+
+## 七、自动部署
+
+从 2026-09-20 起，GPU 节点配置文件和脚本全部入库到 `deploy/gpu_worker/`，支持一键初始化新节点 + develop 分支 push 后 30 秒内自动拉取更新。
+
+### 7.1 服务架构
+
+每个 GPU 渲染节点运行三个 systemd 单元：
+
+| 单元 | 类型 | 作用 |
+|---|---|---|
+| `musetalk-worker.service` | simple（常驻） | MuseTalk Flask 推理 API（监听 127.0.0.1:7861） |
+| `xiaoxia-gpu-worker.service` | simple（常驻） | 反向轮询 SaaS API 拉口型任务的 Worker 客户端 |
+| `gpu-poll.timer` + `gpu-poll.service` | timer（每 30s 触发 oneshot） | 轮询 Gitea `deploy/gpu_worker/` 最新 commit，有变更自动执行 update 脚本 |
+
+脚本目录（节点本地）：
+
+| 路径 | 来源 | 作用 |
+|---|---|---|
+| `~/projects/update-gpu-worker.sh` | `scripts/update-gpu-worker.sh` | 备份 → 拉代码 → 重启两个服务 → 健康检查 → 失败回滚 |
+| `~/projects/gpu-webhook/poll_and_update.sh` | `scripts/poll_and_update.sh` | 轮询 Gitea API 比对 SHA，有新 commit 时触发 update |
+
+### 7.2 新节点部署步骤
+
+**前置准备**（手动，首次部署必做）：
+
+1. 安装 NVIDIA 驱动 + CUDA 11.8+，`nvidia-smi` 能看到 GPU
+2. 克隆 MuseTalk 代码到 `~/projects/MuseTalk/`，下载模型权重到 `~/projects/MuseTalk/models/musetalk/`（权重约几 GB，不适合自动下载）
+3. 创建 Python 虚拟环境 `~/projects/MuseTalk/venv/` 并安装 MuseTalk 依赖（PyTorch CUDA 版等）
+4. 创建 Worker 虚拟环境 `/opt/xiaoxia-gpu-worker/venv/` 并 `pip install -r requirements.txt`
+5. 准备 `.env` 文件（Worker 端）：`/opt/xiaoxia-gpu-worker/.env`，填好 `API_BASE_URL`、`GPU_WORKER_TOKEN`、`MUSE_TALK_URL` 等（参考 `.env.example`）
+
+> ⚠️ 模型权重和 Python 虚拟环境（含 CUDA 版 PyTorch）体积大、安装慢，首次部署必须手动准备；后续脚本只更新 `.py` 文件和配置，不碰权重和 venv。
+
+**一键初始化**：
+
+```bash
+# 从仓库拉取 setup 脚本并执行（在全新 GPU 机器上以 ying 用户执行）
+wget -q -O /tmp/setup-gpu-node.sh \
+  "https://git.xiaoxiajianji.com/xiaoxia/xiaoxia-saas/raw/branch/develop/deploy/gpu_worker/scripts/setup-gpu-node.sh"
+bash /tmp/setup-gpu-node.sh
+```
+
+脚本自动完成：
+
+1. apt 安装系统依赖（python3、ffmpeg、wget、curl、git）
+2. 创建必要目录（`~/projects/MuseTalk`、`~/projects/gpu-webhook`、`/opt/xiaoxia-gpu-worker`）
+3. 从仓库拉取三个 systemd 单元文件 + update/poll 脚本到本地
+4. 安装 systemd 服务到 `/etc/systemd/system/`
+5. 配置 sudo 免密（仅允许 `ying` 用户免密 restart 两个服务、status、journalctl、cp、chmod、tee）
+6. 首次执行 update 脚本拉取最新 `musetalk_server.py` 和 `gpu_worker.py`
+7. `systemctl daemon-reload` + enable + start 三个单元
+
+**初始化后检查**：
+
+```bash
+sudo systemctl status musetalk-worker       # 应 active (running)
+sudo systemctl status xiaoxia-gpu-worker    # 应 active (running)
+sudo systemctl status gpu-poll.timer        # 应 active (waiting)
+curl http://127.0.0.1:7861/health          # 应返回 healthy + GPU 显存信息
+```
+
+### 7.3 自动更新机制
+
+push 到 `develop` 分支且修改了 `deploy/gpu_worker/` 下任何文件后：
+
+1. `gpu-poll.timer` 每 30 秒触发 `gpu-poll.service`
+2. `poll_and_update.sh` 调用 Gitea API 取 `deploy/gpu_worker/` 路径最新 commit SHA
+3. 与本地 `~/projects/gpu-webhook/.last_commit` 比对，无变更直接退出
+4. 有变更：写入新 SHA → 执行 `update-gpu-worker.sh`
+5. `update-gpu-worker.sh` 执行流程：
+   - 备份当前 `musetalk_server.py` / `gpu_worker.py`（带时间戳后缀）
+   - wget 拉取最新 `musetalk_server.py`、`gpu_worker.py`
+   - 比对 `requirements.txt`，有变化则 pip install
+   - `sudo systemctl restart musetalk-worker`，等 5 秒
+   - `sudo systemctl restart xiaoxia-gpu-worker`，等 8 秒
+   - `curl http://127.0.0.1:7861/health` 健康检查
+   - 健康 → 写日志退出 0
+   - 不健康 → 回滚到最新备份 → 重启 → 退出 1（日志记录 rolled back）
+
+端到端延迟：从 push 到节点拉到新代码并重启，约 30~60 秒。
+
+### 7.4 手动更新命令
+
+```bash
+# 立即手动触发一次更新（不依赖 timer）
+bash ~/projects/update-gpu-worker.sh
+
+# 查看更新日志
+tail -f /tmp/gpu-worker-update.log
+
+# 查看轮询日志
+tail -f /tmp/gpu-poll.log
+
+# 查看服务运行日志
+journalctl -u musetalk-worker -f          # MuseTalk 推理服务日志
+journalctl -u xiaoxia-gpu-worker -f       # GPU Worker 客户端日志
+journalctl -u gpu-poll.service -f         # 轮询/更新触发日志
+```

+### 7.6 注意事项
+
+- **首次部署必须手动准备**：MuseTalk 代码仓库、模型权重（`models/musetalk/`，几 GB）、MuseTalk 的 Python 虚拟环境（`venv/`，含 CUDA 版 PyTorch）。这些体积大、安装耗时长，不在自动更新范围内。
+- **脚本路径写死**：当前脚本路径固定为 `/home/ying/projects/` 和 `/opt/xiaoxia-gpu-worker/`，用户名固定 `ying`。后续如有多节点/多用户需求再做参数化。
+- **sudo 免密范围最小化**：setup 脚本写入 `/etc/sudoers.d/ying-gpu-update`，仅放行 restart/status 两个 GPU 相关服务、daemon-reload、journalctl、cp、chmod、tee，不开放全量 root。
+- **回滚只回滚 .py 文件**：健康检查失败只回滚 `musetalk_server.py` 和 `gpu_worker.py`，不回滚 pip 依赖（requirements.txt 变化概率低，且 pip 操作本身可能失败）。如需完全回滚，手动 `pip install -r requirements.txt` 指定旧版本。
+- **poll 脚本容错**：Gitea API 请求失败直接跳过，不触发更新，不会因为网络抖动误重启服务。
