noobish question: I am relearning elastic after a hiatus of a couple years. I downloaded the 8.3.3 tarball, uncompressed it and started elasticsearch, (I'm on linux) but I forgot to properly configure elasticsearch.yml.

So I deleted the whole elasticsearch directory and started over, but I kept running into either http.p12 or transport.p12 errors. Also, when I started over, I did not get the first time run information showing the password for the elastic user, HTTP CA certificate, etc.

Googling 'reinstall elasticsearch' and 'recreate transport.p12', I did learn how to recreate the http.p12 and the CA. But I could not find instructions on how to recreate the transport.p12 file.

So my questions are these:

1. If I need to completely blow away the elasticsearch install again, what else beside deleting the directory do I need to do so that elasticsearch thinks it is a fresh, new install?

2. How do I recreate the transport.p12? The new http.p12 works just fine.

Thanks

OK, nevermind.

Looks like the transport.p12 was just an arbitrary naming convention.

If you rebuild and have the p12 errors, use these links to resolve:
