Congratulations on taking the first step towards unleashing the power of Milvus, the world’s most advanced open-source vector database! Building Milvus from source code can be a thrilling experience, but it can also be daunting for those new to the game. Fear not, dear reader, for we’re about to embark on a thrilling adventure to get Milvus up and running in no time!
Before We Dive In
Before we start, make sure you have the following prerequisites in place:
- A compatible Linux or macOS system (Windows is not supported for building from source)
- Docker installed and running on your system
- A C++ compiler (e.g., GCC) and the required dependencies installed
- The Milvus source code downloaded and extracted to a directory on your system
Step 1: Build Milvus from Source Code
Now that we have our prerequisites in place, let’s build Milvus from source code. This process can take some time, so grab a cup of coffee and get comfortable!
cd /path/to/milvus/source/code cmake . make -j8
The above commands will configure and build Milvus using the CMake build system. The -j8 flag tells the compiler to use 8 threads, which can significantly speed up the build process.
Step 2: Build Milvus Docker Image
Once the build process is complete, we need to create a Docker image for Milvus. This will allow us to run Milvus in a containerized environment.
docker build -t milvus:latest .
The above command tells Docker to build an image with the tag milvus:latest using the Dockerfile in the current directory.
Step 3: Start Milvus
The moment of truth has finally arrived! Let’s start Milvus and get it up and running.
docker run -d --name milvus -p 19530:19530 milvus:latest
This command starts a new Docker container from the milvus:latest image and maps port 19530 on the host machine to port 19530 in the container.
Step 4: Verify Milvus is Running
To verify that Milvus is running correctly, we can use the Milvus CLI tool to connect to the server and perform a simple query.
docker exec -it milvus milvus cli -h 127.0.0.1 -p 19530
This command opens an interactive shell where we can issue Milvus commands. Let’s try a simple query to verify that everything is working as expected:
milvus> show collections
If everything is set up correctly, you should see an empty list of collections. Congratulations, you’ve successfully started Milvus from source code!
Troubleshooting Common Issues
Don’t panic if you encounter issues during the build or startup process! Here are some common problems and their solutions:
| Issue | Solution |
|---|---|
| Build fails due to missing dependencies | Install the required dependencies (e.g., GCC, cmake) and retry the build process. |
| Docker image build fails | Check the Dockerfile for errors or syntax issues. You can also try rebuilding the image with the --no-cache flag. |
| Milvus fails to start | Check the Docker container logs for errors. You can do this by running docker logs -f milvus. |
What’s Next?
Now that you’ve successfully started Milvus from source code, the possibilities are endless! You can explore the Milvus documentation to learn more about its features and capabilities. Some exciting next steps include:
