Elasticsearch Installation on CentOS7


Hi All, I will explain you how to install Elasticsearch (v 1.7.4) on CentOS7 Operating system.

Bu makalenin Türkçe versiyonu için tıklayınız.

Before, we need to install JVM because Eleasticsearch run on JAVA.

yum install -y java-1.8.0-openjdk.x86_64

elasticsearch

After installation of JAVA, go to https://www.elastic.co and download ES 1.7.4 package.

wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.4.noarch.rpm

elastic

After this step,  continue Elasticsearch installation with rpm -i

rpm -i elasticsearch-1.7.4.noarch.prm

elastic

After installation, we need to run the commands which are needed to run at OS level respectively. At this point, we should pay attention to declare on which NIC, Elasticsearch will work.

Example: In /etc/elasticsearch/elasticsearch.yml configuration file http.bind.host can be edited as “1.1.1.1”.

After declaring the NIC that Elasticsearch will work on it, now we can start the service.

systemctl start elasticsearch

elastic

After starting the server, if you do not change Elasticsearch (ES) configuration, it will write its logs under /var/log/elasticsearch folder.

Before send a request to ES, do a final check to the ports that ES run.

netstat -tulpn

elastic5

After verify the NIC declarations that we did in /etc/elasticsearch/elasticsearch.yml, we can send requests to the ES server.

curl -XGET 192.168.24.102:9200

elastic6

After installation, in order to increase cluster node number by adding a new node to the system, open /etc/elasticsearch/elasticsearch.yml
and write discovery.zen.ping.unicast.hosts: “current ES server IP address”.
