Login to SSH using Python's Paramiko module

Paramiko is a module written in the Python language that follows the SSH2 protocol and supports the connection of remote servers in a way that is encrypted and authenticated.
Python's Paramiko module makes it easy to implement SSH logins and execute commands.

1. Paramiko Module Installation 1.1 Install Pycrypto Library

The home page of the Paramiko library is here: Https://pypi.python.org/pypi/paramiko
The installation method of the Paramiko library is super simple.

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

2. Simply use 2.1 to execute a remote command

 #!/usr/bin/python import paramiko ssh = Paramiko.set_missing_host_key_policy (Paramiko .connect ( "One IP address", 22," user name ", " password ") stdin, stdout, stderr = Ssh.exec_command ( "your command") print stdout .readlines () ssh.close ()     

2.2 Uploading files to remote

    #!/usr/bin/python    import paramiko    t = paramiko.Transport(("某IP地址",22))    t.connect(username = "用户名", password = "口令") sftp = paramiko.SFTPClient.from_transport(t) remotepath=‘/tmp/test.txt‘ localpath=‘/tmp/test.txt‘ sftp.put(localpath,remotepath) t.close()

2.3 Uploading files to remote

    #!/usr/bin/python    import paramiko    t = paramiko.Transport(("某IP地址",22))    t.connect(username = "用户名", password = "口令") sftp = paramiko.SFTPClient.from_transport(t) remotepath=‘/tmp/test.txt‘ localpath=‘/tmp/test.txt‘ sftp.get(remotepath, localpath) t.close()

3. Advanced usage

It is often necessary to manage multiple servers or virtual machines, which can be done in a batch manner.
