## 🔎 System Architecture
## 🎬 Get Started
### 📝 Prerequisites
- CPU >= 4 cores
- RAM >= 16 GB
- Disk >= 50 GB
- Docker >= 24.0.0 & Docker Compose >= v2.26.1
> If you have not installed Docker on your local machine (Windows, Mac, or Linux), see [Install Docker Engine](https://docs.docker.com/engine/install/).
### 🚀 Start up the server
1. Ensure `vm.max_map_count` >= 262144 ([more](./docs/max_map_count.md)):
> To check the value of `vm.max_map_count`:
>
> ```bash
> $ sysctl vm.max_map_count
> ```
>
> Reset `vm.max_map_count` to a value at least 262144 if it is not.
>
> ```bash
> # In this case, we set it to 262144:
> $ sudo sysctl -w vm.max_map_count=262144
> ```
>
> This change will be reset after a system reboot. To ensure your change remains permanent, add or update the `vm.max_map_count` value in **/etc/sysctl.conf** accordingly:
>
> ```bash
> vm.max_map_count=262144
> ```
2. Clone the repo:
```bash
$ git clone https://github.com/infiniflow/ragflow.git
```
3. Build the pre-built Docker images and start up the server:
> Running the following commands automatically downloads the *dev* version RAGFlow Docker image. To download and run a specified Docker version, update `RAGFLOW_VERSION` in **docker/.env** to the intended version, for example `RAGFLOW_VERSION=v0.5.0`, before running the following commands.
```bash
$ cd ragflow/docker
$ chmod +x ./entrypoint.sh
$ docker compose up -d
```
> The core image is about 9 GB in size and may take a while to load.
4. Check the server status after having the server up and running:
```bash
$ docker logs -f ragflow-server
```
_The following output confirms a successful launch of the system:_
```bash
____ ______ __
/ __ \ ____ _ ____ _ / ____// /____ _ __
/ /_/ // __ `// __ `// /_ / // __ \| | /| / /
/ _, _// /_/ // /_/ // __/ / // /_/ /| |/ |/ /
/_/ |_| \__,_/ \__, //_/ /_/ \____/ |__/|__/
/____/
* Running on all addresses (0.0.0.0)
* Running on http://127.0.0.1:9380
* Running on http://x.x.x.x:9380
INFO:werkzeug:Press CTRL+C to quit
```
> If you skip this confirmation step and directly log in to RAGFlow, your browser may prompt a `network anomaly` error because, at that moment, your RAGFlow may not be fully initialized.
5. In your web browser, enter the IP address of your server and log in to RAGFlow.
> With default settings, you only need to enter `http://IP_OF_YOUR_MACHINE` (**sans** port number) as the default HTTP serving port `80` can be omitted when using the default configurations.
6. In [service_conf.yaml](./docker/service_conf.yaml), select the desired LLM factory in `user_default_llm` and update the `API_KEY` field with the corresponding API key.
> See [./docs/llm_api_key_setup.md](./docs/llm_api_key_setup.md) for more information.
_The show is now on!_
## 🔧 Configurations
When it comes to system configurations, you will need to manage the following files:
- [.env](./docker/.env): Keeps the fundamental setups for the system, such as `SVR_HTTP_PORT`, `MYSQL_PASSWORD`, and `MINIO_PASSWORD`.
- [service_conf.yaml](./docker/service_conf.yaml): Configures the back-end services.
- [docker-compose.yml](./docker/docker-compose.yml): The system relies on [docker-compose.yml](./docker/docker-compose.yml) to start up.
You must ensure that changes to the [.env](./docker/.env) file are in line with what are in the [service_conf.yaml](./docker/service_conf.yaml) file.
> The [./docker/README](./docker/README.md) file provides a detailed description of the environment settings and service configurations, and you are REQUIRED to ensure that all environment settings listed in the [./docker/README](./docker/README.md) file are aligned with the corresponding configurations in the [service_conf.yaml](./docker/service_conf.yaml) file.
To update the default HTTP serving port (80), go to [docker-compose.yml](./docker/docker-compose.yml) and change `80:80` to `:80`.
> Updates to all system configurations require a system reboot to take effect:
>
> ```bash
> $ docker-compose up -d
> ```
## 🛠️ Build from source
To build the Docker images from source:
```bash
$ git clone https://github.com/infiniflow/ragflow.git
$ cd ragflow/
$ docker build -t infiniflow/ragflow:dev .
$ cd ragflow/docker
$ chmod +x ./entrypoint.sh
$ docker compose up -d
```
## 🛠️ Launch Service from Source
To launch the service from source, please follow these steps:
1. Clone the repository
```bash
$ git clone https://github.com/infiniflow/ragflow.git
$ cd ragflow/
```
2. Create a virtual environment (ensure Anaconda or Miniconda is installed)
```bash
$ conda create -n ragflow python=3.11.0
$ conda activate ragflow
$ pip install -r requirements.txt
```
If CUDA version is greater than 12.0, execute the following additional commands:
```bash
$ pip uninstall -y onnxruntime-gpu
$ pip install onnxruntime-gpu --extra-index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-12/pypi/simple/
```
3. Copy the entry script and configure environment variables
```bash
$ cp docker/entrypoint.sh .
$ vi entrypoint.sh
```
Use the following commands to obtain the Python path and the ragflow project path:
```bash
$ which python
$ pwd
```
Set the output of `which python` as the value for `PY` and the output of `pwd` as the value for `PYTHONPATH`.
If `LD_LIBRARY_PATH` is already configured, it can be commented out.
```bash
# Adjust configurations according to your actual situation; the two export commands are newly added.
PY=${PY}
export PYTHONPATH=${PYTHONPATH}
# Optional: Add Hugging Face mirror
export HF_ENDPOINT=https://hf-mirror.com
```
4. Start the base services
```bash
$ cd docker
$ docker compose -f docker-compose-base.yml up -d
```
5. Check the configuration files
Ensure that the settings in **docker/.env** match those in **conf/service_conf.yaml**. The IP addresses and ports for related services in **service_conf.yaml** should be changed to the local machine IP and ports exposed by the container.
6. Launch the service
```bash
$ chmod +x ./entrypoint.sh
$ bash ./entrypoint.sh
```
7. Start the WebUI service
```bash
$ cd web
$ npm install --registry=https://registry.npmmirror.com --force
$ vim .umirc.ts
# Modify proxy.target to 127.0.0.1:9380
$ npm run dev
```
8. Deploy the WebUI service
```bash
$ cd web
$ npm install --registry=https://registry.npmmirror.com --force
$ umi build
$ mkdir -p /ragflow/web
$ cp -r dist /ragflow/web
$ apt install nginx -y
$ cp ../docker/nginx/proxy.conf /etc/nginx
$ cp ../docker/nginx/nginx.conf /etc/nginx
$ cp ../docker/nginx/ragflow.conf /etc/nginx/conf.d
$ systemctl start nginx
```
