这是Ansible官方网站的介绍，本着学习的态度我决定一边学习一边翻译Ansible configure management这本书，原文下载稍后放出
#一些自解释的文字，我会忽略，或者按照自己的理解简单翻译一下，并非每行每句都是一一对应。
Preface Since CFEngine was first created by Mark Burgess in 1993, configuration management tools have been constantly evolving. Followed by the emergence of more modern tools such as Puppet and Chef, there are now a large number of choices available to a system administrator. Ansible is one of the newer tools to arrive into the configuration management space. Where other tools have focused on completeness and configurability, Ansible has bucked the trend and, instead, focused on simplicity and ease of use. In this book, we aim to show you how to use Ansible from the humble beginnings of its CLI tool, to writing playbooks, and then managing large and complex environments. Finally, we teach you how to extend Ansible by writing your own modules.
前言
自从CFEngine 在1993年被Mark Burgess开发出来之后，配置管理工具就层出不穷了。像puppet 和chef，系统管理员可以有很多选择。Ansible 是一个新的配置管理工具，与其他工具不同的是，其他管理工具注重的是完整性和可配置性，而Ansible注重的是简单性和易用性。
What this book covers Chapter 1, Getting Started with Ansible, teaches you the basics of Ansible, how to build an inventory, how to use modules, and, most importantly, how to get help. Chapter 2, Simple Playbooks, teaches you how to combine multiple modules to create Ansible playbooks to manage your hosts. Chapter 3, Advanced Playbooks, delves deeper into Ansible's scripting language and teaches you more complex language constructs. Chapter 4, Larger Projects, teaches you the techniques to scale Ansible configurations to large deployments containing many complicated systems. Chapter 5, Custom Modules, teaches you how to expand Ansible beyond its current capabilities.

Who this book is for This book is intended for those who want to understand the basics of how Ansible works. It is expected that you have rudimentary knowledge of how to set up and configure Linux machines. In parts of the book, we cover the configuration files of BIND, MySQL, and other Linux daemons; a working knowledge of these would be helpful, but is certainly not required.
合适的读者
给那些愿意进一步了解Ansible工作原理的人。本书预计你对配置linux设备有一定的基础知识，在书中会举一些关于linux-mind、mysql等linux服务配置，如果你之前接触过这些配置会对你理解本书有帮助，但这些不是必须的！
Conventions In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning. Code words in text are shown as follows: "We can include other contexts through the use of the include directive." A block of code is set as follows: [group] machine1 machine2 machine3 [ 2 ]Preface When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold: tasks: - name: install apache action: yum name=httpd state=installed - name: configure apache copy: src=files/httpd.conf dest=/etc/httpd/conf/httpd.conf Any command-line input or output is written as follows: ansible machinename -u root -k -m ping New terms and important words are shown in bold.
