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
root@vm11:/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
root@vm11:/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
root@vm11:/tmp# fab deploy

-rw-r--r-- 1 root root 0 Dec 21 14:28 159-remote
-rw-r--r-- 1 root root 0 Dec 21 13:32 186-local

Done.
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
root@vm11:/tmp# fab deploy
[10.1.6.159] Executing task ‘deploy‘
[10.1.6.159] Executing task ‘task1‘
I‘m 159 /home/guol/
[10.1.6.159] run: ls -l
[10.1.6.159] out: total 0
[10.1.6.159] out: -rw-r--r-- 1 root root 0 Dec 21 13:32 159-remote
[10.1.6.159] out: 

[10.1.6.159] Executing task ‘task2‘
I‘m put 186‘s 186-local file to 159
[10.1.6.159] put: /home/guol/186-local -> /home/guol/186-local
I‘m 159 /home/guol/
[10.1.6.159] run: ls -l
[10.1.6.159] out: total 0
[10.1.6.159] out: -rw-r--r-- 1 root root 0 Dec 21 13:32 159-remote
[10.1.6.159] out: -rw-r--r-- 1 root root 0 Dec 21 14:33 186-local
[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
root@vm11:/tmp# fab deploy
[10.1.6.159] Executing task ‘deploy‘
[10.1.6.159] Executing task ‘task3‘
