python小技巧

由于公司的服务器只能通过publickey登录，本地只有一个dsa文件，登录服务器时必须通过此文件，下面具体给出示例；

1，打开ssh客户端，然后执行命令

import paramiko

def ssh2(ip,username,passwd,cmd):
    try:
        paramiko.util.log_to_file('paramiko.log')
        ssh  = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        keyFile = r'E:\workfile\mylib\id_dsa_2048'
        ssh.connect(ip,22,username,passwd,timeout=5,key_filename=keyFile)
        stdout,stdin,stderr = ssh.exec_command(cmd)
        print stdout._read(1024)
    except Exception,e :
        print "Error.",e 


if __name__ == "__main__":
    cmd = "mkdir -p ./aa/bb/cc"
    ssh2('192.168.0.3','root','*********','ls')

2，打开sftp客户端，然后上传文件

#!/usr/bin/env python

import socket
import paramiko
import os

username='root'
hostname='192.168.0.3'
port = 22

sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((hostname, port))

t=paramiko.Transport(sock)

t.start_client()

key=t.get_remote_server_key()

privatekeyfile = os.path.expanduser(r'E:\workfile\mylib\id_dsa_2048')

mykey = paramiko.DSSKey.from_private_key_file(privatekeyfile,password='********')

t.auth_publickey(username,mykey)

sftp=paramiko.SFTPClient.from_transport(t)

sftp.put(r"E:\workfile\test\crm.rar","/root/crm.rar")

sftp.close()

t.close()

3，综合使用

import paramiko

def ssh2(ip,username,passwd,cmd):
    try:
        paramiko.util.log_to_file('paramiko.log')
        ssh  = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        keyFile = r'E:\workfile\mylib\id_dsa_2048'
        ssh.connect(ip,22,username,passwd,timeout=5,key_filename=keyFile)
        stdout,stdin,stderr = ssh.exec_command(cmd)
        print stdout._read(1024)

        sftp = ssh.open_sftp()
        sftp.put(r"E:\workfile\test\crm.rar","/root/crm.rar")

        ssh.close()

    except Exception,e :
        print "Error.",e 


if __name__ == "__main__":
    cmd = "mkdir -p ./aa/bb/cc"
    ssh2('192.168.0.3','root','********','ls')
