I am trying to install the ELK stack for the first time on AWS running Ubuntu 14.0.4 and using apt to install the latest stable packages and am running into some difficulties. Help would be greatly appreciated.

Elasticsearch seems to install just fine- if I curl [http://localhost:9200](http://localhost:9200) I get a nicely formatted bit of descriptive text. But starting Kibana (on the command line) yields:{"name":"Kibana","hostname":"ip-172-31-32-8","pid":3515,"level":60,"err":{"message":"unknown error","name":"Error","stack":"Error: unknown error\n at respond (/opt/kibana/src/node\_modules/elasticsearch/src/lib/transport.js:237:15)\n at checkRespForFailure (/opt/kibana/src/node\_modules/elasticsearch/src/lib/transport.js:203:7)\n at HttpConnector.

The kibana.yml file appears OK:

# Kibana is served by a back end server. This controls which port to use.

port: 5601

# The host to bind the server to.

host: "localhost"

# The Elasticsearch instance to use for all your queries.

elasticsearch\_url: "[http://localhost:9200](http://localhost:9200)"

# preserve\_elasticsearch\_host true will send the hostname specified in `elasticsearch`. If you set it to false,

# then the host you use to connect to _this_ Kibana instance will be sent.

elasticsearch\_preserve\_host: false

# Kibana uses an index in Elasticsearch to store saved searches, visualizations

# and dashboards. It will create a new index if it doesn't already exist.

kibana\_index: ".kibana"

# If your Elasticsearch is protected with basic auth, this is the user credentials

# used by the Kibana server to perform maintence on the kibana\_index at statup. Your Kibana

# users will still need to authenticate with Elasticsearch (which is proxied thorugh

# the Kibana server)

# kibana\_elasticsearch\_username: user

# kibana\_elasticsearch\_password: pass

# If your Elasticsearch requires client certificate and key

# kibana\_elasticsearch\_client\_crt: /path/to/your/client.crt

# kibana\_elasticsearch\_client\_key: /path/to/your/client.key

# If you need to provide a CA certificate for your Elasticsarech instance, put

# the path of the pem file here.

# ca: /path/to/your/CA.pem

# The default application to load.

default\_app\_id: "discover"

# Time in milliseconds to wait for elasticsearch to respond to pings, defaults to

# request\_timeout setting

# ping\_timeout: 1500

# Time in milliseconds to wait for responses from the back end or elasticsearch.

# This must be \> 0

request\_timeout: 300000
