PYTHON:paramikoリモート操作の使用方法

1.Paramiko is a python's modules for link remote server.The following two methods are about how to use Paramiko link remote servers
The first method

   
   
   
   

    
    
    
    
ssh = paramiko.SSHClient() 
    
    
    
    
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 
    
    
    
    
ssh.connect(" IP  ",22,"   ", "  ") 
   
   
   
   

The second line code useage allow connecting unknow hosts in know-hosts file in above.
 
2.Example,Next code show the function about login server and excute a command and print into client.

   
   
   
   

    
    
    
    
#!/usr/bin/python  
    
    
    
    
import paramiko 
    
    
    
    
  
    
    
    
    
ssh = paramiko.SSHClient() 
    
    
    
    
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 
    
    
    
    
ssh.connect(" IP  ",22,"   ", "  ") 
    
    
    
    
stdin, stdout, stderr = ssh.exec_command("    ") 
    
    
    
    
print stdout.readlines() 
    
    
    
    
ssh.close() 
   
   
   
   

The usual command:

df：        
uptime：          
cat：       
mv/cp/mkdir/rmdir:          
/sbin/service/ xxxservice start/stop/restart：  、  、     
netstat -ntl |grep 8080：  8080        
    nc -zv localhost ：            
find / -name XXX：     

...

So we nearly do nothing face to more servers if you use the python code
 
 
3.Realize download file 

   
   
   
   

    
    
    
    
#!/usr/bin/python  
    
    
    
    
import paramiko 
    
    
    
    
  
    
    
    
    
t = paramiko.Transport((“  ”,”  ”)) 
    
    
    
    
t.connect(username = “   ”, password = “  ”) 
    
    
    
    
sftp = paramiko.SFTPClient.from_transport(t) 
    
    
    
    
remotepath=’/var/log/system.log’ 
    
    
    
    
localpath=’/tmp/system.log’ 
    
    
    
    
sftp.get(remotepath, localpath) 
    
    
    
    
t.close() 
   
   
   
   

 
4.Realize upload file

   
   
   
   

    
    
    
    
#!/usr/bin/python  
    
    
    
    
import paramiko 
    
    
    
    
 
    
    
    
    
t = paramiko.Transport((“  ”,”  ”)) 
    
    
    
    
t.connect(username = “   ”, password = “  ”) 
    
    
    
    
sftp = paramiko.SFTPClient.from_transport(t) 
    
    
    
    
remotepath=’/var/log/system.log’ 
    
    
    
    
localpath=’/tmp/system.log’ 
    
    
    
    
sftp.put(localpath,remotepath) 
    
    
    
    
t.close()
