+# 数据库配置指南
+
+## 数据库配置信息
+
+### 腾讯云MySQL配置
+- **主机地址**: nj-cdb-3pwh2kz1.sql.tencentcdb.com
+- **端口**: 20784
+- **数据库名**: xumgdata
+- **用户名**: xymg
+- **密码**: aiot741$xymg
+
+### 当前状态
+🔴 **连接状态**: 访问受限（IP白名单问题）
+📍 **当前IP**: 43.153.101.71（需要添加到白名单）
+
+## 解决IP白名单问题
+
+### 步骤1：登录腾讯云控制台
+1. 访问 [腾讯云控制台](https://console.cloud.tencent.com/)
+2. 登录账户
+
+### 步骤2：找到数据库实例
+1. 进入 **云数据库 MySQL** 控制台
+2. 找到实例：`nj-cdb-3pwh2kz1`
+
+### 步骤3：配置安全组/白名单
+1. 点击实例进入详情页
+2. 找到 **安全组** 或 **白名单** 设置
+3. 添加以下IP地址：
+   - `43.153.101.71` （当前开发服务器IP）
+   - `0.0.0.0/0` （临时开放所有IP，生产环境不推荐）
+
+### 步骤4：验证连接
+执行以下命令测试连接：
+```bash
+cd /Users/ainongkeji/code/vue/xlxumu/backend/database
+node database-manager.js test
+```
+
+## 数据库初始化
+
+### 一键初始化
+```bash
+# 测试连接
+node database-manager.js test
+
+# 初始化数据库表结构
+node database-manager.js init
+
+# 重置数据库（删除所有数据后重新创建）
+node database-manager.js reset
+```
+
+### 手动初始化
+如果自动化工具无法使用，可以手动执行SQL脚本：
+
+1. **连接数据库**：
+   ```bash
+   mysql -h nj-cdb-3pwh2kz1.sql.tencentcdb.com -P 20784 -u xymg -p xumgdata
+   ```
+
+2. **执行表结构脚本**：
+   ```sql
+   source /Users/ainongkeji/code/vue/xlxumu/backend/database/init_tables.sql;
+   ```
+
+3. **执行初始数据脚本**：
+   ```sql
+   source /Users/ainongkeji/code/vue/xlxumu/backend/database/init_data.sql;
+   ```
+
+## 数据库表结构
+
+### 核心业务表（21张）
+
+#### 1. 用户权限模块
+- `users` - 用户表
+- `roles` - 角色表
+- `permissions` - 权限表
+- `user_roles` - 用户角色关联表

+
+#### 2. 牛只档案模块
+- `cattle` - 牛只档案表
+- `feeding_records` - 饲养记录表
+- `breeding_records` - 繁殖记录表
+
+#### 3. 金融业务模块
+- `loan_applications` - 贷款申请表
+- `insurance_applications` - 保险申请表
+- `claims` - 理赔申请表
+
+#### 4. 交易管理模块
+- `transactions` - 交易记录表
+- `contracts` - 合同表
+
+#### 5. 政府监管模块
+- `farms` - 牧场注册表
+- `government_inspections` - 政府检查记录表
+- `policies` - 政策法规表
+
+#### 6. 商城管理模块
+- `products` - 商品表
+- `orders` - 订单表
+- `order_items` - 订单商品表
+- `product_reviews` - 商品评价表
+
+#### 7. 质量追溯模块
+- `product_traceability` - 产品追溯表
+
+#### 8. 系统管理模块
+- `operation_logs` - 操作日志表
+
+## 初始数据说明
+
+### 默认用户账户
+| 用户名 | 密码 | 角色 | 姓名 | 描述 |
+|--------|------|------|------|------|
+| admin | 123456 | 系统管理员 | 系统管理员 | 拥有所有权限 |
+| farmer001 | 123456 | 养殖户 | 张三 | 测试养殖户1 |
+| farmer002 | 123456 | 养殖户 | 李四 | 测试养殖户2 |
+| banker001 | 123456 | 银行职员 | 王五 | 测试银行职员 |
+| insurer001 | 123456 | 保险员 | 赵六 | 测试保险员 |
+| inspector001 | 123456 | 政府检查员 | 钱七 | 测试政府检查员 |
+| trader001 | 123456 | 交易员 | 孙八 | 测试交易员 |
+| merchant001 | 123456 | 商户 | 周九 | 测试商户 |
+
+### 角色权限配置
+- **管理员**: 拥有所有权限
+- **养殖户**: 牛只管理、金融申请、交易参与
+- **银行职员**: 贷款审核和管理
+- **保险员**: 保险审核和理赔管理
+- **政府检查员**: 监管检查和质量追溯
+- **政府管理员**: 监管数据统计和政策管理
+- **交易员**: 交易和合同管理
+- **商户**: 商品和订单管理
+
+### 示例数据
+- **3个示例牧场**：锡林浩特市第一牧场、东乌旗生态牧场、西乌旗示范牧场
+- **5头示例牛只**：包含不同品种和基本信息
+- **5个示例商品**：牛肉、乳制品、肉制品等
+
+## 验证安装
+
+### 1. 检查表创建
+```sql
+SELECT TABLE_NAME, TABLE_COMMENT 
+FROM information_schema.TABLES 
+WHERE TABLE_SCHEMA = 'xumgdata' 
+ORDER BY TABLE_NAME;
+```
+
+### 2. 检查数据插入
+```sql
+-- 检查角色数量
+SELECT COUNT(*) as role_count FROM roles;
+
+-- 检查权限数量  
+SELECT COUNT(*) as permission_count FROM permissions;
+
+-- 检查用户数量
+SELECT COUNT(*) as user_count FROM users;
+
+-- 检查管理员用户
+SELECT username, real_name, user_type FROM users WHERE user_type = 'admin';
+```
+
+### 3. 测试API连接
+启动API服务器后，访问：
+```
+http://localhost:8889/health
+http://localhost:8889/api/v1/database/status
+```
+
+## 故障排除
+
+### 常见错误
+
+#### 1. Access denied for user
+**错误**: `Access denied for user 'xymg'@'43.153.101.71'`
+**解决**: 检查IP白名单设置
+
+#### 2. Can't connect to MySQL server
+**错误**: `Can't connect to MySQL server`
+**解决**: 检查网络连接和端口访问
+
+#### 3. Unknown database
+**错误**: `Unknown database 'xumgdata'`
+**解决**: 确认数据库名称正确
+
+#### 4. Table already exists
+**错误**: `Table 'xxx' already exists`
+**解决**: 正常情况，使用 `CREATE TABLE IF NOT EXISTS`
+
+### 联系支持
+如遇到问题，请检查：
+1. 网络连接是否正常
+2. 腾讯云账户状态
+3. 数据库实例状态
+4. IP白名单配置
+
+## 生产环境注意事项
+
+### 安全配置
+1. **修改默认密码**: 所有测试账户密码
+2. **限制IP访问**: 仅允许必要的IP访问
+3. **启用SSL**: 加密数据传输
+4. **定期备份**: 设置自动备份策略
+
+### 性能优化
+1. **索引优化**: 根据查询模式优化索引
+2. **分区表**: 对大数据量表进行分区
+3. **连接池**: 优化数据库连接池配置
+4. **监控**: 设置性能监控和告警
+
+### 运维管理
+1. **日志管理**: 配置慢查询日志
+2. **权限管理**: 定期审查用户权限
+3. **版本管理**: 使用数据库迁移工具
+4. **容灾**: 配置主从复制和故障转移
