Compilation

Step 1: install necessery tools

Install MySQL

centos7 : 
    yum install gfortran qt4 flex bison mysql-devel
    
ubuntu16.04 : 
    sudo apt-get install gfortran qt4-qmake flex bison libmysqlclient-dev

If libmysqlclient_r.so does not exist after installing MySQL Development Files, you need to create a symbolic link:

sudo ln -s /path/to/libmysqlclient.so /path/to/libmysqlclient_r.so

Step 2: build(output to cmake_build folder)

cmake_build/src/milvus_server is the server

cmake_build/src/libmilvus_engine.a is the static library

cd [sourcecode path]/cpp
./build.sh -t Debug
./build.sh -t Release
./build.sh -l -t Release # Build license version(only available for Release)

If you encounter the following error when building: protocol https not supported or disabled in libcurl

1. Install libcurl4-openssl-dev

2. Install cmake 3.14:

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

To build unittest:

./build.sh -u
or
./build.sh --unittest

To run code coverage

apt-get install lcov
./build.sh -u -c

Launch server

Set config in cpp/conf/server_config.yaml

Add milvus/bin/lib to LD_LIBRARY_PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/milvus/bin/lib

Then launch server with config: cd [build output path] start_server.sh stop_server.sh

Launch test_client(only for debug)

If you want to test remote api, you can build test_client. test_client use same config file with server:

cd [build output path]/test_client
test_client -c [sourcecode path]/cpp/conf/server_config.yaml

License Generate

Use get_sys_info to get system info file.

./get_sys_info                  # system.info will be generated

Use license_generator to generate license file.

./license_generator -s system.info -l system.license -b 2019-05-15 -e 2019-08-14                 

Copy the license file to path assigned by license_path in server config file.
