Quick Start

Install Jubatus

We officially support Red Hat Enterprise Linux (RHEL) 6.2 or later (64-bit) and Ubuntu Server 14.04 LTS / 16.04 LTS / 18.04 LTS (64-bit). On supported systems, you can install all components of Jubatus using binary packages.

Other Linux distributions (including 32-bit) and Mac OS X are experimentally supported.

Red Hat Enterprise Linux 6.2 or later (64-bit)

Run the following command to register Jubatus Yum repository to the system.

// For RHEL 6
$ sudo rpm -Uvh http://download.jubat.us/yum/rhel/6/stable/x86_64/jubatus-release-6-2.el6.x86_64.rpm

// For RHEL 7
$ sudo rpm -Uvh http://download.jubat.us/yum/rhel/7/stable/x86_64/jubatus-release-7-2.el7.x86_64.rpm

Now install jubatus and jubatus-client package.

$ sudo yum install jubatus jubatus-client

To install a specific version of jubatus and jubatus-client, list the available versions.

$ yum list jubatus jubatus-client --showduplicates | sort -r

Install an available version, for example, 1.0.9.

$ sudo yum install jubatus-1.0.9-1.el7 jubatus-client-1.0.9-1.el7

On RHEL 6 systems, we use rhel-6-server-optional-rpms or jubatus-optional repository to install dependency package (oniguruma). If the installation command above fails with the missing oniguruma package error, try one of the following commands:

// For RHEL 6 systems that cannot find oniguruma package
$ sudo yum --enablerepo=rhel-6-server-optional-rpms install jubatus jubatus-client

// For RHEL 6 systems that cannot find oniguruma package (and rhel-6-server-optional-rpms is unavailable)
$ sudo yum --enablerepo=jubatus-optional install jubatus jubatus-client

Optionally you can install plug-ins. [1] [2] By installing plug-ins, Jubatus can perform feature extractions from Japanese natural language text and images.

$ sudo yum install jubatus-plugin-mecab jubatus-plugin-ux jubatus-plugin-image jubatus-plugin-python
[1]Prior to Jubatus 1.0, all plugins were bundled with jubatus package. In Jubatus 1.0 or later, you can selectively install plug-ins you need.
[2]A part of fuction in jubatus-plugin-image package (ORB algorithm) and jubatus-plugin-python package are not available in RHEL 6.

Ubuntu Server (64-bit)

Write the following line to /etc/apt/sources.list.d/jubatus.list to register Jubatus Apt repository to the system.

// For Ubuntu 12.04 (Precise) - Deprecated (unsupported)
deb http://download.jubat.us/apt/ubuntu/precise binary/

// For Ubuntu 14.04 (Trusty)
deb http://download.jubat.us/apt/ubuntu/trusty binary/

// For Ubuntu 16.04 (Xenial)
deb http://download.jubat.us/apt/ubuntu/xenial binary/

// For Ubuntu 18.04 (Bionic)
deb [trusted=yes] http://download.jubat.us/apt/ubuntu/bionic/binary /

Now install jubatus package.

$ sudo apt-get update
$ sudo apt-get install jubatus

To install a specific version of jubatus, list the available versions.

$ apt-cache madison jubatus
  jubatus |    1.1.0-1 | http://download.jubat.us/apt/ubuntu/xenial binary/ Packages
  jubatus |    1.0.9-1 | http://download.jubat.us/apt/ubuntu/xenial binary/ Packages

Install an available version, for example, 1.0.9.

$ sudo apt-get install jubatus=1.0.9-1

Currently our package is not GPG-signed. Bypass the warning by answering y to the prompt when asked:

Install these packages without verification [y/N]? y

Now Jubatus is installed in /opt/jubatus.

Each time before using Jubatus, you need to load the environment variable from profile script (you can add the line to ~/.profile).

$ source /opt/jubatus/profile

If you’re using csh or tcsh, use this instead:

$ source /opt/jubatus/profile.csh


You can use Docker image distributed at Dockerhub.

$ docker pull jubatus/jubatus
$ docker run --expose 9199 jubatus/jubatus jubaclassifier -f /opt/jubatus/share/jubatus/example/config/classifier/pa.json

Other Linux Distributions (including 32-bit)

Use jubatus-installer or see Building Jubatus from Source to build from source.

Mac OS X

If you’re using Homebrew, you can use tap repository for installation.

In other case, use jubatus-installer or see Building Jubatus from Source to build from source.

Install Jubatus Client Libraries

Jubatus client applications can be written in C++, Python, Ruby or Java. You need to setup the client library for each language to use Jubatus from client applications. Client libraries are distributed under MIT License.

If you’re going to try Basic Tutorial, just install Python client and go ahead.

Version of Jubatus and Jubatus clients may be different, as clients are not updated when there are no API changes to Jubatus.


The client is included in the Jubatus framework ($PREFIX/include/jubatus/client/*_client.hpp) and no additional setup is required.

If you don’t have compilers and/or development headers installed, you will need to setup them. For RHEL systems, type:

$ sudo yum groupinstall "Development tools" "Additional Development"

For Ubuntu systems, type:

$ sudo apt-get install build-essential


The client (requires Python 2.6, 2.7 or 3.x) is available in PyPI.

$ sudo pip install jubatus

If you only have Python 3.x, you may need to use pip3 instead of pip.

If you don’t have pip command, run the following command:

$ wget http://peak.telecommunity.com/dist/ez_setup.py
$ sudo python ez_setup.py
$ sudo easy_install pip

On Ubuntu, you can also use python-pip package to install pip.


The client (requires Ruby 1.9 or later) is available in RubyGems.

$ sudo gem install jubatus


The client is available in our Maven repository. Please add these lines to pom.xml of your project.

    <name>Jubatus Repository for Maven</name>
