This is a quick start guide for installing from binaries or compiling from source for MADlib^®.

Please note that a Greenplum database sandbox VM with MADlib pre-installed is also available to get started quickly, as an alternative to following the installation steps described on this page.

Quick Start With Binaries

Prerequisites

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

• PostgreSQL
• Greenplum database
• Pivotal HDB/Apache HAWQ (incubating)

Postgres platform notes:

• Ensure that you install Postgres with the Python extension specified.
• If environment variables are defined, this can save you some typing.

Installing MADlib

1. Download the MADlib binary
   • Postgres: Get either the OSX or Redhat/CentOS binary from the MADlib download page
   • Greenplum database and HDB/HAWQ : Download the .gppkg binary from Pivotal Network

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

• Greenplum Database:

  • on Redhat / CentOS run the following as gpadmin:

    gppkg -i <madlib_package>

• HDB/HAWQ:

  • on Redhat / CentOS run the following as gpadmin:

    gppkg -i <madlib_package>

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

1. • Ensure that psql, postgres, and pg_config are in your path

     which psql
     which postgres 
     which pg_config

   • 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.
     
     

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

   • 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

   • 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.

   • HDB/HAWQ:

     /usr/local/madlib/bin/madpack –p hawq 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

   Help output is also attached to this wiki page for your reference.

   
   

3. Test your installation

1. • Postgres:

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

   • 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.

   • HDB/HAWQ:

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

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

Compiling 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 HDB/HAWQ, Greenplum Database 4.2+ or PostgreSQL (64-bit) 9.2+ with plpython support enabled. Note: plpython may not be enabled in Postgres by default.

Installing MADlib

In the $MADLIB_ROOT directory (location of MADlib source) run the following commands:

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:

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

• To make sure that the installation is successful:

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

• For more information on the usage of madpack:
  

  $BUILD_ROOT/src/bin/madpack --help

Defining environment variables

The variables below 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
