As the need arose recently elasticsearch installation and it is not too demanding decided to describe how we can make the installation in a few very simple steps.

So let's get started.

All software requires a minimum version of Java 1.7 So at the beginning we will update the repo and install java.

System update:

yum update

java installation a lot:

yum install java-1.8.0-openjdk.x86_64

If everything went ok after entering the command java -version You should get :

openjdk version "1.8.0_65"
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)

then we grab the key and create a repository elasticsearch

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

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

/etc/yum.repos.d/Elasticsearch.repo file should have a content:

[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

We do instlacji:

yum -y install elasticsearch

chkconfig --add elasticsearch

It remained practically the whole work we made some editing in the same configuration elasticsearch we released it to the world.

We do edit the file /etc / elasticsearch / elasticsearch.yml

nano /etc/elasticsearch/elasticsearch.yml

and change:

# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.rack: r1
#
# ----------------------------------- Paths ------------------------------------

node.name: node 1 should be commented on.

next

# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: IPSERWERA
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, see the documentation at:
# 

Then, from commenting 2 options:

network.host: IPSERWERA and give your server ip and vps

http.port: 9200 – jest to port pod którym widzimy elasticsearch w internecie

after making these changes we can save and run the script.

service elasticsearch start

If everything goes correctly at IPSERWERA:9200 we should see something like this:

{
  "name" : "node-1",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "YYRBLSq4SH2CVVkn1U4Fxw",
  "version" : {
    "number" : "2.4.6",
    "build_hash" : "5376dca9f70f3abef96a77f4bb22720ace8240fd",
    "build_timestamp" : "2017-07-18T12:17:44WITH",
    "build_snapshot" : false,
    "lucene_version" : "5.5.4"
  },
  "tagline" : "You Know, for Search"
}

Everything works perfectly fine 🙂

If you do not see SRON must add a port 9200 do allow firewalla.
