Python Paramiko Module installation and use of detailed _python

First, the preface

Common solutions will require the necessary configuration of the remote server, if the remote server only one or two good said, if there are N, but also need to configure each platform, or need to use code to do the above, the above approach is not very convenient. The use of Paramiko can solve the above problem, compared to the previous method, it only needs to install the appropriate software (Python and Pycrypto), the remote server does not have the configuration requirements, for connecting multiple servers, the complex connection operation is particularly helpful. The following article on the detailed introduction of Python Paramiko module installation and use, learn together. 、

Second, the installation

There are two prerequisites for installing Paramiko, Python and another module called Pycrypto.

Standard Python modules are typically installed and run only in the root directory of the module:

Python setup.py build
python setup.py install

Note: check to see if GCC is installed before installation (yum-y install GCC)

2.1 Pycrypto Installation

wget http://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.tar.gz
tar-zxvf pycrypto-2.6.tar.gz
CD pycrypto-2.6/
python setup.py build && python setup.py install

Test:

Python>> Import Crypto

(Compile times Error: Error:command ' gcc ' failed with exit status 1; This is due to the lack of Python-dev packages, yum-y install python-devel)

2.2 Paramiko Installation

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
Crypto error: ' Module ' object has no at Tribute ' Have_decl_mpz_powm_sec '

Test:

Python>> Import Paramiko
(Crypto error: ' Module ' object has no attribute ' have_decl_mpz_powm_sec '

Find/usr/lib/python2.7/site-packages/crypto/util/number.py

Put

If _fastmath is not-None and not _fastmath. Have_decl_mpz_powm_sec:

Commented on

#if _fastmath is not None and not _fastmath. Have_decl_mpz_powm_sec:

Third, the use

3.1 Execute remote command

#!/usr/bin/python
import Paramiko
 
ssh = Paramiko. Sshclient ()
ssh.set_missing_host_key_policy (Paramiko. Autoaddpolicy ())
ssh.connect ("An IP address", 22, "username", "password")
stdin, stdout, stderr = Ssh.exec_command ("Your Command")
print stdout.readlines ()
ssh.close ()

3.2 Uploading files to remote

#!/usr/bin/python
Import Paramiko
 
t = Paramiko. Transport ("An IP Address,")
t.connect (username = "username", password = "password")
sftp = Paramiko. Sftpclient.from_transport (t)
remotepath= '/tmp/test.txt '
localpath= '/tmp/test.txt ' Sftp.put
( Localpath,remotepath)
T.close ()

3.3 Downloading files from remote

#!/usr/bin/python
Import Paramiko
 
t = Paramiko. Transport ("An IP Address,")
t.connect (username = "username", password = "password")
sftp = Paramiko. Sftpclient.from_transport (t)
remotepath= '/tmp/test.txt '
localpath= '/tmp/test.txt ' Sftp.get
( RemotePath, LocalPath)
t.close ()
