Ansible 按主机变量分组

如何缩短此代码，以便在按主机分组时不会重复？而不是重复rhel5、rhel6和rhel7块。我试过_项目，但没有运气

---
- hosts: "{{hosts}}"
  remote_user: root
  tasks:
    - group_by: key=rhel{{ansible_distribution_major_version}}    
- hosts: rhel5
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

- hosts: rhel6
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

- hosts: rhel7
  tasks:
    - debug: msg="{{ansible_distribution}} {{ansible_distribution_release}} {{ansible_distribution_version}}"

您可以使用：

如果您只需要一些东西，您可以使用：

- hosts: rhel*:!rhel4

- hosts: rhel*:!rhel4
