Python 之 paramiko 模塊

paramiko模塊是用python語言寫的一個模塊，遵循SSH2協議，支持以加密和認證的方式，進行遠程服務器的連接

1.安裝

#paramiko模塊的安裝需要先安裝PyCrypto模塊

wget  https://pypi.python.org/packages/source/p/pycrypto/pycrypto-2.6.1.tar.gz

wget

cd pycrypto-2.6.1

python setup.py build

python setup.py install

https://pypi.python.org/packages/source/p/paramiko/paramiko-1.13.0.tar.gz

cd paramiko-1.13.0

python setup.py build

python setup.py install

yum安裝

yum -y  install python-crypto python-paramiko

測試

>>> import paramiko

>>> dir(paramiko)

例子1：ssh到多台主機，執行相同的命令。

#!/usr/bin/python

import paramiko

USER = 'root'

PASSWORD = '123456'

COMMAND = 'mkdir 888'

for line in open('/root/ip.txt'):

    IP = line

    paramiko.util.log_to_file('/root/zhu.log')

    s = paramiko.SSHClient()

    s.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    s.connect(hostname=IP,username=USER,password=PASSWORD)

    s.exec_command(COMMAND)

    s.close

###############

[root@zhu ~]# cat ip.txt

192.168.56.101

192.168.56.102

例子2：把指定的文件上傳到多台主機上。

#!/usr/bin/python

import paramiko

PORT = 22

USER = 'root'

PASSWORD = '123456'

REMORE_PATH = '/tmp/qianshan.txt'

LOCAL_PATH = '/root/1.txt'

for line in open('/root/ip.txt'):

    IP = line

    t = paramiko.Transport((IP,PORT))

    t.connect(username=USER,password=PASSWORD)

    s = paramiko.SFTPClient.from_transport(t)

    s.put(LOCAL_PATH,REMORE_PATH)

    t.close
