Introduction

Elasticsearch and Kibana are powerful tools for data indexing, searching, and visualization. Elasticsearch is a distributed, RESTful search engine that can handle large volumes of data, while Kibana is a web-based visualization platform for Elasticsearch. In this guide, we will show you how to install Elasticsearch and Kibana on Ubuntu 18.04/16.04 and Debian 9/8. We will also provide some code samples for using Elasticsearch with PHP clients.

Installing Elasticsearch and Kibana

Step 1: Install Java
Elasticsearch and Kibana require Java to be installed on the system. To check if Java is already installed on your system, run the following command:


java -version

If Java is not installed, you can install it by running the following command:

2. Add the Elasticsearch repository:


echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list

3. Update the package list:


sudo apt-get update

4. Install Elasticsearch:


sudo apt-get install elasticsearch

5. Start and enable Elasticsearch:

Using Elasticsearch with PHP Clients

Here’s an example of using Elasticsearch with the PHP client:


require 'vendor/autoload.php';

$client = Elasticsearch\ClientBuilder::create()->build();
$params = [
 'index' => 'my_index',
 'type' => 'my_type',
 'id' => 'my_id',
 'body' => ['testField' => 'abc']
];

$response = $client->index($params);
print_r($response);
