停止某个机房所有机器上包的脚本 pack_idc_stop.py
一、初衷：
鉴于公司的进程包package都是冗余多点部署的，一般一个idc机房有多台机器部署同一个package。当机房网络出问题的时候，我们不得不查到本机房部署了哪些package,并在包发布系统中一个个查询并停掉。这样就很费时费力。
利用包发布系统提供的一些接口stop.do等，做了个停掉某个机房所有package的脚本。只需之前把所有包名，机房名写入配置文件pack_idc.json，执行脚本时通过带不同的配置文件做为参数，即可实现批量停掉包的目的。
二、原理：
因为包发布系统的接口返回都是json，所以本脚本主要就是用post/get方法调用接口，处理json，利用dict、list做一些匹配、过滤、组合的操作。
主要用到:
python的urllib模块的urlopen(）: http://www.cnblogs.com/langdashu/p/4963053.html
python解析json : http://www.cnblogs.com/langdashu/p/4963098.html
python判断内网IP : http://www.cnblogs.com/langdashu/p/4962657.html
python的字典、列表的应用
python脚本传参数、处理文件、json注释方法
三、实例：
pack_idc.json pack_idc_start.py pack_idc_stop.py
执行方法 python pack_idc_stop.py pack_idc.json
1、配置文件pack_idc.json
{
"pack_name":["yc_agent","duang_agent"],
"idc_name":"北京鲁谷BGP-01",
"comment":"这是注释"
}
pack_name可以是任意多个，idc_name必须唯一。若pack_name有一个不存在本idc上会自动过滤掉。
通过事先配置好不同的json文件，当需要停某个机房的package的时候，只需执行脚本带上相应的配置文件即可。
2、脚本pack_idc_stop.py
