MinerU PDF document parsing is available starting from v0.22.0. RAGFlow supports MinerU (>= 2.6.3) as an optional PDF parser with multiple backends. RAGFlow acts only as a **remote client** for MinerU, calling the MinerU API to parse documents, reading the returned output files, and ingesting the parsed content. To use this feature:
:::
1. Prepare MinerU:
1. Prepare a reachable MinerU API service (FastAPI server).
2. Configure RAGFlow with the remote MinerU settings (env or UI model provider):
- `MINERU_APISERVER`: MinerU API endpoint, for example `http://mineru-host:8886`.
- `MINERU_BACKEND`: MinerU backend, defaults to `pipeline` (supports `vlm-http-client`, `vlm-transformers`, `vlm-vllm-engine`, `vlm-mlx-engine`, `vlm-vllm-async-engine`, `vlm-lmdeploy-engine`).
- `MINERU_SERVER_URL`: (optional) For `vlm-http-client`, the downstream vLLM HTTP server, for example `http://vllm-host:30000`.
- `MINERU_OUTPUT_DIR`: (optional) Local directory to store MinerU API outputs (zip/JSON) before ingestion.
- `MINERU_DELETE_OUTPUT`: Whether to delete temporary output when a temp dir is used (`1` deletes temp outputs; set `0` to keep).
3. In the web UI, navigate to the **Configuration** page of your dataset. Click **Built-in** in the **Ingestion pipeline** section, select a chunking method from the **Built-in** dropdown, which supports PDF parsing, and select **MinerU** in **PDF parser**.
4. If you use a custom ingestion pipeline instead, provide the same MinerU settings and select **MinerU** in the **Parsing method** section of the **Parser** component.
- **If you deploy RAGFlow from source**, install MinerU into an isolated virtual environment (recommended path: `$HOME/uv_tools`):
```bash
mkdir -p "$HOME/uv_tools"
cd "$HOME/uv_tools"
uv venv .venv
source .venv/bin/activate
uv pip install -U "mineru[core]" -i https://mirrors.aliyun.com/pypi/simple
# or
# uv pip install -U "mineru[all]" -i https://mirrors.aliyun.com/pypi/simple
```
- **If you deploy RAGFlow with Docker**, you usually only need to turn on MinerU support in `docker/.env`:
```bash
# docker/.env
...
USE_MINERU=true
...
```
Enabling `USE_MINERU=true` will internally perform the same setup as the manual configuration (including setting the MinerU executable path and related environment variables). You only need the manual installation above if you are running from source or want full control over the MinerU installation.
2. Start RAGFlow with MinerU enabled:
- **Source deployment** – in the RAGFlow repo, export the key MinerU-related variables and start the backend service:
```bash
# in RAGFlow repo
export MINERU_EXECUTABLE="$HOME/uv_tools/.venv/bin/mineru"
export MINERU_DELETE_OUTPUT=0 # keep output directory
export MINERU_BACKEND=pipeline # or another backend you prefer
source .venv/bin/activate
export PYTHONPATH=$(pwd)
bash docker/launch_backend_service.sh
```
- **Docker deployment** – after setting `USE_MINERU=true`, restart the containers so that the new settings take effect:
```bash
# in RAGFlow repo
docker compose -f docker/docker-compose.yml restart
```
3. Restart the ragflow-server.
:::note
All MinerU environment variables are optional. If set, RAGFlow will auto-provision a MinerU OCR model for the tenant on first use with these values. To avoid auto-provisioning, configure MinerU solely through the UI and leave the env vars unset.
