vars

定义方法

第一种定义方法

---
- hosts: testB
  vars:                 定义变量
    var1: file          变量值
  remote_user: root
  tasks:
  - name: touch file
    file: path=/testdir/{{var1}} state=touch

第二种定义方法

---
- hosts: testB
  vars:
    - var1: file
  remote_user: root
  tasks:
  - name: touch file
    file: path=/testdir/{{var1}} state=touch

定义多个变量

第一种

---
- hosts: testB
  vars:
    - var1: file
    - var2: file2
  remote_user: root
  tasks:
  - name: touch file
    file: path=/testdir/{{var1}} state=touch
  - name: touch file2
    file: path=/testdir/{{var2}} state=directory

第二种

---
- hosts: testB
  vars:
    var1: file
    var2: file2
  remote_user: root
  tasks:
  - name: touch file
    file: path=/testdir/{{var1}} state=touch
  - name: touch file2
    file: path=/testdir/{{var2}} state=directory

第三种：属性定义

引用变量属于开头位置要用引号引起来

---
- hosts: testB
  remote_user: root
  vars:
    httpd:
      conf80: /etc/httpd/conf.d/80.conf
      conf8000: /etc/httpd/conf.d/8000.conf

  tasks:
   - name: task1
     file: path={{httpd.conf80}} state=touch
   - name: task2
     file:
       path: "{{httpd.conf8000}}"
       state: touch

---
- hosts: testB
  remote_user: root
  vars:
    httpd:
      conf80: /etc/httpd/conf.d/80.conf
      conf8000: /etc/httpd/conf.d/8000.conf

  tasks:
   - name: task1
     file: path={{httpd.conf80}} state=touch
   - name: task2
     file:
       path: "{{httpd['conf8000']}}"                      区别
       state: touch

变量文件分离

写入文件

vim httpd_vars.yml

httpd:
  conf80: /etc/httpd/conf.d/80.conf
  conf8000: /etc/httpd/conf.d/8000.conf

playbook:

---
- hosts: testB
  remote_user: root
  vars_files:
  - httpd_vars.yml
  tasks:
  - name: task1
    file: path={{httpd.conf80}}
          state=touch
  - name: task2
    file:
      path: "{{httpd['conf8000']}}"
      state: touch

---
- hosts: testB
  remote_user: root
  vars:
  - conf80: /etc/httpd/conf.d/80.conf
  vars_files:
  - httpd_vars.yml

  tasks:
  - name: task1
    file: path={{conf80}}
          state=touch
  - name: task2
    file:
      path: "{{httpd['conf8000']}}"
      state: touch
