Install Elasticsearch

Resources #

Installation #

As of this writing latest version is 7.15. This is how to install the latest version. For installation of previous versions, see the official docs.

Elasticsearch ships with a bundled version of OpenJDK, so it’s no longer necessary to install this separately (unless you want to).

Import the Elasticsearch GPG Key # 

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Installing from the RPM repository #

Create the following file:

touch /etc/yum.repos.d/elasticsearch.repo

Add the following to the file:

cat > /etc/yum.repos.d/elasticsearch.repo << EOF
[elasticsearch]
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=0
autorefresh=1
type=rpm-md
EOF

Note, this sets up the Elasticsearch repository for whatever the latest version of 7.x is. If a newer version of ES has been released, that will be installed instead of v7.15.

Install using yum:

yum install --enablerepo=elasticsearch elasticsearch

Run and enable Elasticsearch with systemd # 

systemctl daemon-reload
systemctl enable elasticsearch
systemctl start elasticsearch

Check that Elasticsearch is running # 

curl -X GET "localhost:9200"

Example:

[root@server:/]$ curl -X GET "localhost:9200"
