图文详解python之简单主机批量管理工具

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~

上传前没有from_windows.py文件,上传后就有了!
