Install elasticsearch on OpenShift

Question

I installed a pre build Elasticsearch 1.0.0 version by reading this tutorial. If I start elasticsearch I got the following error message, Should I try an older version of ES or how to fix this issue?

It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Answer 1

you try to assign ES to port 8080, which already is taken. the culprit in the config from there is http.port: ${OPENSHIFT_DIY_PORT}. just leave both port configs out of the config or assign the envvar some other port. the default ports for ES are 9200 for http and 9300.

Answer 2

You first have to stop the running demo application, which is already bound to 8080. This can be done with this command:

ctl_app stop

After running this command you will be able to start elasticsearch on the port 8080. However this is not recommended for production environments.

Answer 3

I would recommend installing ElasticSearch with this cartridge: https://github.com/ncdc/openshift-elasticsearch-cartridge

It will save you the headaches of manual custom configurations.
