A quick start guide for installing from binaries or compiling from source for MADlib®.

Quick Start With Binaries

Prerequisites

Install and configure your database of choice. MADlib currently supports the following platforms:

  • PostgreSQL
  • Greenplum database
  • Apache HAWQ (incubating)

This guide describes the installation steps for Postgres and Greenplum.  (HAWQ installation steps will be added at a later date.)

Postgres platform notes:

Installing MADlib

  1. Download the MADlib binary
  2. Install the package at the OS level.
    • Postgres:
      • on OSX double click the installer package

      • on Redhat / CentOS run the following as root

        yum install <madlib_package> --nogpgcheck
    • Pivotal Greenplum Database:

      • on Redhat / CentOS run the following as gpadmin

        gppkg install <madlib_package>

Ensure that the environment is setup for your database deployment and that the database is up and running.

  • Ensure that psql, postgres, and pgconfig are in your path

    which psql which postgres which pgconfig

  • Ensure that the database is started and running

    psql –c 'select version()'

The above may need user/port/password setting depending on how the database has been configured.

  1. Run the MADlib deployment utility to install MADlib into each database that you want to use it in:

    • Postgres: /usr/local/madlib/bin/madpack -s madlib –p postgres install

      if environment variables are defined. Otherwise use a fully defined connection string: /usr/local/madlib/bin/madpack -s madlib -p postgres -c [user[/password]@][host][:port][/database] install

    • Pivotal Greenplum Database: /usr/local/madlib/bin/madpack –p greenplum install

    The above may need user/port/password setting depending on how the database has been configured.

     

    For more information on madpack:

    /usr/local/madlib/bin/madpack --help

  2. Test your installation to validate proper installation

    • Postgres:

      /usr/local/madlib/bin/madpack -s madlib –p postgres install-check

    • Pivotal Greenplum Database:

      /usr/local/madlib/bin/madpack –p greenplum install-check

      The above may need user/port/password setting depending on how the database has been configured.

## Compile From Source

Prerequisites

Requirements for installing MADlib:

  • gcc (For OSX, Clang will work for compiling the source, but not for documentation.)
  • An installed version of Pivotal HAWQ, Pivotal Greenplum Database 4.2+ or PostgreSQL (64-bit) 9.2+ with plpython support enabled. Note: plpython may not be enabled in PostgreSQL by default.

Installing MADlib

In the $MADLIB_ROOT (location of MADlib source) run the following commands bash mkdir build cd build cmake .. make

Above, we built the executables in the build folder. This can, however, be any user-named folder (henceforth called $BUILD_ROOT).

Deploying MADlib

Deploy MADlib into the database with MADlib package manager madpack located under $BUILD_ROOT/src/bin.

- to install, run `$BUILD_ROOT/src/bin/madpack -p postgres -c [user[/password]@][host][:port][/database]  install`

    - to make sure that the installation is successful, run `$BUILD_ROOT/src/bin/madpack -p postgres -c [user[/password]@][host][:port][/database] install-check`

    - for more information on the usage of `madpack`, run `$BUILD_ROOT/src/bin/madpack --help`

Defining environment variables

The below variables will be automatically used by the madpack installer if no connection string is provided.

1. User: PGUSER or USER (defaults to OS username) 2. Password: PGPASSWORD (defaults to empty) 3. Host: PGHOST (defaults to 'localhost') 4. Database: PGDATABASE (defaults to OS username) 5. Port: PGPORT (defaults to 5432)

An example of deploying MADlib using the environment variables:

export PGPORT=5430
    export PGHOST=127.0.0.1
    export PGDATABASE=madlibtest
    $BUILD_ROOT/src/bin/madpack -p postgres install
