Installing Kibana under Passenger for Apache in Ubuntu 12.04

Kibana is a very nice frontend for Logstash gathered logs sent to ElasticSearch. It's likely to be merged with Logstash at some point, but at the moment it's installed on its own.

Kibana now conforms to Rack conventions, which makes it easy to deploy using Passenger. At the time of writing the downloadable zip file (v0.2.0) does not, so you need to download it from Github.

Install dependencies:

apt-get install libapache2-mod-passenger apache2 ruby ruby1.8-dev libopenssl-ruby rubygems git -y

Get Kibana and rubygems needed

cd /var/www
git clone --branch=kibana-ruby https://github.com/rashidkpc/Kibana.git --depth=1 kibana
cd kibana
gem install bundle
bundle install

Set up a virtualhost for Apache:

<VirtualHost *:80>
    ServerName kibana
    DocumentRoot /var/www/kibana/public
    <Directory /var/www/kibana/public>
        Allow from all
        Options -MultiViews
    </Directory>
</VirtualHost>

Then just restart apache, and browse to your newly installed Kibana!
Notes:
Elasticsearch server is set to localhost:9200 by default. If this is not the case, configuration is found in /var/www/KibanaConfig.rb
