+```
+
+## 一次性准备（在业务服务器上执行）
+
+### 1. 安装 Gitea Actions Runner
+
+```bash
+# 下载 act_runner
+cd /opt
+wget https://gitea.com/gitea/act_runner/releases/download/v0.2.11/act_runner-0.2.11-linux-amd64 -O act_runner
+chmod +x act_runner
+mv act_runner /usr/local/bin/
+
+# 注册 runner（到 git.qiukai.me）
+# 先在 Gitea 网页：仓库设置 → Actions → Runners → New runner，获取 token
+act_runner register \
+  --instance https://git.qiukai.me \
+  --token <YOUR_RUNNER_TOKEN> \
+  --name prod-deploy \
+  --labels prod-deploy \
+  --no-interactive
+
+# 安装为系统服务
+act_runner daemon --config /etc/act_runner/config.yaml &
+# 或用 systemd：
+cat > /etc/systemd/system/act-runner.service <<'EOF'
+[Unit]
+Description=Gitea Actions Runner
+After=network.target
+
+[Service]
+Type=simple
+ExecStart=/usr/local/bin/act_runner daemon
+Restart=on-failure
+Environment=HOME=/root
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+systemctl daemon-reload
+systemctl enable --now act-runner
+```
+
+### 2. 创建部署目录结构
+
+```bash
+mkdir -p /opt/opc-manager/{releases,shared/uploads}
+```
+
+### 3. 创建 .env 文件
+
+```bash
+cat > /opt/opc-manager/shared/.env <<'EOF'
+SECRET_KEY=改成一串随机字符串_至少32位
+DB_HOST=127.0.0.1
+DB_PORT=3306
+DB_USER=opc
+DB_PASSWORD=opc123456
+DB_NAME=opc
+FLASK_DEBUG=false
+EOF
+
+chmod 600 /opt/opc-manager/shared/.env
+```
+
+### 4. 安装 systemd service
+
+```bash
+# 从仓库的 deploy/opc-manager.service 复制
+cat > /etc/systemd/system/opc-manager.service <<'EOF'
+[Unit]
+Description=OPC Manager (Flask)
+After=network.target mysql.service
+
+[Service]
+Type=simple
+WorkingDirectory=/opt/opc-manager/current
+ExecStart=/opt/opc-manager/current/.venv/bin/gunicorn --preload -w 4 -b 0.0.0.0:5177 backend.flask_app:app
+Restart=on-failure
+RestartSec=5
+EnvironmentFile=/opt/opc-manager/current/.env
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+systemctl daemon-reload
+systemctl enable opc-manager
+```
+
+### 5. 配置 Gitea Secret
+
+在 Gitea 网页操作：
+1. 进入仓库 `qiukai/opc-manager`
+2. 设置 → Actions → Secrets → New Secret
+3. Name: `DEPLOY_TOKEN`
+4. Value: 你的 Gitea Personal Access Token（需要有 repo 读权限）
+   - 生成路径：头像 → 设置 → 应用 → 生成令牌
+
+### 6. 首次手动部署
+
+push 代码前，先手动跑一次确保目录结构正确：
+
+```bash
+cd /opt/opc-manager
+git clone --depth 1 --branch main https://git.qiukai.me/qiukai/opc-manager.git /tmp/opc-init
+RELEASE_DIR=/opt/opc-manager/releases/initial
+mkdir -p "${RELEASE_DIR}"
+rsync -a --exclude='.git' --exclude='.env' --exclude='.venv' /tmp/opc-init/ "${RELEASE_DIR}/"
+ln -sfn /opt/opc-manager/shared/.env "${RELEASE_DIR}/.env"
+ln -sfn /opt/opc-manager/shared/uploads "${RELEASE_DIR}/data/uploads"
+cd "${RELEASE_DIR}"
+python3 -m venv .venv
+. .venv/bin/activate
+pip install -r requirements.txt
+ln -sfn "${RELEASE_DIR}" /opt/opc-manager/current
+systemctl start opc-manager
+curl http://127.0.0.1:5177/api/health
+rm -rf /tmp/opc-init
+```
+
+## 日常使用
+
+### 发布新版本
+```bash
+# 本地
+git push origin main
+# 自动触发 Gitea Actions → 服务器自动部署
+```
+
+### 查看部署状态
+```bash
+# 在 Gitea 网页：仓库 → Actions 查看部署日志
+# 或在服务器：
+systemctl status opc-manager
+ls -la /opt/opc-manager/current
+```
+
+### 回滚
+```bash
+# 列出历史版本
+ls -t /opt/opc-manager/releases
+# 切换到上一个版本
+PREV=$(ls -t /opt/opc-manager/releases | sed -n '2p')
+ln -sfn "/opt/opc-manager/releases/${PREV}" /opt/opc-manager/current
+systemctl restart opc-manager
+```
+
+## Nginx 反代（可选）
+
+```nginx
+server {
+    listen 80;
+    server_name opc.yxcowork.vip;
+    location / {
+        proxy_pass http://127.0.0.1:5177;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    }
+}
+```

+# OPC-Manager 自动化部署配置任务
+
+## 背景
+OPC-Manager 项目（Flask + MySQL，端口 5177）需要配置 Gitea Actions 自动化部署。参考 SalesManager 的模式：push 到 main 分支后自动部署到业务服务器。部署工作流文件已写好（`.gitea/workflows/deploy.yml`），需要在服务器上完成一次性准备。
+
+## 服务器信息
+- 业务服务器：82.157.208.197（SSH 别名 `ssh business`）
+- Gitea 地址：https://git.qiukai.me
+- 仓库：qiukai/opc-manager
+- 服务端口：5177
+- MySQL：已安装（8.0.45，系统服务），数据库 `opc`，用户 `opc/opc123456`
+
+## 需要完成的 5 个步骤
+
+### 1. 安装 Gitea Actions Runner
+在业务服务器上安装 `act_runner` 并注册到 Gitea：
+- 下载地址：https://gitea.com/gitea/act_runner/releases/download/v0.2.11/act_runner-0.2.11-linux-amd64
+- 放到 `/usr/local/bin/act_runner`
+- 注册时 name=`prod-deploy`，labels=`prod-deploy`
+- 注册 token 需要到 Gitea 网页获取：仓库 qiukai/opc-manager → 设置 → Actions → Runners → New runner
+- 安装为 systemd 服务（`/etc/systemd/system/act-runner.service`），开机自启
+
+### 2. 创建部署目录结构
+```bash
+mkdir -p /opt/opc-manager/{releases,shared/uploads}
+```
+
+### 3. 创建 .env 文件
+在 `/opt/opc-manager/shared/.env` 创建环境变量文件：
+```
+SECRET_KEY=随机生成32位以上字符串
+DB_HOST=127.0.0.1
+DB_PORT=3306
+DB_USER=opc
+DB_PASSWORD=opc123456
+DB_NAME=opc
+FLASK_DEBUG=false
+```
+权限设为 600。
+
+### 4. 安装 systemd service
+创建 `/etc/systemd/system/opc-manager.service`：
+```ini
+[Unit]
+Description=OPC Manager (Flask)
+After=network.target mysql.service
+
+[Service]
+Type=simple
+WorkingDirectory=/opt/opc-manager/current
+ExecStart=/opt/opc-manager/current/.venv/bin/gunicorn --preload -w 4 -b 0.0.0.0:5177 backend.flask_app:app
+Restart=on-failure
+RestartSec=5
+EnvironmentFile=/opt/opc-manager/current/.env
+
+[Install]
+WantedBy=multi-user.target
+```
+执行 `systemctl daemon-reload && systemctl enable opc-manager`（先不 start，等首次部署后自动启动）。
+
+### 5. 配置 Gitea Secret
+在 Gitea 网页操作（需要用户在浏览器完成）：
+- 进入仓库 qiukai/opc-manager → 设置 → Actions → Secrets → New Secret
+- Name: `DEPLOY_TOKEN`
+- Value: 用户的 Gitea Personal Access Token（需 repo 读权限）
+  - 生成路径：头像 → 设置 → 应用 → 生成令牌
+
+## 首次部署验证
+准备完成后，在本地执行一次 `git push origin main`，观察：
+1. Gitea 网页 Actions 页面是否有部署任务在运行
+2. 部署日志是否正常
+3. 部署完成后 `curl http://127.0.0.1:5177/api/health` 是否返回 `{"ok":true,"service":"opc-manager"}`
+4. `systemctl status opc-manager` 是否 active
+
+## 参考文件
+项目的部署工作流在仓库的 `.gitea/workflows/deploy.yml`，systemd 模板在 `deploy/opc-manager.service`，完整说明在 `deploy/README.md`。
+
+## 注意事项
+- Gitea Runner 的 token 需要用户在浏览器获取后告诉你，你无法自动获取
+- Gitea Secret (DEPLOY_TOKEN) 也需要用户在浏览器配置
+- 如果服务器没有 python3.11+，需要先安装（OPC-Manager 要求 Python 3.9+）
+- 确保服务器已安装 git、rsync、curl（一般都有）
