简介：
在python3下使用fabic的方法。
python3.6.1 下安装fabric
$ workon py3.6.1env
(py3.6.1env)$ pip install Fabric
(py3.6.1env)$ fab -V
Traceback (most recent call last):
File "/root/.virtualenvs/py3.6.1env/bin/fab", line 7, in
from fabric.main import main
File "/root/.virtualenvs/py3.6.1env/lib/python3.6/site-packages/fabric/main.py", line 13, in
from operator import isMappingType
ImportError: cannot import name 'isMappingType'
python2.7.5 下安装fabric
$ pip install Fabric
$ fab -V
Fabric 1.13.2
Paramiko 1.16.1
fabric 应用举例
$ cat fabfile.py
from fabric.api import run
def host_type():
run('uname -s')
run('uptime')
$ fab host_type

部署代码：
一个部署代码的fabric脚本：
# filename: fabricfile.py
# -*- coding:utf-8 -*-
from fabric.api import run
from datetime import datetime
from fabric.api import *
# 登录用户和主机名：
env.user = 'root'
env.password='123.com'
#env.hosts = ['172.28.32.49','172.28.32.50',
# '172.28.32.51','172.28.32.53',
# ]
#
#env.hosts = ['172.28.32.49','172.28.32.50']
env.hosts = ['172.28.32.51','172.28.32.53']

#cd('')
UOP_BACKEND = '/opt/uop-backend'
with cd(UOP_BACKEND):
run("git pull ")
#run("git pull --rebase")
def deploy_cmdb_backend():
#NOTE: 在deploy_cmdb_backend中使用自己独立的hosts的没有效果。
env.hosts = ['172.28.32.49','172.28.32.50']
#cd('')
CMDB_BACKEND = '/opt/cmdb-backend'
with cd(CMDB_BACKEND):

执行：
fab [方法]， 命令行中选择不同的方法，来执行不同的逻辑。
$ fab deploy_uop_frontend
