Elasticsearch 7 Quickinstall

Install/uninstall script for Elasticsearch and Kibana running on Ubuntu 20.04.

Configure them as service running on localhost and install Elasticsearch Ingest-Attachment Plugin. Tested with Elasticsearch 7.17.4.

Install Elasticsearch and Kibana

#!/bin/bash
apt install elasticsearch kibana -y
systemctl daemon-reload
systemctl enable elasticsearch.service
systemctl enable kibana.service
echo y | elasticsearch-plugin install ingest-attachment

echo "patching elasticsearch.yml"
sed -i 's/#network\.host: 192\.168\.0\.1/network\.host: 127\.0\.0\.1/g' /etc/elasticsearch/elasticsearch.yml
sed -i 's/#http\.port: 9200/http\.port: 9200/g' /etc/elasticsearch/elasticsearch.yml
egrep "127|9200" /etc/elasticsearch/elasticsearch.yml

service elasticsearch start
service kibana start

echo "INSTALLED."

locate elasticsearch
locate kibana
