How to Install and Configure Elk - Elastic Search into Centos 7

In this section you will learn How to Install and Configure Elastic Search into Centos 7 part 1

We are going to configure elastic search into three host one master and two slaves

You can see below one master and two slaves on aws console

Step 1: ssh to all hosts and be the root user

               
sudo -i
                
               

Type the following commands to install all packages into all hosts

               
sudo yum update -y
sudo yum install net-tools wget -y

       
                
               

Create repo file

               
cat > /etc/yum.repos.d/es.repo << EOF
[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
EOF                
               

Install Elastic Search

               
sudo yum update -y
sudo yum install elasticsearch -y
              
               

We have configure etc/hosts file

Configure Elasticsearch File: we will edit elasticsearch.yml

               
vi /etc/elasticsearch/elasticsearch.yml
                
               

Edit following code into elasticsearch.yml

Below code for master

               
##master

cluster.name: Cloudera-Sam-Cluster
node.name: cmhost.realmprod.local
discovery.zen.ping.unicast.hosts: discovery.zen.ping.unicast.hosts:["cmhost.realmprod.local", "slave1.realmprod.local", "slave2.realmprod.local"]
node.master: true
node.data: false
network.host: ["cmhost", "localhost"]
path.logs: /var/log/elasticsearch
                
               

Below Code for Slaves

               
#######data node

cluster.name: Cloudera-Sam-Cluster
node.name: slave1.realmprod.local
node.master: false
node.data: true
network.host: ["slave1", "localhost"]
discovery.zen.ping.unicast.hosts: ["cmhost.realmprod.local", "slave1.realmprod.local", "slave2.realmprod.local"]
path.logs: /var/log/elasticsearch



cluster.name: Cloudera-Sam-Cluster
node.name: slave2.realmprod.local
node.master: false
node.data: true
network.host: ["slave2", "localhost"]
discovery.zen.ping.unicast.hosts: ["cmhost.realmprod.local", "slave1.realmprod.local", "slave2.realmprod.local"]
path.logs: /var/log/elasticsearch

                
               

Start Elasticsearch:

               
systemctl daemon-reload
systemctl restart elasticsearch
systemctl status elasticsearch
