ElasticSearch is a powerful search engine that provides full schema-free JSON text search queries over a web interface. It’s multi-platform as it runs well on Linux and Windows operating systems. In order to work, it requires Java to be installed on your server. It’s also open source under the Apache license. Today we are going to show you how to install ElasticSearch on cPanel.
Tutorial: Install ElasticSearch on cPanel
Install Java 1.8
First, check the java version we have:
[firstname.lastname@example.org:~]java -version java version "1.6.0_39" OpenJDK Runtime Environment (IcedTea6 1.13.11) (rhel-184.108.40.206.el6_8-x86_64) OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode) If it is less than 1.8, then remove Java so we can install the new version:
dnf remove java
Download Java latest RPM:
cd /usr/src wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.rpm"
dnf localinstall jdk-8u73-linux-x64.rpm
Verify the new version running:
[email@example.com:~]java -version java version "1.8.0_73" Java(TM) SE Runtime Environment (build 1.8.0_73-b02) Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
Remove the dowloaded rpm file:
rm jdk-8u73-linux-x64.rpm -fv
Installing ElasticSearch on cPanel
Download the GPG-KEY:
rpm --import http://packages.elastic.co/GPG-KEY-elasticsearch
Let’s create elasticsearch repo inside yum:
nano -w /etc/yum.repos.d/elasticsearch.repo
Paste this content inside:
[elasticsearch-2.x] name=Elasticsearch repository for 2.x packages baseurl=http://packages.elastic.co/elasticsearch/2.x/centos gpgcheck=1 gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch enabled=1
dnf install elasticsearch
If you need to tweak elasticsearch, you can do it by editing the main configuration file located at:
Add the service to boot after OS starts, and start the service:
chkconfig --add elasticsearch service elasticsearch start
