SECURECRT (SSH remote connection software)

Software Introduction:

What the fabric website says about it:

Fabric is a Python (2.5-2.7) library and command-line tool for streamlining the use of SSH for application deployment or S Ystems administration tasks.

It provides a basic suite of operations for executing local or remote shell commands (normally or via sudo ) and uploading /downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution .

President

Fabric is an SSH command-line tool based on Python (2.5 to 2.7) that simplifies application deployment and system administration for SSH, and provides a system-based operational component that enables local or remote shell commands, including command execution, file upload, download, and full execution log output.

Experimental process:

First, the software download

[Email protected] ~]# Easy_install fabric #首先你得确保你安装了python-setuptools

Second, check whether the installation is successful

You can see that there is no error stating that the module was successfully imported.

Third, the official website Introduction Test Example

1. Sample Map of Fabric website

If you don't know how to set it, you can look at my article below.

Iv. execute commands remotely, and get output on this machine

1. Create a script file

2. Invoking the Local_task task function through the FAB command

1. script File Writing

[Email protected] ~]# vim fuchao02.py

#!/usr/bin/env python

From FABRIC.API Import *

Env.user= "Root"

env.hosts=[' 192.168.0.44 ']

Env.passwd= "123456"

@runs_once

Def input_raw ():

return prompt ("Please input directory name:", default= "/root")

def worktask (dirname):

Run ("Ls-l" +dirname)

@task

def go ():

Getdirname = Input_raw ()

Worktask (Getdirname)

2. Script execution

Seven, gateway mode file upload and execution

1, the script file writing
