🔎 System Architecture
🎬 Get Started
📝 Prerequisites
- CPU >= 4 cores
- RAM >= 16 GB
- Disk >= 50 GB
- Docker >= 24.0.0 & Docker Compose >= v2.26.1
- gVisor: Required only if you intend to use the code executor (sandbox) feature of RAGFlow.
Tip
If you have not installed Docker on your local machine (Windows, Mac, or Linux), see Install Docker Engine.
🚀 Start up the server
-
Ensure
vm.max_map_count>= 262144:To check the value of
vm.max_map_count:$ sysctl vm.max_map_countReset
vm.max_map_countto a value at least 262144 if it is not.# In this case, we set it to 262144: $ sudo sysctl -w vm.max_map_count=262144This change will be reset after a system reboot. To ensure your change remains permanent, add or update the
vm.max_map_countvalue in /etc/sysctl.conf accordingly:vm.max_map_count=262144 -
Clone the repo:
$ git clone https://github.com/infiniflow/ragflow.git -
Start up the server using the pre-built Docker images:
Caution
All Docker images are built for x86 platforms. We don't currently offer Docker images for ARM64. If you are on an ARM64 platform, follow this guide to build a Docker image compatible with your system.
The command below downloads the
v0.21.1-slimedition of the RAGFlow Docker image. See the following table for descriptions of different RAGFlow editions. To download a RAGFlow edition different fromv0.21.1-slim, update theRAGFLOW_IMAGEvariable accordingly in docker/.env before usingdocker composeto start the server.
$ cd ragflow/docker
# Use CPU for embedding and DeepDoc tasks:
$ docker compose -f docker-compose.yml up -d
# To use GPU to accelerate embedding and DeepDoc tasks:
# sed -i '1i DEVICE=gpu' .env
# docker compose -f docker-compose.yml up -d
| RAGFlow image tag | Image size (GB) | Has embedding models? | Stable? |
|---|---|---|---|
| v0.21.1 | ≈9 | ✔️ | Stable release |
| v0.21.1-slim | ≈2 | ❌ | Stable release |
| nightly | ≈2 | ❌ | Unstable nightly build |
Note: Starting with
v0.22.0, we ship only the slim edition and no longer append the -slim suffix to the image tag.
-
Check the server status after having the server up and running:
$ docker logs -f docker-ragflow-cpu-1The following output confirms a successful launch of the system:
____ ___ ______ ______ __ / __ \ / | / ____// ____// /____ _ __ / /_/ // /| | / / __ / /_ / // __ \| | /| / / / _, _// ___ |/ /_/ // __/ / // /_/ /| |/ |/ / /_/ |_|/_/ |_|\____//_/ /_/ \____/ |__/|__/ * Running on all addresses (0.0.0.0)If you skip this confirmation step and directly log in to RAGFlow, your browser may prompt a
network anormalerror because, at that moment, your RAGFlow may not be fully initialized. -
In your web browser, enter the IP address of your server and log in to RAGFlow.
With the default settings, you only need to enter
http://IP_OF_YOUR_MACHINE(sans port number) as the default HTTP serving port80can be omitted when using the default configurations. -
In service_conf.yaml.template, select the desired LLM factory in
user_default_llmand update theAPI_KEYfield with the corresponding API key.See llm_api_key_setup for more information.
The show is on!
🔧 Configurations
When it comes to system configurations, you will need to manage the following files:
- .env: Keeps the fundamental setups for the system, such as
SVR_HTTP_PORT,MYSQL_PASSWORD, andMINIO_PASSWORD. - service_conf.yaml.template: Configures the back-end services. The environment variables in this file will be automatically populated when the Docker container starts. Any environment variables set within the Docker container will be available for use, allowing you to customize service behavior based on the deployment environment.
- docker-compose.yml: The system relies on docker-compose.yml to start up.
The ./docker/README file provides a detailed description of the environment settings and service configurations which can be used as
${ENV_VARS}in the service_conf.yaml.template file.
To update the default HTTP serving port (80), go to docker-compose.yml and change 80:80
to <YOUR_SERVING_PORT>:80.
Updates to the above configurations require a reboot of all containers to take effect:
$ docker compose -f docker-compose.yml up -d
Switch doc engine from Elasticsearch to Infinity
RAGFlow uses Elasticsearch by default for storing full text and vectors. To switch to Infinity, follow these steps:
-
Stop all running containers:
$ docker compose -f docker/docker-compose.yml down -v
Warning
-vwill delete the docker container volumes, and the existing data will be cleared.
-
Set
DOC_ENGINEin docker/.env toinfinity. -
Start the containers:
$ docker compose -f docker-compose.yml up -d
Warning
Switching to Infinity on a Linux/arm64 machine is not yet officially supported.
🔧 Build a Docker image without embedding models
This image is approximately 2 GB in size and relies on external LLM and embedding services.
git clone https://github.com/infiniflow/ragflow.git
cd ragflow/
docker build --platform linux/amd64 -f Dockerfile -t infiniflow/ragflow:nightly .
🔨 Launch service from source for development
-
Install
uvandpre-commit, or skip this step if they are already installed:pipx install uv pre-commit -
Clone the source code and install Python dependencies:
git clone https://github.com/infiniflow/ragflow.git cd ragflow/ uv sync --python 3.10 # install RAGFlow dependent python modules uv run download_deps.py pre-commit install -
Launch the dependent services (MinIO, Elasticsearch, Redis, and MySQL) using Docker Compose:
docker compose -f docker/docker-compose-base.yml up -dAdd the following line to
/etc/hoststo resolve all hosts specified in docker/.env to127.0.0.1:127.0.0.1 es01 infinity mysql minio redis sandbox-executor-manager -
If you cannot access HuggingFace, set the
HF_ENDPOINTenvironment variable to use a mirror site:export HF_ENDPOINT=https://hf-mirror.com -
If your operating system does not have jemalloc, please install it as follows:
# Ubuntu sudo apt-get install libjemalloc-dev # CentOS sudo yum install jemalloc # OpenSUSE sudo zypper install jemalloc # macOS sudo brew install jemalloc -
Launch backend service:
source .venv/bin/activate export PYTHONPATH=$(pwd) bash docker/launch_backend_service.sh -
Install frontend dependencies:
cd web npm install -
Launch frontend service:
npm run devThe following output confirms a successful launch of the system:
-
Stop RAGFlow front-end and back-end service after development is complete:
pkill -f "ragflow_server.py|task_executor.py"
