+## description
+
+서버 계정을 이전할 때 OS에 대한 기본 설정하는 부분을 편하게 set up 하기 위해 만든 ansible script 입니다.
+
+ansible 은 기본적으로 ssh 연결을 통해 스크립트를 실행하는 노드에서 host 에 적힌 노드들에게 연결을 보내는 형태입니다. 즉, 컨트롤 노드에만 ansible 을 설치하여 host 연결만 해두고 스크립트를
+실행하면 됩니다.
+
+### ansible.cfg
+
+### inventory
+
+```
+[wishboard-dev-server] # 제어할 노드의 이름 (playbook 파일의 hosts 에 연결되는 값)
+127.0.0.1 # ip 주소
+```
+
+### playbook
+
+- hosts: 플레이의 작업을 실행할 제어 노드를 지정
+- vars: 작업 수행 시 사용할 변수를 정의
+  - tasks 에서 변수 사용 시 `{{ 변수명 }}` 처럼 사용
+- tasks: 실행할 작업들을 지정 (github actions 에 job)
+  - tasks 는 별도의 파일로 step 만 묶어서 생성해둘 수 있으나 현재는 한 파일에 다 정의해둔 상태
+
+## started
+
+### 1) setting
+
+- local pc 에 ansible 설치
+
+```bash
+# mac 의 경우
+brew install ansible
+ansible --version
+```
+
+- local pc 에서 ansible 을 이용해서 ssh 접속하기 위해 ssh 설정 필요
+
+```bash
+# 1. local pc 의 is_rsa.pub 키 값 복사
+# 2. ec2 접속해서 ~/.ssh/authorized_keys 에 추가
+cd ~/.ssh
+vim authorized_keys
+```
