Build an Elasticsearch cluster in CentOS 7

Build an Elasticsearch cluster in CentOS 7

Environment Description:
Server (System Version CentOS 7)
Elasticsearch version: elasticsearch-6.2.2
Elasticsearch Directory:/home/soft/

192.168.33.10 master
192.168.33.11 master data
192.168.33.12 master data

1. Create an elasticsearch account [elasticsearch is used for all three machines]
Useradd es
Passwd es

2. Create a data directory And a log directory [all three machines are the same]

Mkdir-p/home/soft/elasticsearch-6.2.2/data/

Mkdir-p/home/soft/elasticsearch-6.2.2/data/logs/

3. modify directory permissions [the same for all three machines]

Chown-R es: es/home/soft/elasticsearch-6.2.2

4. modify configuration information

I. 192.168.33.10 configuration information:
Cluster. name: my-application
Node. name: node-192-168-33-10
Path. data:/home/soft/elasticsearch-6.2.2/esData/data
Path. logs:/home/soft/elasticsearch-6.2.2/esData/logs
Bootstrap. memory_lock: false
Bootstrap. system_call_filter: false
Network. host: 192.168.33.10
Http. port: 9200
Discovery. zen. ping. unicast. hosts: ["192.168.33.10: 9300", "192.168.33.11: 9300", "192.168.33.12: 9300"]
Discovery. zen. minimum_master_nodes: 2
Gateway. recover_after_nodes: 3
Node. master: true
Node. data: false
Node. ingest: false
Search. remote. connect: false

Ii. 192.168.33.11 configuration information:
Cluster. name: my-application
** Node. name: node-192-168-33-11 **
Path. data:/home/soft/elasticsearch-6.2.2/esData/data/
Path. logs:/home/soft/elasticsearch-6.2.2/esData/logs/
Bootstrap. memory_lock: false
Bootstrap. system_call_filter: false
** Network. host: 192.168.33.11 **
Http. port: 9200
Discovery. zen. ping. unicast. hosts: ["192.168.33.10: 9300", "192.168.33.11: 9300", "192.168.33.12: 9300"]
Discovery. zen. minimum_master_nodes: 2
Gateway. recover_after_nodes: 3
Node. master: true
** Node. data: true **
Node. ingest: false
Search. remote. connect: false

Iii. 192.168.33.12 configuration information
Cluster. name: my-application
** Node. name: node-12 **
Path. data:/home/soft/elasticsearch-6.2.2/esData/data/
Path. logs:/home/soft/elasticsearch-6.2.2/esData/logs/
Bootstrap. memory_lock: false
Bootstrap. system_call_filter: false
** Network. host: 192.168.33.12 **
Http. port: 9200
Discovery. zen. ping. unicast. hosts: ["192.168.33.10: 9300", "192.168.33.11: 9300", "192.168.33.12: 9300"]
Discovery. zen. minimum_master_nodes: 2
Gateway. recover_after_nodes: 3
Node. master: true
Node. data: true
Node. ingest: false
Search. remote. connect: false

4. Start elasticsearch-6.2.2 as An es user [three machines]
./Bin/elasticsearch
After the cluster is successfully started, use CURL to test whether the cluster is successfully built.
Curl http: // 192.168.33.11: 9200/_ cat/nodes? V

Simple setup of Elasticsearch Clusters

At this point, a simple cluster has been successfully built, and now node-12 is the master node.

Note:
The cluster. name values of the three machines must be the same, and the node. name values must be different.

List of problems encountered during startup:

1. Simple setup of Elasticsearch Clusters

Solution:
Vim/etc/security/limits. conf. Add two new lines:
Es soft nofile 65536
Es hard nofile 65536

2. Simple setup of Elasticsearch Clusters

Solution:
When discovery. zen. ping. unicast. hosts is configured, add the port
