Configuring Elasticsearch on Magento 2 can significantly improve the search functionality and overall performance of your e-commerce website. Elasticsearch is a powerful open-source search and analytics engine that can enhance the search experience for your customers. Follow these steps to configure Elasticsearch on Magento 2:

Step 1: Install Elasticsearch

Before configuring Elasticsearch on Magento 2, you need to install it on your server. You can download the latest version of Elasticsearch from the official website (https://www.elastic.co/downloads/elasticsearch) and follow the installation instructions provided.

Step 2: Install Elasticsearch PHP Client

Magento 2 uses the Elasticsearch PHP client to communicate with the Elasticsearch server. You can install the Elasticsearch PHP client using Composer:

composer require elasticsearch/elasticsearch

Step 3: Configure Elasticsearch in Magento 2 Admin Panel

Login to Magento Admin:

  • Go to your Magento 2 Admin Panel.

Navigate to Stores > Configuration:

  • In the left-hand menu, go to Stores and click on Configuration.

Expand Catalog:

  • Under the Catalog section in the left sidebar, click on Catalog.

Configure Elasticsearch:

  • Open the Catalog Search section.
  • Choose Elasticsearch as the Search Engine.
  • Expand the Elasticsearch options.

Enter Elasticsearch Server Hostname:

  • Enter the hostname of your Elasticsearch server in the Elasticsearch Server Hostname field (usually localhost if it's on the same server).

Enter Elasticsearch Server Port:

  • Specify the port number on which Elasticsearch is running (default is 9200).

Enter Elasticsearch Index Prefix:

  • Set an index prefix for Magento (e.g., magento2).

Configure Elasticsearch Server Timeout:

  • Set the Elasticsearch Server Timeout to an appropriate value.

Test the Connection:

  • Click on the Test Connection button to ensure that Magento can connect to your Elasticsearch server successfully.

Save Config:

  • Save the configuration settings.

Step 4: Reindexing

After configuring Elasticsearch, you need to reindex your Magento 2 store to apply the changes:

SSH into your server:

  • Use SSH to access your server.

Navigate to Magento root directory:

  • Change your directory to the Magento root directory.

Reindex:

  • Run the following command to reindex your data:
bin/magento indexer:reindex`

Step 5: Clear Cache

Clear the Magento cache to make sure that the changes take effect:

bin/magento cache:clean

Step 6: Verify Elasticsearch Integration

Visit your Magento 2 storefront and perform a search to ensure that Elasticsearch is now powering the search functionality.

Congratulations! You have successfully configured Elasticsearch on Magento 2, enhancing the search capabilities of your e-commerce website.
