Verifying the OpenSearch Installation on Linux

To verify the OpenSearch installation, in a terminal window, ensure that the following command gives an output:

ps —ef | grep opensearch

After verifying the process, use one of the following methods to verify the OpenSearch installation.

• Run a REST call.

  This example uses the CURL utility for the REST call:

  curl --user <username>:<password> -XGET http://<host>:<port>

  For details about the correct usage for the CURL utility, see your operating system documentation.

• Open a browser and enter the URL: http://<host>:<port>/

  Supply the username and password in the dialog box that appears.

For both the REST command and the browser URL, use these definitions:

• username — the OpenSearch user administrator name that you entered during the DPK setup script installation

• password — the password you entered during the DPK setup script installation

• host — the OpenSearch host name

• port — OpenSearch HTTP (REST) port that you entered during the DPK setup script installation

When using either method, you should see a message similar to the following:

{
  name" : "server.example.com",
  "cluster_name" : "OSCLUSTER",
  "cluster_uuid" : "IvQKVvLjQiKUwBAMk6Hy7w",
  "version" : {
    "distribution" : "opensearch",
    "number" : "3.2.0",
    "build_type" : "zip",
    "build_hash" : "aa8cdda4ea0da22834936ae7f90f8586b9999c43",
    "build_date" : "2024-12-07T13:36:46.831959Z",
    "build_snapshot" : false,
    "lucene_version" : "9.7.0",
    "minimum_wire_compatibility_version" : "7.10.0",
    "minimum_index_compatibility_version" : "7.0.0"
