paramiko是用python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。利用该模块，可以方便的进行ssh连接和sftp协议进行sftp文件传输以及远程命令执行。

通过安装包安装：

wget http://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.tar.gz

wget http://www.lag.net/paramiko/download/paramiko-1.7.7.1.tar.gz

tar -zxvf pycrypto-2.6.tar.gz

cd pycrypto-2.6/

python setup.py build && python setup.py install

wget http://www.lag.net/paramiko/download/paramiko-1.7.7.1.tar.gz

tar xvzf paramiko-1.7.7.1.tar.gz

cd paramiko-1.7.7.1/

python setup.py build && python setup.py install

yum安装，简单省事：

yum install python-paramiko -y

简单使用：从远程服务器拷贝文件：


#coding=utf-8
import paramiko, os
def remote_scp(type, host_ip, remote_path, local_path, username, password):
 ssh_port = 22
 try:
  conn = paramiko.Transport((host_ip, ssh_port))
  conn.connect(username=username, password=password)
  sftp = paramiko.SFTPClient.from_transport(conn)
  if type == 'remoteRead':
   if not local_path:
    fileName = os.path.split(remote_path)
    local_path = os.path.join('/tmp', fileName[1])
   sftp.get(remote_path, local_path)
  if type == "remoteWrite":
   sftp.put(local_path, remote_path)
  conn.close()
  return True
 except Exception:
  return False
