路径。适合一次性、临时使用的场景。 + +### 3.2 软链到 PATH（推荐给运维 / 长期使用） + +不论脚本来源（git clone 出来的仓库 / `npm install` 装的包 / 自定义部署目录），先把脚本路径**算出来存到一个变量里**，再统一做软链。这样无需关心你把仓库放在 `~/code/`、`/opt/`、还是别的什么地方。 + +```bash +# 第一步：定位

/usr/local/bin/install-memory-tencentdb +} +``` + +之后直接 `memory-tencentdb-ctl …` / `install-memory-tencentdb …`。 + +> **为什么不直接用 `npm bin` 注册？** 这两个脚本是运维工具而不是包的核心 API，主仓库希望用户**显式**完成 PATH 注册（避免无意中污染全局命令空间，并避免 npm 卸载时静默移除运维入口）。 + +## 4. 生命周期管理（两种模式通用） + +```bash +memory-tencentdb-ctl start # 若 :8420 已占用会直接返回；否则后台 spawn，等待 /health 通过 +memory-tencentdb-ctl stop # 先 SIGTERM，5s 内未退则 SIGKILL

+ +- JSON 写入点：`$.llm.{baseUrl, apiKey, model}`。 +- env 文件写入（仅 `--hermes`）：`TDAI_LLM_*` 及 `MEMORY_TENCENTDB_LLM_*` 别名（Python provider 的 `get_config_schema()` 会读后者）。 + +### 5.2 Embedding + +默认关闭（`provider=none`）。启用远端 OpenAI 兼容服务： + +```bash +memory-tencentdb-ctl config embedding \ + --provider openai \ + --api-key "sk-xxxx" \ + --base-url "https://api.openai.com/v1" \ + --model "text-embedding-3-small" \ + --dimensions 1536 \ + --restart + +# 关闭 embedding（退化为 BM25/关键词召回） +memory-tencentdb-ctl config embedding --provider none --restart +``` + +- JSON 写入点：`$.memory.embedding.{provider, baseUrl, apiKey, model, dimensions, enabled, proxyUrl?}`。 +- `qclaw` provider 额外要求 `--proxy-url`。 +- 校验规则与 `src/config.ts` 的 `parseConfig()` 对齐：`dimensions` 为正整数，非 `none` 必须带 `apiKey/baseUrl/model/dimensions`；缺项直接报错不写半残 JSON。 + +### 5.3 VectorDB（Tencent Cloud VDB / tcvdb） + +```bash +memory-tencentdb-ctl config vdb \ + --url "http://xxx-vdb.tencentclb.com:8100" \ + --username root \ + --api-key "YOUR-VDB-API-KEY" \ + --database "openclaw_memory" \ + --alias "primary" \ + --embedding-model "bge-large-zh" \ + --ca-pem "/etc/ssl/vdb-ca.pem" \ + --restart +``` + +- JSON 写入点：`$.memory.tcvdb.{url, username, apiKey, database, alias?, caPemPath?, embeddingModel?}`。 +- 默认同时把 `$.memory.storeBackend` 切到 `"tcvdb"`；只想预埋配置先不切，加 `--no-set-backend`。 +- `--ca-pem` 只写路径不复制文件；脚本会校验可读性。 + +### 5.4 退回本地 SQLite（关闭 VDB 后端） + +```bash +# 默认：保留 memory.tcvdb 凭据（方便随时再切回去），仅把 storeBackend 改回 sqlite +memory-tencentdb-ctl config vdb-off --restart + +# 同时把腾讯云 VDB 的 url / apiKey / database 等凭据从 JSON 中清掉 +memory-tencentdb-ctl config vdb-off --purge-creds --restart +``` + +- JSON 写入点：把 `$.memory.storeBackend` 设为 `"sqlite"`；`--purge-creds` 时额外删除整段 `$.memory.tcvdb`。 +- `$.llm` / `$.memory.embedding` 等其它顶级段**完全保留**，hermes 侧 `memory.provider` **不动**（仍是 `memory_tencentdb`，只是它内部存储退回 sqlite）。 +- 配置文件不存在时给出 `warn` 并写入仅含 `{"memory":{"storeBackend":"sqlite"}}` 的最小配置。 +- 与 `config vdb` 完全镜像：可与 `--dry-run` / `--restart` 组合使用。 + +### 5.5 查看当前配置 + +```bash +memory-tencentdb-ctl config show +``` + +- 打印 `tdai-gateway.json`，`apiKey`/`password`/`token` 字段自动脱敏为 ``。 +- hermes 模式下额外打印 `$HERMES_HOME/env.d/memory-tencentdb-*.sh`（API key 也会脱敏），可直接贴工单。 + +## 6. 打通 hermes（仅 `--hermes` 模式） + +```bash +memory-tencentdb-ctl --hermes enable-hermes-memory +``` + +幂等：把 `$HERMES_HOME/config.yaml` 的 `memory:` 段的 `provider:` 改成 `memory_tencentdb`（不存在则新增整段）。改完后重启 hermes： + +```bash +source "$HERMES_HOME/env.d/memory-tencentdb-llm.sh" +pkill -f hermes-agent || true +hermes +``` + +> **关于写入策略**：脚本采用"格式保真"双路径，**永不重写整个 YAML**： +> +> 1. **首选**：检测到 [`ruamel.yaml`](https://yaml.readthedocs.io/) 时走 round-trip，完整保留注释、键序、引号、缩进风格（推荐 `pip install --user ruamel.yaml` 享受最佳保真度，**非必装**）； +> 2. **降级**：未安装 ruamel 时走最小化原位行编辑——只重写 `provider:` 那一行，缩进直接从同段已有兄弟键的前缀**逐字符拷贝**（零猜测、零格式破坏）； +> 3. 若 `memory:` 段不存在，则在文件末尾追加最小段，缩进从文档其它顶级段的子键拓印。 +> +> 实测对真实 `~/.hermes/config.yaml` 做 byte-for-byte diff，除 `provider` 值本身外其余字节完全一致。 + +非 hermes 模式下调用该命令会直接报错退出。 + +> 想反过来"保留 hermes provider 不变，仅让 TDAI 内部存储退回 sqlite"，用 §5.4 的 `config vdb-off` 即可（不需要也**不要**改 hermes 的 `memory.provider`）。 + +## 7. 典型使用流程 + +### 场景 A：Gateway 独立部署（不使用 hermes） + +```bash +# 1) 安装 +# INSTALL_SCRIPT 的取值方式见上文 3.2 节（git rev-parse / npm root / 手填均可） +# 例如从 git 仓库根：INSTALL_SCRIPT="$(git rev-parse

--database openclaw_memory + +# 3) 启动 + 自检 +memory-tencentdb-ctl start +memory-tencentdb-ctl status +memory-tencentdb-ctl health # 预期: {"status":"ok",...} +``` + +### 场景 B：集成 hermes + +```bash +# 1) 安装（与场景 A 相同；INSTALL_SCRIPT 由上文 3.2 节算出） +bash "$INSTALL_SCRIPT" + +# 2) 全程加 --hermes（或 export MEMORY_TENCENTDB_MODE=hermes 一次） +memory-tencentdb-ctl --hermes config llm --api-key "sk-..." --base-url "https://api.openai.com/v1" --model gpt-4o +memory-tencentdb-ctl --hermes config embedding --provider openai --api-key "sk-..." \ + --base-url "https://api.openai.com/v1" \ + --model text-embedding-3-small --dimensions 1536 +memory-tencentdb-ctl --hermes config vdb --url "http://xxx:8100" --api-key "..." --database openclaw_memory + +# 3) 启动 Gateway（通常由 hermes supervisor 托管，这里是手动兜底） +memory-tencentdb-ctl --hermes start +memory-tencentdb-ctl --hermes status + +# 4) 在 hermes config 里启用 provider，并重启 hermes +memory-tencentdb-ctl --hermes enable-hermes-memory +source "$HERMES_HOME/env.d/memory-tencentdb-llm.sh" +pkill -f hermes-agent ; hermes +``` + +如果嫌 `--hermes` 每次都要带，可以： + +```bash +export MEMORY_TENCENTDB_MODE=hermes +``` + +之后所有调用自动切到 hermes 模式，命令行无需再加 `--hermes`。 + +### 场景 C：临时把 TDAI 的存储退回 sqlite（保留 hermes 集成） + +适用于 VDB 不可达 / 排障 / 离线开发等场景：希望 hermes 端 `memory.provider` 仍是 `memory_tencentdb`，但让 Gateway 改用本地 SQLite 落盘。 + +```bash +# (A) 默认：保留 memory.tcvdb 凭据，仅把 storeBackend 切回 sqlite +memory-tencentdb-ctl config vdb-off --restart + +# (B) 排障结束想切回 vdb：当前需要重新跑一次 config vdb（必填项需重新提供， +# 即使 JSON 里凭据还在；脚本是基于必填校验的"重新声明"语义，不是 toggle） +memory-tencentdb-ctl config vdb \ + --url "http://xxx-vdb.tencentclb.com:8100" \ + --api-key "<你的 KEY>" \ + --database "openclaw_memory" \ + --restart + +# (C) 彻底放弃 vdb：清掉凭据 +memory-tencentdb-ctl config vdb-off --purge-creds --restart +``` + +> 之所以 (B) 不提供"零参数 vdb-on"，是因为原 `config vdb` 子命令把 `--url/--api-key/--database` 设为强校验，避免用户拼装出半残配置；如果你希望把"已存的凭据重新激活"也做成单命令，告诉维护者补一个 `config vdb-on` 即可（实现方式与 `vdb-off` 完全镜像）。 + +> **不要**为了"切回 sqlite"去改 `~/.hermes/config.yaml` 的 `memory.provider`！hermes 看到的依然是 `memory_tencentdb` provider，存储后端切换是 Gateway 内部的事，对 hermes 完全透明。 + +## 8. 全局选项 & 调试技巧 + +- 所有写操作支持 `--dry-run`（放在命令最前），会打印将要写入的内容但不落盘： + ```bash + memory-tencentdb-ctl --dry-run config llm --api-key k --base-url https://x --model m + ``` +- 敏感文件权限一律 `0600`；`env.d/memory-tencentdb-llm.sh` 含明文 API key，**不要** commit。 +- 启动失败：`memory-tencentdb-ctl logs err 200` 查看 stderr；手动前台跑一遍更容易看到报错： + ```bash + cd "$TDAI_INSTALL_DIR" && npx tsx src/gateway/server.ts + ``` +- 端口冲突：`MEMORY_TENCENTDB_GATEWAY_PORT=18420 memory-tencentdb-ctl restart`。 +- 验证 hermes 有没有吃到新 env（hermes 模式）： + ```bash + tr '\0' '\n' < /proc/$(pgrep -n hermes-agent)/environ | grep -E 'TDAI_|MEMORY_TENCENTDB_' + ``` + +## 9. 退出码 + +| 码 | 含义 | +|---|---| +| 0 | 成功 | +| 1 | 参数错误 / 业务校验失败（如 `--base-url` 非 http(s)；在 standalone 下调 hermes 专属命令） | +| 2 | 写盘失败（磁盘满、权限不足等） | +| 127 | 依赖缺失（`python3` / `node` / `npx`） | + +--- + +要封装成 systemd unit，基于 `memory-tencentdb-ctl start` / `memory-tencentdb-ctl stop` 写 `Type=forking` 的 service 即可（Gateway 是无状态 HTTP sidecar，不依赖 systemd
