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@SteveEdson, it's because the link to elasticsearch DEB is outdated.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
