ansible的roles角色

建立樹狀目錄
[root@zxw8 ~]# mkdir -pv playbook/roles/{dbservers,webservers}/{files,handlers,tasks,templates,vars}
本地安裝tree
[root@zxw8 ~]# cd Packages/
[root@zxw8 ~]# rpm -ivh tree-1.6.0-10.el7.x86_64.rpm
yum安裝
[root@zxw8 ~]# yum install tree -y

建立任務tasks
[root@zxw8 playbook]# vim roles/dbservers/tasks/main.yaml
- name: service httpd restarted
service: name=httpd state=restarted
- name: touch file
command: touch /root/a.txt
[root@zxw8 playbook]# ls
Roles
建立執行任務的角色roles
[root@zxw8 playbook]# vim site.yaml
- hosts: zxw
remote_user: root
roles:
- dbservers
[root@zxw8 playbook]# ansible-playbook site.yaml
複製文件files
[root@zxw8 playbook]# cp /etc/httpd/conf/httpd.conf roles/dbservers/files/
[root@zxw8 playbook]# vim roles/dbservers/tasks/main.yaml

- name: service httpd restarted
service: name=httpd state=restarted
- name: touch file
command: touch /root/a.txt
- name: cp httpd.conf
copy: src=httpd.conf dest=/etc/httpd/conf/httpd.conf

變量定義vars
[root@zxw8 playbook]# vim roles/dbservers/vars/main.yaml

file: httpd.conf

觸發器：handlers
[root@zxw8 playbook]# vim roles/dbservers/tasks/main.yaml

- name: service httpd restarted
service: name=httpd state=restarted
- name: touch file
command: touch /root/a.txt
- name: cp httpd.conf
copy: src={{ file }} dest=/etc/httpd/conf/{{ file }}
notify:
- service httpd restarted
~
[root@zxw8 playbook]# vim roles/dbservers/handlers/main.yaml

- name: service httpd restarted
service: name=httpd state=restarted

Templates
[root@zxw8 playbook]# cp /etc/httpd/conf/httpd.conf roles/dbservers/templates/

[root@zxw8 ~]# vim playbook/roles/dbservers/tasks/main.yaml

- name: service httpd restarted
service: name=httpd state=restarted
- name: touch file
command: touch /root/a.txt
- name: cp httpd.conf
templates: src={{ file }} dest=/etc/httpd/conf/{{ file }}
notify:
- service httpd restarted
