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 5
--------

Install::

  % sudo rpm -ivh http://packages.groonga.org/centos/groonga-release-1.1.0-0.noarch.rpm

tokenizer, install groonga-tokenizer-mecab package.

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