I am having an issue with Elasticsearch starting on Ubuntu 20.04 while trying to start the service doing the following:
systemctl restart elasticsearch
Job for elasticsearch.service failed because a fatal signal was delivered to the control process.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.
Here is a copy of my YML file:
#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: localhost
Set a custom port for HTTP:
#http.port: 9200
Here a copy of the Journalctl:
root@Ubuntu-ELK:/etc/elasticsearch# journalctl -u elasticse arch.service
