第
3
章
Linux
本章旨在帮助读者熟悉
Linux
基础知识,该操作系统在网络界已经变得越来越普及。你可
能好奇为什么要在本书中加入
Linux
的相关章节
。说到底,
Linux
这款类
Unix
操作系统跟
网络自动化和可编程性有什么关系呢?
3.1
网络自动化场景中的
Linux
从网络自动化的角度来看
Linux
,以下几点原因让我们认为本章的内容非常重要。
首先,一些现代
NOS
均基于
Linux
,尽管其中一部分采用的是定制的
CLI
,观感或用
法与
Linux
不同
。另一部分则开放了
Linux
的内部组织结构,并且可以使用
Linux shell
(如
bash
)。
其次,一些新的公司和组织向市场推出了针对网络设备的全功能
Linux
发行版
。例如,开
放计算项目(
Open Compute
Project
,
OCP
)最近选择了开放网络
Linux
(
Open Network
Linux
,
ONL
)作为基础
,在其之上构建了基于
Linux
的
NOS
(
Big Switch Networks
的
Switch Light
也是
如此)。
Cumulus Networks
则是另一个例子,在其所支持的硬件平台上使
用基于
Debian
的
Cumulus Linux
作为
NOS
。身为网络工程师,为了配置网络,你可能越来
越需要了解
Linux
。
最后,本书中讨论的很多工具源自
Linux
,或者要求在
Linux
系统中运行
。例如,
Ansible
(第
9
章会讨论该工具)需要用到
Python
(第
4
章的讨论主题)
。由于在第
9
章中会讲到的
一些其他原因,在使用
Ansible
自动化网络设备时 ...
