Again, you can install Elasticsearch using the tar.gz archive, RPM package or from RPM repository. We will discuss the use of RPM and RPM repository in this guide.

Install Elasticsearch 7.x using RPM Repository

To install Elasticsearch 7.x on CentOS 7/Fedora 29 using the RPM repository, perform system update before proceeding

On CentOS 7

yum update
yum upgrade

On Fedora 29

dnf update
dnf upgrade

Import the Elasticsearch PGP Key

Once the system upgrade is done, run the command below to import the Elasticsearch PGP Signing Key.

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

Add Elasticsearch 7.x RPM Repository

To add the Elasticsearch 7.x repository that will allow you to install Elasticsearch 7.0.0 on CentOS 7/Fedora 29, run the command below

cat > /etc/yum.repos.d/elastic-7.x.repo << EOF
[elasticsearch-7.x]
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
EOF

Once you have created the Elasticsearch repository, update your system and install Elasticsearch.

On CentOS 7

yum update
yum install elasticsearch

On Fedora 29

dnf update
dnf install elasticsearch

If the installation is successful, you should be able to see such an output snippet.

Complete!

Install Elasticsearch 7.x using RPM package

To manually install Elasticsearch 7.0 on CentOS 7/Fedora 29 using RPM package, download the RPM package.

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.0.0-x86_64.rpm

Next, download the checksum for verifying the integrity of the RPM package.

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.0.0-x86_64.rpm.sha512

Run the integrity check by comparing the checksums. Before that, install perl-Digest-SHA -y which provides shasum for checksum comparison.

yum install perl-Digest-SHA -y
dnf install perl-Digest-SHA -y
shasum -a 512 -c elasticsearch-7.0.0-x86_64.rpm.sha512

If all is well, then you will get an OK output.

elasticsearch-7.0.0-x86_64.rpm: OK

Next, Install Elasticsearch 7.0.0 on CentOS 7/Fedora 29

On CentOS 7

sudo yum localinstall elasticsearch-7.0.0-x86_64.rpm

On Fedora 29

sudo dnf install ./elasticsearch-7.0.0-x86_64.rpm

Running Elasticsearch

Once the installation is done, you can start elasticsearch service by executing;

systemctl daemon-reload
systemctl start elasticsearch

To stop or configure elasticsearch service to start automatically on system boot, run the commands below respectively.

systemctl stop elasticsearch
systemctl enable elasticsearch

To check the status;

systemctl status elasticsearch

You can also use curl to check the status.

curl -X GET "localhost:9200/"
{
  "name" : "Cent7.example.com",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "_C5MBUk4So6v7e0qQvRv_g",

    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

If FirewallD is running, you need to open tcp port 9200 on it.

sudo firewall-cmd --add-port=9200/tcp --permanent
sudo firewall-cmd --reload

Great, that is all it takes to install Elasticsearch 7.0 on CentOS 7/Fedora 29. We will cover more about Elastic Stack in our next tutorials. Enjoy.
