1、环境初始化

最小化安装 Centos 7.x/Ubuntu x86_64 操作系统的虚拟机，vcpu 2，内存 4G 或更多，操作系统盘 50G，为保证效果特额外添加一块单独的数据磁盘大小为 50G 并格式化挂载到/data

1.1 设置主机名和磁盘挂载

节点信息

IP主机名角色系统版本10.10.100.110es-node1node1Ubuntu 18.04.310.10.100.111es-node2node2Ubuntu 18.04.310.10.100.112es-node3node3Ubuntu 18.04.3

2.1 jdk安装

elasticsearch 服务运行需要 java 环境

root@es-node1:~# tar xf jdk-8u301-linux-x64.tar.gz -C /usr/local/ root@es-node1:~# ln -sv /usr/local/jdk1.8.0_301 /usr/local/jdk root@es-node1:~# ln -sv /usr/local/jdk/bin/java /usr/bin/ root@es-node1:~# vim /etc/profile export JAVA_HOME=/usr/local/jdk export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin root@es-node2:~# source /etc/profile root@es-node1:~# java -version java version "1.8.0_301" Java(TM) SE Runtime Environment (build 1.8.0_301-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode) 2.2 下载 elasticsearch 并安装

开启跨域访问支持，然后重启 elasticsearch 服务

root@es-node1:~# vim /etc/elasticsearch/elasticsearch.yml #开启支持跨域访问 http.cors.enabled: true #指定允许访问范围 http.cors.allow-origin: "*" #重启 root@es-node1:~# systemctl restart elasticsearch 2.8 浏览器访问测试
