1、下载ES(elasticsearch 简称 ES 下载链接：https://www.elastic.co/downloads/elasticsearch)
ES 下载链接：https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.17.0-windows-x86_64.zip))，需要在修改ES配置，进入ES解压以后的文件下的config目录，找到elasticsearch.yml，打开后修改自己需要的配置
elasticsearch.yml配置如下，记事本打开保存时注意需要utf-8保存。
cluster.name: linjie
node.name: lj_node_1
network.host: 0.0.0.0
http.port: 9200
transport.port: 9300
#node.master: true
#node.data: true
#discovery.zen.ping.unicast.hosts: ["0.0.0.0:9300", "0.0.0.0:9301"]
#discovery.zen.minimum_master_nodes: 1
#node.ingest: true
bootstrap.memory_lock: false
#node.max_local_storage_nodes: 2
path.data: D:\Temp\1\elasticsearch-8.17.0-windows-x86_64\data
path.logs: D:\Temp\1\elasticsearch-8.17.0-windows-x86_64\logs
http.cors.enabled: true
http.cors.allow-origin: /.*/
# Enable security features

xpack.security.enrollment.enabled: true
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:

keystore.path: certs/http.p12
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:

cluster.initial_master_nodes: ["lj_node_1"]
2、安装时遇到的问题：
浏览器无法访问127.0.0.1:9200
127.0.0.1:9200无法访问：elasticsearch8.3安装配置（window）_elasticsearch-8.13.2 windows-CSDN博客
访问后可能提示 localhost 未发送任何数据。 ERR_EMPTY_RESPONSE
查看控制台报错：
received plaintext htp traffic on an https channel, closing connection Netty4HttpChannel
此报错原因在于是因为开启了 ssl 认证。解决
查看configelasticsearch.yml
启动后增添了一些默认配置信息，需要将xpack.security.enabled，xpack.security.enrollment.enabled 修改为false，关闭ssl认证
用户密码未知的问题
Elasticsearch8 安装完成后，用 elasticsearch-head连接，提示需要用户名密码。
Elasticsearch8默认用户名为elastic， 密码可以使用以下命令进行重置（bin目录下）cmd输入：elasticsearch-reset-password -u elastic ，再选择y,然后密码会显示出来。
如：elastic，PE2BS78Sut28xUBrLIS1
在网址里面输入：https://127.0.0.1:9200/，界面如下：
