+# deploy 部署目录说明
+
+本目录包含 chongming 应用在宿主机上的部署与运维相关文件。
+
+## 目录内容
+
+| 文件 | 作用 |
+|------|------|
+| [install_docker.sh](install_docker.sh) | 一键安装 Docker 引擎并配置国内公网镜像加速（Ubuntu 24.04 / amd64） |
+| [docker-compose.yml](docker-compose.yml) | Redis / PostgreSQL / MinIO / Mosquitto(MQTT) / Zenoh Router / Caddy 六类服务的编排定义 |
+| [.env](.env) | Compose 使用的连接凭据与环境变量（PostgreSQL 密码、MinIO 账号等，勿提交到仓库） |
+| [chongming.service](chongming.service) | chongming 应用的 systemd 服务单元文件 |
+| [caddy/Caddyfile](caddy/Caddyfile) | Caddy 反向代理配置（本地 IP + 自签证书，统一 HTTP/HTTPS 入口） |
+| [data/](data) | Compose 声明挂载的数据持久化目录（redis / postgres / minio / mosquitto / caddy 子目录），由容器产生，勿手动编辑 |
+
+---
+
+## 1. 安装 Docker
+
+首次在新机器上部署时，先安装 Docker：
+
+```bash
+sudo ./install_docker.sh
+```
+
+脚本会安装 `docker-ce` 及 Compose 插件，并将国内公网加速源写入 `/etc/docker/daemon.json`（多源容灾）。安装完成后即可使用 `docker compose`。
+
+> 说明：脚本使用的 `mirrors.cloud.tencent.com` 为腾讯云公网镜像站；原内网域名
+> `mirrors.tencentyun.com` / `mirror.ccs.tencentyun.com` 仅腾讯云 VPC 内访问，本机不可用。
+
+---
+
+## 2. 部署基础服务（Redis / PostgreSQL / MinIO / Mosquitto / Zenoh）
+
+五个服务分别用于 chongming 的缓存、元数据、对象存储、MQTT 消息与 Zenoh 路由汇聚。
+
+### 部署
+
+> 说明：Mosquitto 与 Zenoh Router 为按需启用项。若只想启动基础三服务（redis/postgres/minio），可加 `--no-recreate` 仅针对目标服务：
+
+```bash
+cd deploy
+# 启动全部服务（首次会自动拉取镜像并创建容器）
+sudo docker compose up -d
+
+# 仅启动消息/路由服务（保留已在运行的 redis/pg/minio）
+sudo docker compose up -d mosquitto zenoh
+
+# 仅启动基础数据服务
+sudo docker compose up -d redis postgres minio
+```
+
+### 服务清单（默认端口）
+
+| 服务 | 容器名 | 端口 | 说明 |
+|------|--------|------|------|
+| Redis 7 | chongming-redis | 6379 | 支持 appendonly 持久化 |
+| PostgreSQL 16 | chongming-postgres | 5432 | 元数据存储 |
+| MinIO | chongming-minio | 9000(S3) / 9001(Console) | 对象存储，Web 控制台 |
+| Mosquitto 2 | chongming-mosquitto | 1883 | MQTT Broker（WebSocket 9001 默认关闭，避免与 MinIO Console 冲突） |
+| Zenoh Router | chongming-zenoh | 7447/tcp、7447/udp | Zenoh 路由节点 |
+| Caddy | chongming-caddy | 80 / 443 | 统一反向代理入口（chongming Web / MinIO Console / MinIO API） |
+
+### 连接凭据（见 [.env](.env)）
+
+- PostgreSQL：用户 `postgres` / 密码 `postgres` / 库 `chongming`
+- MinIO：`minioadmin` / `minioadmin`
+- Mosquitto：匿名连接（如需账号，在 [mosquitto.conf](data/mosquitto/config/mosquitto.conf) 配置）
+
+### 数据持久化
+
+数据保存在 `deploy/data/{redis,postgres,minio,mosquitto}`，通过绑定挂载持久化，容器删除后数据不丢失。所有服务均设置 `restart: unless-stopped`（开机自启）。
+
+### 日常管理
+
+```bash
+sudo docker compose ps                       # 查看状态与健康度
+sudo docker compose logs -f <服务名>          # 查看日志
+sudo docker compose restart <服务名>          # 重启单个服务
+sudo docker compose down                     # 停止并移除容器（保留数据卷）
+sudo docker compose down -v                  # 停止并移除容器 + 数据卷（慎用，会清空数据）
+```
+
+### 验证
+
+```bash
+sudo docker exec chongming-redis redis-cli ping                        # 期望 PONG
+sudo docker exec chongming-postgres pg_isready -U postgres -d chongming # 期望 accepting connections
+sudo docker exec chongming-mosquitto mosquitto_sub -p 1883 -t '$SYS/broker/version' -W 2 -C 1
+                                                                        # 期望打印版本号
+```
+
+### 接入 chongming 说明
+
+**Zenoh Router**：项目 [zenoh_config.json5](../config/zenoh_config.json5) 默认以 `peer` 模式连接 `tcp/127.0.0.1:7447`。本 router 容器把 7447 映射到宿主机，同机部署时应用即可直接连到该 router；若跨机部署，需把 `connect.endpoints` 改为 router 机器地址。
+
+**Mosquitto**：项目 [config.toml](../config.toml) 默认 `use_embedded_broker = true`（内嵌 amqtt）。要切到本外部 broker，需改为：
+
+```toml
+[development.mqtt]
+enabled = true
+host = "127.0.0.1"
+port = 1883
+use_embedded_broker = false
+```
+
+---
+
+## 2.5 Caddy 反向代理（本地 IP + 自签证书）
+
+Caddy 作为统一 HTTP/HTTPS 入口，反代三个 Web 服务：
+
+| 入口域名 | 反向代理到 |
+|----------|-----------|
+| `gateway.chongming.local` | 宿主机 chongming Web（`host.docker.internal:8000`，systemd 托管） |
+| `s3.chongming.local` | MinIO S3 API（容器 `minio:9000`） |
+| `minio.chongming.local` | MinIO Web Console（容器 `minio:9001`） |
+
+> 采用**本地 IP + 自签证书**方案：三站均使用 `tls internal`，由 Caddy 内置根证书签发
+> 自签证书，**不走公网 ACME**，适合内网/测试环境。
+
+### 部署
+
+```bash
+cd deploy
+sudo docker compose up -d caddy
+```
+
+首次会自动拉取 `caddy:2-alpine` 镜像；Caddyfile 改动后：
+`sudo docker compose exec caddy caddy reload --config /etc/caddy/Caddyfile`
+
+### 访问方式（重要）
+
+1. 先把三个本地域名指向机器 IP，追加到**访问端**（含宿主机、内网其它机器）的 `/etc/hosts`：
+
+```
+<本机IP>  gateway.chongming.local s3.chongming.local minio.chongming.local
+```
+
+2. 浏览器访问（会提示证书不受信任，自签属正常，添加例外即可）：
+   - `https://gateway.chongming.local` —— chongming Web
+   - `https://minio.chongming.local` —— MinIO Console（账号见 [.env](.env)）
+   - S3 SDK 配置 Endpoint 为 `https://s3.chongming.local`
+
+命令行自测（自签需 `-k`）：
+
+```bash
+curl -k https://minio.chongming.local/minio/health/live   # 期望结果含账号名（匿名则 403 也正常）
+```
+
+> 说明：MinIO 容器仍保留 9000/9001 对宿主端口映射；若只想统一走 Caddy 入口，
+> 可删除 compose 中 minio 的 `ports` 段。
+
+---
+
+## 3. systemd 管理 chongming 应用
+
+[chongming.service](chongming.service) 以非特权用户 `linaro` 运行打包后的 chongming 二进制（Nuitka 产物，`/data/chongming`）。
+
+安装：
+
+```bash
+sudo cp deploy/chongming.service /etc/systemd/system/chongming.service
+sudo systemctl daemon-reload
+sudo systemctl enable --now chongming
+```
+
+常用运维命令：
+
+```bash
+sudo systemctl status chongming      # 状态
+sudo systemctl restart chongming     # 重启（优雅排空，最长 30s）
+journalctl -u chongming -f           # 系统日志；应用自身日志在 /data/chongming/logs/
+```
+
+> 注意：安装目录、用户、worker 数等以 service 文件注释为准；如部署路径不同，
+> 需同步修改 `WorkingDirectory` / `ExecStart`。

 ### 5.2 多实例共享缓存 `[workers.cache]`
 
-多实例部署（多进程/多机）**必须**启用 Redis 共享缓存，使副本数与配置跨实例收敛为单一事实来源：
+Rust 进程插件支持两种共享缓存后端（schema 与 Python `chongming-cache` 完全一致）：
 
-```toml
-[workers.cache]
-backend = "redis"             # 仅支持 redis（Python 本地 diskcache 格式 Rust 不可读）
-url = "redis://127.0.0.1:6379/0"
-launch_worker_count = "cache" # 缓存为 count 单一事实来源
-```
+1. **本机共享 `sqlite`（feature `local-cache`）**：同一份 SQLite 文件由 Python 与 Rust 读写，
+   实现单机多实例/跨语言收敛，无需 Redis。需 `cargo build --features local-cache`：
+   ```toml
+   [workers.cache]
+   backend = "sqlite"          # schema 与 Python SqliteBackend 一致（旧名 diskcache 兼容）
+   path = "./cache_data/cache.db"   # 与网关该实例 `[cache].path` 指向同一文件
+   launch_worker_count = "cache"
+   ```
+2. **跨主机 `redis`（feature `redis-cache`）**：多机部署必须用 Redis 共享缓存：
+   ```toml
+   [workers.cache]
+   backend = "redis"
+   url = "redis://127.0.0.1:6379/0"
+   prefix = "chongming:"         # 与网关 config.toml [cache].redis_prefix 对齐（缺省空）
+   launch_worker_count = "cache"
+   ```
+   未指定 backend（缺省）时 Rust 走 `Cache::None`，退化为本地 toml 语义。
+
+> `prefix` 必须与网关 `[cache].redis_prefix`（如 `"chongming:"`）一致，Rust 插件才会读写
+> 与网关同一批共享键。若网关未设前缀可省略。缓存值统一以 JSON 存储（Python 侧用
+> orjson、Rust 侧用 serde_json），**任意键**均可跨语言互通；与 Rust 共享的键请使用
+> JSON 兼容类型（dict/list/int/str/bool/null）。
 
 编译启用：`bash build.sh dist "redis-cache"`（或 Cargo 依赖加 `chongming-worker-rs/redis-cache`）。
 未配置时单实例直接读写本地 `config.toml`（默认无缓存），行为一致。
