How to Install Elastic Stack on CentOS 7

In this article, We are going to perform, How to Install Elastic Stack on CentOS 7 or any Cloud Instance like Amazon EC2, Azure VM, Google Compute Engine,etc with preinstalled CentOS 7.

Now ELK Stack renamed as Elastic Stack with the addition of FileBeats.


ELK is the combination of  three open source projects: Elasticsearch, Logstash, Kibana and Filebeat. Elasticsearch is a search and analytics engine. Logstash is a server‑side logs processing pipeline that transport logs from multiple sources simultaneously, transforms it, and then sends it to a “stash” like Elasticsearch. Kibana is to visualize logs with charts and graphs from Elasticsearch.

WorkFlow  =  ElasticSearch  —> Kibana  —> Logstash —> Filebeat

Next Insert/Update as shown below in Logstash Configuration

$ sudo nano /etc/logstash/conf.d/logstash.conf
output {

  elasticsearch {

    hosts => ["localhost:9200"]

    manage_template => false

    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"



To start logstash services

$ sudo systemctl start logstash

To enable logstash at system startup

 $ sudo systemctl enable logstash

To stop logstash services

$ sudo systemctl stop logstash

To check status of logstash

In the configuration file go to Kibana Section as shown below:

#============================== Kibana =====================================
# uncomment the host and change "localhost to IP"
host: "<IP of server>:5601"

In the configuration file got ElasticSearch Section as shown below:

#-------------------------- Elasticsearch output ------------------------------
# uncommnet the hosts section
hosts: ["localhost:9200"]

To start filebeat services:

$ sudo systemctl start filebeat

To enable filebeat at system startup

$ sudo systemctl enable filebeat

To check status of filebeat services

$ sudo systemctl status filebeat

Now lets check that ElasticSearch is receiving datalog from filebeat using below command

$ sudo curl -XGET 'https://localhost:9200/filebeat-*/_search?pretty'

Finally lets login into kibana portal using

 http:/<ip of the server>:5601

kibana dashboard
