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:
sudo apt-get update
sudo apt-get install default-jre

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);
