python使用paramiko模块实现ssh远程登陆上传文件并执行

程序执行时需要读取两个文件command.txt和ipandpass.txt。格式如下:

代码如下:


command.txt:
ThreadNum:1
port:22
local_dir:hello_mkdir
remote_dir:hello_mkdir
alter_auth:chmod 755 hello_mkdir
exec_program:./hello_mkdir

ipandpass.txt:
ip username password

程序中的队列操作是修改的别的程序,写的确实不错。
该程序亦正亦邪,如果拿去做坏事,我先声明与我无关,我只是分享我的代码罢了。
希望有兴趣的同志们来讨论技术应用。
这其中用到了paramiko,队列,多线程,后续也会写一些这三个方面的东西。欢迎批评指正。
其实这个程序有些地方还有待优化。

代码如下:


#function:upload files through ssh protocal and excute the files
#lib:paramiko
#MyThread:init a thread to run the function
#ThreadPol:init a thread pool
#uploadAndExecu:upload file and excute
#readConf:read config file
#-*- coding = utf-8 -*-
