Installing OpenSearch Dashboards (Debian)

Installing OpenSearch Dashboards (Debian)

Installing OpenSearch Dashboards using the Advanced Packaging Tool (APT) package manager simplifies the process considerably compared to the Tarball method. For example, the package manager handles several technical considerations, such as the installation path, location of configuration files, and creation of a service managed by systemd.

Before installing OpenSearch Dashboards you must configure an OpenSearch cluster. Refer to the OpenSearch Debian installation guide for steps.

This guide assumes that you are comfortable working from the Linux command line interface (CLI). You should understand how to input commands, navigate between directories, and edit text files. Some example commands reference the vi text editor, but you may use any text editor available.

Installing OpenSearch Dashboards from a package

Download the Debian package for the desired version directly from the OpenSearch downloads page. The Debian package can be downloaded for both x64 and arm64 architectures.

From the CLI, install using dpkg.

# x64
sudo dpkg -i opensearch-dashboards-2.15.0-linux-x64.deb
# arm64
sudo dpkg -i opensearch-dashboards-2.15.0-linux-arm64.deb

After the installation completes, reload the systemd manager configuration.
```
 sudo systemctl daemon-reload
```

Enable OpenSearch as a service.

 sudo systemctl enable opensearch-dashboards

Start the OpenSearch service.

 sudo systemctl start opensearch-dashboards

Verify that OpenSearch launched correctly.

 sudo systemctl status opensearch-dashboards

Fingerprint verification

The Debian package is not signed. If you would like to verify the fingerprint, the OpenSearch Project provides a .sig file as well as the .deb package for use with GNU Privacy Guard (GPG).

Download the desired Debian package.

curl -SLO https://artifacts.opensearch.org/releases/bundle/opensearch-dashboards/2.15.0/opensearch-dashboards-2.15.0-linux-x64.deb

Download the corresponding signature file.

curl -SLO https://artifacts.opensearch.org/releases/bundle/opensearch-dashboards/2.15.0/opensearch-dashboards-2.15.0-linux-x64.deb.sig

Download and import the GPG key.

curl -o- https://artifacts.opensearch.org/publickeys/opensearch.pgp | gpg --import -

Verify the signature.

gpg --verify opensearch-dashboards-2.15.0-linux-x64.deb.sig opensearch-dashboards-2.15.0-linux-x64.deb

Installing OpenSearch Dashboards from an APT repository

APT, the primary package management tool for Debian–based operating systems, allows you to download and install the Debian package from the APT repository.

Install the necessary packages.

sudo apt-get update && sudo apt-get -y install lsb-release ca-certificates curl gnupg2

Import the public GPG key. This key is used to verify that the APT repository is signed.

 curl -o- https://artifacts.opensearch.org/publickeys/opensearch.pgp | sudo gpg --dearmor --batch --yes -o /usr/share/keyrings/opensearch-keyring

Create an APT repository for OpenSearch.

echo "deb [signed-by=/usr/share/keyrings/opensearch-keyring] https://artifacts.opensearch.org/releases/bundle/opensearch-dashboards/2.x/apt stable main" | sudo tee /etc/apt/sources.list.d/opensearch-dashboards-2.x.list

Verify that the repository was created successfully.
```
 sudo apt-get update
```
With the repository information added, list all available versions of OpenSearch:
```
sudo apt list -a opensearch-dashboards
```
Choose the version of OpenSearch you want to install:
- Unless otherwise indicated, the latest available version of OpenSearch is installed.
```
sudo apt-get install opensearch-dashboards
```
- To install a specific version of OpenSearch Dashboards, pass a version number after the package name.
```
# Specify the version manually using opensearch=<version>
sudo apt-get install opensearch-dashboards=2.15.0
```

Once complete, enable OpenSearch.

 sudo systemctl enable opensearch-dashboards

Start OpenSearch.

 sudo systemctl start opensearch-dashboards

Verify that OpenSearch launched correctly.

 sudo systemctl status opensearch-dashboards

Exploring OpenSearch Dashboards

By default, OpenSearch Dashboards, like OpenSearch, binds to localhost when you initially install it. As a result, OpenSearch Dashboards is not reachable from a remote host unless the configuration is updated.

Open opensearch_dashboards.yml.

 sudo vi /etc/opensearch-dashboards/opensearch_dashboards.yml

Specify a network interface that OpenSearch Dashboards should bind to.

 # Use 0.0.0.0 to bind to any available interface.
 server.host: 0.0.0.0

Save and quit.
Restart OpenSearch Dashboards to apply the configuration change.
```
 sudo systemctl restart opensearch-dashboards
```
From a web browser, navigate to OpenSearch Dashboards. The default port is 5601.
Log in with the default username admin and the default password admin. (For OpenSearch 2.12 and later, the password should be the custom admin password)
