简单例子1: vars定义变量

• - hosts: all
   remote_user: root
   vars:
   - package: nginx
   - service: nginx
     tasks:
   - name: install nginx package
     yum: name={{ package }} state=latest
   - name: install configuration file for httpd
     copy: src=/etc/nginx/nginx.conf dest=/etc/nginx/nginx.conf
     notify:
         - restart nginx
  ​
  - name: start httpd service
   service: enabled=true name={{ service }} state=started
  handlers:
  - name: restart nginx
   service: name={{ package }} state=restarted
