配置文件的设置

大体思路:

  1,通过开始文件将用户配置信息的文件放置到环境变量中。

  2,在lib文件中的config文件中,从环境变量中获取到用户的配置,通过importlib模块导入用户配置文件,通过dir方法获取到文件內的配置信息加载到本Settings类中。

  3,默认配置方式同上。

import os

os.environ["USER_SETTINGS"] = "config.settings"

from lib.conf.config import settings

print(settings.USER)
print(settings.EMAIL)
./bin/start
"""
用户自定义配置
"""

USER = "root"
EMAIL = "chenrun@163.com"
./config/settings

 

默认配置信息

"""
全局配置文件
"""
import os
import importlib
from . import global_settings


class Settings(object):
    def __init__(self):
        # 找到默认配置
        for name in dir(global_settings):
            value = getattr(global_settings, name)
            setattr(self, name, value)

        # 找到自定义配置
        settings_module = os.environ.get("USER_SETTINGS")
        # 根据字符串导入模块
        if settings_module:
            m = importlib.import_module(settings_module)
            for name in dir(m):
                if name.isupper():
                    value = getattr(m, name)
                    setattr(self, name, value)


settings = Settings()
./lib/conf/config

 

执行流程的大体思路:

basic.py

class Basic(object):
    def process(self):
        return "123123123"

  

init.py文件

从配置文件中获取到所有需要采集的硬件信息,通过importlib导入,并执行每个类里的process方法。

import importlib
from lib.conf.config import settings


class PluginManager(object):
    def __init__(self, hostname=None):
        self.hostname = hostname
        self.plugin_dict = settings.PLUGINS_DICT

    def exec_plugin(self):
        """
        获取所有的插件,并执行获取插件的返回值
        :return:
        """
        response = {}
        for k, v in self.plugin_dict.items():
            # 'basic': "src.plugins.basic.Basic"
            prefix, class_module = v.rsplit(".", 1)
            m = importlib.import_module(prefix)
            cls = getattr(m, class_module)
            result = cls().process()
            response[k] = result

        return response

  

start.py文件

通过sys.path.append() 导入根目录,方便导入src中的模块

import os

os.environ["USER_SETTINGS"] = "config.settings"
import sys

BASEDIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(BASEDIR)

from src.plugins import PluginManager

if __name__ == '__main__':
    server_info = PluginManager().exec_plugin()
    print(server_info)

  

后续在init中执行分别定义不同的连接方式,agent,paramiko,saltstack。

src下创建client与script文件

client处理发送API,获取资产信息,获取ssh

import json

import requests

from src.plugins import PluginManager
from lib.conf.config import settings


class Base(object):
    def post_asset(self, server_info):
        requests.post(settings.API, json=server_info)


class Agent(Base):

    def execute(self):
        server_info = PluginManager().exec_plugin()
        self.post_asset(server_info)


class SSHSALT(Base):
    def get_host(self):
        # 获取未采集的主机列表
        response = requests.get(settings.API)
        result = json.loads(response.text)
        if not result["status"]:
            return
        return result["data"]

    def execute(self):
        host_list = self.get_host()
        for host in host_list:
            server_info = PluginManager(host).exec_plugin()
            self.post_asset(server_info)
./src/client

script.py文件对不同的模式进行判断返回obj对象

from . import client
from lib.conf.config import settings


def run():
    if settings.MODE == "AGENT":
        obj = client.Agent()
    else:
        obj = client.SSHSALT()

    obj.execute()
./src/script.py
