saltstack主机管理项目：计主机管理项目命令分发器（三）

一、开发目标命令格式如下：

 

二、目录结构

三、代码注解

01、salt.py 只是一个入口，没干什么事情

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#!/usr/bin/env python # -*- coding:utf-8 -*- # Author:luoahong     import os, sys   if __name__ == "__main__":     os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Stark.settings")     BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))     # print(BASE_DIR)     sys.path.append(BASE_DIR)     from Arya.action_list import actions     from Arya.backends.utils import ArgvManagement       obj = ArgvManagement(sys.argv)

 

02、action_list.py 路由分发器

?

1 2 3 4 5 6 7 8 9

#!/usr/bin/env python # -*- coding:utf-8 -*- # Author:luoahong   from Arya.plugins import cmd,state actions = {     'cmd': cmd.CMD,     'state':state.State }

03、 建了一个目录backends目录下 创建一个utils.py

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

#!/usr/bin/env python # -*- coding:utf-8 -*- # Author:luoahong   from Arya import action_list import django django.setup()   from Stark import settings from Arya import models class ArgvManagement(object):     '''     接收用户指令并分配到相应模块     '''     def __init__(self,argvs):         self.argvs = argvs         self.argv_parse()       def help_msg(self):         print("Available modules:")         for registered_module in action_list.actions:             print("  %s" % registered_module)         exit()     def argv_parse(self):         print(self.argvs)         if len(self.argvs) <2:             self.help_msg()         module_name = self.argvs[1]         if '.' in module_name:             mod_name,mod_method = module_name.split('.')             module_instance  = action_list.actions.get(mod_name)             if module_instance:#matched                module_instance(self.argvs,models,settings)           else:             exit("invalid module name argument")

 

04、plugins 建立一个目录创建两个类

1、 cmd.py 

?

1 2 3

from Arya.backends.base_module import BaseSaltModule class CMD(BaseSaltModule):     print('in cmd module ')

2、state.py

?

1 2 3 4 5

from Arya.plugins import cmd,state   from Arya.backends.base_module import BaseSaltModule class State(BaseSaltModule):     print('in state module ')

四、命令行运行截图
