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

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 '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
root@vm11:/tmp# fab deploy
[10.1.6.159] Executing task 'deploy'
[10.1.6.159] Executing task 'task3'
