## 二：使用setup

### 1. 案例一

使用“ansible_fqdn”获取主机名称和域名

```bash
[root@ansible-server ansible]# vim hostname.yml  
  1 ---                         
  2 - name: test a playbook     
  3   hosts: ansible-web1       
  4   tasks:                    
  5   - name: hostname          
  6     debug:                  
  7       msg: "{{ ansible_fqdn }}"
```

运行剧本：

```bash
[root@ansible-server ansible]# ansible-playbook hostname.yml 

PLAY [test a playbook] *********************************************************
