python部署工具fabric

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

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

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'
