Install Milvus from Source Code

• Build from source
• Compile Milvus on Docker

Build from source

Requirements

• Ubuntu 18.04 or higher

  If your operating system is not Ubuntu 18.04 or higher, we recommend you to pull a docker image of Ubuntu 18.04 as your compilation environment.

• CMake 3.12 or higher

For GPU-enabled 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-only version. To build GPU version, add -g option

$ ./build.sh -g

If you want to know the complete build options, run

$./build.sh -h

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

Compile Milvus on Docker

With this dockerfile, you should be able to compile Milvus on any Linux platform that run Docker. To build a GPU supported Milvus, you neeed to install NVIDIA Docker first.

Step 1 Pull Milvus Docker images

Pull CPU-only image:

$ Docker pull milvusdb/milvus-cpu-build-env:v0.6.0-ubuntu18.04

Pull GPU-enabled image:

$ Docker pull milvusdb/milvus-gpu-build-env:v0.6.0-ubuntu18.04

Step 2 Start the Docker container

Start a CPU-only container:

$ Docker run -it -p 19530:19530 -d milvusdb/milvus-cpu-build-env:v0.6.0-ubuntu18.04

Start a GPU container:

$ Docker run — runtime=nvidia -it -p 19530:19530 -d milvusdb/milvus-gpu-build-env:v0.6.0-ubuntu18.04

To enter the container:

$ Docker exec -it [container_id] bash

Step 3 Download Milvus source code

Download Milvus source code:

$ cd /home
$ wget https://github.com/milvus-io/milvus/archive/0.6.0.zip

Unzip the source package:

$ Apt-get update
$ Apt-get install unzip
$ unzip ./0.6.0.zip

The source code is extracted into a folder called milvus-0.6.0. To enter its core directory:

$ cd ./milvus-0.6.0/core

Step 4 Compile Milvus in the container

If you are using a CPU-only image, compile it like this:

$ ./build.sh -t Release

If you are using a GPU-enabled image, you need to add a -g parameter:

$ ./build.sh -g -t Release

Then start Milvus server：

$ ./start_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
