ES elasticsearch-8.17.0-windows-x86_64使用

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。

复制代码

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

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：
