Before installing Dify, make sure your machine meets the following minimum system requirements:
CPU >= 2 Core
RAM >= 4 GiB
Operating System
Software
Explanation
If you need to use OpenAI TTS, FFmpeg must be installed on the system for it to function properly. For more details, refer to: Link.
Clone Dify
git clone https://github.com/langgenius/dify.git
Before enabling business services, we need to first deploy PostgreSQL / Redis / Weaviate (if not locally available). We can start them with the following commands:
cd docker
cp middleware.env.example middleware.env
docker compose -f docker-compose.middleware.yaml up -d
Server Deployment
API Interface Service
Worker Asynchronous Queue Consumption Service
Installation of the basic environment:
Server startup requires Python 3.11 or 3.12. It is recommended to use pyenv for quick installation of the Python environment.
To install additional Python versions, use pyenv install.
pyenv install 3.11
To switch to the "3.11" Python environment, use the following command:
pyenv global 3.11
Follow these steps :
Navigate to the "api" directory:
cd api
Copy the environment variable configuration file:
cp .env.example .env
Generate a random secret key and replace the value of SECRET_KEY in the .env file:
Dify API service uses Poetry to manage dependencies. You can execute poetry shell to activate the environment.
poetry env use 3.11
poetry install
Perform the database migration:
Perform database migration to the latest version:
poetry shell
flask db upgrade
Start the API server:
flask run --host 0.0.0.0 --port=5001 --debug
output:
* Debug mode: on
INFO:werkzeug:WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
* Running on all addresses (0.0.0.0)
* Running on http://127.0.0.1:5001
INFO:werkzeug:Press CTRL+C to quit
INFO:werkzeug: * Restarting with stat
WARNING:werkzeug: * Debugger is active!
INFO:werkzeug: * Debugger PIN: 695-801-919
Start the Worker service
To consume asynchronous tasks from the queue, such as dataset file import and dataset document updates, follow these steps to start the Worker service on Linux or macOS:
celery -A app.celery worker -P gevent -c 1 --loglevel INFO -Q dataset,generation,mail,ops_trace
If you are using a Windows system to start the Worker service, please use the following command instead:
celery -A app.celery worker -P solo --without-gossip --without-mingle -Q dataset,generation,mail,ops_trace --loglevel INFO
Please visit https://nodejs.org/en/download and choose the installation package for your respective operating system that is v18.x or higher. It is recommended to download the stable version, which includes NPM by default.
Follow these steps :
Enter the web directory
cd web
Install the dependencies.
npm install
Configure the environment variables. Create a file named .env.local in the current directory and copy the contents from .env.example. Modify the values of these environment variables according to your requirements:
# For production release, change this to PRODUCTION
NEXT_PUBLIC_DEPLOY_ENV=DEVELOPMENT
# The deployment edition, SELF_HOSTED or CLOUD
NEXT_PUBLIC_EDITION=SELF_HOSTED
# The base URL of console application, refers to the Console base URL of WEB service if console domain is
# different from api or web app domain.
# example: http://cloud.dify.ai/console/api
NEXT_PUBLIC_API_PREFIX=http://localhost:5001/console/api
# The URL for Web APP, refers to the Web App base URL of WEB service if web app domain is different from
# console or api domain.
# example: http://udify.app/api
NEXT_PUBLIC_PUBLIC_API_PREFIX=http://localhost:5001/api
# SENTRY
NEXT_PUBLIC_SENTRY_DSN=
NEXT_PUBLIC_SENTRY_ORG=
NEXT_PUBLIC_SENTRY_PROJECT=
Build the code
npm run build
Start the web service
npm run start
# or
yarn start
# or
pnpm start
After successful startup, the terminal will output the following information:
ready - started server on 0.0.0.0:3000, url: http://localhost:3000
warn - You have enabled experimental feature (appDir) in next.config.js.
warn - Experimental features are not covered by semver, and may cause unexpected or broken application behavior. Use at your own risk.
info - Thank you for testing `appDir` please leave your feedback at https://nextjs.link/app-feedback
Set the Docker virtual machine (VM) to use a minimum of 2 virtual CPUs (vCPUs) and 8 GB of initial memory. Otherwise, the installation may fail. For more information, please refer to the Docker Desktop installation guide for Mac.
