Paramiko

First, installation

PIP3 Install Paramiko

　　

Second, use

1,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= ' c1.salt.com ', port=22, username= ' Wupeiqi ', password= ' 123 ')   # Execute command stdin, stdout, stderr = Ssh.exec_command (' ls ') # get command result = Stdout.read ()   # Close Connection ssh.close ()

Look at the code:

1, ssh = Paramiko. sshclient ()

def __init__ (self):
    """
    Create a new sshclient.
    """
    Self._system_host_keys = Hostkeys ()
    Self._host_keys = Hostkeys ()
    Self._host_keys_filename = None
    Self._log_channel = None
    Self._policy = Rejectpolicy ()
    Self._transport = None
    Self._agent = None

2, SSH. Connect (Hostname= ' c1.salt.com ', port=22, username= ' Wupeiqi ', password= ' 123 ')

326    Self._transport = Transport (sock, Gss_kex=gss_kex, gss_deleg_creds=gss_deleg_creds)

#其实SSHClient内部就是定义了transport来链接的

ImportParamiko#Create transport Specify host address and PortTransport = Paramiko. Transport (('hostname', 22))#connecting hosts using transportTransport.connect (username='Wupeiqi', password='123')#Create SSHSSH =Paramiko. Sshclient ()#Assignment TransportSsh._transport =Transportstdin, stdout, stderr= Ssh.exec_command ('DF')PrintStdout.read () transport.close ( )

The sshclient encapsulates the transport

Using Public key Links

Import Paramiko  Private_key = Paramiko. Rsakey.from_private_key_file ('/home/auto/.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= ' c1.salt.com ', port=22, username= ' Wupeiqi ', Key=private_key)  # Execute command stdin, stdout, stderr = Ssh.exec_command (' df ') # get command result = Stdout.read ()  # Close Connection ssh.close ()

ImportParamiko#defining secret key LocationsPrivate_key = Paramiko. Rsakey.from_private_key_file ('/home/auto/.ssh/id_rsa')#Create TransportTransport = Paramiko. Transport (('hostname', 22))#use transport to specify the user name, specify the secret keyTransport.connect (username='Wupeiqi', pkey=Private_key)#ConnectionSSH =Paramiko. Sshclient ()#use to assign transport to a valueSsh._transport =Transport#Execute Commandstdin, stdout, stderr = Ssh.exec_command ('DF') Transport.close ()

The sshclient encapsulates the transport

　　

2,sftpclient

For connecting to a remote server and performing an upload download

Upload and download based on user name password:

ImportParamiko#Create a link using transportTransport = Paramiko. Transport (('hostname', 22)) Transport.connect (username='Wupeiqi', password='123')  #and pour the transport intosftp=Paramiko. Sftpclient.from_transport (transport)#uploading location.py to the server/tmp/test.pySftp.put ('/tmp/location.py','/tmp/test.py')#download Remove_path to local Local_pathSftp.get ('Remove_path','Local_path') Transport.close () upload and download based on public key keys:

3, summary through the above SSH and SFTP can be seen that Paramiko links are used by the transport to achieve
