+# 生产部署（Docker）
+
+生产实例使用三个隔离容器：MySQL 系统数据库、Node.js 后端和部署注册服务。MySQL、后端与注册服务只映射到服务器回环地址，公网仅由 Nginx 暴露 `ck.yydd.ai:8443`。
+
+服务器目录约定：
+
+- `/opt/cangku/app`：仓库代码和前端构建结果
+- `/opt/cangku/shared`：权限为 `0700` 的环境配置
+- `/opt/cangku/data`：MySQL 和部署注册服务持久数据
+- `/www/wwwroot/cangku-acme`：Let's Encrypt HTTP-01 校验目录
+
+真实密码、JWT 密钥、部署 Key 和第三方数据库配置不得写入仓库。`mysql.env`、`backend.env` 和 `bootstrap.env` 只在服务器生成并保持 `0600` 权限。
+
+SSH 隧道账号只接受由注册服务 CA 签发的短期证书，只允许转发到服务器 `127.0.0.1:3307`，并关闭终端、TTY、代理转发和密码认证。生产主机的 SSH 管理账号使用独立密钥，关闭密码登录。
