Install ElasticSearch CentOS

PUBLISHED ON MAY 2, 2020 — HOW-TO, LINUX

I started playing around with elasticsearch and after searching a little bit I found a way to install it quickly and with minimal/default settings

By executing the following steps:

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
vim /etc/yum.repos.d/elasticsearch.repo

You need to add the following:

[Elasticsearch-7]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

Next we just need to run:

yum install -y elasticsearch

Lastly, let’s make a small change on the settings by editing the following file:

vim /etc/elasticsearch/elasticsearch.yml

Update the following line to make it look like this:

 network.host: localhost

Now, please start the service and test it running:

 curl -X GET "localhost:9200/?pretty"

It should return something otherwise something is wrong.
