How to install Elasticsearch On Debian Linux


The objective is to provide you with a simple to follow steps on how to install Elasticsearch on Debian Linux. The guide does not delve into Elasticsearch configuration as this is a tale for another time.

Operating System and Software Versions

  • Operating System: – Debian 9 (Stretch)
  • Software: – Elasticsearch 5.2.0


Privileged access to your Debian system will be required




  • # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command
  • $ – requires given linux commands to be executed as a regular non-privileged user


Prerequisites installation

To begin, install all required prerequisites listed below. The net-tools package is optional and is used for testing purposes only.

# apt update 
# apt install openjdk-8-jdk-headless net-tools wget

Download Elasticsearch

At this stage, we need to download the Elasticsearch Debian package. At the time of writing, only Elasticsearch 5.2 is available. Feel free to replace the below link with version 6.0 download URL if it is available.

wget --no-check-certificate

Install Elasticsearch

Use dpkg command to install the previously downloaded elasticsearch-5.2.0.deb:

# dpkg -i elasticsearch-5.2.0.deb

Start and Enable Elasticsearch

Tos start and enable Elasticsearch on Debian systemd system execute:

# systemctl start elasticsearch
# systemctl enable elasticsearch

Confirm Installation

The journalctl command should now list Elasticsearch as started:

# journalctl | tail
Feb 11 08:59:02 linuxconfig systemd[1]: Reached target Network is Online.
Feb 11 08:59:02 linuxconfig systemd[1]: Starting Elasticsearch...
Feb 11 08:59:02 linuxconfig systemd[1]: Started Elasticsearch.

Elasticsearch by default listens on localhost only unless defined differently within /etc/elasticsearch/elasticsearch.yml:

# netstat -ntlp

Elasticgsearch is now available under localhost:9200 URL:

# wget -qO -
  "name" : "p7g80HJ",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "W7iE1jWYSiWL-hG3zMsaFQ",
  "version" : {
    "number" : "5.2.0",
    "build_hash" : "24e05b9",
    "build_date" : "2017-01-24T19:52:35.800Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.0"
  "tagline" : "You Know, for Search"

Install Plugins

Elasticsearch plugin and other relevant binaries are locate under /usr/share/elasticsearch/bin/ directory. Add this directory to your executable PATH:

# export PATH=$PATH:/usr/share/elasticsearch/bin/

To install new Elasticsearch plugins use elasticsearch-plugin command. For example to install “file-based discovery plugin” run:

# elasticsearch-plugin install discovery-file
-> Downloading discovery-file from elastic
[=================================================] 100%   
-> Installed discovery-file
