Python implementation of the remote file automatically packaged and download function example

In this article, the example of the Python implementation of the remote file automatically packaged and download function. Shared for your reference, as follows:

fig. a point of reference

In a Linux cluster operation, it is often necessary to execute Linux commands remotely in batches and synchronize files in both directions.

This example accomplishes this by using the idea of executing ssh, scp commands using the spawn() method.

II Code

import pexpect
import sys
ip="192.168.0.104"
user="root"
passwd="123456"
target_file="/data/"
child = ('/usr/bin/ssh', [user+'@'+ip])
fout = file('','w')
 = fout
try:
  ('password: ')
  (passwd)
  ('#')
  ('tar -czf /data/ '+target_file)
  ('#')
  print 
  ('exit')
  ()
except :
  print "expect EOF1"
except :
  print "expect TIMEOUT1"
child = ('/usr/bin/scp', [user+'@'+ip+':/data/','/home'])
fout = file('','a')
 = fout
try:
  ('(?i)password')
  (passwd)
  ()
except :
  print "expect EOF2"
except :
  print "expect TIMEOUT2"
