Building a Cluster / Adding a node

Elastic Stack Elasticsearch
1

Is there a place where someone can point me to a simple set of instructions
for adding a node to an Elastic Search cluster?

I think I understand Sharding and Nodes and that's what the documents do is
talk about them.

But what I don't understand is...

How do install ElasticSearch on the second node.
If I'm only able to have a two node cluster that will be both a failover
and maybe some perf boost, how do I ensure that I've set all my settings
correctly. (Looks like my rivers setup 4 shards). Are there any best
practices etc

I've been googling my fingers off and no luck finding what i'm looking for.

If I copy the elastic search folder from one machine to another... how can
i use that to make a replica.

Hey, it is as simple as running the first node. Just install ES, select a
cluster name for the nodes, start it on the nodes, and let the node
discovery join the nodes. I recommend odd numbers and at least 3 nodes to
avoid a split brain.

Or did I miss something?

I'm doing this in windows.

I'm crossing internal domains for each node so I thought I'd have to tell
something somewhere that there is another node.

Also I probably want it configured the same way.

Also I don't see where I select a cluster name for the nodes.

With the single node install all I did was... .install and magic happened.
I like magic.

I would love if it I just told ES this node to install onto the new node
and it did all of that for me as long as I have drive letter access etc.

Ok so I looked at the config file and found this:

cluster.name - which you are saying I set it to the same on both
machines... got it.

discovery.zen.ping.unicast.hosts: ["host1", "host2:port"] --- since I
am not on the same network in this case they are in different but
accessible domains (crossing DIT and SIT areas... don't get me started).
do I put in the URL of the other engine into this in the elasticsearch for
each one and point it to each other? Like so

First ES node
discovery.zen.ping.unicast.hosts: ["node2.dit.domain.com:9200"]

Second ES node
discovery.zen.ping.unicast.hosts: ["node1.sit.domain.com:9200"]

This leads me to other questions:

Do I have to install plugins on each node individually?

I'm assuming the data figures out how to get to the nodes on it's own.

I've seen properties in the ElasticSearch.net code that would allow me to
do some kind of discovery for nodes as well in the event one is down.

If you just downloaded and started ES then your settings will be default
ones.

Change cluster.name to something that isn't elasticsearch, and make sure it
is the same on both nodes.
Just list both hosts under discovery.zen.ping.unicast.hosts. Also make sure
you disable multicast at the same time.

Plugins need to be installed on all nodes if you want to access them via
any node, however some plugins need to be installed on all hosts
regardless, so check the docs.

On my initial host (host1) I changed my cluster.name to

cluster.name: ESMyName

Which in elasticsearchhead it is showing as the new name.

I also uncommented::

discovery.zen.ping.multicast.enabled: false

And added

discovery.zen.ping.unicast.hosts: ["host2.mydomain.com:9200"]

on the new node I did the same

discovery.zen.ping.unicast.hosts: ["host1.mydomain.com:9200"]

On host1 ESHead says... cluster heath: yellow (24 of 48)
On host2 ESHead says... clusert heath: yellow (1 of 2)

I see no way to tell that they are attached or that they know about each
other.

The name of the other node isn't showing up in either version of the head.

Then your nodes have not joined together.

Can you gist/pastebin/etc your configs so we can check them?

Host2 elasticsearch.yml:

On my initial host (host1) I changed my cluster.name to

I also uncommented::

discovery.zen.ping.multicast.enabled: false

And added

discovery.zen.ping.unicast.hosts: ["host2.mydomain.com:9200"]

on the new node I did the same

discovery.zen.ping.unicast.hosts: ["host1.mydomain.com:9200"]

On host1 ESHead says... cluster heath: yellow (24 of 48)
On host2 ESHead says... clusert heath: yellow (1 of 2)

I see no way to tell that they are attached or that they know about each
other.

The name of the other node isn't showing up in either version of the head.

Change cluster.name to something that isn't elasticsearch, and make
sure it is the same on both nodes.
Just list both hosts under discovery.zen.ping.unicast.hosts. Also make
sure you disable multicast at the same time.

Plugins need to be installed on all nodes if you want to access them via
any node, however some plugins need to be installed on all hosts
regardless, so check the docs.

Ok so I looked at the config file and found this:

cluster.name - which you are saying I set it to the same on both

discovery.zen.ping.unicast.hosts: ["host1", "host2:port"] ---
since I am not on the same network in this case they are in different but
accessible domains (crossing DIT and SIT areas... don't get me started).
do I put in the URL of the other engine into this in the elasticsearch for
each one and point it to each other? Like so

First ES node
discovery.zen.ping.unicast.hosts: ["node2.dit.domain.com:9200"]

Second ES node
discovery.zen.ping.unicast.hosts: ["node1.sit.domain.com:9200"]

This leads me to other questions:

Do I have to install plugins on each node individually?

I'm assuming the data figures out how to get to the nodes on it's own.

I've seen properties in the ElasticSearch.net code that would allow me
to do some kind of discovery for nodes as well in the event one is down.

I'm crossing internal domains for each node so I thought I'd have to
tell something somewhere that there is another node.

Also I probably want it configured the same way.

Also I don't see where I select a cluster name for the nodes.

With the single node install all I did was... .install and magic
happened. I like magic.

I would love if it I just told ES this node to install onto the new
node and it did all of that for me as long as I have drive letter access
etc.

I think I understand Sharding and Nodes and that's what the

But what I don't understand is...

How do install Elasticsearch on the second node.
If I'm only able to have a two node cluster that will be both a
failover and maybe some perf boost, how do I ensure that I've set all my

best practices etc

I've been googling my fingers off and no luck finding what i'm

If I copy the Elasticsearch folder from one machine to another...
how can i use that to make a replica.

Just set discovery.zen.ping.unicast.hosts: ["host1.mydomain.com,
host2.mydomain.com"] on both hosts, unless you are changing the port it
will use the default.

Also, cluster.name needs to be exactly the same on both hosts.

Which in elasticsearchhead it is showing as the new name.

I also uncommented::

discovery.zen.ping.multicast.enabled: false

And added

discovery.zen.ping.unicast.hosts: ["host2.mydomain.com:9200"]

on the new node I did the same

discovery.zen.ping.unicast.hosts: ["host1.mydomain.com:9200"]

On host1 ESHead says... cluster heath: yellow (24 of 48)
On host2 ESHead says... clusert heath: yellow (1 of 2)

I see no way to tell that they are attached or that they know about
each other.

The name of the other node isn't showing up in either version of the
head.

If you just downloaded and started ES then your settings will be
default ones.

Change cluster.name to something that isn't elasticsearch, and make
sure it is the same on both nodes.
Just list both hosts under discovery.zen.ping.unicast.hosts. Also
make sure you disable multicast at the same time.

Plugins need to be installed on all nodes if you want to access them
via any node, however some plugins need to be installed on all hosts
regardless, so check the docs.

Ok so I looked at the config file and found this:

cluster.name - which you are saying I set it to the same on both
machines... got it.

discovery.zen.ping.unicast.hosts: ["host1", "host2:port"] ---
since I am not on the same network in this case they are in different but
accessible domains (crossing DIT and SIT areas... don't get me started).
do I put in the URL of the other engine into this in the elasticsearch for
each one and point it to each other? Like so

First ES node
discovery.zen.ping.unicast.hosts: ["node2.dit.domain.com:9200"]

Second ES node
discovery.zen.ping.unicast.hosts: ["node1.sit.domain.com:9200"]

This leads me to other questions:

Do I have to install plugins on each node individually?

I'm assuming the data figures out how to get to the nodes on it's
own.

I've seen properties in the ElasticSearch.net code that would allow
me to do some kind of discovery for nodes as well in the event one is down.

I'm doing this in windows.

I'm crossing internal domains for each node so I thought I'd have
to tell something somewhere that there is another node.

Also I probably want it configured the same way.

Also I don't see where I select a cluster name for the nodes.

With the single node install all I did was... .install and magic
happened. I like magic.

I would love if it I just told ES this node to install onto the new
node and it did all of that for me as long as I have drive letter access
etc.

Hey, it is as simple as running the first node. Just install ES,
select a cluster name for the nodes, start it on the nodes, and let the
node discovery join the nodes. I recommend odd numbers and at least 3
nodes to avoid a split brain.

Or did I miss something?

Is there a place where someone can point me to a simple set of
instructions for adding a node to an Elastic Search cluster?

I think I understand Sharding and Nodes and that's what the
documents do is talk about them.

But what I don't understand is...

How do install Elasticsearch on the second node.
If I'm only able to have a two node cluster that will be both a
failover and maybe some perf boost, how do I ensure that I've set all my
settings correctly. (Looks like my rivers setup 4 shards). Are there any
best practices etc

I've been googling my fingers off and no luck finding what i'm
looking for.

If I copy the Elasticsearch folder from one machine to
another... how can i use that to make a replica.
