本文介绍了使用Ansible进行自动化部署的四个实例，包括创建用户、复制文件、配置防火墙及安装服务。通过这些示例，读者可以了解如何利用Ansible简化日常运维任务。

示例1：创建用户

---
- name: create user
  hosts: openstack
  gather_facts: false
  tasks:
  - name: create {{ item }}
    user: 
      name: "{{ item }}"
      groups: wheel
      password: "{{ 123456 | password_hash('sha512', 'mysecretsalt') }}"
    loop:
    - alex
    - jack

示例2：复制文件

---
- name: copy file
  hosts: servera
  tasks:
  - name: copy ansible.cfg file
    copy:
      src: /root/ansible.cfg
      dest: /opt/ansible.cfg
      mode: '0644'

示例3：配置防火墙

---
- name: add firewall rule
  hosts: servera
  tasks:
  - name: add http service
    firewalld:
      service: http
      state: enabled
      permanent: true
      immediate: true
  - name: add tcp 8080
    firewalld:
      port: 8080/tcp
      state: enabled
      permanent: true
      immediate: true

示例4：安装服务

---
- name: install nginx
  hosts: servera
  tasks:
  - name: install nginx
    package:
      name: nginx
      state: present
  - name: enable service
    service:
      name: nginx
      enabled: true
      state: started
