Question

我有这个简单的apache角色（在CentOS7中）：

角色/阿帕奇/任务/ main.yml

---
- name: Add epel-release repo
  yum:
    name: epel-release
    state: present

- name: Install Apache2
  yum:
    name: httpd
    state: present

- name: Insert Index Page
  copy:
    src: index.html
    dest: /var/www/html/index.html

角色/阿帕奇/处理/ main.yml

---
- name: Start Apache
  service: name=httpd state=started

- name: verify that the web service is running
  command: systemctl status httpd
  register: status_result

- name: debug
  debug: var=status_result

with-roles.yml - playbook与＆＃39;角色相同的水平＆＃39;目录

---
- name: Install apache2 in CentOS 7
  hosts: 1.23.4.56
  become: true
  roles:
    - apache

然后按照以下方式运行剧本：

$ ansible-playbook -u root --private-key ~/.ssh/this_key.ppk with-roles.yml -i "1.23.4.56" -vvvv

这是屏幕上详细输出的尾端部分：

    ...
    ...
    "mode": "0644", 
    "owner": "root", 
    "path": "/var/www/html/index.html", 
    "size": 11, 
    "state": "file", 
    "uid": 0
}
META: ran handlers
META: ran handlers

PLAY RECAP *******************************************************************************************************************
1.23.4.56              : ok=4    changed=0    unreachable=0    failed=0

但是当我登录到1.23.4.56时，机器已安装httpd但已停止（这意味着处理程序没有运行）。我做错了什么？

Answer 1

处理程序仅在收到通知时执行。

Answer 2

根据RenéPijl的提示，答案结果显示在https://serverfault.com/questions/617548/always-trigger-handler-execution-in-ansible。

具体来说，我不得不将其添加到 roles / apache / tasks / main.yml 的底部

...
...
- name: Apache Starter
  command: /bin/true
  notify: Start Apache

ansible角色无法通过处理程序启动apache
