How to install Elasticsearch?

In this post, lets discus about the installation of Elasticsearch on windows.

The requirement for installing Elasticsearch is a Java. Elasticsearch recommends its user to install latest version of Java.

We can get the latest version of Java from the official website www.java.com.

The Elasticsearch package can be downloaded from the official link https://www.elastic.co/downloads/elasticsearch

The packages are available as follows,

Elasticsearch installation

Download zip file to install Elasticsearch on windows.

Unzip the package and place it appropriate directory as needed.

To run the Elasticsearch, traverse to elasticsearch\bin path in command prompt and open the elasticsearch.bat file.

By doing this, the Elasticsearch service will start running in command prompt. But when we close the command prompt, the Elasticsearch service will stop running.

So, the Elasticsearch should be installed as window service by running the following command in command prompt

elasticsearch\bin>service install

When command executed successfully, we will receive message as “The service elasticsearch-service-x64 has been installed”.

The Elasticsearch service can be start by using the following command

elasticsearch\bin>service start

Once the service is started, we can confirm it by browsing URL http://localhost:9200/ in browser.

If the service started successfully, it will return 200 status.

 

Note:

Sometimes, we get error while starting windows service which is installed using service install command.

Mostly, it will be because of JVM conflict with the environment variable %JAVA_HOME%. We can fix this by running the following command in command prompt which will set the default JVM to our elasticsearch service (reference)

elasticsearch-service-x64.exe //US//YOUR_SERVICE_NAME --Jvm auto

example:

elasticsearch-service-x64.exe //US//my-elastic-service --Jvm auto

where my-elastic-service is the custom name of our elasticsearch service.
