微服务应用

场景2：微服务应用

适合：大型项目、分布式系统、高并发场景

步骤1：准备中间件

使用 Docker Compose 启动必需的中间件：

创建 docker-compose.yml：

version: '3.8'

services:
  # MySQL
  mysql:
    image: mysql:8.0
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: demo
    volumes:
      - mysql-data:/var/lib/mysql

  # Redis
  redis:
    image: redis:7.0
    ports:
      - "6379:6379"

  # RabbitMQ
  rabbitmq:
    image: rabbitmq:3.12-management
    ports:
      - "5672:5672"
      - "15672:15672"
    environment:
      RABBITMQ_DEFAULT_USER: guest
      RABBITMQ_DEFAULT_PASS: guest

  # Nacos
  nacos:
    image: nacos/nacos-server:v2.3.0
    ports:
      - "8848:8848"
    environment:
      MODE: standalone

volumes:
  mysql-data:

启动中间件：

```bash docker-compose up -d
