There are two deployment methods: docker compose deployment and source code deployment

Docker Compose deployment

Prerequisites

See Install Docker and Install Docker Compose to complete the Docker and Docker Compose installation. Use the docker-compose or docker compose command depending on your Docker Compose version. See Installing the NVIDIA Container Toolkit to enable GPU support in Docker containers.

Clone NexusAI

Clone the NexusAI source code to your local environment

git clone https://github.com/EDEAI/NexusAI.git

Initialize the model directory and storage directory

cd NexusAI
mkdir -p models storage
chmod 777 storage

Cloning the Embedding and Reranker models for offline mode

# Enter the model directory
cd models

# Clone all models
apt install git-lfs
git clone https://huggingface.co/GanymedeNil/text2vec-large-chinese
git clone https://huggingface.co/BAAI/bge-reranker-v2-m3

Milvus Authentication

If you want to enable Milvus authentication, refer to Milvus Authentication to set up Milvus authentication and modify the milvus-standalone service settings in docker-compose.yml

Launch NexusAI

Enter the Docker directory of the NexusAI source code

cd NexusAI/docker

Copy docker-compose.yml and replace SANDBOX_HOST with the real IP address of the host

cp docker-compose.yml.template docker-compose.yml

Start all Docker containers

docker-compose up -d

After running the command, you should see output similar to the following, showing the status of all containers

Finally, you can check whether all containers are running normally

docker-compose ps

In the output below, you can see three business service containers nexusai-docker-multi-service nexusai-docker-web, and the rest are basic service containers

Source code deployment

Prerequisites

Before deploying NexusAI locally, we need to deploy the following basic services:

Clone the NexusAI source code to your local environment

Milvus Authentication

If you want to enable Milvus authentication, refer to Milvus Authentication to set up Milvus authentication.

Server deployment

Initialize the model directory and storage directory

Cloning the Embedding and Reranker models for offline mode

Initialize the database

cd NexusAI

# Login to mariadb
mariadb -u root -p

# Create a database, user, and grant permissions
CREATE DATABASE nexus_ai DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
CREATE USER 'nexus_ai'@'%' IDENTIFIED BY '<mysqlpwd>';
GRANT ALL PRIVILEGES ON nexus_ai.* TO 'nexus_ai'@'%';
FLUSH PRIVILEGES;
EXIT;

# Data import
mariadb -u nexus_ai -p<mysqlpwd> nexus_ai < docker/mysql/db_init/nexus_ai.sql

Create and activate the basic conda environment. The default Python version we use is 3.10.13, We recommend using Python version >= 3.10 and <= 3.12 for compatibility.

cd NexusAI
conda create --name nexus_ai python=3.10.13 --no-default-packages
conda activate nexus_ai
conda env update -f conda/nexus_ai.yml

Copy .env and modify the .env configuration items as needed, For configuration instructions, refer to docker-compose.yml configuration instructions

cp .env.template .env

Configure icon access rules through nginx

server {
    listen 9475; # The port should be consistent with ICON_URL in `.env`

    location /tool_icon {
        alias NexusAI/assets/tool; # Fill in the real path of the project
        try_files $uri $uri/ =404;
    }
}

Restart nginx

systemctl restart nginx

Start the sandbox container

# The docker image tag should be consistent with the configuration in `docker-compose.yml`
docker pull edeai/sandbox:<tag>

# SANDBOX_PORT should be consistent with `.env`
# The mounted local storage directory should be changed to the real path
# SANDBOX_FASTAPI_WORKERS: The number of workers for the sandbox service
docker run -d --privileged -p <SANDBOX_PORT>:8001 -v NexusAI/storage:/storage -e SANDBOX_FASTAPI_WORKERS=2 edeai/sandbox:<tag>

Note that before executing all the Python scripts below, you must first execute conda activate nexus_ai

Start the API service

python app.py

Start Celery asynchronous task service

python celery_app.py

Start the websocket service

python websocket.py

Start roundtable service

python task/chatroom_run.py

Start the workflow service

python task/workflow_run.py

WEB deployment

Go to the web directory and copy envConfig.ts, Modify the envConfig.ts configuration items as needed. For configuration instructions, refer to docker-compose.yml configuration instructions

cd web
cp config/envConfig.ts.template config/envConfig.ts

Install dependency packages

npm install

Start the web service

# You can also use other instructions in `package.json:scripts`
npm run start

Visit NexusAI

http://127.0.0.1:9471

When you visit for the first time, you can log in using the following initial administrator account

Email:
admin@nexusai.com

Password:
nexusaipwd

Note: To update the initial administrator password

python scripts/init_admin_password.py

Pull NexusAI

Pull the updated content from the git repository

cd NexusAI
git pull origin main

If conda/nexus_ai.yml is updated, the conda environment needs to be updated

conda activate nexus_ai
conda env update -f conda/nexus_ai.yml

If there are .sql file updates in the docker/multi_service/db_migrations directory, you need to update the database

conda activate nexus_ai
python scripts/migrations.py

If the image corresponding to docker-compose.yml:sandbox:image is updated, you need to restart the sandbox container

# Find the running sandbox container
docker ps | grep sandbox

# Stop the container by the corresponding container id
docker stop <container_id>
# Delete the container by the corresponding container id
docker rm <container_id>
# Delete old images
docker rmi edeai/sandbox:<old tag>

# The docker image tag should be consistent with the configuration in `docker-compose.yml`
docker pull edeai/sandbox:<new tag>

# SANDBOX_PORT should be consistent with `.env`
# The mounted local storage directory should be changed to the real path
# SANDBOX_FASTAPI_WORKERS: The number of workers for the sandbox service
docker run -d --privileged -p <SANDBOX_PORT>:8001 -v NexusAI/storage:/storage -e SANDBOX_FASTAPI_WORKERS=2 edeai/sandbox:<new tag>

Note that the updated content in .env.template is synchronized to .env, and the updated content in web/config/envConfig.ts.template is synchronized to web/config/envConfig.ts
