Setup Elasticsearch in Windows

Table of Contents

Prerequisites

  • In this post we will setup a simple single-node Elasticsearch database in windows using the Elasticsearch zip file
  • Elasticsearch database can be installed to run as a windows service like any other database like Oracle or PostgreSQL

Step 1 - Download Elasticsearch

  • Open a command prompt in the Elasticsearch folder
  • Run Elasticsearch using the command .\bin\elasticsearch.bat
  • Closing the command line will stop Elasticsearch. Hence it is recommended to run Elasticsearch as a windows service

Step 2 - Run Elasticsearch as a windows background service

  • Open a command prompt in the Elasticsearch folder
  • Run the command .\bin\elasticsearch-service.bat install to install the Elasticsearch windows service
  • Run the command .\bin\elasticsearch-service.bat start to start the Elasticsearch database
  • Run the command .\bin\elasticsearch-service.bat stop to stop the database if required
  • Run the command .\bin\elasticsearch-service.bat remove to uninstall the database service if required

Step 3 - Reset the ‘elastic’ user password

  • Open a command prompt in the Elasticsearch folder
  • Run the command .\bin\elasticsearch-reset-password.bat -i -u elastic and reset the password of elastic user

Step 4 - Check if Elasticsearch is running

  • Go to a web browser and open the URL https://localhost:9200
  • Enter the username and password of the elastic user
  • Elasticsearch database details should be displayed. This means that the database is running with the desired elastic user credentials

Change the folder where data is stored

  • By default Elasticsearch data is stored in the data folder of Elasticsearch folder
  • Additional data folders or modification of existing data folder can be done using the elasticsearch.yml file
  • Open elasticsearch.yml file in the config folder of Elasticsearch folder
  • Search for path.data and set it to a single data folder or multiple data folder paths. For example, you can write path.data: "C:\elasticsearch-8.10.2\data" or path.data: ["C:\elasticsearch-8.10.2\data","D:\elastic_data"]

Set the memory limit of Elasticsearch windows service

  • By default only 1 GB is allotted to elasticsearch windows service which can result in errors while running multiple queries or large data queries.
  • The memory limit of elasticsearch windows service can be increased for this purpose
  • Open a command prompt in the Elasticsearch folder
  • Run the command .\bin\elasticsearch-service.bat manager. A configuration window will appear
  • Go to Java tab and set the initial and maximum memory pool values to higher values, say 10 GB (=10240 MB)

Disable HTTPS (Optional)

  • Open elasticsearch.yml file in the config folder of Elasticsearch folder
  • In the xpack.security.http.ssl section, set enabled: false to disable HTTPS

Restrict Elasticsearch access to remote connections (Optional)

  • Open elasticsearch.yml file in the config folder of Elasticsearch folder
  • Set http.host: localhost to disable remote http connections to Elasticsearch. If required LAN IP address can also be used in http.host to restrict the access to only LAN

Change the Elasticsearch port (Optional)

  • By default Elasticsearch runs on port 9200
  • Open elasticsearch.yml file in the config folder of Elasticsearch folder
  • Change http.port to the desired value if required
