gDHT

A distributed self-host DHT torrent search suite

demo site: guo.sh

Introduction

gDHT is a search engine suite that allows user to host their own torrent search engine. There are four major components of the suite: crawler, server, ElasticSearch, and web. The distributed crawler will monitor the traffic on DHT network to collect meta information of the torrent and then sent collected information to server via gRPC. Upon on receiving the information, the server will push them into Redis message queue and asynchronously process (Ex. filter unwanted torrent) and index them into ElasticSearch. Finally, you can search the torrent information at the React web interface.

Getting Started

Nginx

The nginx server is bound to YOURDOMAIN.COM by default. If you want to host your own torrent search engine, your can change Nginx's environment variable URL in docker-compose.yml.

Golang Crawler

You can leave the setting in docker-compose.yml unchanged if you run the suite with only one crawler. However, to add additional crawler to the system, change environment variable address under crawler to master-server-ip-address:50051.

ElasticSearch Security

The security features of the ElasticSearch is enabled by default. To ensure that crawler and web function normally, you need to create two user: web and crawler. Notice that crawler must have permission to write and read index and web must have permission to read index. Once you created those two users, you can pass the username and password to Golang crawler via the environment variables in docker-compose.yml. To pass username and password of web to web, change REACT_APP_USERNAME and REACT_APP_PASSWORD under web/src/.env. For more information on how to set up ElasticSearch, check those two articles Configuring security in Elasticsearchedit and Getting started with Elasticsearch security.

Then, start the server by

docker-compose build
docker-compose up
