部署一个ES集群

部署环境

java版本

java version "19.0.2" 2023-01-17
Java(TM) SE Runtime Environment (build 19.0.2+7-44)
Java HotSpot(TM) 64-Bit Server VM (build 19.0.2+7-44, mixed mode, sharing)

elasticsearch版本：8.6.2

主机一台

 

本次演示部署一个三个节点的es集群

为了方便，三个节点部署在一台机器上，以不同端口来区分

角色	ip地址	端口
node-1	10.2.2.10	9200
node-2	10.2.2.10	9201
node-3	10.2.2.10	9202

 

基础配置

修改/etc/security/limits.conf 配置文件，添加如下配置

* soft nofile 65536
* hard nofile 65536

* hard nofile 65536
* soft nofile 65536

* hard memlock unlimited
* soft memlock unlimited

修改/etc/sysctl.conf，添加如下配置

vm.max_map_count=262144

执行sysctl -p使配置生效

 

各个节点配置
