Python自动化部署工具Fabric的简单上手指南

pip install fabric

from fabric.api import local

vim fabrile.py

#coding:utf-8
from fabric.api import local#
def hello():
   # local函数用来执行本地命令
   local('echo "hello wolrd!"')

fab hello

[localhost] local: echo "hello world!"
hello world!
Done.

$ ssh x.x.x.x 'uname -a' -- 输出略

$ cat fabfile.py
