Cluster not reachable

If can’t reach the cluster, it outputs:

OpenSearch Security Admin v6
Will connect to localhost:9300
ERR: Seems there is no opensearch running on localhost:9300 - Will exit

Check hostname

By default, uses localhost. If your cluster runs on any other host, specify the hostname using the -h option.

Check the port

Check that you are running against the transport port, not the HTTP port.

By default, uses 9300. If your cluster runs on a different port, use the -p option to specify the port number.

None of the configured nodes are available

If can reach the cluster, but can’t update the configuration, it outputs this error:

Contacting opensearch cluster 'opensearch' and wait for YELLOW clusterstate ...
Cannot retrieve cluster state due to: None of the configured nodes are available: [{#transport#-1}{mr2NlX3XQ3WvtVG0Dv5eHw}{localhost}{}]. This is not an error, will keep on trying ...
  • Try running with -icl and -nhnv.

    If this works, check your cluster name as well as the hostnames in your SSL certificates. If this does not work, try running with --diagnose and see diagnose trace log file.

  • Add --accept-red-cluster to allow to operate on a red cluster.

Check cluster name

By default, uses opensearch as the cluster name.

If your cluster has a different name, you can either ignore the name completely using the -icl option or specify the name using the -cn option.

Check hostname verification

By default, verifies that the hostname in your node’s certificate matches the node’s actual hostname.

If this is not the case (e.g. if you’re using the demo certificates), you can disable hostname verification by adding the -nhnv option.

Check cluster state

By default, only executes if the cluster state is at least yellow.

If your cluster state is red, you can still execute, but you need to add the -arc option.

Check the security index name

By default, the security plugin uses opensearch_security as the name of the configuration index. If you configured a different index name in opensearch.yml, specify it using the -i option.

“ERR: DN is not an admin user”

If the TLS certificate used to start isn’t an admin certificate, the script outputs:

Connected as,OU=SSL,O=Test,L=Test,C=DE
ERR:,OU=SSL,O=Test,L=Test,C=DE is not an admin user

You must use an admin certificate when executing the script. To learn more, see Configure admin certificates.

Use the diagnose option

For more information on why is not executing, add the --diagnose option:

./ -diagnose -cd -cacert ... -cert ... -key ... -keypass ...

The script prints the location of the generated diagnostic file.
