python之简单主机批量管理工具

 

转发注明出处:http://www.cnblogs.com/0zcl/p/6352278.html 

今天做了一个很简单的小项目，感受到了paramiko模块的强大，也深感自己Linux的功力不行~~

一、需求

二、简单需求分析及流程图

需求很少，我就简单地说下:
　　1. 主机分组可以配置文件实现(我用字典存数据的).
　　2. 登陆功能不做。选择分组后可查看组内对应主机的主机名和IP地址.
　　3. >>>cmd: df(输入命令则起多个线程(视组内有多少个主机而定)同时执行)
　　　 输出:
　　　 －－－－－－－－－－－－－h1－－－－－－－－－－－－
　　　 ……(命令返回的数据)
　　　 －－－－－－－－－－－－－h2－－－－－－－－－－－－
　　　 ……
　　　 >>>put  test.yy(本地文件)   filename (把本地的test.yy文件传到远程主机的/root目录下)
　　4.可写在配置文件中。包括远程主机的: 主机名 IP 用户名 密码 端口

三、目录结构及源代码

目录结构:

测试:

硬件限制，我只用连接一台虚拟机测试~

C:\Python34\python3.exe C:/Users/Administrator/PycharmProjects/laonanhai/host_manage/main.py
