Create a playbook called /home/student/ansible/packages.yml that:
Installs the php and mariadb packages on hosts in the dev, test, and prod host groups
Installs the RPM Development Tools package group on hosts in the dev host group
Updates all packages to the latest version on hosts in the dev host group
一．解題過程：
[student@workstation ansible]$ touch packages.yml
[student@workstation ansible]$ vim packages.yml
---
- name: install packages
hosts: dev,test,prod
tasks:
- name: install php and mariadb
dnf:
name: "{{ item }}"
state: present
loop:
- php
- mariadb
- name: install devtools on host dev
dnf:
name: rpmdevtools
hosts: dev,test,prod
tasks:
- name: install php and mariadb
dnf:
name: "{{ item }}"
state: present
loop:
- php
- mariadb
- name: install devtools on host dev
dnf:
name: rpmdevtools
\\考題這裡要下載的是'@RPM Development Tools'，不過我沒有這包套件，就改成官方的rpmdevtools，應該也是類似的東西
state: present
when: ansible_hostname in groups.dev
- name: upgrade all packages on host dev
dnf:
name: '*'
state: latest
when: ansible_hostname in groups.dev
state: present
when: ansible_hostname in groups.dev
- name: upgrade all packages on host dev
dnf:
name: '*'
state: latest
when: ansible_hostname in groups.dev
[student@workstation ansible]$ ansible-playbook -C packages.yml \\測試此命題能否運作
[student@workstation ansible]$ ansible dev -m shell -a 'rpm -qa | grep mariadb'
[student@workstation ansible]$ ansible dev -m shell -a 'rpm -qa | grep php'
\\驗證dev節點是否有安裝完畢
 |
| 回傳訊息是這樣就表示安裝成功 |
二．恢復解題前的環境
[student@workstation ansible]$ vim 04-lab-collection-stop.yml
---
- name: remove packages
hosts: dev,test,prod
tasks:
- name: remove php mariadb
yum:
name: "{{ item }}"
state: absent
loop:
- php
- mariadb
- name: remove packages groups
yum:
name: "rpmdevtools"
state: absent
when: inventory_hostname in groups['dev']
- name: remove package.yml
hosts: 127.0.0.1
tasks:
- name: remove package.yml
file:
path: /home/student/ansible/packages.yml
state: absent
