This article is about how to use the Fabric module in python. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Basic one:

#! / usr/bin/env python

From fabric.api import *

Env.user='root'

Env.hosts= ['218.78.186.162]

Env.passwords= {'root@218.78.186.162:22':'XXX','root@125.208.12.56:22':'XXXX@0'}

@ runs_once # runs_once representative only executes once

Def local_task ():

Local ("hostname") # local local tasks will not be executed remotely by ssh

Def remote_task ():

With cd ("/ tmp/"):

Run ("hostname") # run remote command

@ task # task tag only go function can call remote_task function

Def go ():

Remote_task ()

test

[root@hostnfsd: / soft/python/pyauto/ Chapter 7 / fabric] $fab-f simple1_test.py remote_task # failed to call the remote_task function directly

Warning: Command (s) not found:

Remote_task

Available commands:

Go

[root@hostnfsd: / soft/python/pyauto/ Chapter 7 / fabric] $fab-f simple1_test.py local_task # if you fail to call the local function directly when it is identified by the task table, you can only call the local function directly when you meitask

Warning: Command (s) not found:

Local_task

Available commands:

Go

[root@hostnfsd: / soft/python/pyauto/ Chapter 7 / fabric] $fab-f simple1_test.py go calls the remote_task function through the go function

[218.78.186.162] Executing task 'go'

[218.78.186.162] run: hostname

[218.78.186.162] out: localhost.localdomain

[218.78.186.162] out:

[125.208.12.56] Executing task 'go'

[125.208.12.56] run: hostname

[125.208.12.56] out: host-192-168156

[125.208.12.56] out:

Done.

Disconnecting from 218.78.186.162... Done.

Disconnecting from 125.208.12.56... Done.

Sometimes we want to execute it directly with a script, which can be changed as follows

#! / usr/bin/env python

From fabric.api import *

Env.user='root'

Env.hosts= ['218.78.186.162]

Env.passwords= {'root@218.78.186.162:22':'ESBecs00','root@125.208.12.56:22':'eRaMUnA612@0'}

@ runs_once

Def local_task ():

Local ("hostname")

Def remote_task ():

With cd ("/ tmp/"):

Run ("hostname")

Def go ():

Execute (remote_task) # execute means it can be executed within the script

Execute (local_task)

Go ()

Just run it directly.

[root@hostnfsd: / soft/python/pyauto/ Chapter 7 / fabric] $python simple1_test.py

Foundation 2:

#! / usr/bin/env python

From fabric.api import *

Env.user='root'

Env.hosts= ['218.78.186.162]

Env.passwords= {'root@218.78.186.162:22':'XXX','root@125.208.12.56:22':'XXXX@0'}

@ runs_once

Def input_raw ():

Return prompt ("please input directory name:", default= "/ home")

Def worktask (dirname):

Run ("ls-l" + dirname)

@ task

Def go ():

Getdirname = input_raw ()

Worktask (getdirname)

Jumping machine:

#! / usr/bin/env python

From fabric.api import *

From fabric.context_managers import *

From fabric.contrib.console import confirm

Env.user='root'

Env.gateway='218.78.186.162'

Env.hosts= ['125.208.12.56']

Env.passwords= {'root@218.78.186.162:22':'XX','root@125.208.12.56:22':'XXXX@0'}

Lpackpath= "/ home/install/lnmp0.9.tar.gz"

Rpackpath= "/ tmp/install"

@ task

Def put_task ():

Run ("mkdir-p / tmp/install")

With settings (warn_only=True):

Result = put (lpackpath, rpackpath)

If result.failed and not confirm ("put file failed, Continue [Ygamma N]?"):

Abort ("Aborting file put task!")

@ task

Def run_task ():

With cd ("/ tmp/install"):

Run ("tar-zxvf lnmp0.9.tar.gz")

Run ("ls-l")

@ task

Def go ():

Put_task ()

Run_task ()

Sometimes we need to write these function templates into django, so we can package the function into a class

#! / usr/bin/env python

From fabric.api import *

Class Student (object):

Def _ init__ (self,user,ip):

Env.user=user

Env.hosts= [ip]

Env.password='XXX'

@ runs_once

Def local_task (self):

Local ("hostname")

Def remote_task (self):

Vhost=run ("df-h")

Return vhost

Def yunxing (user,ip):

Tom=Student (user,ip)

Print execute (tom.remote_task)

Yunxing ('root','218.78.186.162') # call this function directly and pass parameters
