Ansible实验部署Nginx与PostgreSQL后如何配置Nginx重启跳转google.com

原有Playbook问题修正 #

你当前的代码存在YAML缩进错误、重复安装任务的问题，优化后的基础安装+服务保活逻辑如下，首先整合冗余任务，补全开机自启配置：

- name: 'Install and start Nginx & PostgreSQL'
  hosts: localhost
  connection: local
  become: yes
  become_method: sudo
  tasks:
    - name: Install required packages
      apt: 
        name: "{{ item }}" 
        state: latest
        update_cache: yes
      loop:
        - nginx
        - postgresql

    - name: Start and enable Nginx service
      service:
        name: nginx
        state: started
        enabled: yes

    - name: Start and enable PostgreSQL service
      service:
        name: postgresql
        state: started
        enabled: yes

新增Nginx自动跳转google.com配置 #

要实现Nginx重启后依然自动跳转，需要修改Nginx默认站点配置，添加永久重定向规则，在上述Playbook的tasks中新增以下内容即可：

- name: Configure Nginx redirect to google.com
      copy:
        content: |
          server {
              listen 80 default_server;
              listen [::]:80 default_server;
              root /var/www/html;
              index index.html index.htm;
              server_name _;
              location / {
                  return 301 https://www.google.com$request_uri;
              }
          }
        dest: /etc/nginx/sites-available/default
        mode: '0644'
      notify: Restart Nginx

  handlers:
    - name: Restart Nginx
      service:
        name: nginx
        state: restarted

校验注意事项 #

• 确保重定向规则返回码为301，符合实验校验要求
• 配置修改后通过handler触发Nginx重启，避免手动操作导致的规则失效
• 补全了enabled: yes参数，确保服务器重启后两个服务都会自动拉起
