How do I setup SearchKick/ElasticSearch on the NEW

I am following the McKenzie Childs tutorial on making a "Movie Review" app on Ruby on Rails and he is using the searchkick gem. I am doing everything through the new Nitrous platform and everything is confusing.

I was running this command to:

rake searchkick:reindex CLASS=Movie

and got the following error in the shell:

rake aborted!

I have a feeling that its something in regards to connecting a port or starting some server. This is the first month of the new Nitrous Web IDE.

Did the tutorial yesterday and ran into the same issue(was using cloud9 IDE). I noticed I was getting that error because elastic search wasn't running. I uninstalled it using the command

sudo apt-get --purge autoremove elasticsearch

then made a fresh install.

wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.7.0.deb
sudo dpkg -i elasticsearch-1.7.0.deb

#enable on bootup
sudo update-rc.d elasticsearch defaults 95 10

### Start ElasticSearch 
sudo /etc/init.d/elasticsearch start

### Make sure service is running
curl http://localhost:9200

### Should return something like this:
# {
#  "status" : 200,
#  "name" : "Storm",
#  "version" : {
#    "number" : "1.3.1",
#    "build_hash" : "2de6dc5268c32fb49b205233c138d93aaf772015",
#    "build_timestamp" : "2014-07-28T14:45:15Z",
#    "build_snapshot" : false,
#    "lucene_version" : "4.9"
#  },
#  "tagline" : "You Know, for Search"
#}

Searchkick worked after this. You should have java installed though before installing elastic search. Hope this helps you
