The first way is to configure a completely independent working environment for each instance. This requires creating a separate working directory for each instance and placing a dedicated `.env` configuration file in that directory. The server listening ports in the configuration files of different instances cannot be the same. Then, you can start the service by running `lightrag-server` in the working directory. diff --git a/lightrag/llm/Readme.md b/lightrag/llm/Readme.md deleted file mode 100644 index fc00d071..00000000 --- a/lightrag/llm/Readme.md +++ /dev/null @@ -1,156 +0,0 @@ - -1. **LlamaIndex** (`llm/llama_index.py`): - - Provides integration with OpenAI and other providers through LlamaIndex - - Supports both direct API access and proxy services like LiteLLM - - Handles embeddings and completions with consistent interfaces - - See example implementations: - - [Direct OpenAI Usage](../../examples/lightrag_llamaindex_direct_demo.py) - - [LiteLLM Proxy Usage](../../examples/lightrag_llamaindex_litellm_demo.py) - -
