echo $data . "\n";
	$test->getTime();
});
$server->on('close', function ($server, $fd) {
    echo "connection close: {$fd}\n";
});
$server->start();

testC.php ----- 客戶端

<?php
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);
$client->on("connect", function($cli) {
    $cli->send("hello world\n");
});
$client->on("receive", function($cli, $data){
    echo "received: {$data}\n";
    $cli->send(1);
    sleep(5);
    $cli->send(2);
});
$client->on("error", function($cli){
    echo "connect failed\n";
});
$client->on("close", function($cli){
    echo "connection close\n";
});
$client->connect("0.0.0.0", 9501, 0.5);

test.php -----   操做類

<?php
class Test
{
	/**
     * [__construct 初始化]
     */
    public function __construct()
    {
        date_default_timezone_set('Asia/Shanghai'); 
    }

    public function getTime()
    {
    	echo "test\n";
    }

}

運行代碼

服務端

php testS.php

控制檯輸出

send fd: 1

客戶端
php testC.php

熱更新

首先把test操做類的方法輸出改成

echo "test12\n";

而後理看進程 ps -auxf | grep php

把254下的worker進程重載

kill -USR1 254

重載後
