Paramiko

The paramiko module is used to connect to a remote server and perform related operations based on SSH. This module can be used to perform commands or file operations on remote servers. It is worth noting that fabric and ansible use paramiko for internal remote management.

1. Install paramiko

pip3 install paramiko

2. Use paramiko

Sshclient

Import paramiko # create an SSH object SSH = paramiko. sshclient () # Allow connection to host SSH that is not in the know_hosts file. set_missing_host_key_policy (paramiko. autoaddpolicy () # connect to the server ssh. connect (hostname = 'c1 .salt.com ', Port = 22, username = 'wupeiqi', password = '000000') # Run stdin, stdout, stderr = ssh.exe c_command ('LS') # obtain the command result = stdout. read () # Close the SSH connection. close ()

Connect to a remote host based on the user name and password

Import paramiko private_key = paramiko. rsakey. from_private_key_file ('/home/auto /. SSH/id_rsa ') # create an SSH object SSH = paramiko. sshclient () # Allow connection to host SSH that is not in the know_hosts file. set_missing_host_key_policy (paramiko. autoaddpolicy () # connect to the server ssh. connect (hostname = 'c1 .salt.com ', Port = 22, username = 'wupeiqi', key = private_key) # Run stdin, stdout, stderr = ssh.exe c_command ('df ') # obtain the command result = stdout. read () # Close the SSH connection. close ()

Connect to a remote host based on the public key

　Sftpclient

Import paramiko transport = paramiko. transport ('hostname', 22) transport. connect (username = 'wupeiqi ', password = '000000') SFTP = paramiko. sftpclient. from_transport (Transport) # Set location. upload py to the server/tmp/test. pysftp. put ('/tmp/location. py', '/tmp/test. PY ') # download remove_path to the local local_pathsftp.get ('remove _ path', 'local _ path') transport. close ()

Upload Based on user name and password

Import paramiko private_key = paramiko. rsakey. from_private_key_file ('/home/auto /. SSH/id_rsa ') Transport = paramiko. transport ('hostname', 22) transport. connect (username = 'wupeiqi ', pkey = private_key) SFTP = paramiko. sftpclient. from_transport (Transport) # Set location. upload py to the server/tmp/test. pysftp. put ('/tmp/location. py', '/tmp/test. PY ') # download remove_path to the local local_pathsftp.get ('remove _ path', 'local _ path') transport. close ()

Upload Based on the key
