[응용] 다양한 환경을 앤서블(Ansible)로 관리하기 with 베이그런트(Vagrant) - 인프런 | 강의

 

ㅇ 앤서블 노드에 nginx 설치 및 테스트 그리고 삭제하기

 - nginx_isntall.yaml 작성

# gather_facts 관련

  > https://ossian.tistory.com/98

# become  => root 권한 획득

# *  기존 yum:

               name:

      형식(여러줄)과 yum: name=  (한줄) 은 동일하게 작용

  2 - name: Install nginx on CentOS
  3   hosts: CentOS
  4   gather_facts: no
  5   become: yes
  6
  7   tasks:
  8     - name: install epel_release
  9       yum: name=epel-release state=latest
 10     - name: install nginx web server
 11       yum: name=nginx state=present
 12     - name: Upload default index.html for web server
 13       get_url: url=https://www.nginx.com dest=/usr/share/nginx/html/ mode=0644
 14     - name: Start nginx web server
 15       service: name=nginx state=started

 

- nginx_remove.yaml 작성

# yum 모듈에서 state를 absent (비어있음) 으로 설정하여 삭제함

  1
  2 - name: Remove nginx on CentOS
  3   hosts: CentOS
  4   gather_facts: no
  5   become: yes
  6
  7   tasks:
  8     - name: remove epel_release
  9       yum: name=epel-release state=absent
 10     - name: remove nginx web server
 11       yum: name=nginx state=absent

 

 

 

작성 후, # ansible-playbook nginx_install -k 로 실행

 

ㅇ 시간대(timezone) 변경하기

- timezone.yaml 작성

  1 ---
  2 - name: Setup linux timezone
  3   hosts: CentOS
  4   gather_facts: no
  5   become: yes
  6
  7   tasks:
  8     - name: set timezone to Asia/Seoul
  9       timezone: name=Asia/Seoul

 

- 적용 및 결과

 

ㅇ NFS 서버와 클라이언트 구성하기

- nfs.yaml 작성 후 실행!

  1
  2 - name: Setup for nfs server & clients
  3   gather_facts: no
  4   hosts: localhost
  5
  6   tasks:
  7     - name: make nfs_shared directory
  8       file:
  9         path: /home/vagrant/nfs_shared
 10         state: directory
 11         mode: 0777
 12     - name: configure /etc/exports
 13       become: yes
 14       lineinfile:
 15         path: /etc/exports
 16         line: /home/vagrant/nfs_shared 192.168.0.0/24(rw,sync)
 17
 18     - name: nfs service restart
 19       become: yes
 20       service:
 21         name : nfs
 22         state : restarted
 23
 24 - name : Setup for nfs clients

 32         state: directory
 33     - name: mount point directory as client
 34       become: yes
