 That DO article left out some steps about allowing Firewall rules for some of the ports, I think. I've bee na few days since I've looked at it... I have noticed that I need to set the Kiban4 and logstash processes to restart once a day or the whole thing stops.

 /etc/yum.repos.d/elasticsearch.repo**** [elasticsearch-1.4] 
 name=Elasticsearch repository for 1.4.x packages
 baseurl=http://packages.elasticsearch.org/elasticsearch/1.4/centos
 gpgcheck=1
 gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch

 I really like the Digital Ocean tutorial series they did a while ago, like installing MediaWiki. Creating something which you can use at home also helps make projects like these a bit more personal - and thus interesting.
