Hi, 1) how to add those non-master nodes to this master node. >
Simply make sure that the non-master Graylog nodes are using the same MongoDB database and the exact same password_secret configuration setting as the master node and that they can communicate with each other on port 12900 (default, see rest_listen_uri and rest_transport_uri <https://github.com/Graylog2/graylog2-server/blob/2.0.0/misc/graylog.conf#L35-L45> ). > 2) how web interface will communicate to non-master nodes & whats the > configuration? > The web interface currently needs to communicate with the Graylog master node, so it's the easiest solution to simply run the web interface on the Graylog master node and disable it on the non-master nodes (see https://github.com/Graylog2/graylog2-server/blob/2.0.0/misc/graylog.conf#L79-L81 ). > 3) Without mongodb replica-set is it possible to make graylog cluster? > Yes, it's possible without a MongoDB replica set, although we don't recommend this because MongoDB is an integral part of the Graylog cluster and should also be highly available (which a single node obviously is not). Since MongoDB doesn't require many resources, you could probably just run it on the same machines as your Graylog nodes and create a replica set over those 3 nodes.
