2.11. Others

This section describes how to install Mroonga from source code. If there is no package no your environment, you need to build Mroonga from source code.

2.11.1. Dependencies

Mroonga needs some tools, libraries and MySQL for build. You can use MariaDB instead of MySQL. Tools

Here are required tools:

  • wget, curl or Web browser for downloading source archive

  • tar and gzip for extracting source archive

  • shell (many shells such as dash, bash and zsh will work)

  • C compiler and C++ compiler (gcc and g++ are supported but other compilers may work)

  • make (GNU make is supported but other make like BSD make will work)

  • pkg-config for detecting libraries

You must get them ready.

You can use CMake instead of shell but this document doesn’t describe about building with CMake.

Here are optional tools:

  • sudo for installing built Mroonga. Libraries

Here are required libraries:

Here are optional libraries:

  • MeCab: Japanese morphological analysis system


    If you want to use indexes of tokenizing of each morpheme for full text search, install MeCab before installing Groonga. MySQL

Mroonga needs not only installed MySQL but also MySQL source and build directory. You can’t use MySQL package. It doesn’t provide MySQL source and build directory. You need MySQL source and build directory!

If you use MariaDB instead of MySQL, you need MariaDB source.

Download the latest MySQL 5.6 source code, then build and install it.

Here we assume that you use mysql-5.6.21 and its source code is extracted in the following directory:


Then build in the following directory:


Here are command lines to build and install MySQL:

% cd /usr/local/build/mysql-5.6.21
% cmake /usr/local/src/mysql-5.6.21
% make
% sudo make install

And we assume that MySQL is installed in the following directory:


2.11.2. Build from source

Mroonga uses GNU build system. So the following is the simplest build steps:

% wget https://packages.groonga.org/source/mroonga/mroonga-6.12.tar.gz
% tar xvzf mroonga-6.12.tar.gz
% cd mroonga-6.12
% ./configure \
    --with-mysql-source=/usr/local/src/mysql-5.6.21 \
    --with-mysql-build=/usr/local/build/mysql-5.6.21 \
% make
% sudo make install
% /usr/local/mysql/bin/mysql -u root < /usr/local/share/mroonga/install.sql

You need to specify the following on configure:

  • The location of MySQL source code with --with-mysql-source.

  • The location of MySQL build directory with --with-mysql-build.

  • The path of mysql_config command with --with-mysql-config.

You can confirm Mroonga is installed successfully by SHOW ENGINES SQL. If you can find Mroonga row, Mroonga is installed successfully:

| Engine     | Support | Comment                                                    | Transactions | XA   | Savepoints |
| Mroonga    | YES     | Fulltext search, column base                               | NO           | NO   | NO         |
| MRG_MYISAM | YES     | Collection of identical MyISAM tables                      | NO           | NO   | NO         |
| CSV        | YES     | CSV storage engine                                         | NO           | NO   | NO         |
| MyISAM     | DEFAULT | Default engine as of MySQL 3.23 with great performance     | NO           | NO   | NO         |
| InnoDB     | YES     | Supports transactions, row-level locking, and foreign keys | YES          | YES  | YES        |
| MEMORY     | YES     | Hash based, stored in memory, useful for temporary tables  | NO           | NO   | NO         |

The following describes details about each step. configure

First, you need to run configure. Here are important configure parameters: --with-mysql-source=PATH

Specifies the location of MySQL source code.

This is required parameter:

% ./configure \
    --with-mysql-source=/usr/local/src/mysql-5.6.21 \
    --with-mysql-config=/usr/local/mysql/bin/mysql_config --with-mysql-build=PATH

Specifies the location where you build MySQL source code.

If you build MySQL in MySQL source code directory, you don’t need to specify this parameter. If you build MySQL in other directory, you need to specify this parameter.

Here is an example when you build MySQL in /usr/local/build/mysql-5.6.21:

% ./configure \
    --with-mysql-source=/usr/local/src/mysql-5.6.21 \
    --with-mysql-build=/usr/local/build/mysql-5.6.21 \
    --with-mysql-config=/usr/local/mysql/bin/mysql_config --with-mysql-config=PATH

Specifies the path of mysql_config command.

If mysql_config command can be found by PATH, you don’t need to specify this parameter. For example, if mysql_config command exists at /usr/bin/mysql_config, you don’t need to specify this parameter:

% ./configure \
    --with-mysql-source=/usr/local/src/mysql-5.6.21 --with-default-tokenizer=TOKENIZER

Specifies the default tokenizer for full text. You can custom it in my.cnf.

The default is TokenBigram.

Here is an example to use TokenMecab as the default tokenizer:

% ./configure \
    --with-mysql-source=/usr/local/src/mysql-5.6.21 \
    --with-mysql-config=/usr/local/mysql/bin/mysql_config \
    --with-default-tokenizer=TokenMecab --prefix=PATH

Specifies the install base directory. Mroonga related files are installed under ${PATH}/ directory except ha_mroonga.so. ha_mroonga.so is a MySQL plugin file. It is installed the plugin directory of MySQL.

The default is /usr/local. In this case, install.sql that is used for installing Mroonga is installed to /usr/local/share/mroonga/install.sql.

Here is an example that installs Mroonga into ~/local for an user use instead of system wide use:

% ./configure \
    --prefix=$HOME/local \
    --with-mysql-source=$HOME/local/src/mysql-5.6.21 \
    --with-mysql-config=$HOME/local/mysql/bin/mysql_config PKG_CONFIG_PATH=PATH

This is not a configure parameter but we describe it for users who doesn’t install Groonga into the standard location.

If Groonga is not installed in the standard location like /usr/lib, you need to specify its location by PKG_CONFIG_PATH. For example, if Groonga is installed with --prefix=$HOME/local, use the following command line:

./configure \
  PKG_CONFIG_PATH=$HOME/local/lib/pkgconfig \
  --with-mysql-source=/usr/local/src/mysql-5.6.21 \
  --with-mysql-config=/usr/local/mysql/bin/mysql_config make

configure is succeeded, you can build Mroonga by make:

% make

If you have multi cores CPU, you can make faster by using -j option. If you have 4 cores CPU, it’s good for using -j4 option:

% make -j4

If you get some errors by make, please report them to us: How to report a bug make install

Now, you can install built Mroonga!:

% sudo make install

If you have write permission for ${PREFIX} and the plugin directory of MySQL, you don’t need to use sudo. e.g. --prefix=$HOME/local case. In this case, use make install:

% make install mysql -u root < install.sql

You need to run some SQLs to register Mroonga to MySQL such as INSTALL PLUGIN and CREATE FUNCTION. They are written in ${PREFIX}/share/mroonga/install.sql.

Here is an example when you specify --prefix=$HOME/local to configure:

% mysql -u root < $HOME/local/share/mroonga/install.sql uninstall Mroonga

If you want to remove Mroonga, type below commands:

% mysql < ${PREFIX}/share/mroonga/uninstall.sql
% sudo make uninstall
