实战教你ElasticSearch-8.13集群搭建

elasticsearch8.13集群部署

• elasticsearch8.13

• analysis-ik

• elastiknn

环境准备（每台节点都需要修改）
修改系统参数-----https://www.elastic.co/guide/en/elasticsearch/reference/current/system-config.html（官方推荐）

# vim /etc/security/limits.conf
新增内容如下：
* hard nofile 65536
* soft nproc 2048
* hard nproc 4096
* soft memlock unlimited
* hard memlock unlimited
elasticsearch soft memlock unlimited
elasticsearch hard memlock unlimited

# vim /etc/sysctl.conf

vm.max_map_count=262144
fs.file-max=655360

# sysctl -p

--修改jvm启动内存--运行内存

#vim /etc/elasticsearch/jvm.options （两个之和不要大过物理内存的百分之50）
-Xms1g
-Xmx1g

安装地址：(https://www.elastic.co/guide/en/elasticsearch/reference/8.13/rpm.html)

sudo rpm -ivh elasticsearch-8.13.0-x86_64.rpm
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service

配置elasticsearch.yml（诸台节点配置）

cluster.name: es-ai_cluster
node.name: es-ai_node7
node.roles: [ master, data ]
path.data: /home/es/data/elasticsearch_813
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
network.publish_host: 192.168.253.8
http.port: 9200
transport.port: 9300
discovery.seed_hosts: ["192.168.254.175", "192.168.252.188", "192.168.253.8"]
#cluster.initial_master_nodes: ["es-ai_node5", "es-ai_node6", "es-ai_node7"] （第一次启动集群需要打开）

http.cors.enabled: true
http.cors.allow-origin: "*"

action.destructive_requires_name: true
bootstrap.memory_lock: true

# Enable security features
xpack.security.enabled: false
xpack.security.transport.ssl.enabled: false
xpack.security.http.ssl.enabled: false

 

配置jvm.options
-Xms8g（添加）
-Xmx8g

安装好es后执行（bootstrap.memory_lock）限制内存
systemctl edit elasticsearch.service
[Service]
LimitMEMLOCK=infinity

运行：

sudo systemctl start elasticsearch.service

插件安装地址：

cd /usr/share/elasticsearch/plugins
elasticsearch-analysis-ik-8.13.0.zip （解压放上面目录）
elastiknn-8.13.0.0.zip
