Python's method of implementing remote copy files based on SFTP and RSA keys _python

This example describes Python's method of implementing remote copy files based on SFTP and RSA keys. Share to everyone for your reference, specific as follows:

If you use the RSA secret key password-free login between the two servers, you can first find the corresponding directory of the RSA secret key (such as found/-name Id_rsa or locate Id_rsa).

The SCP functionality can then be implemented through the Paramiko module in Python:

def scp_by_key (Host_ip, Host_port, Remote_path, Local_path, username, pkey_path):
  try:
    Key=paramiko. Rsakey.from_private_key_file (pkey_path)
    t = Paramiko. Transport ((HOST_IP, Host_port))
    t.connect (Username=username, pkey=key)
    sftp = Paramiko. Sftpclient.from_transport (t)
    src = remote_path
    des = Local_path
    sftp.get (src,des)
    t.close ()
  Except Exception as E:
    print E

We can use this method in this way:

Copy Code code as follows:

Scp_by_key (' 192.168.0.33 ', '/xx/xxx/a.txt ', ' xx/xxx/b.txt ', ' Xiaomo ', '/home/xiaomo/.ssh/id_rsa ')

Isn't it cool to use it? But the premise is to have the RSA key ... If you need a password, simply swap the Pkey parameter for the password pass:

t = Paramiko. Transport ((HOST_IP, Host_port))
t.connect (username=username, password= ' xxx ')
