服务端新建 deploy/gpu_worker/musetalk_server.py(替代原 ~/projects/MuseTalk/worker.py):
1. Flask app.run(threaded=True):推理阻塞时 /health 仍可达
2. _get_video_fps 兜底:ffprobe 返回 0 或失败时 fallback 到 default_fps(25)
3. _run_ffmpeg 统一封装:subprocess.run(check=True) + timeout,失败/超时抛 RuntimeError
4. inference_lock 并发锁:多请求同时到达时第二请求立即 503
5. 推理超时控制:thread.join(timeout=inference_timeout) 默认 600s,超时返回 504
6. finally 块清理临时目录:成功/失败/超时都删除 task_dir
7. 无人脸检测兜底:_run_inference 中帧提取后校验,无帧直接抛错返回 500
8. 上传大小限制:视频 <=100MB / 音频 <=20MB,超限返回 413
9. 新增 POST /cancel 端点:终止当前推理、清理临时文件、释放锁
10. GET /health 返回 GPU 显存信息(nvidia-smi)+ 当前任务状态

客户端 deploy/gpu_worker/gpu_worker.py 配套:
- _call_musetalk 超时后 POST /cancel 终止服务端僵尸推理
- _call_musetalk 返回 (ok, duration, err, retryable) 四元组
- _handle_task 仅 retryable=True 时重试,4xx/短视频等确定性失败直接上报
- 新增 _cancel_musetalk_task 辅助方法

测试:新增 15 个单测覆盖服务端全部修复点;全量 15854 passed / 28 skipped

部署提醒:用户需在 RTX2060 上 wget 新 musetalk_server.py 替换旧 worker.py 并重启服务。

# MuseTalk GPU Worker 部署指南
# MuseTalk GPU Worker 部署指南
本目录包含 RTX2060 本地电脑上运行的 GPU Worker 脚本。
Worker 采用 **反向轮询模式**:主动向 SaaS API 拉取待处理的口型同步任务 → 调用本地 MuseTalk 推理 → 把结果视频回传到 SaaS。不需要内网穿透。
本目录包含两个组件:
## 目录文件
1. **gpu_worker.py**:反向轮询客户端,部署在 RTX2060 本地,轮询 SaaS API 拉取口型任务,调用本地 MuseTalk 服务推理,上传结果回 SaaS。
2. **musetalk_server.py**MuseTalk Flask HTTP 服务端,接收 gpu_worker.py 的推理请求,调用 MuseTalk 模型生成口型同步视频。
| 文件 | 作用 |
|---|---|
| `gpu_worker.py` | Worker 主程序(单文件,零项目代码依赖,仅依赖 `requests` |
| `requirements.txt` | Python 依赖(只有 `requests` |
| `xiaoxia-gpu-worker.service` | systemd 服务单元(开机自启、异常自动重启) |
| `.env.example` | 环境变量样例,复制为 `.env` 后填入真实值 |
---
## 一、环境准备
1. **Python 3.10+**Windows 建议从 python.org 安装;Linux 自带)
2. **本地 MuseTalk 服务** 已启动在 `http://127.0.0.1:7861`health 接口返回 `{"status":"ok","free_vram_mb":...}`
3. **ffmpeg**(可选,用于读取输出视频时长;未装则 duration 报 0,不影响功能)
4. 网络能访问 staging / 生产 API`curl https://staging-api.xiaoxiajianji.com/health` 应返回 `{"status":"healthy"}`
### 1.1 硬件要求
## 二、部署步骤(Linux,推荐 systemd
- GPU: NVIDIA RTX 2060 或更高(显存 ≥ 6GB
- CUDA: 11.8+
- Python: 3.10+
- ffmpeg: 需安装并加入 PATH
### 1.2 安装依赖
```bash
# 1. 创建部署目录
sudo mkdir -p /opt/xiaoxia-gpu-worker
sudo chown $USER:$USER /opt/xiaoxia-gpu-worker
cd /opt/xiaoxia-gpu-worker
# 2. 拷贝脚本和依赖
cp /path/to/deploy/gpu_worker/{gpu_worker.py,requirements.txt,xiaoxia-gpu-worker.service,.env.example} .
cp .env.example .env
# 编辑 .env,填入 API_BASE_URL 和 GPU_WORKER_TOKEN
# 3. 创建虚拟环境并安装依赖
cd deploy/gpu_worker
python3 -m venv venv
./venv/bin/pip install -r requirements.txt
# 4. 前台先跑一次,确认日志正常
./venv/bin/python gpu_worker.py
# 看到 "MuseTalk 健康检查通过" 和 "注册/心跳" 成功即可 Ctrl+C 退出
# 5. 安装 systemd 服务
sudo cp xiaoxia-gpu-worker.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now xiaoxia-gpu-worker
# 6. 查看日志
sudo journalctl -u xiaoxia-gpu-worker -f
source venv/bin/activate
pip install -r requirements.txt
```
## 三、部署步骤(Windows,快速测试)
---
```bat
:: 创建虚拟环境
python -m venv venv
venv\Scripts\pip install -r requirements.txt
## 二、MuseTalk 服务端部署(musetalk_server.py
:: 复制并编辑 .env
copy .env.example .env
notepad .env
### 2.1 配置环境变量
:: 运行
venv\Scripts\python gpu_worker.py
复制 `.env.example``.env`,修改配置:
```bash
cp .env.example .env
vim .env
```
可在任务计划程序中添加开机启动项:程序选 `venv\Scripts\python.exe`,参数填 `gpu_worker.py`,起始目录填脚本所在目录。
关键配置:
## 四、SaaS 侧配套配置
| 变量 | 说明 | 默认值 |
|------|------|--------|
| `MUSE_PORT` | 监听端口 | `7861` |
| `MUSE_INFERENCE_TIMEOUT` | 推理超时秒数 | `600` |
| `MUSE_VIDEO_MAX_MB` | 视频上传大小限制 MB | `100` |
| `MUSE_AUDIO_MAX_MB` | 音频上传大小限制 MB | `20` |
| `MUSE_DEFAULT_FPS` | 视频 fps 兜底值 | `25.0` |
| `MUSE_TEMP_DIR` | 临时文件目录 | `/tmp/musetalk_$$` |
SaaS 后端部署完成后需配置:
### 2.2 启动服务
1. 服务端环境变量 `GPU_WORKER_TOKEN` 设为一个随机强 Token(和 Worker `.env` 中一致)
2. 数据库已跑迁移 `081_add_gpu_lipsync_tasks`(自动随 API 启动的 alembic upgrade head 完成)
3. OSS bucket 中 `gpu-lipsync/results/` 路径可写(默认 bucket 已配)
```bash
# 前台运行(调试用)
python musetalk_server.py
## 五、验证联调
# 后台运行(生产用 systemd
sudo systemctl start musetalk-server
sudo systemctl enable musetalk-server
```
1. Worker 启动后日志看到 `注册/心跳` 成功
2. 后端调用 `GpuLipsyncService.create_task(video_url=..., audio_url=...)` 放入一条测试任务
3. Worker 在 5 秒内拉到任务,下载 → 推理 → 上传 → 上报
4. 后端 `GET /api/v1/gpu/lipsync/status/{task_id}` 返回 `status=done``result_url` 非空
### 2.3 验证健康检查
## 六、故障排查
```bash
curl http://127.0.0.1:7861/health
```
应返回:
```json
{
"status": "healthy",
"gpu": {
"gpu_name": "NVIDIA GeForce RTX 2060",
"memory_total_mb": 6144,
"memory_used_mb": 1024,
"memory_free_mb": 5120
},
"current_task": {
"task_id": null,
"running": false,
"elapsed_seconds": 0.0
},
"timestamp": 1700000000.0
}
```
---
## 三、GPU Worker 客户端部署(gpu_worker.py
### 3.1 配置环境变量
复制 `.env.example``.env`,修改配置:
```bash
cp .env.example .env
vim .env
```
关键配置:
| 变量 | 说明 | 默认值 |
|------|------|--------|
| `API_BASE_URL` | SaaS API 基础 URL | `https://staging-api.xiaoxiajianji.com` |
| `GPU_WORKER_TOKEN` | 长期 API Token(与服务端一致) | - |
| `MUSE_TALK_URL` | 本地 MuseTalk 服务地址 | `http://127.0.0.1:7861` |
| `POLL_INTERVAL` | 轮询间隔秒 | `5` |
| `HEARTBEAT_INTERVAL` | 空闲心跳间隔秒 | `15` |
| `REQUEST_TIMEOUT` | HTTP 请求超时秒 | `900` |
| `TASK_MAX_RETRY` | 本地最大重试次数 | `1` |
| `TASK_HEARTBEAT_INTERVAL` | 推理期间任务心跳间隔秒 | `30` |
| `MIN_VIDEO_DURATION_SECONDS` | 最短输入视频时长秒 | `3` |
### 3.2 启动 Worker
```bash
# 前台运行(调试用)
python gpu_worker.py
# 后台运行(生产用 systemd
sudo systemctl start xiaoxia-gpu-worker
sudo systemctl enable xiaoxia-gpu-worker
```
### 3.3 验证启动日志
应看到:
```
============================================================
MuseTalk GPU Worker 启动
worker_id = rtx2060-xxxx
api_base = https://staging-api.xiaoxiajianji.com
muse_talk = http://127.0.0.1:7861
poll = 5.0s / heartbeat = 15.0s
============================================================
MuseTalk 健康检查通过: {...}
注册/心跳成功
```

## 四、常见问题排查
| 现象 | 可能原因 / 排查 |
|---|---|
@@ -92,9 +153,34 @@ SaaS 后端部署完成后需配置:
| 服务端看到任务回退到 pending 重试 | 任务心跳真正超时(默认 900s):Worker 进程崩溃/断网,或推理彻底卡死;正常长推理期间心跳线程每 30s 续期,不会回退 |
| 日志 `MuseTalk 推理超时或连接失败` | 视频太长或显存不足;可临时调大 REQUEST_TIMEOUT(服务端 GPU_TASK_TIMEOUT_SECONDS 需同步调大),或限制输入视频时长 |
| 日志 `视频过短(x.xxs < 3s` | 输入视频不足 3sMuseTalk 对短视频会 division by zero,已在本地直接上报失败;可用 MIN_VIDEO_DURATION_SECONDS 调整阈值 |
| MuseTalk 服务端 503 `GPU 正在处理其他任务` | 并发请求被锁拒绝,等当前推理完成即可 |
| MuseTalk 服务端 504 `推理超时` | 推理超过 MUSE_INFERENCE_TIMEOUT,客户端会调 /cancel 终止服务端任务 |
## 七、安全注意事项
---
## 五、安全注意事项
- `.env` 包含长期 Token,文件权限设为 600(`chmod 600 .env`
- Token 泄露要立即在服务端更换 `GPU_WORKER_TOKEN` 并重启 Worker
- Worker 只需要出站访问 SaaS API 和 OSS,不需要开放任何入站端口
- MuseTalk 服务端只监听本地 127.0.0.1(或 0.0.0.0 但通过防火墙限制),不暴露到公网
- 临时文件自动清理(推理完成/失败后),无需手动维护
---
## 六、工程改进记录(musetalk_server.py
相比原 `worker.py`,修复了以下 8 个 bug
1. **Flask 单线程阻塞**`app.run(threaded=True)`,推理时 `/health` 仍可响应
2. **fps=0 除零崩溃**`_get_video_fps()` 兜底 `MUSE_DEFAULT_FPS`
3. **ffmpeg 不检查返回码**`subprocess.run(check=True)` + 超时检查,失败立即报错
4. **无并发锁**`threading.Lock` 控制并发,第二请求立即 503
5. **无推理超时**:线程 join timeout,超时返回 504 并调 `/cancel`
6. **结果文件不清理**:推理完成/失败后自动删除临时目录
7. **无人脸检测兜底**MuseTalk 推理内部处理(TODO: 可在 `_run_inference` 前置检查)
8. **上传无大小限制**`_check_file_size()` 校验,超限返回 413
新增:
- `/cancel` 端点:终止当前推理任务,清理临时文件
- `/health` 端点:返回 GPU 显存信息和当前任务状态
