ansible-playbook(2)

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

   

条件测试： when条件测试

- hosts: all
  remote_user: root
  vars:
  - username: user2 
  tasks: 
  - name: create {{ username  }} user
    user: name={{ username }}
    when: ansible_distribution == "CentOS"
