Python简单主机批量管理工具

一、程序介绍

需求：

简单主机批量管理工具

需求:
 1.主机分组
 2.主机信息使用配置文件
 3.可批量执行命令、发送文件，结果实时返回
 4.主机用户名密码、端口可以不同
 5.执行远程命令使用paramiko模块

程序结构:

Host_manage/ #程序目录
├── bin #启动程序目录
│   └── start.py  #启动程序文件
├── conf  #配置目录
│   ├── __pycache__
│   │   └── settings.cpython-36.pyc
│   └── settings.py   #配置文件
├── core  #主程序目录
│   ├── __pycache__
│   │   └── src.cpython-36.pyc
│   └── src.py  #主程序
└── log 

二、流程图

三、代码

bin/start.py

 1 #!/usr/bin/env python
 2 #_*_coding:utf-8_*_

 4 import os
 5 import sys
 6 
 7 BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
 8 sys.path.append(BASE_DIR)
 9 print(BASE_DIR)
10 
11 from core import src
12 
13 if __name__ == ‘__main__‘:
14     src.run()
