用ansible主控机控制debian12和centos8安装apache

在Ansible中，你可以使用YAML语法创建一个Playbook来从主控机控制Debian 12和CentOS 8上的Apache安装。以下是一个基本示例：

---
- name: Install Apache on Debian and CentOS
  hosts: all
  become: true
  vars:
    os_family: "!"
  tasks:
  - name: Conditionally install Apache based on OS
    when: ansible_os_family == 'Debian'
    apt:
      name: apache2
      state: present

  - name: Conditionally install Apache based on OS (CentOS)
    when: ansible_os_family == 'RedHat'
    yum:
      name: httpd
      state: present

  - name: Restart Apache service if installed
    service:
      name: "{{ 'apache2' if ansible_os_family == 'Debian' else 'httpd' }}"
      state: restarted
    notify: restart_service

  handlers:
  - name: restart_service
    service:
      name: "{{ 'apache2' if ansible_os_family == 'Debian' else 'httpd' }}"
      state: restarted

  - name: Notify the success message
    debug:
      msg: Apache has been successfully installed.

# 如果需要在playbook中加入对应平台的额外步骤，可以在tasks中添加更多的when条件

在这个Playbook中，我们首先检查主机的操作系统家族，然后根据是Debian还是CentOS执行相应的包管理命令（apt或yum），并确保服务重启。`handlers`部分定义了当服务状态改变时执行的动作。
