Question for connecting between master node and data-node on searchguard

Search Guard
1

Hi, there~~

I have a problem to connect between master-node and data-node. I installed Elasticsearch 6.3 to two computers.

Before installing Searchguard on the master-node on Elasticsearch, It is possible to connect between each elasticsearch as master-node and data-node. But, after installing Searchguard, they can’t be connected.

Data-node was trying to connect with master-node. But, Master-node returned the message as “Someone speaks http plaintext instead of ssl, will close the channel”.

I used Elasticsearch 6.3 on Linux(Ubuntu 18.04).

Please, tell me how to resolve this problem.

I don’t fully understand what you mean with "But, after installing Searchguard, they can’t be connected. "

But anyways, the message

Someone speaks http plaintext instead of ssl, will close the channel

``

means that you are using HTTP instead of HTTPS to connect to Elasticsearch. HTTPS is enabled by default when using the demo installer:
