Multi nodes question

#1

Hey there,
I’m currently running a Graylog OVA and everything is smooth, perfect.
I would like to add a second nodes to my project however I can’t seem to be able to find proper documentation on the subject.
Could anyone be able to help me a little bit?
I’m currently running two OVA and my goal is to make the node from the second OVA accessible in the first OVA.
To my understanding, from reading the config files it should be simple. But somehow I can’t get the second node to show up.
Is the following the only line to change in the graylog.config files?
# The HTTP URI of this Graylog node which is used to communicate with the other Graylog nodes in the cluster and by all
# clients using the Graylog web interface.
#
# The URI will be published in the cluster discovery APIs, so that other Graylog nodes will be able to find and connect to this Graylog node.
#
# This configuration setting has to be used if this Graylog node is available on another network interface than $http_bind_address,
# for example if the machine has multiple network interfaces or is behind a NAT gateway.
#
# If $http_bind_address contains a wildcard IPv4 address (0.0.0.0), the first non-loopback IPv4 address of this machine will be used.
# This configuration setting must not contain a wildcard address!
#
# Default: http://$http_bind_address/
http_publish_uri = http://x.x.x.x:9000/ (Proper ip here)

Please, help a noob out :wink:

Tap,

First step , learn to build from source, read http://docs.graylog.org/en/3.0/pages/installation/os/ubuntu.html

Set up at least three nodes, clustering requires 3 nodes for mongodb replica set

  1. Install base operating system plus java making sure they are statically addressed with DNS working.
  2. Install mongodb on each and create replica set - just google.
  3. Install elasticsearch and create a cluster. Remember to set a goog password and firewall rules so that only each node can access each other on elasticsearch ports
  4. Install graylog-server on first node of cluster ( same one as mongodb master node) with master set to true in server.conf
  5. Install graylog-servers on other nodes with master=false.

Remember to read about security issues for production use!!!

Cheers

Do I need to understand that it is not possible using the OVA?
Thanks for your reply, i’ll have to do that then!

Tap,

More pain and less configurable.

Start by building a single node and using ova configuration as a reference.
