Installing Elasticsearchedit

Elasticsearch is a real-time, distributed storage, search, and analytics engine. It can be used for many purposes, but one context where it excels is indexing streams of semi-structured data, such as logs or decoded network packets.

The binary packages of Elasticsearch have only one dependency: Java. The minimum supported version is Java 8. To download and install Elasticsearch, use the commands that work with your system (deb for Debian/Ubuntu, rpm for Redhat/Centos/Fedora, mac for OS X, and win for Windows):


sudo apt-get install openjdk-8-jre
curl -L -O
sudo dpkg -i elasticsearch-5.2.2.deb
sudo /etc/init.d/elasticsearch start


sudo yum install java-1.8.0-openjdk
curl -L -O
sudo rpm -i elasticsearch-5.2.2.rpm
sudo service elasticsearch start


# install Java, e.g. from:
curl -L -O
cd elasticsearch-5.2.2


  1. If necessary, download and install the latest version of the Java from
  2. Download the Elasticsearch 5.2.2 Windows zip file from the downloads page.
