Problem installing Elasticsearch

Elastic Stack Elasticsearch
6

I got it to work! Here is the summary.

  • When running "elasticsearch.bat", no password or enrollment token is displayed. Below is how I regenerated them.

    • While the script is running, open another command prompt. Run .\bin\elasticsearch-reset-password -u elastic to reset and display the new password. Run .\bin\elasticsearch-create-enrollment-token -s kibana to display the enrollment token
    • Removing all files and unzipping the installer did not help

  • When you see this error below, the Elasticsearch is probably running fine, and something is trying to connect to Elasticsearch using incorrect connection setting

caught exception while handling client http traffic, closing connection Netty4HttpChannel{localAddress=/127.0.0.1:9200, remoteAddress=/127.0.0.1:53413}io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: (unknown_ca) Received fatal alert: unknown_ca

By regenerating the password and enrollment token, I was able to set up Elasticsearch along with Kibana. It turned out that there was a software (my software of course) that was trying to talk to Elasticsearch with incorrect connection setting. After updating the connection setting, my software can now talk to Elasticsearch and see the log in Kibana.

Thank you so much for your help!
