+# 用户认证系统部署指南
+
+## 📋 概述
+
+本文档描述如何在 Ubuntu 服务器上部署 ViGent2 用户认证系统。
+
+| 组件 | 技术 | 说明 |
+|------|------|------|
+| 数据库 | Supabase (PostgreSQL) | 云端免费版 |
+| 认证 | FastAPI + JWT | HttpOnly Cookie |
+| 密码 | bcrypt | 单向哈希 |
+
+---
+
+## 步骤 1: 配置 Supabase
+
+### 1.1 创建项目
+
+1. 访问 [supabase.com](https://supabase.com)
+2. 创建免费项目
+3. 记录以下信息：
+   - **Project URL**: `https://xxx.supabase.co`
+   - **anon public key**: `eyJhbGciOiJIUzI1NiIs...`
+
+### 1.2 创建数据库表
+
+1. 进入 **SQL Editor**
+2. 执行以下 SQL：
+
+```sql
+-- 1. 创建 users 表
+CREATE TABLE IF NOT EXISTS users (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    email TEXT UNIQUE NOT NULL,
+    password_hash TEXT NOT NULL,
+    username TEXT,
+    role TEXT DEFAULT 'pending' CHECK (role IN ('pending', 'user', 'admin')),
+    is_active BOOLEAN DEFAULT FALSE,
+    expires_at TIMESTAMP WITH TIME ZONE,
+    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
+    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
+);
+
+-- 2. 创建 user_sessions 表
+CREATE TABLE IF NOT EXISTS user_sessions (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    user_id UUID REFERENCES users(id) ON DELETE CASCADE UNIQUE,
+    session_token TEXT UNIQUE NOT NULL,
+    device_info TEXT,
+    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
+);
+
+-- 3. 创建 social_accounts 表
+CREATE TABLE IF NOT EXISTS social_accounts (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    user_id UUID REFERENCES users(id) ON DELETE CASCADE,
+    platform TEXT NOT NULL CHECK (platform IN ('bilibili', 'douyin', 'xiaohongshu')),
+    logged_in BOOLEAN DEFAULT FALSE,
+    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
+    UNIQUE(user_id, platform)
+);
+
+-- 4. 创建索引
+CREATE INDEX IF NOT EXISTS idx_users_email ON users(email);
+CREATE INDEX IF NOT EXISTS idx_sessions_user_id ON user_sessions(user_id);
+CREATE INDEX IF NOT EXISTS idx_social_user_platform ON social_accounts(user_id, platform);
+```
+
+---
+
+## 步骤 2: 配置后端环境变量
+
+编辑 `/home/rongye/ProgramFiles/ViGent2/backend/.env`：
+
+```env
+# =============== Supabase 配置 ===============
+SUPABASE_URL=https://your-project.supabase.co
+SUPABASE_KEY=eyJhbGciOiJIUzI1NiIs...
+
+# =============== JWT 配置 ===============
+JWT_SECRET_KEY=随机生成的32位以上字符串
+JWT_ALGORITHM=HS256
+JWT_EXPIRE_HOURS=168  # 7天
+
+# =============== 管理员配置 ===============
+ADMIN_EMAIL=admin@example.com
+ADMIN_PASSWORD=YourSecurePassword123!
+```
+
+### 生成 JWT 密钥
+
+```bash
+python3 -c "import secrets; print(secrets.token_urlsafe(32))"
+```
+
+---
+
+## 步骤 3: 安装依赖
+
+```bash
+cd /home/rongye/ProgramFiles/ViGent2/backend
+source venv/bin/activate
+
+pip install supabase python-jose[cryptography] passlib[bcrypt]
+```
+
+---
+
+## 步骤 4: 启动服务
+
+```bash
+# 重启后端服务
+pm2 restart vigent2-backend
+```
+
+首次启动时，管理员账号会自动创建。查看日志确认：
+
+```bash
+pm2 logs vigent2-backend | grep "管理员"
+```
+
+应该看到：`管理员账号已创建: admin@example.com`
+
+---
+
+## 步骤 5: 验证
+
+### API 测试
+
+```bash
+# 健康检查
+curl http://localhost:8006/health
+
+# 注册测试
+curl -X POST http://localhost:8006/api/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{"email":"test@example.com","password":"123456"}'
+
+# 登录测试 (管理员)
+curl -X POST http://localhost:8006/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@example.com","password":"YourSecurePassword123!"}'
+```
+
+---
+
+## 步骤 6: 防止 Supabase 7 天暂停
+
+Supabase 免费版 7 天无活动会暂停。推荐使用服务器 crontab 方案。
+
+### 方案 A: 服务器 crontab（推荐）
+
+在 Ubuntu 服务器上执行：
+
+```bash
+crontab -e
+```
+
+添加以下行（每天凌晨 1 点执行）：
+
+```cron
+0 1 * * * curl -s -X GET "https://zcmitzlqlyzxlgwagouf.supabase.co/rest/v1/" -H "apikey: YOUR_SUPABASE_ANON_KEY" > /dev/null
+```
+
+> 将 `YOUR_SUPABASE_ANON_KEY` 替换为实际的 anon key
+
+### 方案 B: GitHub Actions
+
+如果服务器可能长期关闭，可使用 GitHub Actions。
+
+1. 创建独立仓库：`supabase-keep-alive`
+2. 上传 `.github/workflows/keep-supabase-alive.yml`
+3. 配置 Secrets：`SUPABASE_URL`, `SUPABASE_KEY`
+
+> ⚠️ 需要 GitHub 账户有付款信息（免费计划也需要）

+
+---
+
+## 🔑 用户管理
+
+### 在 Supabase Dashboard 中管理
+
+1. 进入 **Table Editor > users**
+2. 激活用户：设置 `is_active = true`, `role = user`
+3. 设置过期时间：填写 `expires_at` 字段
+
+### 使用 API 管理
+
+需要管理员 Cookie：
+
+```bash
+# 获取用户列表
+curl http://localhost:8006/api/admin/users -b "access_token=..."
+
+# 激活用户 (30天有效期)
+curl -X POST http://localhost:8006/api/admin/users/{user_id}/activate \
+  -H "Content-Type: application/json" \
+  -b "access_token=..." \
+  -d '{"expires_days": 30}'
+```

-### 创建 pm2 配置文件
+### 1. 启动后端服务 (FastAPI)

-创建 `/home/rongye/ProgramFiles/ViGent2/ecosystem.config.js`:
+建议使用 Shell 脚本启动以避免环境问题。

-```javascript
-module.exports = {
-  apps: [
-    {
-      name: 'vigent2-backend',
-      cwd: '/home/rongye/ProgramFiles/ViGent2/backend',
-      script: 'venv/bin/uvicorn',
-      args: 'app.main:app --host 0.0.0.0 --port 8006',
-      interpreter: 'none',
-      env: {
-        PATH: '/home/rongye/ProgramFiles/ViGent2/backend/venv/bin:' + process.env.PATH
-      }
-    },
-    {
-      name: 'vigent2-frontend',
-      cwd: '/home/rongye/ProgramFiles/ViGent2/frontend',
-      script: 'npm',
-      args: 'run start',
-      env: {
-        PORT: 3002
-      }
-    },
-    {

-      args: '-m scripts.server',
-      interpreter: '/home/rongye/miniconda3/envs/latentsync/bin/python'
-    }
-  ]
-};
+1. 创建启动脚本 `run_backend.sh`:
+```bash
+cat > run_backend.sh << 'EOF'
+#!/bin/bash
+cd /home/rongye/ProgramFiles/ViGent2/backend
+./venv/bin/uvicorn app.main:app --host 0.0.0.0 --port 8006
+EOF
+chmod +x run_backend.sh
 ```

-### 启动服务
+2. 使用 pm2 启动:
+```bash
+pm2 start ./run_backend.sh --name vigent2-backend
+```
+
+### 2. 启动前端服务 (Next.js)
+
+⚠️ **注意**：生产模式启动前必须先进行构建。

 ```bash
-cd /home/rongye/ProgramFiles/ViGent2
+cd /home/rongye/ProgramFiles/ViGent2/frontend

-# 启动所有服务
-pm2 start ecosystem.config.js
+# 1. 构建项目 (如果之前没跑过或代码有更新)
+npm run build

-# 查看状态
-pm2 status
+# 2. 启动服务
+pm2 start npm --name vigent2-frontend -- run start -- -p 3002
+```

-# 设置开机自启
+### 3. 启动 LatentSync 模型服务
+
+1. 创建启动脚本 `run_latentsync.sh` (使用你的 conda python 路径):
+```bash
+cat > run_latentsync.sh << 'EOF'
+#!/bin/bash
+cd /home/rongye/ProgramFiles/ViGent2/models/LatentSync
+# 替换为你的实际 Python 路径
+/home/rongye/ProgramFiles/miniconda3/envs/latentsync/bin/python -m scripts.server
+EOF
+chmod +x run_latentsync.sh
+```
+
+2. 使用 pm2 启动:
+```bash
+pm2 start ./run_latentsync.sh --name vigent2-latentsync
+```
+
+### 4. 保存当前列表 (开机自启)
+
+```bash
 pm2 save
-pm2 startup  # 按提示执行生成的命令
+pm2 startup
 ```

+### SSH 连接卡顿 / 系统响应慢
+
+**原因**：LatentSync 模型服务启动时会占用大量 I/O 和 CPU 资源，或者模型加载到 GPU 时导致瞬时负载过高。
+
+**解决**：
+1. 检查系统负载：`top` 或 `htop`
+2. 如果不需要实时生成视频，可以暂时停止 LatentSync 服务：
+   ```bash
+   pm2 stop vigent2-latentsync
+   ```
+3. 确保服务器有足够的 RAM 和 Swap 空间。
+4. **代码级优化**：已在 `scripts/server.py` 和 `scripts/inference.py` 中强制限制 `OMP_NUM_THREADS=8`，防止 PyTorch 占用所有 CPU 核心导致系统假死。

+
+## 🔐 用户认证系统实现 (2026-01-23)
+
+### 问题描述
+为了支持多用户管理和资源隔离，需要实现一套完整的用户认证系统，取代以前的单用户模式。要求：
+- 使用 Supabase 作为数据库
+- 支持注册、登录、登出
+- 管理员审核机制 (is_active)
+- 单设备登录限制
+- HttpOnly Cookie 存储 Token
+
+### 解决方案
+
+#### 1. 数据库设计 (Supabase)
+创建了三张核心表：
+- `users`: 存储邮箱、密码哈希、角色、激活状态
+- `user_sessions`: 存储 Session Token，实现单设备登录 (后踢前)
+- `social_accounts`: 社交账号绑定信息 (B站/抖音Cookie)
+
+#### 2. 后端实现 (FastAPI)
+- **依赖注入** (`deps.py`): `get_current_user` 自动验证 Token 和 Session
+- **安全模块** (`security.py`): JWT 生成与验证，密码 bcrypt 哈希
+- **路由模块** (`auth.py`): 
+  - `/register`: 注册后默认为 `pending` 状态
+  - `/login`: 验证通过后生成 JWT 并写入 HttpOnly Cookie
+  - `/me`: 获取当前用户信息
+
+#### 3. 部署方案
+- 采用 Supabase 云端免费版
+- 为了防止 7 天不活跃暂停，配置了 GitHub Actions / Crontab 自动保活
+- 创建了独立的部署文档 `Docs/AUTH_DEPLOY.md`
+
+### 结果
+- ✅ 成功实现了完整的 JWT 认证流程
+- ✅ 管理员可以控制用户激活状态
+- ✅ 实现了安全的无感 Token 刷新 (Session Token)
+- ✅ 敏感配置 (Supabase Key) 通过环境变量管理

+
+## 🛠️ 部署调试记录 (2026-01-23)
+
+### 1. 服务启动方式修正
+- **问题**: pm2 直接启动 python/uvicorn 会导致 `SyntaxError` (Node.js 尝试解释 Python)
+- **解决**: 改用 `.sh` 脚本封装启动命令
+
+### 2. 依赖缺失与兼容性
+- **问题 1**: `ImportError: email-validator is not installed` (Pydantic 依赖)
+  - **修复**: 添加 `email-validator>=2.1.0`
+- **问题 2**: `AttributeError: module 'bcrypt' has no attribute '__about__'` (Passlib 兼容性)
+  - **修复**: 锁定 `bcrypt==4.0.1`
+
+### 3. 前端生产环境构建
+- **问题**: `Error: Could not find a production build`
+- **解决**: 启动前必须执行 `npm run build`
+
+### 4. 性能调优
+- **现象**: SSH 远程连接出现显著卡顿
+- **排查**: `vigent2-latentsync` 启动时模型加载占用大量系统资源
+- **优化**: 生产环境建议按需开启 LatentSync 服务，或确保服务器 IO/带宽充足。停止该服务后 SSH 恢复流畅。

 ### 新建判断 (对话开始前)
 1. **回顾进度**：查看 `task_complete.md` 了解当前状态
 2. **检查日期**：查看最新 `DayN.md`
-   - **今天** → 追加到现有文件
-   - **之前** → 创建 `Day{N+1}.md`
+   - **今天 (与当前日期相同)** → 🚨 **绝对禁止创建新文件**，必须**追加**到现有 `DayN.md` 末尾！即使是完全不同的功能模块。
+   - **之前 (昨天或更早)** → 创建 `Day{N+1}.md`
