I am using elastic search in my ubuntu16.04 server. When i am trying to access elasticsearch from browser by using url ip:port/_cat/indices?v. I am getting site can't be reached. After that i am change the network.host value to network.host: 0.0.0.0. After change the network.host ip the search engine not started. How can i access the elasticsearch in my browser.I changed the port also.

Thank you..

  • Check the elastic startup logs to know on what port the elastic is running. Try connecting from the same machine browser first. If that works, then a problem of not able to connect from other machine is related to route/publicip configuration. – Shailesh Pratapwar Feb 14 '19 at 05:37
  • check port is open or not e.g 9200 for es or 5601 for kibana? – A l w a y s S u n n y Feb 14 '19 at 06:46

  • I am getting this errors when running es [1]: max file descriptors [10240] for elasticsearch process is too low, increase to at least [65536] [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] – SATHEESH P Feb 14 '19 at 07:09

There can be many reasons for ES not being reachable. I would start with the obvious and make sure that:

  1. ES is listening on the port: on the ES instance when you run 'curl ip:port' you should get an answer. if not the service didn't start well.

  2. make sure there are no firewall rules/security groups that prevent access from remote network.

  3. make sure network.publish_host is configure correctly: https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html#advanced-network-settings
