Install Milvus from Source Code

Software requirements

• Ubuntu 18.04 or higher
• CMake 3.12 or higher

For GPU version, you will also need:

• CUDA 10.0 or higher
• NVIDIA driver 418 or higher

Compilation

Step 1 Install dependencies

$ cd [Milvus root path]/core
$ ./ubuntu_build_deps.sh

Step 2 Build

$ cd [Milvus root path]/core
$ ./build.sh -t Debug
or 
$ ./build.sh -t Release

By default, it will build CPU version. To build GPU version, add -g option

$ ./build.sh -g

When the build is completed, all the stuff that you need in order to run Milvus will be installed under [Milvus root path]/core/milvus.

Launch Milvus server

$ cd [Milvus root path]/core/milvus

Add lib/ directory to LD_LIBRARY_PATH

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:[Milvus root path]/core/milvus/lib

Then start Milvus server:

$ cd scripts
$ ./start_server.sh

To stop Milvus server, run:

$ ./stop_server.sh

Troubleshooting

1. If you encounter the following error when compiling: protocol https not supported or disabled in libcurl. First, make sure you have libcurl4-openssl-dev installed in your system. Then try reinstall CMake from source with --system-curl option:

$ ./bootstrap --system-curl 
$ make 
$ sudo make install
