Paramiko Introduction

Paramiko is a python-based SSH2 Remote installation connection that supports authentication and secret key methods. Can implement remote command execution, file transfer, intermediate SSH proxy and other functions.

Paramiko API Installation: Pip install Paramiko

Paramiko Login to remote host based on username and password

Sshclient

Used to connect to a remote server and execute basic commands

Import Paramiko   # SSH object created ssh = Paramiko. Sshclient () # allows connections to host Ssh.set_missing_host_key_policy (Paramiko) that are not in the Know_hosts file. Autoaddpolicy ()) # Connection Server Ssh.connect (hostname= ' 172.16.2.100 ', port=22, username= ' root ', password= ' 123345 ')   # Execute command stdin, stdout, stderr = Ssh.exec_command (' ls ') # get command result = Stdout.read ()   # Close Connection ssh.close ()

The specific implementation script is as follows:

#!/usr/bin/env pythonimport paramikotransport = Paramiko. Transport ((' 172.20.2.234 ')) Transport.connect (username= ' root ', password= ' 000000 ') ssh = Paramiko. Sshclient () Ssh._transport = Transportstdin,stdout,stderr = Ssh.exec_command (' uname-a ') print (Stdout.read ()) Transport.close ()

Paramiko Login to remote host based on secret key

Import Paramiko  Private_key = Paramiko. Rsakey.from_private_key_file ('/root/.ssh/id_rsa ')  # create ssh object ssh = Paramiko. Sshclient () # allows connections to host Ssh.set_missing_host_key_policy (Paramiko) that are not in the Know_hosts file. Autoaddpolicy ()) # Connection Server Ssh.connect (hostname= ' 172.16.2.234 ', port=22, username= ' root ', Key=private_key)  # Execute command stdin, stdout, stderr = Ssh.exec_command (' df ') # get command result = Stdout.read ()  # Close Connection ssh.close ()

The specific implementation script is as follows:

[email protected] paramiko]# cat para_key.py #!/usr/bin/env python import paramikoprivate_key = Paramiko. Rsakey.from_private_key_file ('/root/.ssh/id_rsa ') transport = Paramiko. Transport ((' 172.20.2.234 ')) Transport.connect (username= ' root ', pkey=private_key) ssh = Paramiko. Sshclient () Ssh._transport = Transportstdin,stdout,stderr =  ssh.exec_command (' Df-ht ') print (Stdout.read ()) Transport.close ()

Paramiko for uploading and downloading remote files

Sftpclient

For connecting to a remote server and performing an upload download

Upload and download based on user name password:

Import Paramiko  transport = Paramiko. Transport (' 172.16.2.234 ', ()) Transport.connect (username= ' root ', password= ' 123345 ')  sftp = Paramiko. Sftpclient.from_transport (transport) # upload location.py to Server/tmp/test.pysftp.put ('/data/local/location.py ', '/data/ remote/test.py ') # download Remove_path to local local_pathsftp.get (' Remove_path ', ' Local_path ')  transport.close ()

The specific implementation code is as follows:

#!/usr/bin/env Pythonimport paramikousername = ' root ' password = ' 000000 ' hostname = ' 172.20.2.234 ' port = 22try:    t = par Amiko. Transport ((hostname,port))    t.connect (username=username,password=password)    sftp = Paramiko. Sftpclient.from_transport (t)    sftp.put ('/data/local/localfile ', '/data/remote/remotefile ')    sftp.get ('/ Data/remote/remotefile1 ', '/data/local/localfile1 ')    sftp.mkdir ('/data/aaa ', 0755)    sftp.rmdir ('/data/aaa ') )    sftp.rename ('/data/remote/test.sh ', '/data/remote/testfile.sh ')    print (Sftp.stat ('/data/remote/ testfile.sh ')    print (Sftp.listdir ('/data/remote ')) except Exception as E:    print (e)
