dubbo-php-framework控制台provider_admin解析

结合上一篇的简介，这篇开始分析服务的启动过程，从上篇文章可以知道，启动服务是通过provider_admin去控制的，对应到代码就是bin目录，bin目录下有app_admin.php和restartall.sh，而restartall.sh的实现，就是遍历机器上所有的provider进程名，然后调用app_admin.php完成重启，故我们就分析app_admin的过程。

<?php
define("BIN_DIR", __DIR__);//常量定义，取PHP系统常量，也就是当前bin目录。
define('MYROOT',BIN_DIR."/..");//常量定义，当前bin目录的上级目录

//加载commom

require_once($fsofCommonPath.DIRECTORY_SEPARATOR.'BootStrap.php');

//常量定义，定义swoole里面master和manager的进程文件命名格式
if(!defined("MASTER_PID_FILE_FORMAT")) define("MASTER_PID_FILE_FORMAT",'.master.pid');
