Python使用Paramiko模块实现远程文件拷贝

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。

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 install python-paramiko -y
