ELK之elasticsearch版本678集群设置

　　ELK7版本搭建参考：https://www.cnblogs.com/minseo/p/10948632.html

　　2024-03-12补充 elasticsearch6版本设置如下

　　node-1

cluster.name: my-es
node.name: prd-es-kibana-01
path.data: /data/es-data
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200

#集群个节点IP地址，也可以使用els、els.shuaiguoxia.com等名称，需要各节点能够解析
discovery.zen.ping.unicast.hosts: ["172.16.90.11", "172.16.90.12"]
#集群节点数
discovery.zen.minimum_master_nodes: 2
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

　　node-2

cluster.name: my-es
node.name: prd-es-kibana-02
path.data: /data/es-data
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200

#集群个节点IP地址，也可以使用els、els.shuaiguoxia.com等名称，需要各节点能够解析
discovery.zen.ping.unicast.hosts: ["172.16.90.11", "172.16.90.12"]
#集群节点数
discovery.zen.minimum_master_nodes: 2
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

　　以下为7版本的设置，和6版本有所不同注意区别

　　2024-03-12补充完毕

　　node-1已经安装配置好　　

　　配置文件如下

[root@salt-test conf.d]# sed '/#/d' /etc/elasticsearch/elasticsearch.yml 
cluster.name: my-es
node.name: node-1
path.data: /data/es-data
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
#discovery.seed_hosts: ["192.168.1.4", "192.168.1.5"]
cluster.initial_master_nodes: ["node-1"]
http.cors.enabled: true
http.cors.allow-origin: "*"

　　

　　新建主机node-2修改elasticsearch配置文件

/etc/elasticsearch/elasticsearch.yml 

　　

#集群名需要和node-1一致
cluster.name: my-es
#node名
node.name: node-2
path.data: /data/es-data
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
#集群中两个节点的IP
discovery.seed_hosts: ["192.168.1.4", "192.168.1.5"]
cluster.initial_master_nodes: ["node-1"]
http.cors.enabled: true
http.cors.allow-origin: "*"

　　启动elasticsearch

　　查看节点1和2

　　数据会自动从节点1同步至节点2

　　在head查看

elasticsearch8.9.0版本集群设置

下载安装8.9.0版本不详述下面是集群的两个节点的配置文件

node-1

cluster.name: my-es

http.host: 0.0.0.0　

配置文件解析

两个节点配置不一样的地方有两处

 

# 集群名,两个节点配置需一致
cluster.name: my-es
# 集群node名两个节点配置不一样
node.name: node-1
# 数据和日志路径，默认撇嘴
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
# 集群的节点本次两个节点
discovery.seed_hosts: ["192.168.3.59", "192.168.3.60"]
# 认证默认为true手动设置为false取消认证
xpack.security.enabled: false
xpack.security.enrollment.enabled: false
