Three virtual machines are used in this experiment

192.168.209.168

192.168.209.169

192.168.209.170

Cp / usr/elasticsearch-6.2.3/config/elasticsearch.yml / usr/elasticsearch-6.2.3/config/elasticsearch.yml.bak

Vi / usr/elasticsearch-6.2.3/config/elasticsearch.yml

Cluster.name: ES_Cluster_Pcdog

Node.name: 192.168.209.168

Path.data: / usr/elasticsearch-6.2.3/data

Path.logs: / usr/elasticsearch-6.2.3/logs

Network.host: 192.168.209.168

Node.master: true

Node.data: true

Discovery.zen.ping.unicast.hosts: ["192.168.209.168", "192.168.209.169", "192.168.209.170"]

Discovery.zen.minimum_master_nodes: 3

Discovery.zen.fd.ping_timeout: 120s

Discovery.zen.fd.ping_retries: 6

Discovery.zen.fd.ping_interval: 30s

Cluster.routing.allocation.cluster_concurrent_rebalance: 40

Cluster.routing.allocation.node_concurrent_recoveries: 40

Cluster.routing.allocation.node_initial_primaries_recoveries: 40

Bootstrap.memory_lock: false

Bootstrap.system_call_filter: false

Check the configuration and filter out comments

Cat elasticsearch.yml | grep-v "^ #"

Node 168Startup

. / bin/elasticssearch

Cluster status yellow, because the other 2 sets have not been started yet.

[2018-04-20T11:36:16000] [INFO] [o.e.c.r.a.AllocationService] [192.168.209.168] Cluster health status changed from [RED] to [YELLOW] (reason: [shards started [[logstash-2018.04.18] [1]]...]).

Copy the configuration file to the other 2 nodes

Scp elasticsearch.yml 192.168.209.169:/usr/elasticsearch-6.2.3/config

Scp elasticsearch.yml 192.168.209.170:/usr/elasticsearch-6.2.3/config

Then start elasticssearch in their respective node

Node 002

Node 003

In the master node directory / usr/elasticsearch-6.2.3/logs

You can see the cluster log

Tail-f ES_Cluster_Pcdog.log

The Nima log is not updated. If you go to the other two nodes, both node have reported errors. Is it because of the machine I cloned? Let me fix a mistake.

[2018-04-20T11:49:10794] [INFO] [o.e.d.z.ZenDiscovery] [192.168.209.169] failed to send join request to master [{192.168.209.168} {- aU5102ETMW8isf85FWEHA} {192.168.209.168} {192.168.209.168} {192.168.209.168} {192.168.209.168} {192.168.209.168], reason [RemoteTransportException [[192.168.209.168] [192.168.209.168] [internal:discovery/zen/join] Nested: IllegalArgumentException [can't add node {192.168.209.169} {- aU5102ETMW8isf85FWEHA} {192.168.209.169} {192.168.209.169} {192.168.209.169}, found existing node {192.168.209.168} {- aU5102ETMW8isf85FWEHA} {192.168.209.168} {192.168.209.168} {192.168.209.168} {192.168.209.168} 9300} with the same id but is a different node instance];]

It turns out that there is the original data in data. Kill it.

[pactera@ELK_002 data] $pwd

/ usr/elasticsearch-6.2.3/data

[pactera@ELK_002 data] $rm-rf nodes/

All three nodes are normal.

Node 168Discovery master role 169,

Node 169The status changes from yellow to green

Node 170,169 roles found in master

Later I need to study how to elect the master process, this cluster 3 master 3 data, the actual production should be 2 master and then multiple data.
