拷贝副本

cd /opt
cp -r  elasticsearch-7.4.0   elasticsearch-7.4.0-itcast1
cp -r  elasticsearch-7.4.0   elasticsearch-7.4.0-itcast2
cp -r  elasticsearch-7.4.0   elasticsearch-7.4.0-itcast3

创建log和data目录

cd /opt
mkdir logs
mkdir  data

授权

chown -R itheima:itheima ./logs
chown -R itheima:itheima ./data

chown -R itheima:itheima ./elasticsearch-7.4.0-itcast1
chown -R itheima:itheima ./elasticsearch-7.4.0-itcast2
chown -R itheima:itheima ./elasticsearch-7.4.0-itcast3

修改第一个节点配置

vim /opt/elasticsearch-7.4.0-itcast1/config/elasticsearch.yml 

cluster.name: itcast-es
node.name: itcast-1 
node.master: true
node.data: true
node.max_local_storage_nodes: 3 
network.host: 0.0.0.0
http.port: 9201
transport.tcp.port: 9700
discovery.seed_hosts: ["localhost:9700","localhost:9800","localhost:9900"]
cluster.initial_master_nodes: ["itcast-1", "itcast-2","itcast-3"]
path.data: /opt/data
path.logs: /opt/logs

修改第二个节点配置

vim /opt/elasticsearch-7.4.0-itcast2/config/elasticsearch.yml

cluster.name: itcast-es
node.name: itcast-2 
node.master: true
node.data: true
node.max_local_storage_nodes: 3 
network.host: 0.0.0.0
http.port: 9202
transport.tcp.port: 9800
discovery.seed_hosts: ["localhost:9700","localhost:9800","localhost:9900"]
cluster.initial_master_nodes: ["itcast-1", "itcast-2","itcast-3"]
path.data: /opt/data
path.logs: /opt/logs

修改第三个节点

vim /opt/elasticsearch-7.4.0-itcast3/config/elasticsearch.yml 

cluster.name: itcast-es
node.name: itcast-3 
node.master: true
node.data: true
node.max_local_storage_nodes: 3 
network.host: 0.0.0.0
http.port: 9203
transport.tcp.port: 9900
discovery.seed_hosts: ["localhost:9700","localhost:9800","localhost:9900"]
cluster.initial_master_nodes: ["itcast-1", "itcast-2","itcast-3"] 
path.data: /opt/data
path.logs: /opt/logs

授权

chown -R itheima:itheima /opt/elasticsearch-7.4.0-itcast1
chown -R itheima:itheima /opt/elasticsearch-7.4.0-itcast2
chown -R itheima:itheima /opt/elasticsearch-7.4.0-itcast3

修改ES的内存

vim /opt/elasticsearch-7.4.0-itcast1/config/jvm.options

-Xms256m
-Xmx256m

vim /opt/elasticsearch-7.4.0-itcast2/config/jvm.options

-Xms256m
-Xmx256m

vim /opt/elasticsearch-7.4.0-itcast3/config/jvm.options

-Xms256m
-Xmx256m

启动节点一

su itheima

cd /opt/elasticsearch-7.4.0-itcast1/bin

./elasticsearch

检查节点状态

http://192.168.23.129:9201/_cat/health?v 

master_not_discovered_exception正常因为还有没启动其他节点

启动节点二

su itheima

cd /opt/elasticsearch-7.4.0-itcast2/bin

./elasticsearch

检查节点状态

http://192.168.23.129:9201/_cat/health?v

status green正常

启动节点三

su itheima

cd /opt/elasticsearch-7.4.0-itcast3/bin

./elasticsearch

检查节点状态

http://192.168.23.129:9201/_cat/health?v

status green正常

使用Kibana管理集群

cp -r /opt/kibana-7.4.0-linux-x86_64   /opt/kibana-7.4.0-linux-x86_64-cluster

修改Kibana的集群配置

vim  kibana-7.4.0-linux-x86_64-cluster/config/kibana.yml

加入以下配置

server.port: 5601
server.host: "0.0.0.0"
server.name: "kibana-itcast"
elasticsearch.hosts: ["http://localhost:9201","http://localhost:9202","http://localhost:9203"]
elasticsearch.requestTimeout: 99999

cd /opt/kibana-7.4.0-linux-x86_64-cluster/bin/

sh kibana --allow-root
