Role 디렉토리 만들기

위의 roles/mysql 하위 디렉토리 구조가 복잡한데, 아래 명령어로 mysql role 을 작성하는데 디렉토리를 구성할 수 있다.

cd roles
ansible-galaxy init mysql

Role 작성하기

roles/mysql/tasks/main.yml 에 tasks 를 작성한다.

- name: Install MySQL Packages
  yum:
    name: mysql
    state: present
    
- name: Configure Database
  mysql_db:
    name: db1
    state: present

Playbook 에서 role 사용하기

- name: Install and Configure MySQL
  hosts: db-server
  roles:
    - mysql

ansible-galaxy command

ansible-galaxy search mysql
ansible-galaxy install geerlingguy.mysql
ansible-galaxy list

# check role path
ansible-config dump | grep ROLE

ansible-galaxy role 사용하기

ansible-galaxy role install
