这篇文章主要介绍了php中SWOOLE的热更新实现代码实例，热更新是比较常用的技术，有需要同学可以研究下
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=/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";
}
