+# Transfer模块部署文档
+
+## 部署概述
+
+Transfer模块是一个完整的资金划转解决方案，支持农场内部模式和外部API模式。本文档详细说明了模块的部署、配置和维护流程。
+
+## 系统要求
+
+### 基础环境
+- PHP >= 8.1
+- Laravel >= 9.0
+- MySQL >= 8.0
+- Redis >= 6.0（用于队列和缓存）
+
+### 扩展要求
+- BCMath扩展（高精度数学计算）
+- cURL扩展（外部API调用）
+- JSON扩展（数据序列化）
+
+### 依赖模块
+- Fund模块（资金管理）
+- OpenAPI模块（对外接口，可选）
+
+## 部署步骤
+
+### 1. 数据库部署
+
+#### 1.1 执行建表SQL
+```bash
+# 连接到MySQL数据库
+mysql -u username -p database_name
+
+# 执行建表SQL
+source app/Module/Transfer/Database/transfer_tables.sql
+```
+
+#### 1.2 执行初始化数据
+```bash
+# 执行初始化数据SQL
+source app/Module/Transfer/Database/transfer_init_data.sql
+```
+
+#### 1.3 创建性能索引
+```bash
+# 执行性能优化SQL
+source app/Module/Transfer/Database/optimization.sql
+```
+
+### 2. 配置文件部署
+
+#### 2.1 发布配置文件
+```bash
+# 发布Transfer配置文件
+php artisan vendor:publish --tag=transfer-config
+```
+
+#### 2.2 配置环境变量
+在 `.env` 文件中添加：
+```env
+# Transfer模块配置
+TRANSFER_DEBUG=false
+TRANSFER_API_TIMEOUT=30
+TRANSFER_QUEUE_CONNECTION=redis
+TRANSFER_CACHE_DRIVER=redis
+```
+
+#### 2.3 修改配置文件
+编辑 `config/transfer.php`：
+```php
+// 根据生产环境需求调整配置
+'api' => [
+    'timeout' => env('TRANSFER_API_TIMEOUT', 30),
+    'retry_times' => 3,
+],
+
+'queue' => [
+    'default' => env('TRANSFER_QUEUE_CONNECTION', 'redis'),
+],
+```
+
+### 3. 队列配置
+
+#### 3.1 配置队列驱动
+在 `config/queue.php` 中确保Redis配置正确：
+```php
+'connections' => [
+    'redis' => [
+        'driver' => 'redis',
+        'connection' => 'default',
+        'queue' => env('REDIS_QUEUE', 'default'),
+        'retry_after' => 90,
+        'block_for' => null,
+    ],
+],
+```
+
+#### 3.2 启动队列工作进程
+```bash
+# 启动Transfer队列工作进程
+php artisan queue:work redis --queue=transfer,transfer_callback --sleep=3 --tries=3 --max-time=3600
+
+# 使用Supervisor管理队列进程（推荐）
+# 创建 /etc/supervisor/conf.d/transfer-worker.conf
+```
+
+Supervisor配置示例：
+```ini
+[program:transfer-worker]
+process_name=%(program_name)s_%(process_num)02d
+command=php /path/to/artisan queue:work redis --queue=transfer,transfer_callback --sleep=3 --tries=3 --max-time=3600
+directory=/path/to/project
+autostart=true
+autorestart=true
+user=www-data
+numprocs=2
+redirect_stderr=true
+stdout_logfile=/var/log/transfer-worker.log
+stopwaitsecs=3600
+```
+
+### 4. 定时任务配置
+
+#### 4.1 添加Cron任务
+```bash
+# 编辑crontab
+crontab -e
+
+# 添加以下任务
+# Transfer订单处理（每5分钟）
+*/5 * * * * cd /path/to/project && php artisan transfer:process --type=orders --limit=100 >> /dev/null 2>&1
+
+# Transfer回调处理（每2分钟）
+*/2 * * * * cd /path/to/project && php artisan transfer:process --type=callbacks --limit=50 >> /dev/null 2>&1
+
+# 每日统计报告（每天凌晨1点）
+0 1 * * * cd /path/to/project && php artisan transfer:stats --period=yesterday --export=/var/log/transfer-daily-stats.csv >> /dev/null 2>&1
+```
+
+### 5. 权限配置
+
+#### 5.1 文件权限
+```bash
+# 设置正确的文件权限
+chown -R www-data:www-data /path/to/project/storage
+chown -R www-data:www-data /path/to/project/bootstrap/cache
+chmod -R 755 /path/to/project/storage
+chmod -R 755 /path/to/project/bootstrap/cache
+```
+
+#### 5.2 日志目录权限
+```bash
+# 创建Transfer日志目录
+mkdir -p /var/log/transfer
+chown www-data:www-data /var/log/transfer
+chmod 755 /var/log/transfer
+```
+
+## 配置说明
+
+### 1. 应用配置
+
+#### 1.1 农场内部模式
+适用于纯内部资金流转，无需外部API：
+```php
+// 所有API URL留空即为农场内部模式
+'order_callback_url' => null,
+'order_in_info_url' => null,
+'order_out_create_url' => null,
+'order_out_info_url' => null,
+```
+
+#### 1.2 外部API模式
+适用于与外部系统对接：
+```php
+// 配置相应的API端点
+'order_callback_url' => 'https://external-api.com/callback',
+'order_out_create_url' => 'https://external-api.com/transfer/create',
+'order_out_info_url' => 'https://external-api.com/transfer/info',
+```
+
+### 2. 安全配置
+
+#### 2.1 API签名验证
+```php
+'security' => [
+    'signature_verification' => true,
+    'signature_method' => 'md5',
+],
+```
+
+#### 2.2 IP白名单（可选）
+```php
+'security' => [
+    'ip_whitelist_enabled' => true,
+    'ip_whitelist' => [
+        '192.168.1.100',
+        '10.0.0.50',
+    ],
+],
+```
+
+### 3. 性能配置
+
+#### 3.1 缓存配置
+```php
+'cache' => [
+    'enabled' => true,
+    'app_config_ttl' => 3600,
+    'stats_ttl' => 300,
+],
+```
+
+#### 3.2 队列配置
+```php
+'queue' => [
+    'max_tries' => 3,
+    'timeout' => 120,
+    'failed_job_retention' => 86400,
+],
+```
+
+## 监控和维护
+
+### 1. 日志监控
+
+#### 1.1 应用日志
+```bash
+# 查看Transfer模块日志
+tail -f storage/logs/laravel.log | grep Transfer
+
+# 查看队列日志
+tail -f /var/log/transfer-worker.log
+```
+
+#### 1.2 数据库日志
+```bash
+# 查看慢查询日志
+tail -f /var/log/mysql/slow.log | grep transfer
+```
+
+### 2. 性能监控
+
+#### 2.1 队列监控
+```bash
+# 查看队列状态
+php artisan queue:monitor redis:transfer,redis:transfer_callback
+
+# 查看失败任务
+php artisan queue:failed
+```
+
+#### 2.2 数据库监控
+```sql
+-- 查看表大小
+SELECT 
+    TABLE_NAME,
+    ROUND(((DATA_LENGTH + INDEX_LENGTH) / 1024 / 1024), 2) AS 'Size (MB)',
+    TABLE_ROWS
+FROM information_schema.TABLES 
+WHERE TABLE_NAME LIKE 'kku_transfer_%';
+
+-- 查看索引使用情况
+SHOW INDEX FROM kku_transfer_orders;
+```
+
+### 3. 健康检查
+
+#### 3.1 创建健康检查脚本
+```bash
+#!/bin/bash
+# transfer-health-check.sh
+
+# 检查数据库连接
+php artisan tinker --execute="DB::connection()->getPdo();"
+
+# 检查队列工作进程
+ps aux | grep "queue:work" | grep -v grep
+
+# 检查Redis连接
+redis-cli ping
+
+# 检查最近的订单处理情况
+php artisan transfer:stats --period=today
+```
+
+#### 3.2 设置监控告警
+```bash
+# 添加到crontab，每10分钟检查一次
+*/10 * * * * /path/to/transfer-health-check.sh || echo "Transfer health check failed" | mail -s "Transfer Alert" admin@example.com
+```
+
+## 故障排除
+
+### 1. 常见问题
+
+#### 1.1 队列任务失败
+```bash
+# 查看失败任务详情
+php artisan queue:failed
+
+# 重试失败任务
+php artisan queue:retry all
+
+# 清除失败任务
+php artisan queue:flush
+```
+
+#### 1.2 外部API调用失败
+```bash
+# 检查网络连接
+curl -I https://external-api.com/health
+
+# 查看API调用日志
+grep "ExternalApiService" storage/logs/laravel.log
+```
+
+#### 1.3 数据库性能问题
+```sql
+-- 查看正在执行的查询
+SHOW PROCESSLIST;
+
+-- 查看锁等待情况
+SELECT * FROM information_schema.INNODB_LOCKS;
+
+-- 优化表
+OPTIMIZE TABLE kku_transfer_orders;
+```
+
+### 2. 紧急恢复
+
+#### 2.1 数据备份恢复
+```bash
+# 恢复数据库备份
+mysql -u username -p database_name < transfer_backup.sql
+```
+
+#### 2.2 服务重启
+```bash
+# 重启队列工作进程
+supervisorctl restart transfer-worker:*
+
+# 重启Web服务
+systemctl restart nginx
+systemctl restart php8.1-fpm
+```
+
+## 升级指南
+
+### 1. 版本升级步骤
+1. 备份数据库和配置文件
+2. 停止队列工作进程
+3. 更新代码
+4. 执行数据库迁移（如有）
+5. 更新配置文件
+6. 重启服务
+7. 验证功能正常
+
+### 2. 兼容性检查
+- 检查PHP版本兼容性
+- 检查依赖模块版本
+- 验证API接口兼容性
+- 测试核心功能
+
+## 安全建议
+
+1. **定期更新密钥**：定期更换API签名密钥
+2. **访问控制**：限制后台管理访问IP
+3. **数据加密**：敏感数据传输使用HTTPS
+4. **审计日志**：保留详细的操作日志
+5. **权限最小化**：数据库用户权限最小化
