1，安装

yum -y install epel-release
yum -y install fabric

2,指定密码的使用：
fab -p 123456 -H 192.168.10.10 -f f1.py w

#cat f1.py

#!/usr/bin/env python
from fabric.api import run
def w():
    run('w')

确定：当指定的密码不正确的时候，会一直让你尝试输入密码

3，通过定义的密码文件来执行fab命令

[root@localhost mnt]# vim f2.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from fabric.api import *
env.hosts = ['192.168.10.104','192.168.10.105','192.168.10.101']
env.port = '22'
env.user = 'root'
env.password = '123456'

def a():
    with cd('/tmp'):
        run('touch a{1..10}')
        run('ls /tmp')
def b():
    run('uptime')
@task
def go():
    a()
    b()

[root@localhost mnt]# fab -f f2.py go
