我想在整个剧本中只运行一次处理程序.

我尝试在playbook文件中使用下面的include语句,但这导致处理程序多次运行,每次播放一次:

- name: Configure common config
  hosts: all
  become: true
  vars:
        OE: "{{ ansible_hostname[5] }}"
  roles:
    - { role: common }
  handlers:
    - include: handlers/main.yml

- name: Configure metadata config
  hosts: metadata
  become: true
  vars:
        OE: "{{ ansible_hostname[5] }}"
  roles:
    - { role: metadata }
  handlers:
    - include: handlers/main.yml

这是handlers/main.yml的内容:

- name: restart autofs
  service:
    name: autofs.service
    state: restarted

以下是通知处理程序的任务之一的示例:

- name: Configure automount - /opt/local/xxx in /etc/auto.direct
  lineinfile:
     dest: /etc/auto.direct
     regexp: "^/opt/local/xxx"
     line: "/opt/local/xxx   -acdirmin=0,acdirmax=0,rdirplus,rw,hard,intr,bg,retry=2  nfs_server:/vol/xxx"
  notify: restart …

因此，我对 Linux 服务器序列号的 ansible“内置”事实进行了高低审视，而且如果没有自定义的 dmidecode ansible 模块，它似乎不可用。真的是这样吗？我觉得奇怪的是，由于有大量内置的 ansible 事实，序列号没有包括在内。
