一、在剧本的当前目录创建templates文件夹（template只能在剧本使用）
二、例子
2.1
[root@linux-node1 ansible]# cat test_template.yaml
---
- hosts: date
remote_user: root
tasks:
- name: install package
yum: name=nginx
- name: copy template
template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
- name: start service
service: name=nginx state=started enabled=yes
ansible-playbook test_template.yaml
2.1修改templates文件（ansible_processor_vcpus cup个数）
vim templates/nginx.conf.j2
handlers、notify定义重启规则
[root@linux-node1 ansible]# cat test_template1.yaml
---
- hosts: date
remote_user: root
tasks:
- name: install package
yum: name=nginx
- name: copy template
template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
notify: restart service
- name: start service
service: name=nginx state=started enabled=yes
handlers:
- name: restart service
service: name=nginx state=restarted
ansible-playbook test_template1.yaml
3.1修改端口（自定义变量）
vim /etc/ansible/hosts
vim templates/nginx.conf.j2
4.1、在剧本中定义变量
[root@linux-node1 ansible]# cat test_template1.yaml
---
- hosts: date
remote_user: root
vars:
- http_port: 99
tasks:
- name: install package
yum: name=nginx
- name: copy template
template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
notify: restart service
- name: start service
service: name=nginx state=started enabled=yes
handlers:
- name: restart service
service: name=nginx state=restarted
最后结果：/etc/ansible/hosts（ [date:vars]组 < [date]中 ）< ansible-playbook <ansible-playbook -e定义
