To install Elasticsearch in Debian, you can follow these steps:

1. Open the terminal.
2. Add the Elasticsearch GPG key by running the following command:

1

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elasticsearch-keyring.gpg

1. Install the apt-transport-https package if it is not already installed:

1

sudo apt-get install apt-transport-https

1. Add the Elasticsearch repository to the package manager's sources by running the following command:

1

echo "deb [signed-by=/usr/share/keyrings/elasticsearch-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-8.x.list

Note: Replace 8.x in the URL with the Elasticsearch version you wish to install (e.g., 7.x, 6.x).

1. Update the package manager's cache:

1

sudo apt-get update

1. Install Elasticsearch by running the following command:

1

sudo apt-get install elasticsearch

During the installation, you may be prompted to confirm the download and installation of additional packages. Enter 'Y' to proceed.

By default, Elasticsearch will be configured to start automatically when the system boots up. You can adjust its configuration by modifying the /etc/elasticsearch/elasticsearch.yml file.
