Hi!

Elasticsearch is a flexible and powerful free / libre / open source, distributed, real-time search and analytics engine. It is super fast, RESTful, based on Apache Lucene and has a very high activity level: https://www.ohloh.net/p/elasticsearch

It is part of "The Elasticsearch ELK Stack". The two other apps of the stack are:
* Logstash helps you take logs and other time based event data from any system and store it in a single place for additional transformation and processing.
* Kibana is Elasticsearch’s data visualization engine, allowing you to natively interact with all your data in Elasticsearch via custom dashboards.

See also: http://solr-vs-elasticsearch.com/


Does anyone have experience / interest with it? I would like to explore running Elasticsearch on ClearOS, and handling the security aspects:
* https://github.com/elasticsearch/elasticsearch/issues/664
* https://github.com/sonian/elasticsearch-jetty

Elasticsearch is part of Tiki suite:
* http://www.clearfoundation.com/Community/Groups/141/Viewgroup.html
* https://suite.tiki.org/Tiki+Suite

These are the types of use cases we are looking to cover:
https://tiki.org/Use+Cases+for+NLP+and+IR+in+Tiki

I would like to extend this to data outside Tiki, notably the files in the ClearOS-Samba Flexshares and emails in Zarafa.

Best regards,

M ;-)

    Great addition To ClearOS Marc, thanks!

    I just installed ElasticSearch following
    yum install app-elasticsearch
    I see now the ClearOs panel showing ElasticSearch 5.6.8.

    I see that last ElasticSearch version is 6.4.1 (https://www.elastic.co/downloads/elasticsearch).

    That would be great to be able to have a fresher version. :)

    An Elasticsearch app is currently in testing. It will be added to the Marketplace later, but you can install now with yum install app-elasticsearch

    All the details here:

    According to this page:
    http://www.clearfoundation.com/docs/web_site/clearfoundation_web_site_guide#documentation_wiki
    You should be able to edit.

    Can you try to use your regular login on wiki pages?

    Thanks!

    Hi Marc,

    I've tested with a virtual machine with ClearOS Community 6.5.

    - it's rpm --import (2x dash)
    - maybe it's better to download the key with wget:


    wget http://packages.elasticsearch.org/GPG-KEY-elasticsearch


    and do


    rpm --import GPG-KEY-elasticsearch.


    - you also have to start elasticsearch:


    service elasticsearch start


    then you can do:

    curl localhost:9300


    output:

    [root@vmtest /]# curl localhost:9200
    {
    "status" : 200,
    "name" : "Grenade",
    "version" : {
    "number" : "1.0.3",
    "build_hash" : "61bfb72d845a59a58cd9910e47515665f6478a5c",
    "build_timestamp" : "2014-04-16T14:43:11Z",
    "build_snapshot" : false,
    "lucene_version" : "4.6"
    },
    "tagline" : "You Know, for Search"
    }


    not sure what to do next but i haven't read any manual....

    Java was already installed on my vm. I'm pretty sure i didn't installed it manually.

    Hi!

    I just made a page on how to install Elasticsearch on ClearOS:
    http://www.clearfoundation.com/docs/howtos/elasticsearch

    Can someone take 10 minutes to validate?

    Thanks!

    So ClearOS 6.6 Beta now has WordPress & Tiki :-)

    And beyond web applications, Logstash is used for Apache logs, Syslog, etc.

    Something to investigate for 6.7 or 6.8...

    Thanks!

    Hi Marc,

    ClearOS doesn't have any apps that can be used for creating content -- those apps are coming with Tiki, Wordpress, etc., but have not yet arrived. I'm ready to dogfood/bootstrap getting ElasticSearch running on ClearOS, but the aforementioned apps need to be delivered first :-)
