ansible 不运行包含角色的处理程序

我正在尝试在同一角色的处理程序上运行通知，并且该角色被包含在依赖项中。

这是我的剧本

root@monitor:/etc/ansible# cat monitor.yml
---

- hosts: local
  connection: local
  become: yes
  become_user: root
  roles:
    - common
    - role: sensu
      sensu_install_server: true

我的常用文件如下

root@monitor:/etc/ansible# cat roles/common/tasks/main.yml
- name: Add the OS specific variables
  include_vars: '{{ ansible_os_family }}.yml'

#
# ansible run script
- name: copy the ansible-run script
  copy:
    src=ansible-run.py
    dest=/usr/bin/ansible-run
    owner=root
    group=root
    mode=0700
- cron: name="cron ansible-run" minute="*/5" job="/usr/bin/ansible-run > /dev/null 2&1"


#
# ntp
- name: Install ntp
  package: name=ntp state=present
- name: Start/stop ntp service
  service: name={{ ntp_service_name }} state=started enabled=yes



root@monitor:/etc/ansible# cat roles/common/meta/main.yml
---
dependencies:
  - { role: users }
  - { role: sensu }

我的 sensu 角色是我希望通知在tasks/client.yml

root@monitor:/etc/ansible# cat roles/sensu/tasks/main.yml

- include: common.yml

- include: server.yml
  when: sensu_install_server
  ignore_errors: true

- include: client.yml





root@monitor:/etc/ansible# cat roles/sensu/tasks/client.yml
- name: reload ansible_local
  setup: filter=ansible_local

- name: copy plugins files
  copy:
    src=files/sensu/plugins/
    dest=/etc/sensu/plugins/
    owner=sensu
    group=sensu
    mode=0750
  notify:
    - restart sensu client


- name: generate config files
  template:
    src=client.json.j2
    dest=/etc/sensu/conf.d/client.json
    owner=sensu
    group=sensu
    mode=0640
    backup=yes
  notify:
    - restart sensu client

- name: enable sensu-client to survive reboot
  service:
    name=sensu-client
    enabled=yes
    state=started



root@monitor:/etc/ansible# cat roles/sensu/handlers/main.yml
---
# handlers file for sensu
- name: restart sensu server
  service: name=sensu-{{ item }} state=restarted
  with_items:
    - server
    - api

- name: restart sensu client
  service: name=sensu-client state=restarted

- name: restart uchiwa service
  service: name=uchiwa state=restarted

- name: restart nginx service
  service: name=nginx state=restarted

从运行来看，client.json 已经发生改变，但我从未看到调用处理程序的通知。

答案1

首先，由于文件类型错误，我猜你的处理程序会被忽略：

角色/sensu/处理程序/主页面

应该：roles/sensu/handlers/main.yml

其次，请注意，尽管您有几个处理程序，但唯一被通知程序通知的处理程序是：restart sensu client。因此其他处理程序将不会运行。

处理程序是任务列表，与常规任务并无太大区别，它们由全局唯一名称引用。处理程序是通知程序所通知的对象。如果没有通知处理程序，处理程序将不会运行。无论有多少通知处理程序，处理程序都只会运行一次，即在特定剧集中的所有任务完成后。
