ES service keeps crashing

Elastic Stack Elasticsearch
#1

Hi,

Just realised that after I start the service for Elastic it stops running after about 2 minutes. Checked the event logs and see some errors:

Any thoughts?

DHCP Logs to Logstash
#2

Would you able to share the logs from elasticsearch?

Elasticsearch logs for windows usually store at %ALLUSERSPROFILE%\Elastic\Elasticsearch\logs

#3

Think I found the problem, I have network.host: "0.0.0.0" in the elasticsearch.yml file, and when that is valid, the service crashes, if I # it out, it runs fine.
Would Logstash still be able to send logs to ES even if this field is not working? Logstash is installed on another server

#4

Sorry I'm not too sure on this.

#5

OK cool, what about how to resolve the issue of allowing other servers to access the ES server, as obviously, it defaults to localhost which won't work from another server

#6

Can you share your elasticsearch.yml ?

#7

Sure:

    bootstrap.memory_lock: false
    cluster.name: Elastic
    http.port: 9200
    node.data: true
    node.ingest: true
    node.master: true
    node.max_local_storage_nodes: 1
    node.name: SV-MSE-ELTC-001
    path.data: D:\Elastic\Elastic-7.9.2\Data
    path.logs: D:\Elastic\Elastic-7.9.2\Logs
    transport.tcp.port: 9300
    xpack.license.self_generated.type: basic
    xpack.security.enabled: false
    #network.host: "0.0.0.0"
#8

Sorry, what about the logs?

#9

If this is your reddit thread, then it looks like you had server.host in your elasticsearch.yml, which is not a valid setting.

If you have added network.host and it's not working, please provide the Elasticsearch logs.

Hi, Thanks, logs are below:

Literally just resolved this due to that error, thanks a lot. I added the following into the YML file:

discovery.seed_hosts: []
discovery.type: single-node
