How to install ElasticSearch 7 on Almalinux 8, RockyLinux8 or RHEL 8

First of all, you should make sure you have no other ElasticSearch versions installed.

If you want to remove an old installation, please apply the following first:

yum -y remove elasticsearch

rm -rf /var/lib/elasticsearch

rm -rf /etc/elasticsearch


Fresh Elastic Search 7 Installation

Download and install the public signing key:

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


Create File elasticsearch.repo

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

 

Edit the file

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


Add the following content to it:

[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

autorefresh=1
type=rpm-md

 

Install ElasticSearch

yum install -y --enablerepo=elasticsearch elasticsearch

 

 

After installation, Edit this config file

nano /etc/elasticsearch/jvm.options

 

Comment out this line by adding # at the beginning, or remove it

#-Djava.io.tmpdir=${ES_TMPDIR}

 

Add this line right after the above line or anywhere in the config file:

-Djava.io.tmpdir=/home/elasticsearch

 

Save and exit.

 

Create /home/elasticsearch folder and add it to the group elasticsearch

mkdir /home/elasticsearch

chown -R elasticsearch:elasticsearch /home/elasticsearch/

 

Install Java

yum -y install java-1.8.0-openjdk

 

Enable and Start Elastic search

systemctl enable elasticsearch

systemctl start elasticsearch

 

Check elasticsearch status

Test elasticsearch to make sure it's listening to port 9200

curl GET 'localhost:9200'

 

Done!
