To set up PostgreSQL + MADLib MADlib with Anaconda Python on OSX: 

...

• PYTHON=/Users/janedoe/anaconda/bin/

...

• python 

•  Install Postgres with the Python extension specified (i.e., --with-python), as described here in the PostgreSQL documentation. Note that previously you could install postgres with python support using brew by running 'brew install postgresql --with-python' but passing the '--with-python' flag is not supported anymore.
  

•  Set up database and roles

•  Install the .dmg of latest madlib downloaded from MADlib website https://madlib.

1. Download the MADlib binary
   • Postgres: Get either the OSX or Redhat/CentOS binary from the For Postgres: OS X and Linux binaries can be found on the MADlib download page
   • For Greenplum: Linux .gppkg binaries can be found on Pivotal Network in the "Greenplum Advanced Analytics Group"
     • NOTE: the above .gppkg binaries work for both open and closed source Greenplum and can be downloaded by anybody (after creating a Pivotal Network account)
     Greenplum database : Download the .gppkg binary from Pivotal Network
2. Install the package

...

1. .
   
   1. Postgres:
      • on OSX double click the installer package

      • on Redhat / CentOS run the following as root:

        Code Block
        yum install <madlib_package> --nogpgcheck

        or

        Code Block
        language bash
        rpm -i <madlib_package>

        
        

   2. Greenplum

...

1. 1. :

      • on Redhat / CentOS run the following as gpadmin:

        Code Block
        language bash
        gppkg -i <madlib_package>

...

1. 1. • 
        

   2. NOTE: if you are using an rpm package on a CentOS 5 system, please add --no-deps flag to the command.
2. Ensure that the environment is setup for your database deployment and that the database is up and running.

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

     Code Block
     language bash
     which psql which postgres which pg_config

     
     

   • Ensure that the database is started and running

     Code Block
     language bash
     psql -c 'select version()'

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

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

   • Postgres:

     Code Block
     language bash
     /usr/local/madlib/bin/madpack -s madlib –p postgres install

     if environment variables are defined. Otherwise use a fully defined connection string:

     Code Block
     language bash
     /usr/local/madlib/bin/madpack -s madlib -p postgres -c [user[/password]@][host][:port][/database] install

     
     

   • Greenplum Database:

     Code Block
     language bash
     /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:

   Code Block
   language bash
   /usr/local/madlib/bin/madpack --help

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

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

4. After installation gpadmin should grant all privileges on schema madlib to users who will be accessing MADlib functions. Otherwise, users will get "ERROR: permission denied for schema MADlib."  Also, install checks (see next step below) will fail if CREATE TEMP TABLE privileges are not granted on the schema where MADlib is installed. See the PostgreSQL docs for information on schemas and privileges.

5. Test your installation

1. • Postgres:

     Code Block
     language bash
     /usr/local/madlib/bin/madpack -s madlib –p postgres install-check

     
     

   • Greenplum Database:

     Code Block
     language bash
     /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. 
     
     Please note that if the optimizer_control GUC is set to off in Greenplum, the following install checks will fail, and these MADlib functions will not work:  decision tree, random forest, LDA , k-Means, PMML export for decision tree, PMML export for random forest.  This will be fixed in a future release (MADLIB-1109).  The parameter optimizer_control controls whether the server configuration parameter optimizer can be changed. The parameter optimizer controls whether the GPORCA optimizer is enabled when running SQL queries.

Compiling From Source

Prerequisites

Prerequisites

Requirements for installing MADlib:

• gcc and g++ (
  • For
  OSX
  • OS X, Clang will work for compiling the source, but not for
  documentation.)
  • NOTE: On Ubuntu 16.04, you will need to use GCC 4 and not the default compiler (GCC 5) to run MADlib. Refer to MADLIB-1068 for details. The outstanding GCC 5 issue is being tracked under MADLIB-1145.
    
• An installed version of Greenplum Database 4.2+ or PostgreSQL (64-bit) 9.2+ with plpython support enabled.  
  • NOTE: plpython may not be enabled in Postgres by default. 
• MADlib works with Python 2.6 and 2.7.  Currently, Python 3.x is not supported.
• • the documentation. To compile on newer versions of XCode we need to enable the CXX11 flag. Setting -DCXX11=1 during cmake, will auto-download Boost 1.75.0 if Boost > 1.65.0 is not found on the system.
    Note: Setting -DCXX11=1 will enable C++11, which is not fully supported, i.e, MADlib compiles but some install-check/dev-check tests may fail.
• python 2.6 or 2.7
  • python 3.x is not currently supported by MADlib.
• cmake
  • NOTE:
  cmake (
  • the latest version of cmake might cause issues. Please try cmake 3.5.2 in case you get an error or a segmentation fault.
  )
  • NOTE: On Centos 6 (possibly other Linux variants), we have seen occasions where cmake will have issues running (seg fault) if the greenplum_path.sh file has been sourced prior to the cmake execution. If you encounter issues, you can use ldd on the cmake executable to confirm dynamic libraries are picked up from the Greenplum installation directories. If this is the case, start a new shell in which the greenplum_path.sh file is not sourced in your current running shell session. You can reference MADLIB-1093 for additional details.

Installing MADlib

• An installed version of Greenplum Database 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 the MADlib source) run the In the $MADLIB_ROOT directory (location of MADlib source) run the following commands:

mkdir build 
cd build 
cmake .. 
make -j8 # if this causes issues, switch back to a plan `make`

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

...

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

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

• Postgres:

  Code Block
  language bash
  $BUILD_ROOT/src/bin/madpack -s madlib –p postgres install

  if environment variables are defined. Otherwise use a fully defined connection stringTo install:

  Code Block
  language bash
  $BUILD_ROOT/src/bin/madpack -s madlib -p postgres -c [user[/password]@][host][:port][/database] install

  
  

• Greenplum Database:

  Code Block
  language bash
  $BUILD_ROOT/src/bin/madpack –p greenplum install

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

• To installTo make sure that the installation is successful:
