1. 우선 롤부터 생성한다.(arole) 

[root@asimblecontroller ansible]' ansible-galaxy role init arole
- Role arole was created successfully

[root@asimblecontroller ansible]' tree arole

2. Role 변수설정

[root@asimblecontroller ansible]' vi arole/vars/main.yml

---
' vars file for arole
service_name: httpd
src_file_path: ../files/index.html
dest_file_path: /var/www/html
httpd_packages:
  - httpd-tools
  - httpd
supported_distors:
  - CentOS
  - RedHat

3. apache 재시작 handlers 만들기

[root@asimblecontroller ansible]' vi arole/handlers/main.yml

---
' handlers file for arole

- name: restart service
  ansible.builtin.service:
    name: "{{ service_name }}"
    state: restarted

4. default 변수 생성 

---
' defaults file for arole
service_title: "Apache web service"

5. index.html 파일 생

[root@asimblecontroller ansible]' vi arole/files/index.html

내용은 

Hello albert

6. 수행할 task 생성

(수행할 작업은 우선 http yum 설치 실행후 files/index.html 파일을 /var/www/html 폴더로 복사이동처리후 apache 서비스를 재시작시크는 작업이다.)

[root@asimblecontroller ansible]' vi arole/tasks/main.yml

' tasks file for arole

- name: install service {{ service_title }}
  ansible.builtin.yum:
    name: "{{ item }}"
    state: latest
  loop: "{{ httpd_packages }}"
  when: ansible_facts.distribution in supported_distors

- name: copy html file
  ansible.builtin.copy:
    src: "{{ src_file_path }}"
    dest: "{{ dest_file_path }}"
  notify:
    - restart service

7. role을 실행할 playbook만들기

- hosts: web

  tasks:
    - name: Print start play
      ansible.builtin.debug:
        msg: "Play Apache setup role"

    - name: Install service by role
      ansible.builtin.import_role:
        name: arole

8. 실행결과

[root@asimblecontroller ansible]' ansible-playbook httpdSetup.yml

PLAY [web] **********************************************************************************

TASK [Gathering Facts] **********************************************************************
ok: [tnode1]

TASK [Print start play] *********************************************************************
ok: [tnode1] => {
"msg": "Start role play"
}

TASK [arole : install service Apache web service] *******************************************
ok: [tnode1] => (item=httpd-tools)
ok: [tnode1] => (item=httpd)

TASK [arole : copy html file] ***************************************************************
changed: [tnode1]

RUNNING HANDLER [arole : restart service] ***************************************************
changed: [tnode1]

PLAY RECAP **********************************************************************************
tnode1                     : ok=5    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

tnode1 서버에서 http://localhost 로 접속시 조금전 만든 index.html 내용이 출력되는부분 확인할수있다.
