• fabric批量操作远程操作主机的练习


    fabric是python的一个基于命令行的自动化部署框架,用docker开了两个容器来学习fabric.

    #!/usr/bin/env python
    #-*- coding=utf-8 -*-
    
    from fabric.api import *
    
    env.hosts=[
        'root@114.215.86.228:22',
        'root@114.215.86.228:32',
    ]
    env.passwords={
        'root@114.215.86.228:22':'*****',
        'root@114.215.86.228:32':'***',
    }
    @task
    def task1():
        run('ps')
    
    @task
    def task2():
        run('uname -a')
    @task
    def dotask():
        execute(task1)
        execute(task2)

    执行结果

    Done.
    Disconnecting from 114.215.86.228... done.
    Disconnecting from 114.215.86.228:32... done.

    尽管如此,密码是明文,不安全,因此仍然推荐用加key的方式管理服务器。
