How to Install Elasticsearch on EndeavourOS Latest

Elasticsearch is a popular open-source search and analytics engine that supports full-text search, authentication, and permission controls. It is written in Java and provides distributed indexing, search, and analytics capabilities. In this tutorial, we will guide you through the process of installing Elasticsearch on EndeavourOS latest.

Prerequisites

Before starting the installation process, ensure that the following prerequisites are met:

• You have root access to the EndeavourOS server.
• Java is installed on the EndeavourOS server.
• A user with sudo privileges is created on the server.

Step 1: Install Elasticsearch

1. Open the terminal on your EndeavourOS server.
2. Download the Elasticsearch package using the following command:

sudo pacman -S elasticsearch

3. Once the installation is complete, open the Elasticsearch configuration file using a text editor:

sudo nano /etc/elasticsearch/elasticsearch.yml

4. Configure Elasticsearch according to your requirement. Here are some important configurations that you should check:

• cluster.name: The name of the cluster. Make sure that it is unique and meaningful.
• node.name: The name of the node.
• network.host: The IP address or hostname of the network interface that Elasticsearch will bind.
• http.port: The port number that Elasticsearch will listen on for HTTP requests.

5. Save and close the file once the configuration is done.

Step 2: Start Elasticsearch

1. After the configuration is done, start the Elasticsearch service using the following command:

sudo systemctl start elasticsearch.service

2. Verify that Elasticsearch is running using the following command:

systemctl status elasticsearch.service

If Elasticsearch is running, you should see the following output:

● elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: disabled)
   Active: active (running) since Wed 2022-01-01 12:34:56 PST; 1min 5s ago

Step 3: Verify Elasticsearch Installation

1. Verify that Elasticsearch is listening on the default port number (9200) using the following command:

curl -X GET "http://localhost:9200/"

If Elasticsearch is properly configured, you should see the following output:

{
  "name" : "node-1",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "X-XXXXX-XXXX-XXXX-XXXXX",
  "version" : {
    "number" : "7.16.3",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "XXXXXXX",
    "build_date" : "2022-01-05T11:34:06.991000Z",
    "build_snapshot" : false,
    "lucene_version" : "8.10.2",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

This output confirms that Elasticsearch is installed and properly configured on your EndeavourOS server.

Conclusion
