Sorry for the beginner question, but I am having trouble regenerating the certificates that were made at deployment. I'm not familiar with how certificates work so I was hoping there might be a script that just regenerates them? I changed the ip of my elasticsearch server and the certificate was apparently bound to the initial ips. I prematurely deleted the certs inside the /config/certs directory and now I'm stuck. Anyone know how I can fix this without a full reinstall?
Regenerating certificates for Elasticsearch can be done using the Elasticsearch certutil tool.
The basic steps are
Create Transport Certs
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
Create http certs
Move all the certs to the correct directories and make sure they are readable.
Detailed Steps are Here as well
And i have some examples here...
