CentOS
======

This section describes how to install Groonga related RPM packages on
CentOS. You can install them by ``yum``.

We distribute both 32-bit and 64-bit packages but we strongly
recommend a 64-bit package for server. You should use a 32-bit package
just only for tests or development. You will encounter an out of
memory error with a 32-bit package even if you just process medium
size data.

CentOS 7
--------

Install::

  % sudo yum install -y https://packages.groonga.org/centos/7/groonga-release-latest.noarch.rpm
  % sudo yum install -y --enablerepo=epel groonga

If you want to use `MeCab <https://taku910.github.io/mecab/>`_ as a
tokenizer, install groonga-tokenizer-mecab package.

There is a package that provides `Munin
<http://munin-monitoring.org/>`_ plugins. If you want to monitor
Groonga status by Munin, install groonga-munin-plugins package.

There is a package that provides MySQL compatible normalizer as
