Install Nebula Graph by compiling the source code

Installing Nebula Graph from the source code allows you to customize the compiling and installation settings and test the latest features.

Prerequisites

  • You can access the Internet from the host you plan to install Nebula Graph.
  • The console is not complied or packaged with Nebula Graph server binaries. You can install nebula-console by yourself.

How to install

  1. Use Git to clone the source code of Nebula Graph to your host.

    • To install the latest developing version, run the following command to download the source code from the master branch.
      $ git clone https://github.com/vesoft-inc/nebula-graph.git
    • To install a specific release version, use the --branch option to specify the correct branch. For example, to install 2.0.0, run the following command.
      $ git clone --branch v2.0.0 https://github.com/vesoft-inc/nebula-graph.git

  2. Make the nebula-graph directory the current working directory.

    $ cd nebula-graph

  3. Create a build directory and make it the current working directory.

    $ mkdir build && cd build

  4. Generate the Makefile with CMake.

    Note

    • The installation path is /usr/local/nebula by default. To customize it, add the -DCMAKE_INSTALL_PREFIX=/your/install/path/ CMake variable in the following command.
    • If you are installing the latest developing version and has cloned the master branch in step 1, run the following command.
      $ cmake -DENABLE_BUILD_STORAGE=on -DENABLE_TESTING=OFF -DCMAKE_BUILD_TYPE=Release ..
    • If you are installing a specific release version and has cloned the corresponding branch in step 1, use the -DNEBULA_COMMON_REPO_TAG and -DNEBULA_STORAGE_REPO_TAG options to specify the correct branches of the nebula-common and nebula-storage repositories. For example, to install release version 2.0.0, run the following command.
      $ cmake -DENABLE_BUILD_STORAGE=on -DENABLE_TESTING=OFF -DCMAKE_BUILD_TYPE=Release \
-DNEBULA_COMMON_REPO_TAG=v2.0.0 -DNEBULA_STORAGE_REPO_TAG=v2.0.0 ..

  5. Compile Nebula Graph.

    To speed up the compiling, use the -j option to set a concurrent number N. It should be min(MEM/2, CPU), where MEM is the memory size in GB, and CPU is the core number.

    $ make -j{N} # E.g., make -j4

    This step will take about 20 minutes on a VM with four cores of Intel(R) Xeon(R) Platinum 8260M CPU @ 2.30GHz.

  6. Install Nebula Graph.

    $ sudo make install-all

  7. [Optional] Update the source code of the master branch. (It changes frequently.)

    1. In the nebula-graph/ directory, you can use git pull upstream master to update the source code.

    2. In nebula-graph/modules/common/ and nebula-graph/modules/storage/, run git pull upstream master separately.

    3. In nebula-graph/build/, make and make install[-all] again.

CMake variables

Usage of CMake variables:

$ cmake -D<variable>=<value> ...

The following CMake variables can be used at the configure (cmake) stage to adjust the compiling settings.

ENABLE_BUILD_STORAGE

Starting from the 2.0 pre-release, Nebula Graph uses two separated github repositories of compute and storage. The ENABLE_BUILD_STORAGE variable is set to OFF by default so that the storage service is not installed together with the graph service.

If you are deploying Nebula Graph on a single host for testing, you can set ENABLE_BUILD_STORAGE to ON to download and install the storage service automatically.

CMAKE_INSTALL_PREFIX

CMAKE_INSTALL_PREFIX specifies the path where the service modules, scripts, configuration files are installed. The default path is /usr/local/nebula.

ENABLE_WERROR

ENABLE_WERROR is ON by default and it makes all warnings into errors. You can set it to OFF if needed.

ENABLE_TESTING

ENABLE_TESTING is ON by default and unit tests are built with the Nebula Graph services. If you just need the service modules, set it to OFF.

ENABLE_ASAN

ENABLE_ASAN is OFF by default and the building of ASan (AddressSanitizer), a memory error detector, is disabled. To enable it, set ENABLE_ASAN to ON. This variable is intended for Nebula Graph developers.

CMAKE_BUILD_TYPE

Nebula Graph supports the following building types:

  • Debug, the default value of CMAKE_BUILD_TYPE, indicates building Nebula Graph with the debug info but not the optimization options.
  • Release, indicates building Nebula Graph with the optimization options but not the debug info.
  • RelWithDebInfo, indicates building Nebula Graph with the optimization options and the debug info.
  • MinSizeRel, indicates building Nebula Graph with the optimization options for controlling the code size but not the debug info.

CMAKE_C_COMPILER/CMAKE_CXX_COMPILER

Usually, CMake locates and uses a C/C++ compiler installed in the host automatically. But if your compiler is not installed at the standard path, or if you want to use a different one, run the command as follows to specify the installation path of the target compiler:

$ cmake -DCMAKE_C_COMPILER=<path_to_gcc/bin/gcc> -DCMAKE_CXX_COMPILER=<path_to_gcc/bin/g++> ..
$ cmake -DCMAKE_C_COMPILER=<path_to_clang/bin/clang> -DCMAKE_CXX_COMPILER=<path_to_clang/bin/clang++> ..

ENABLE_CCACHE

ENABLE_CCACHE is ON by default and ccache is used to speed up the compiling of Nebula Graph.

To disable ccache, set ENABLE_CCACHE to OFF. On some platforms, the ccache installation hooks up or precedes the compiler. In such a case, you have to set an environment variable export CCACHE_DISABLE=true or add a line disable=true in ~/.ccache/ccache.conf as well.

For more information, see the ccache official documentation.

NEBULA_THIRDPARTY_ROOT

NEBULA_THIRDPARTY_ROOT specifies the path where the third party software is installed. By default it is /opt/vesoft/third-party.
