Complete elasticsearch yml file is not downloaded

Hi , I have installed Elasticsearch (8.3) with rpm repo and it installed properly. While setting up the authentication I have faced some challenges and i have uninstalled Elasticsearch.

command used to remove elasticsearch- "yum remove elasticsearch "
and then removed all the files from server.

Again i have installed the same version and used same steps. But this time is didnt install properly.
In Elasticsearch.yml file security related parameter are not present.

#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------
# The following settings, TLS certificates, and keys have been automatically
# generated to configure Elasticsearch security features on 28-06-2022 06:17:27

# Allow HTTP API connections from anywhere

#----------------------- END SECURITY AUTO CONFIGURATION -------------------------

This section is completely missing in Elasticsearch.yml file.

Even if I start Elasticsearch its not showing any information about elastic user in the logs.

So default user credentials and TLS setting are not coming.

Looks like I didn't uninstall the Elasticsearch properly.

Any idea how to resolve this issue.

Unless you do a yum purge then files will likely still exist.
