Attempting to enable TLS

Elasticsearch 6.8.12

I have an existing cluster which was set up before x-pack was free. I now want to setup the security "properly". I have used Letsencrypt to install certificates on each of the cluster members and I am following these instructions which are actually for 5.X.

I am currently trying to bring up a single isolated node to do some testing but it dies with the following error:

failed to load plugin class [org.elasticsearch.xpack.core.XPackPlugin]

But when I start up without the xpack configuration I can see all the xpack modules loaded.

2

Can you please post the entire log from node startup.

Whew, like a said a lot of stack history!

8

Did you check that?

9

clearly not : ( I did look through the stack history for clues but I had no idea what I was looking for.

Ah! stack trace is last call at then end -- I searched from the top! Will know for next time!

I mostly use ruby which normally prints them the other way!

I guessed it must be something simple.

Thanks for your help and patience Mark!

OK one step further forward and much improved understanding of decoding Java errors.
I now have this working but there was one more wrinkle I will document...

Once I corrected the filename I got permission errors:

Caused by: java.security.AccessControlException: access denied ("java.io.FilePermission" "/etc/elasticsearch/ssl//secmonprd08.its.auckland.ac.nz/fullchain.pem" "read")

ES docs for 6.8 say of the files "This must be a location within the Elasticsearch configuration directory", but it isn't clear to me exactly what that means in the context of unix file system -- in particular does it include symlinks outside.

The answer appears to be no. I tried putting a symlink 'ssl' in /etc/elasticsearch pointing to /etc/letsencrypt/live/secmonprd08 but this still gave the permission error. However removing the symlink and replacing it with a directory and copying the files into it worked.

As you can see this certificate is from Letsencrypt and is managed by certbot so I have inherited the location and structure of the directories. I am reluctant move the files elsewhere since that will interfere with certbot renewing the certificate but it appears I have no choice.

Certbot does have post-deploy script that will handle this sort of thing.
