两台机器：10.1.6.186、10.1.6.159。fabric部署在10.1.6.186上面
1 执行和1相同的任务，不过排除掉10.1.6.159这台机器
1 #!/usr/bin/python 2 from fabric.api import * 3 from fabric.context_managers import * 4 5 env.hosts=[‘10.1.6.186‘,‘10.1.6.159‘] 6 env.password=‘xxxxxx‘ 7 env.exclude_hosts=[‘10.1.6.159‘] 8 9 def task1(): 10 with cd(‘/home/guol‘): 11 run(‘ls -l‘) fab task1
2 执行和2相同任务，再增加一个task2，并且把taskN伪装成meta任务执行
#!/usr/bin/python
from fabric.api import *
from fabric.colors import *
from fabric.context_managers import *
env.hosts=[‘10.1.6.186‘,‘10.1.6.159‘]
env.password=‘xxxxxx‘
env.exclude_hosts=[‘10.1.6.159‘]
def task1():
with cd(‘/home/guol‘):
run(‘ls -l‘)
def task2():
print(green("I‘m fabric"))
def deploy():
execute(task1)
execute(task2)
##执行
[email protected]:/tmp# fab deploy
3 不同的机器执行不同的task
#!/usr/bin/python
from fabric.api import *
from fabric.colors import *
from fabric.context_managers import *
env.roledefs={‘web1‘:[‘10.1.6.186‘],‘web2‘:[‘10.1.6.159‘]}
env.password=‘xxxxxx‘
@roles(‘web1‘)
def task1():
with cd(‘/home/guol‘):
run(‘ls -l‘)
@roles(‘web2‘)
def task2():
print(green("I‘m fabric"))
def deploy():
execute(task1)
execute(task2)
##执行
[email protected]:/tmp# fab deploy
4 把159的/home/guol/159-remote拉取到186的 /home/guol/目录下
#!/usr/bin/python
from fabric.api import *
from fabric.colors import *
from fabric.context_managers import *
env.hosts=[‘10.1.6.159‘]
env.password=‘xxxxxx‘
def task1():
print(green("I‘m 186 /home/guol/"))
local(‘ls -l /home/guol‘)
def task2():
print(green("I‘m get 159‘s 159-remote file to 186"))
get(‘/home/guol/159-remote‘,‘/home/guol‘)
print(yellow("I‘m 186 /home/guol/"))
local(‘ls -l /home/guol‘)
def deploy():
execute(task1)
execute(task2)
##执行
[email protected]:/tmp# fab deploy

Disconnecting from 10.1.6.159... done.
5 把186的/home/guol/ 186-local推送到159的 /home/guol/目录下
#!/usr/bin/python
from fabric.api import *
from fabric.colors import *
from fabric.context_managers import *
env.hosts=[‘10.1.6.159‘]
env.password=‘xxxxxx‘
def task1():
print(green("I‘m 159 /home/guol/"))
with cd(‘/home/guol‘):
run(‘ls -l‘)
def task2():
print(green("I‘m put 186‘s 186-local file to 159"))
put(‘/home/guol/186-local‘,‘/home/guol‘)
print(yellow("I‘m 159 /home/guol/"))
with cd(‘/home/guol‘):
run(‘ls -l‘)
def deploy():
execute(task1)
execute(task2)
##执行
[email protected]:/tmp# fab deploy
[10.1.6.159] Executing task ‘deploy‘
[10.1.6.159] Executing task ‘task1‘

[10.1.6.159] out:
Done.
Disconnecting from 10.1.6.159... done.
7 在186上打开一个159的交互式的shell
#!/usr/bin/python
from fabric.api import *
from fabric.colors import *
from fabric.context_managers import *
env.hosts=[‘10.1.6.159‘]
env.password=‘xxxxxx‘
def task3():
open_shell("ifconfig eth0|grep ‘10.1.6.159‘")
def deploy():
execute(task3)
##执行
[email protected]:/tmp# fab deploy
