I solved this issue. Rubygems had been installed using RVM which was not enabled for the root account. Thanks for your help!

Does anything need to be done once the install script has been executed? Thanks.

I've ran the script, then ran MONGOID_HOST=localhost MONGOID_PORT=27017 MONGOID_USERNAME=grayloguser MONGOID_PASSWORD=123 MONGOID_DATABASE=graylog2 /opt/graylog2/graylog2-web-interface/script/rails server -e production.

I can create an account, but then when I log in, I get the message "Could not connect to ElasticSearch", any ideas?

@SteveEdson, it's because the link to elasticsearch DEB is outdated. Use this one instead:

http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.20.5.deb
