paramiko模块是用Python语言写的一个模块，遵循SSH2协议，支持以加密和认证的方式，进行远程服务器的连接
1.安装
#paramiko模块的安装需要先安装PyCrypto模块
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安装
yum -y install python-crypto python-paramiko
测试
>>> import paramiko
>>> dir(paramiko)

例子1：ssh到多台主机，执行相同的命令。
#!/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：把指定的文件上传到多台主机上。
#!/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
