Python Paramiko module

Paramiko Module

1. Introduction:

Paramiko is a module for remote control, which can be used to command or file the remote server, it is worth saying that the fabric and ansible internal remote management is the use of Paramiko to reality.

2. Download and install

PIP3 Install Paramiko #在python3中

# in the Python2 PIP3 Install PYCRYPTOPIP3 install Paramiko Note: If the following error        occurred while installing pycrypto2.0.1 ' GCC ' failed with exit status 1 ... May be missing python-dev Install package causes GCC to be installed if GCC is not installed

in the Python2

3. Use

Sshclient

Used to connect to a remote server and execute basic commands

Connect based on user name password:

ImportParamiko#To create an SSH objectSSH =Paramiko. Sshclient ()#allow connections to hosts that are not in the Know_hosts fileSsh.set_missing_host_key_policy (Paramiko. Autoaddpolicy ())#connecting to a serverSsh.connect (hostname='120.92.84.249', Port=22, Username='Root', password='XXX')#Execute Commandstdin, stdout, stderr = Ssh.exec_command ('DF')#Get command Resultsresult =Stdout.read ()Print(Result.decode ('Utf-8'))#Close ConnectionSsh.close ()

ImportParamikotransport= Paramiko. Transport (('120.92.84.249', 22)) Transport.connect (username='Root', password='XXX') SSH=Paramiko. Sshclient () Ssh._transport=Transportstdin, stdout, stderr= Ssh.exec_command ('DF') Res=Stdout.read ()Print(Res.decode ('Utf-8') ) Transport.close ()

sshclient Package Transport

Connection based on public key:

Client file name: I D_rsa

The server must have a file name: Authorized_keys (when using Ssh-keygen, must make a authorized_keys, can be made with Ssh-copy-id)

ImportParamikoprivate_key= Paramiko. Rsakey.from_private_key_file ('/tmp/id_rsa')#To create an SSH objectSSH =Paramiko. Sshclient ()#allow connections to hosts that are not in the Know_hosts fileSsh.set_missing_host_key_policy (Paramiko. Autoaddpolicy ())#connecting to a serverSsh.connect (hostname='120.92.84.249', Port=22, Username='Root', pkey=Private_key)#Execute Commandstdin, stdout, stderr = Ssh.exec_command ('DF')#Get command Resultsresult =Stdout.read ()Print(Result.decode ('Utf-8'))#Close ConnectionSsh.close ()

Connect based on a private key string

Sftpclient

For connecting to a remote server and performing an upload download

Upload and download based on user name password

ImportParamiko Transport= Paramiko. Transport (('120.92.84.249', 22)) Transport.connect (username='Root', password='XXX') sftp=Paramiko. Sftpclient.from_transport (transport)#uploading location.py to the server/tmp/test.pySftp.put ('/tmp/id_rsa','/etc/test.rsa')#download Remove_path to local Local_pathSftp.get ('Remove_path','Local_path') Transport.close ()

Demo Seven jobs

Title: Simple Mainframe Bulk management tool

Demand:

1. Host grouping
2. Host information configuration file with Configparser parsing
3. Can execute the command in batch, send the file, the result returns in real time, the execution format is as follows
   1. Batch_run-h h1,h2,h3-g web_clusters,db_servers-cmd "Df-h"
   2. Batch_scp-h h1,h2,h3-g web_clusters,db_servers-action put-local test.py-remote/tmp/
4. Host user name password, port can be different
5. Execute remote command using Paramiko module
6. Bulk commands need to use multiprocessing concurrency
