cat /etc/ansible/hosts

　　

 

 

cat templates/nginx.conf.j2

 

- hosts: test
  remote_user: root
  vars:
  - package: httpd
  - service: httpd
  tasks:
  - name: install nginx package
    yum: name={{ package }} state=latest
  - name: install configuration file for httpd
    template: src=/root/templates/httpd.conf.j2 dest=/etc/httpd/conf/httpd.conf
    notify: 
    - restart httpd
    
  - name: start httpd service
    service: enabled=true name={{ service }} state=started
  handlers:
  - name: restart httpd
    service: name={{ package }} state=restarted

 

tags 标签

<u><!--Tags用于选择运行或路过playbook中的部分代码，ansible具有幂等性，因此会自动跳过没有变化的部分，即便如此，有些代码为测试其确实没有发生变化的时间依然会非常长，此时，如果确信其没有变化，就可以通过tags跳过此些代码片段--></u>

- hosts: test
  remote_user: root
  vars:
  - package: nginx
  - service: nginx
  tasks:
  - name: install nginx package
    yum: name={{ package }} state=latest
    tags:
    - install
  - name: configuration file for httpd
    tags:
    - conf
    template: src=/root/templates/nginx.conf.j2 dest=/etc/nginx/nginx.conf
    notify: 
    - restart nginx
  - name: start nginx service
    shell: nginx
    tags:
    - start_nginx  
  handlers:
  - name: restart nginx
    shell: nginx -s reload
    
 # ansible-playbook nginx_temp.yml --tags="conf" 指定tags运行
 # 特殊tags: always 无论如何都会运行
