Welcome to My Riak MapReduce Demo Rails App!

How to Get Started

• Clone this repo and install dependencies:

    git clone git://github.com/aitrus/lapreso.git
    cd lapreso
    export LAPRESO=`pwd`
    bundle install
  

• Install Riak Search. I suggest building a development release.

    # Pre-Requisites: erlang (possibly mercurial?)
    cd $LAPRESO/db
    curl -O http://downloads.basho.com/riak-search/riak-search-0.13/riak_search-0.13.0.tar.gz
    tar zxf riak_search-0.13.0.tar.gz
  
    rm riak_search-0.13.0.tar.gz
    mv riak_search-0.13.0 riak_search
    cd riak_search
  
    make all devrel
  

• Start Riak

    # Set your ulimits, if on a Mac (I suggest adding this to your .profile)
    ulimit -n 8192
  
    # Fire up the three dev nodes you built
    dev/dev1/bin/riaksearch start
    dev/dev2/bin/riaksearch start
    dev/dev3/bin/riaksearch start
  
    # Make em gossip
    dev/dev2/bin/riaksearch-admin join dev1@127.0.0.1
    dev/dev3/bin/riaksearch-admin join dev1@127.0.0.1
  

• Bring in a load balancer, to simulate something not so lob-sided (not necessary, but will be assumed)

    cd $LAPRESO/db
    curl -O http://siag.nu/pub/pen/pen-0.18.0.tar.gz   # Make this a brew package?
    tar zxf pen-0.18.0.tar.gz
  
    rm pen-0.18.0.tar.gz
    mv pen-0.18.0 pen
    cd pen
  
    ./configure && make
  
    cd $LAPRESO
    # Port 8098 is the default web port; we'll have the load balancer sit here and route it to our dev nodes
    db/pen/pen -x 500 -p tmp/pen-8098.pid localhost:8098 8098 localhost:8091 localhost:8092 localhost:8093
