Why cant I connect to elasticsearch via a loopback?

Trying to run curator locally on an ES instance.

I have this config:

---
# Remember, leave a key empty if there is no value.  None will be a string,
# not a Python "NoneType"
client:
  hosts:
    - 127.0.0.1
  port: 9200
  url_prefix:
  use_ssl: False
  certificate:
  client_cert:
  client_key:
  ssl_no_validate: False
  http_auth:
  timeout: 30
  master_only: False

logging:
  loglevel: INFO
  logfile:
  logformat: default
  blacklist: ['elasticsearch', 'urllib3']

127.0.0.1 won't connect, but putting in the server's actual ip will. Do I have to explicitly allow connections to the loopback for ES?

Solution

  • Not sure which version of Elasticsearch you are using, but, in short, yes, you need to specify that you want to listen on the loopback.

    you'll need to set that on the network.host property in your elasticsearch.yml (it accepts an array of values).

    network.host : [ "your_server_dns_name", "127.0.0.1" ]

    by example.
