ansible playbook 单节点商城

好的，我可以为您提供一些关于使用 Ansible Playbook 部署单节点商城的指导。

首先，您需要编写一个 Playbook 文件，其中包括以下步骤：

1. 安装必要的软件包，如 Java、MySQL、Nginx 等。
2. 下载并编译商城源代码。
3. 配置商城所需的环境变量，如数据库连接信息、端口号等。
4. 配置 Nginx 代理商城服务，使其可以通过 Web 页面访问。
5. 启动商城服务。

以下是一个简单的 Playbook 示例，可以帮助您了解如何编写 Ansible Playbook：

---
- name: Deploy Single-Node Online Store
  hosts: your_server_hostname
  
  vars:
    mysql_root_password: your_mysql_root_password
    mysql_user: your_mysql_username
    mysql_password: your_mysql_password
    mysql_database: your_mysql_database_name
    online_store_port: 8080
  
  tasks:
    - name: Install Java
      apt:
        name: openjdk-8-jdk
        state: present
        
    - name: Install MySQL
      apt:
        name: mysql-server
        state: present
      vars:
        mysql_root_password: "{{ mysql_root_password }}"
      become: true
      
    - name: Create MySQL Database
      mysql_db:
        name: "{{ mysql_database }}"
        state: present
        login_user: root
        login_password: "{{ mysql_root_password }}"
        
    - name: Create MySQL User
      mysql_user:
        name: "{{ mysql_user }}"
        password: "{{ mysql_password }}"
        priv: "{{ mysql_database }}.*:ALL"
        state: present
        login_user: root
        login_password: "{{ mysql_root_password }}"
        
    - name: Download and Compile Online Store Source Code
      git:
        repo: https://github.com/your_online_store_repo.git
        dest: /opt/online_store
      become: true
      
    - name: Set Online Store Environment Variables
      lineinfile:
        path: /opt/online_store/.env
        regexp: "{{ item.regexp }}"
        line: "{{ item.line }}"
      with_items:
        - { regexp: '^DB_HOST=', line: 'DB_HOST=localhost' }
        - { regexp: '^DB_PORT=', line: 'DB_PORT=3306' }
        - { regexp: '^DB_DATABASE=', line: 'DB_DATABASE={{ mysql_database }}' }
        - { regexp: '^DB_USERNAME=', line: 'DB_USERNAME={{ mysql_user }}' }
        - { regexp: '^DB_PASSWORD=', line: 'DB_PASSWORD={{ mysql_password }}' }
        - { regexp: '^APP_URL=', line: 'APP_URL=http://localhost:{{ online_store_port }}' }
        - { regexp: '^APP_PORT=', line: 'APP_PORT={{ online_store_port }}' }
      become: true
      
    - name: Configure Nginx
      template:
        src: nginx.conf.j2
        dest: /etc/nginx/sites-available/online_store
      become: true
      
    - name: Enable Nginx Site
      file:
        src: /etc/nginx/sites-available/online_store
        dest: /etc/nginx/sites-enabled/online_store
        state: link
        
    - name: Start Online Store Service
      command: npm run start
      args:
        chdir: /opt/online_store
      become: true
