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
