Ansible로 서버 자동화하기

Ansible 기본 사용법:

1. 인벤토리 (hosts):

# /etc/ansible/hosts 또는 inventory.yml
[webservers]
web1 ansible_host=192.168.1.10
web2 ansible_host=192.168.1.11

[dbservers]
db1 ansible_host=192.168.1.20

2. Playbook (자동화 스크립트):

# deploy.yml
---
- hosts: webservers
  become: yes
  tasks:
    - name: Update apt cache
      apt: update_cache=yes

    - name: Install nginx
      apt: name=nginx state=latest

    - name: Start nginx
      service: name=nginx state=started enabled=yes

    - name: Copy config
      template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
      notify: restart nginx

  handlers:
    - name: restart nginx
      service: name=nginx state=restarted

실행:

ansible-playbook -i inventory.yml deploy.yml

SSH만 되면 에이전트 설치 없이 동작합니다.
