Elasticsearch service won't run on new installation

System - Dell T310 32 GB RAM Ubuntu Server 18.04 with Xubuntu GUI added. Installation of GUI for Elasticsearch hasn't been done because the service won't stay running.

Tell me what else you need to troubleshoot my issue. I've been beating my heat against Google for about 6 hours now. Thank you.

======================== Elasticsearch Configuration =========================

NOTE: Elasticsearch comes with reasonable defaults for most settings.

Before you set out to tweak and tune the configuration, make sure you

understand what are you trying to accomplish and the consequences.

The primary way of configuring a node is via this file. This template lists

the most important settings you may want to configure for a production cluster.

Please consult the documentation for further information on configuration options:

https://www.elastic.co/guide/en/elasticsearch/reference/index.html

---------------------------------- Cluster -----------------------------------

Use a descriptive name for your cluster:

#cluster.name: my-application

------------------------------------ Node ------------------------------------

Use a descriptive name for the node:

#node.name: node-1

Add custom attributes to the node:

#node.attr.rack: r1

----------------------------------- Paths ------------------------------------

Path to directory where to store the data (separate multiple locations by comma):

path.data: /var/lib/elasticsearch

Path to log files:

path.logs: /var/log/elasticsearch

----------------------------------- Memory -----------------------------------

Lock the memory on startup:

#bootstrap.memory_lock: true

Make sure that the heap size is set to about half the memory available

on the system and that the owner of the process is allowed to use this

limit.

Elasticsearch performs poorly when the system is swapping the memory.

---------------------------------- Network -----------------------------------

Set the bind address to a specific IP (IPv4 or IPv6):

network.host: 192.168.1.252

Set a custom port for HTTP:

http.port: 9200

For more information, consult the network module documentation.

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when new node is started:

The default list of hosts is ["127.0.0.1", "[::1]"]

#discovery.zen.ping.unicast.hosts: ["host1", "host2"]

Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):

#discovery.zen.minimum_master_nodes:

For more information, consult the zen discovery module documentation.

---------------------------------- Gateway -----------------------------------

Block initial recovery after a full cluster restart until N nodes are started:

#gateway.recover_after_nodes: 3

For more information, consult the gateway module documentation.

---------------------------------- Various -----------------------------------

Require explicit names when deleting indices:

#action.destructive_requires_name: true

this forum supports markdown for formatting snippets. Please use this.

Also, it would be useful to include the full exception. Judging from the snippet something around the network.host setting is off - this may be indentation but is hard to tell without more logfiles.

Can you provide the logs and the exact configuration file in a gist or pastebin?

What's markdown?

Sorry about the formatting. Is there a tutorial for beginners?

/var/log/elasticsearch is locked and I can't access the logs.

Any help you can give would be great. Thank you very much.

Hi @marcerickson ,

change your

network.host: 192.168.1.25

into

network.host: "localhost"

and try running your elasticsearch once again.

No luck.

I have Java 12 - does that make a difference?

/var/log/elasticsearch contains 21 files. They are gc.log and gc.log.00 through gc.log.19. Each file is 0 ( zero ) bytes.

I just ran sudo apt update and upgrade. I got this error:
Errors were encountered while processing:
elasticsearch
E: Sub-process /usr/bin/dpkg returned an error code (1)

Elasticsearch still won't run.
