使用python的fabric库在远程主机上执行命令

先安装PIP

[[email protected] ~]# yum install python-pip -y

 

 

再用PIP的方式安装这个版本的fabric

[[email protected] ~]# pip install fabric==1.14.0

 

编写python脚本

[[email protected] py]# cat fabric1.py
#!/usr/bin/env python
from fabric.api import *
from fabric.context_managers import *
from fabric.contrib.console import confirm

env.user='root'
env.hosts=['192.168.156.75']
env.password='yourpassword'

@task
@runs_once
def tar_task():
    with lcd("/75shell/py"):
        local("tar -czf fabric1.tar.gz fabric1.py")
@task
def put_task():
    run("mkdir -p /fab/test")
    with cd("/fab/test"):
        with settings(warn_only=True):
            result = put("/75shell/py/fabric1.tar.gz", "/fab/test/fabric1.tar.gz")
        if result.failed and not confirm("put file failed, Continue[Y/N]?"):
            abort("Aborting file put task!")

@task
def check_task():
    with settings(warn_only=True):
        lmd5=local("md5sum /75shell/py/fabric1.tar.gz",capture=True).split(' ')[0]
        rmd5=run("md5sum /fab/test/fabric1.tar.gz").split(' ')[0]
    if lmd5==rmd5:
        print "OK"
    else:
        print "ERROR"

@task
def go():
    tar_task()
    put_task()
    check_task()

 

执行:

[[email protected] py]# fab -f fabric1.py go

 

在v75上面验证:
