本文介绍了Ansible中变量的定义和管理，包括不同范围的变量、定义变量的多种方式，如vars、Vars_files、register和set_fact。还详细讨论了如何通过命令行传递变量，使用内置变量，以及管理机密数据，特别是利用ansible vault进行加密和解密。最后，给出了一个创建和管理Web内容目录的playbook示例。

ansible变量

定义变量规则：由字母/数字/下划线组成，变量需要以字母开头，ansible内置的关键字不能作为变量名。
ansible中，可以将变量简化为三个范围 Global范围（高）：从命令行和ansible配置设置的变量 play范围（中）：在play和相关结构中设置的变量 Host范围（低）：inventory、facts或register的变量，在主机组和个别主机上设置的变量三个范围的变量优先级依次降低，如果变量重复定义，则以优先级高的为准

注册和定义变量的各种方式

ansible中定义变量的方式有很多种，大致有：
(1) 将模块的执⾏结果注册为变量；
(2) 直接定义字典类型的变量；
(3) role中⽂件内定义变量；
(4) 命令⾏传递变量；
(5) 借助with_items迭代将多个task的结果赋值给⼀个变量；
(6) inventory中的主机或主机组变量；
(7) 内置变量。

vars定义变量

register注册变量

使⽤register选项，可以将当前task的输出结果赋值给⼀个变量。

[student@ansible ansible]$ vim sb.yml 
---
- name: register注册变量
  hosts: dev
  tasks: 
    - name: shell
      shell: "cat /tmp/zz"
      register: zz
    - name: 创建debug
      debug: 
        var: zz

TASK [创建debug] *****************************************************************
ok: [node1] => {
    "zz": {
        "changed": true,
        "cmd": "cat /tmp/zz",
        "delta": "0:00:00.003963",
        "end": "2022-10-25 23:21:23.533205",

        "stderr": "",
        "stderr_lines": [],
        "stdout": "hello zz",
        "stdout_lines": [
            "hello zz"
        ]
    }
}

管理机密

Ansible可能需要访问密码或者API密钥等敏感数据，以便配置受控主机。通常，此信息可能以纯文本形式存储在清单变量或其他ansible文件中。但若如此，任何有权访问ansible文件的用户或者存储这些ansible文件的版本控制系统都能够访问此敏感数据。这显然存在安全风险。
使用ansible随附的ansible vault 可以加密和解密任何由ansible使用的结构化数据文件。若要使用ansible vault，可通过一个名为ansible-vault的命令行工具创建、编辑、加密、解密和查看文件。Ansible vault可以加密任何由ansible使用的结构化数据文件。这可能包括清单变量、playbook中含有的变量文件、在执行playbook时作为参数传递的变量文件，或者ansible角色中定义的变量。

创建加密的文件

要创建新的加密文件，使用ansible-vault create filename命令，默认使用vi编辑

[student@ansible ansible]$ ansible-vault create sb.yml
New Vault password: 1
Confirm New Vault password: 1
---
- name: test1
  hosts: node1
  tasks:
    - name: create user2
      user:
        name: user2
        state: present

默认使用ansile-playbook test.yml会执行失败

[student@ansible ansible]$ ansible-playbook sb.yml 
ERROR! Attempting to decrypt but no vault secrets found

查看加密的文件

[student@ansible ansible]$ ansible-vault view sb.yml 
Vault password: 1
---
- name: test1
  hosts: node1
  tasks:
    - name: create user2
      user:
        name: user2
        state: present

编辑现有的加密文件

[student@ansible ansible]$ ansible-vault edit sb.yml 
Vault password: 1

加密现有的文件

[student@ansible ansible]$ ansible-vault encrypt sb.yml  
New Vault password: 1
Confirm New Vault password: 1

解密现有的文件

现有的加密文件可以通过ansible-vault decrypt filename命令永久解密。在解密单个文件时，可使用–output选项以其他名称保存解密文件。
1、直接解密

[student@ansible ansible]$ ansible-vault decrypt sb.yml  
Vault password: 
Decryption successful
[student@ansible ansible]$ cat sb.yml 
---
- name: test1
  hosts: node1
  tasks:
    - name: create user2
      user:
        name: user2
        state: present

2、解密文件并存放为其他名称，原文件仍然处于加密状态(其中原文件a.yml仍处于加密状态，a-secret.yml处于解密状态)

[student@ansible ansible]$ ansible-vault  decrypt  a.yml  --output=a-secret.yml

更改加密文件的密码

ansible-vault  rekey  filename命令可以修改
[student@ansible ansible]$ ansible-vault rekey sb.yml 
Vault password: 1
New Vault password: 2
Confirm New Vault password: 2
Rekey successful

加密后的文件直接用playbook执行会报错，那么该使用什么命令呢？
使用选项–vault-id @prompt或者–ask-vault-pass都可

[student@ansible ansible]$ ansible-vault create jj.yml
New Vault password: 
Confirm New Vault password: 
[student@ansible ansible]$ ansible-playbook --ask-vault-pass jj.yml 
Vault password:

拓展

创建Web内容目录
按照下方所述，创建一个名为 /home/student/ansible/sb.yml 的 playbook：
该 playbook 在 dev 主机组中的受管节点上运行
创建符合下列要求的目录 /webdev：
所属组为 devops 组
具有常规权限：owner=read+write+execute，group=read+write+execute，other=read+execute
具有特殊权限: set group ID
用符号链接将/webdev目录链接到/var/www/html/webdev
创建文件 /webdev/index.html，其中包含如下所示的单行文本：Development
在 dev 主机组中主机上浏览此目录（例如 http://node1.example.com/webdev/ ）将生成以下输出：
Development

[student@ansible ansible]$ pwd
/home/student/ansible
[student@ansible ansible]$ vim sb.yml
[student@ansible ansible]$ ansible-playbook sb.yml 
[student@ansible ansible]$ cat sb.yml
