swoole自定义进程如何热重启

swoole 官方明确 swoole 自定义进程 addProcess 不支持热重启，但是换个思路可以实现

public function main(){
        $this->server = new Server("0.0.0.0",20000);

        $this->server->set([
            "worker_num"=>2,
            "daemonize"=>true,
            "reload_async"=>true,
        ]);
        $this->startProcess($this->server);
        foreach ($this->events as $event){
            $this->server->on($event,[$this,$event]);
        }
        $this->server->start();
    }

    public function startProcess(Server $server){
        $server->addProcess(new Process(function(Process $process){
            
            swoole_set_process_name("z:process");

            $run = true;
            require "./test.php";
            pcntl_signal(SIGUSR1,function ($signo){
                file_put_contents("/data/wwwroot/php-cli/process.log",time()." {$signo}\n",FILE_APPEND);
                require "./test.php";
            });
            
            while($run){
                pcntl_signal_dispatch();
                test();
            }

        }));
    }

// 通过外部发送 SIGUSR1 实现杀死自定义进程，然后swoole的manager 会重新拉起一个新的Process.. 并不会丢失原有的业务。。
