Kibana has problems connecting to Elasticsearch

Dusan_Dordevic · March 24, 2014, 1:48pm

Hi,

I downloaded elasticsearch-1.0.1.noarch.rpm,
logstash-1.4.0-1_c82dc09.noarch.rpm and kibana-3.0.0.tar.gz from
http://www.elasticsearch.org/overview/elkdownloads/ and installed them on
RHEL 6 with Apache and self signed http cert.

I replaced default Kibana dashboard with logstash dashboard that comes with
Kibana (cp logstash.json default.json in kibana/app/dashboards)

When I connect from another machine's browser to
https://10.142.4.104/kibana I get following error message:

Could not reach http://10.142.4.104:9200/_nodes. If you are using a proxy,
ensure it is configured correctly

However from that same machine curl http://10.142.4.104:9200/_nodes works
without any problems, and one with pretty output also:

curl 10.142.4.104:9200/_nodes/process?pretty
{
"cluster_name" : "aerlingus",
"nodes" : {
"avemXrb9SB6lxgxgL54ecA" : {
"name" : "central-log-server",
"transport_address" : "inet[/10.142.4.104:9300]",
"host" : "central-log-server",
"ip" : "10.142.4.104",
"version" : "1.0.1",
"build" : "5c03844",
"http_address" : "inet[/10.142.4.104:9200]",
"attributes" : {
"master" : "true"
},
"process" : {
"refresh_interval" : 1000,
"id" : 28121,
"max_file_descriptors" : 65535,
"mlockall" : false
}
}
}
}

Any idea what might be the problem ?

Thanks,
Dusan

I'm curious, I noticed you have https, and then http in your above
examples. Is that a typo (the https) or is that intentional?

Intentional. HTTPS goes to web server, http requests goes to
elasticsearch, port 9200

Another q, did you open up the config.js file in the Kibana install, and
change the elasticsearch url to explicity point to the "http" address of
your ES instance?

Yes, I assume that is how Kibana knows where is Elasticsearch, config file says:

elasticsearch: "http://10.142.4.104:9200",

Is it likely that you have a cross domain issue here?

Maybe it is a cross domain, but I do not have idea what might be wrong...

Have you figured out a solution ?
I am getting this all of a sudden !
I can access it ok via ip address but not via kibana via nginx rev proxy ..

You can find an example reverse proxy config for nginx here -
