+
+## 当前部署状态
+
+### 服务器部署方式
+当前使用 **Docker** 容器部署，包含两个容器：
+
+| 容器名称 | 服务 | 端口 | 状态 |
+|---------|------|------|------|
+| `quanyixiaozhushou-app` | Node.js 后端 | 3000 | 运行中 |
+| `quanyixiaozhushou-mongo` | MongoDB 7.0 | 27018 | 运行中 |
+
+```bash
+# 查看容器状态
+docker ps
+
+# 查看后端日志
+docker logs quanyixiaozhushou-app
+
+# 查看 MongoDB 日志
+docker logs quanyixiaozhushou-mongo
+```
+
+### 环境变量 (生产环境)
+```env
+PORT=3000
+NODE_ENV=production
+WECHAT_APPID=wxa83262674846ca1a
+WECHAT_APPSECRET=c40e9d356438f92d10091a115ee50172
+MONGODB_URI=mongodb://localhost:27017/quanyixiaozhushou
+JWT_SECRET=your_jwt_secret_key_here_change_in_production
+JWT_EXPIRES_IN=7d
+LOG_LEVEL=info
+```
+
+## CI/CD 流程设计
+
+### 1. Git 工作流
+
+```
+[Developer] → feature branch → Pull Request → [Code Review] → merge to master → [CI/CD Pipeline] → Deploy
+```
+
+### 2. 分支策略
+
+| 分支 | 用途 | 保护规则 |
+|------|------|----------|
+| master | 生产环境分支 | 禁止直接推送，需 PR |
+| develop | 开发环境分支 | 需 PR |
+| feature/* | 功能开发 | 自由推送 |
+| hotfix/* | 紧急修复 | 需 PR 到 master |
+
+### 3. CI/CD Pipeline 流程
+
+```mermaid
+graph TD
+    A[Git Push/PR] --> B[Checkout Code]
+    B --> C[Install Dependencies]
+    C --> D[Run Tests]
+    D --> E[Lint Check]
+    E --> F[Build Docker Image]
+    F --> G[Push to Registry]
+    G --> H[Deploy to Server]
+    H --> I[Health Check]
+    I --> J[Notify]
+```
+
+## 详细 CI/CD 配置
+
+### Stage 1: 代码检出 (Checkout)
+
+```yaml

+    branches: [ master, develop ]
+  pull_request:
+    branches: [ master ]
+
+jobs:
+  build-and-deploy:
+    runs-on: ubuntu-latest
+    
+    steps:
+    - name: Checkout code
+      uses: actions/checkout@v4
+      with:
+        repository: https://git.dxz99wyr.cn/Superuser/miniapp-api

+```
+
+### Stage 2: 依赖安装与测试
+
+```yaml

+
+### Stage 3: Docker 构建
+
+```yaml

+```
+
+### Stage 4: 部署到服务器
+
+```yaml
+    - name: Deploy to server
+      uses: appleboy/ssh-action@v1.0.0
+      with:

+
+## 部署脚本 (服务器端)
+
+### 1. 初始化脚本 (首次部署)
+
+```bash
+#!/bin/bash
+# deploy-init.sh
+
+set -e
+
+PROJECT_DIR="/var/www/quanyixiaozhushou-app"
+BACKUP_DIR="/var/backups/quanyixiaozhushou"
+
+# 创建目录
+mkdir -p $PROJECT_DIR
+mkdir -p $BACKUP_DIR
+mkdir -p $PROJECT_DIR/public/uploads
+mkdir -p $PROJECT_DIR/public/avatars
+
+# 安装 Docker (如果未安装)
+if ! command -v docker &> /dev/null; then
+    curl -fsSL https://get.docker.com | sh
+    systemctl enable docker
+    systemctl start docker
+fi
+
+# 安装 Docker Compose
+if ! command -v docker-compose &> /dev/null; then
+    curl -L "https://github.com/docker/compose/releases/download/v2.23.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
+    chmod +x /usr/local/bin/docker-compose
+fi
+
+echo "初始化完成"
+```
+
+### 2. 部署脚本 (日常更新)
+
+```bash
+#!/bin/bash
+# deploy.sh
+
+set -e
+
+IMAGE_TAG=${1:-latest}
+PROJECT_DIR="/var/www/quanyixiaozhushou-app"
+BACKUP_DIR="/var/backups/quanyixiaozhushou"
+TIMESTAMP=$(date +%Y%m%d_%H%M%S)
+
+echo "=== 开始部署 ==="
+echo "镜像标签: $IMAGE_TAG"
+
+# 1. 备份当前数据
+echo "[1/5] 备份当前数据..."
+mkdir -p $BACKUP_DIR/$TIMESTAMP
+cp -r $PROJECT_DIR/public/uploads $BACKUP_DIR/$TIMESTAMP/ 2>/dev/null || true
+mongodump --db quanyixiaozhushou --out $BACKUP_DIR/$TIMESTAMP/ 2>/dev/null || true
+
+# 2. 拉取最新镜像
+echo "[2/5] 拉取最新镜像..."
+docker pull ghcr.io/your-repo/quanyixiaozhushou-backend:$IMAGE_TAG
+
+# 3. 停止旧容器
+echo "[3/5] 停止旧容器..."
+docker stop quanyi-backend 2>/dev/null || true
+docker rm quanyi-backend 2>/dev/null || true
+
+# 4. 启动新容器
+echo "[4/5] 启动新容器..."
+docker run -d \
+  --name quanyi-backend \
+  --restart unless-stopped \
+  -p 3000:3000 \
+  -e PORT=3000 \
+  -e NODE_ENV=production \
+  -e WECHAT_APPID=$WECHAT_APPID \
+  -e WECHAT_APPSECRET=$WECHAT_APPSECRET \
+  -e MONGODB_URI=$MONGODB_URI \
+  -e JWT_SECRET=$JWT_SECRET \
+  -v $PROJECT_DIR/public/uploads:/app/public/uploads \
+  -v $PROJECT_DIR/public/avatars:/app/public/avatars \
+  ghcr.io/your-repo/quanyixiaozhushou-backend:$IMAGE_TAG
+
+# 5. 健康检查
+echo "[5/5] 健康检查..."
+sleep 5
+
+MAX_RETRIES=10
+RETRY_COUNT=0
+
+while [ $RETRY_COUNT -lt $MAX_RETRIES ]; do
+  if curl -f -s http://localhost:3000/health > /dev/null; then
+    echo "✅ 服务健康检查通过"
+    break
+  fi
+  
+  RETRY_COUNT=$((RETRY_COUNT + 1))
+  echo "等待服务启动... ($RETRY_COUNT/$MAX_RETRIES)"
+  sleep 3
+done
+
+if [ $RETRY_COUNT -eq $MAX_RETRIES ]; then
+  echo "❌ 健康检查失败，执行回滚..."
+  # 回滚逻辑
+  docker stop quanyi-backend
+  docker rm quanyi-backend
+  # 启动上一个版本
+  exit 1
+fi
+
+# 清理旧镜像
+docker image prune -f
+
+echo "=== 部署完成 ==="
+echo "备份位置: $BACKUP_DIR/$TIMESTAMP"
+```
+
+## 健康检查端点
+
+确保后端有以下健康检查端点：
+
+```javascript
+// src/app.js
+app.get('/health', (req, res) => {
+  res.status(200).json({
+    status: 'ok',
+    timestamp: new Date().toISOString(),
+    version: process.env.npm_package_version || '1.0.0'
+  });
+});
+```
+
+## 微信小程序 CI/CD
+
+### 自动上传脚本
+
+```yaml
+# .github/workflows/miniapp-deploy.yml
+name: Miniapp Deploy
+
+on:
+  push:
+    branches: [ master ]
+    paths:

+          --enable-es6 true
+```
+
+## 监控与告警
+
+### 1. 日志监控
+
+```bash
+# 查看实时日志
+docker logs -f quanyi-backend
+
+# 查看错误日志
+docker logs quanyi-backend 2>&1 | grep ERROR
+```
+
+### 进程监控
+
+```bash
+# Docker 容器监控
+docker stats quanyixiaozhushou-app
+
+# 进入容器调试
+docker exec -it quanyixiaozhushou-app sh
+```
+
+### 3. 告警规则
+
+- 服务 5xx 错误率 > 1%
+- 响应时间 > 2s
+- 内存使用 > 80%
+- CPU 使用 > 80%
+- 磁盘使用 > 85%
+
+## 回滚策略
+
+### 自动回滚条件
+
+- 健康检查失败
+- 错误率突增
+- 部署后 5 分钟内服务不可用
+
+### 回滚脚本
+
+```bash
+#!/bin/bash
+# rollback.sh
+
+PREVIOUS_IMAGE=$(docker images --format "{{.Repository}}:{{.Tag}}" | grep quanyixiaozhushou-backend | head -2 | tail -1)
+
+echo "回滚到上一个版本: $PREVIOUS_IMAGE"
+
+docker stop quanyi-backend
+docker rm quanyi-backend
+docker run -d \
+  --name quanyi-backend \
+  --restart unless-stopped \
+  -p 3000:3000 \
+  -e PORT=3000 \
+  -e NODE_ENV=production \
+  -v /var/www/quanyixiaozhushou-app/public/uploads:/app/public/uploads \
+  $PREVIOUS_IMAGE
+
+echo "回滚完成"
+```
+
+## 数据库迁移
+
+### MongoDB 迁移脚本
+
+```javascript
+// migrations/001_add_subscription_type.js
+const mongoose = require('mongoose');
+
+async function migrate() {
+  await mongoose.connect(process.env.MONGODB_URI);
+  
+  // 添加 type 字段到现有订阅记录
+  await mongoose.connection.collection('usersubscriptions').updateMany(
+    { type: { $exists: false } },
+    { $set: { type: 'version-update' } }
+  );
+  
+  console.log('Migration completed');
+  process.exit(0);
+}
+
+migrate().catch(console.error);
+```
+
+## 安全检查清单
