一款捕捉系统信号安全退出进程的任务

usage

$class = new class extends \HongXunPan\Signal\SignalJob {
//    protected $signals = [1];
    public function doJob()
    {
        sleep(3);
    }
};

$class->setStdLogStatus(true);
$class->loop();

输出

• 其他结束进程方法 kill -int pid 详细见 kill -l

extends

• 重写 protected $signals; 以实现接收指定信号
• 重写 function doJob() 实现常驻进程任务逻辑

more

实现守护进程的方法

• supervisor
• systemd
