• Ansible-变量及加密

    1.变量命名
    只能包含数字，下划线，字母
    只能用下划线或字母开头

    2.变量级别
    全局:    从命令行或配置文件中设定的
    paly:    在play和相关结构中设定的
    主机:    由清单，事实收集或注册的任务

    变量优先级设定: 狭窄范围有限与广域范围

    1. tasks:
    2. - name: create user
    3. user:
    4. name: "{{ USER }}"

    3.4 设定主机变量和清单变量

    1. [admin@ansible .ansible]$ cat inventory 
    2. [westos1]
    3. 172.25.32.11
    4.  
    5. [westos2]

    3. [admin@ansible .ansible]$ vim group_vars/westos.yml
    4. [admin@ansible .ansible]$ cat  group_vars/westos.yml 
    5. WESTOS: hello westos
    6. [admin@ansible .ansible]$ cat user.yml 
    7.   - name: create user
    8.     hosts: westos
    9.     tasks:
    10.       - debug:
    11.           msg: "{{WESTOS}}"
    1. 测试在目录中定义的变量

    2. [admin@ansible .ansible]$ cat user_var.yml 
    3. USER:
    4.   lee:
    5.     age: 18
    6.     obj: linux
    7.

    3.8 注册变量

    register 把模块输出注册到指定字符串中

    1. [admin@ansible .ansible]$ cat westos.yml 
    2. - name: test register
    3.   hosts: 172.25.32.11
    4.   tasks:

    17.

    3.9 事实变量

    事实变量是ansible在受控主机中自动检测出的变量
    事实变量中还有与主机相关的信息

    当需要使用主机相关信息时不需要采集赋值,直接调用即可
    因为变量信息为系统信息所以不能随意设定仅为采集信息,故被成为事实变量

    ather_facts: no     ##在playbook中关闭事实变量收集

    ansible westos -m  setup | less  #查看清单中受控机的全部信息

    1. [admin@ansible .ansible]$ cat register.yml 
    2. - name: test register
    3.   hosts: 172.25.32.11
    4.   tasks:

    4. JINJA2模板

    介绍:
    Jinja2是Python下一个被广泛应用的模版引擎
    他的设计思想来源于Django的模板引擎,
    并扩展了其语法和一系列强大的功能。
    其中最显著的一个是增加了沙箱执行功能和可选的自动转义功能

    4.1 j2模板书写规则

    {# /etc/hosts line #}       ##注释说明文件用途
    127.0.0.1   localhost     ##文件内容
    {{ ansible_facts['all_ipv4_addresses'] }}    {{ansible_facts['fqdn']}}      ##使用事实变量

    4.2 for循环

    1. vim users.yml
    2. users:
    3.   - westos
    4.   - linux
    5.   - ansible
    6.  
    7. vim test.j2
    8. {% for NAME in users %}
    9. {{ NAME }}
    10. {%endfor%}

    4.3 if 判定

    1. #if 判定#
    2.  
    3. {% for NAME in users if not NAME == "ansible" %}
    4. User number {{loop.index}} - {{ NAME }}
    5. {%endfor%}
    6.  
    7. loop.index   ##循环迭代记数从1开始 
    8. loop.index0  ##循环迭代计数从0开始
    9.  
    10. {% for user in students %}
    11. name:   {{user['name']}}
    12. {%if user['age'] is defined%}
    13. age:    {{user['age']}}
    14. {%endif%}
    15. {% if user['age'] is not defined %}
    16. age:    null
    17. {% endif%}
    18. obj:    {{user['obj']}}
    19. {%endfor%}
