Elastic search fail to start

Elastic Stack Elasticsearch
1

Hi everyone, I have this issue with elasticsearch after installing successfully on fresh ubuntu 20.04 server,
sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
sudo systemctl start elasticsearch
I keep getting this message
"Job for elasticsearch.service failed because the control process exited with error code.
See “systemctl status elasticsearch.service” and “journalctl -xe” for details.’

my local PC/webserver has 4GB xeon cpu 120GB SSD and of ram I have tried editing the file /etc/elasticsearch/elasticsearch.ymlnetwro changing network. To host local host or 0.0.0.0 port 9200 same results even editing /etc/elasticsearch/jvm.options -Xms1g -Xmx1g values changing to 2G same thing.
firewall port 9200 is opened. what have I missed? journalctl -u elasticsearch.service
journalctl -xe

can you share your elasticsearch.yml file ?

3

yes here it is .

======================== 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: 192.168.0.10

#

# 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 this node is started:

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

#

#discovery.seed_hosts: ["host1", "host2"]

#

# Bootstrap the cluster using an initial set of master-eligible nodes:

#

#cluster.initial_master_nodes: ["node-1", "node-2"]

#

# For more information, consult the discovery and cluster formation 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

Can you validate the yml file here : http://www.yamllint.com/

5

I did the forum messaging chops the ## , thank you for your assistance I greatly appreciate it, I have not used Linux for over 20 years and now I'm paying the price but trying to catch up as I go.

6

it says valid Valid YAML!

7

I see in your initial message some errors related to the parsing of the yml file

can you share elasticsearch log from /var/log/elasticsearch

9

yes I see that but the file is correct and not sure what is causing the error, do you see anything wrong in the file?

Perfect, here us the error

Try to add this into elasticsearch.yml and start again the node.

What version of elasticsearch ?
This this matrix there is no support for that version of Ubuntu

16

I have tried that same results

17

Can you share again the logs from /var/log/elasticsearch/my-application.log
I guess you are using a single node, need to add this into elasticsearch.yml

discovery.type: single-node

18

[tried that same thing here the result of my-application.log

So Sorry for that, Looks like elasticsearch is not supporting Ubuntu 20.04
The error is that elasticsearch is trying to start machine learning process and taht fails due to unsupported OS.
Adding xpack.ml.enabled: false into elasticsearch.yml should tell es do not try to start ML processes

Welcome to our community @steve2020! It's really helpful if you can please format your code/logs/config using the </> button, or markdown style back ticks. It makes things much easier to read which helps us help you :slight_smile:

We don't yet support Ubuntu 20.04, this is a WIP. I would suggest that you try Ubuntu 18.04.
