ansible基础-playbook剧本的使用

一.YAML概述
1>.YAML的诞生
YAML是一个可读性高，用来表达数据序列的格式。 YAML参考了其他多种语言，包括：XML、C语言、Python、Perl以及电子邮件格式RFC2822。 Clark Evans在2001年5月在首次发表了这种语言，另外Ingy döt Net与Oren Ben-Kiki也是这语言的共同设计者。\
2>.YAML的命名
YAML是"YAML Ain't a Markup Language"（YAML不是一种置标语言）的递归缩写。 在开发的这种语言时，YAML 的意思其实是："Yet Another Markup Language"（仍是一种置标语言）。但为了强调这种语言以数据作为中心，而不是以标记语言为重点，而反向缩略语重命名。
3>.YAML的功能
YAML的语法和其他高阶语言类似，并且可以简单表达清单、散列表，标量等资料形态、。
它使用空白符号缩排和大量依赖外观的特色，特别适合用来表达或编辑数据结构、各种设定档、倾印除错内容、文件大纲（例如：许多电子邮件标题格式和YAML非常接近）。
尽管它比较适合用来表达阶层式（hierarchical model）的数据结构，不过也有精致的语法可以表示关联性（relational model）的资料。
由于YAML使用空白字符和分行来分隔资料，使得它他特别适合用grep、Python、Perl、Ruby操作。
其让人最容易上手的特色是巧妙避开各种封闭符号，如：引号、各种括号等，这些符号在嵌套结构中会变得复杂而难以辨认。
4>.JSON格式和YAML格式表现数据结构（基本数据结构）案例对比
JSON格式：
{id:,name:尹正杰,age:,spouse:{id:,name:jason,age:},fav:[red,yellow,blue]} YAML格式：
id:1
name:尹正杰
age:18
spouse:
id:2
name:jason
age:26
fav:
-red
-yellow
-blue
5>.YAML语法检查
其实ansible自带的就有YAML语法检查的脚本，当然你也可以参考网页连接的检查：https://www.bejson.com/validators/yaml/。
二.Playbook的核心元素
Hosts：
定义可以操作的主机， Tasks：
定义我们需要执行的任务列表。 Variable：
支持变量，流程控制语句，如循环语句等等。（YAML支持编程语言的基本语法，如条件表达式，循环语句，流程控制等等，这也是为什么ansible选择它的一个原因吧！） Templates：
包含了模板语法的文本文件。 Handlers：
处理器是由特定条件触发的任务。 Roles：
定义角色，其实我们可以理解角色是将服务器主机进行分组，然后基于组的方式进行批量管理。这个角色和MySQL8.0之后版本的角色功能很相似！
三.运行playbook的方式案例展示
1>.playbook的基础组件
playbook的基础组件：
Hosts：
运行指定任务的目标主机。
remoute_user:
在远程主机上执行任务的用户。
tasks：
任务列表。
模块，模块参数
格式：
action：module arguments
module：arguments
温馨提示：
shell和command模块后面直接跟命令，而非key=value类的参数列表。
某任务的状态在运行后为changed时，可通过“notify”通知给相应的handlers。
任务可以通过“tags”打标签，而后可在ansible-playbook命令上使用-t指定进行调用。
2>.运行playbook的步骤简介
运行playbook的方式：
1>.测试
ansible-playbook --check
只检测可能会发生的改变，但不是真正执行操作。
ansible-playbook --list-hosts
列出运行任务的主机。
ansible-playbook --list-tasks
列出运行的任务列表。
ansible-playbook --syntax-check
语法检查。
2>.运行
3>.编写剧本（注意，每个冒号后面都有一个空格，如果你没写的话，可能会报错！）
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# cat memcached.yaml
- hosts: node102.yinzhengjie.org.cn
remote_user: root
tasks:
- name: 'install memcached package'
yum: 'name=memcached state=installed'
- name: 'start memcached service'
service: 'name=memcached enabled=true state=started'
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]#
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]#
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# cat memcached.yaml
4>.只检测可能会发生的改变，但不是真正执行操作。
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# ansible-playbook --check memcached.yaml PLAY [node102.yinzhengjie.org.cn] *************************************************************************************************************************** TASK [Gathering Facts] **************************************************************************************************************************************

5>.列出运行任务的主机。
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# ansible-playbook --list-hosts memcached.yaml playbook: memcached.yaml play # (node102.yinzhengjie.org.cn): node102.yinzhengjie.org.cn TAGS: []

hosts ():
node102.yinzhengjie.org.cn
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]#
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]#
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# ansible-playbook --list-hosts memcached.yaml
6>.语法检查。如果没有任何的报错就是最好的结果！
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# ansible-playbook --syntax-check memcached.yaml playbook: memcached.yaml
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]#
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]#
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# ansible-playbook --syntax-check memcached.yaml
7>.执行playbook

四.handlers案例展示
1>.handlers用法简介
handlers:
任务,在特定的条件下触发；
接收到其他的任务的通知时被触发：
notify: HANDLER TASK NAME
2>.编写playbook
[root@node101.yinzhengjie.org.cn ~/ansible_workshop]# cat conf/memcached

USER="memcached"
MAXCONN=""

五.variables案例展示
1>.variables简介
variables:
1>.facts: 可直接调用
注意，可使用setup模块直接获取目标主机的facters。
2>.用户自定义变量：
在ansible-playbook命令的命令行中
-e VARS,--extra-vars=VARS
在playbook中定义变量的方法：
vars:
-var1:values1
-var2:values2
变量引用的方法和python的django框架模板语法类似，如：{{ variable }}
3>.通过roles传递变量
4>.Host Inventory
用户自定义变量
向不同的主机传递不同的变量
IP/HOSTNAME varaiable=value var2=value2
向组中的主机传递相同的变量
[groupname:vars]
variable=value
invertory参数
用于定义ansible远程目标连接主机时使用的参数，而非传递给playbook的变量，一般我们在/etc/ansible/hosts 对应的主机后面定义即可
ansible_ssh_host
ansible_ssh_port
ansible_ssh_user
ansible_ssh_pass
ansible_sudo_pass
