Elasticsearch这里安装在了Windows下

安装Elasticsearch，我这里选择的是最新版本（8.3.3）

下载地址： https://www.elastic.co/cn/downloads/elasticsearch

下载完之后解压文件夹

进入bin

双击执行
执行完成后会显示以下内容

-> Elasticsearch security features have been automatically configured!
-> Authentication is enabled and cluster connections are encrypted.

->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  01aVmPEg7*bWmgGaXnv0

->  HTTP CA certificate SHA-256 fingerprint:
  1ae7d35f3165a808fe6b55fc6090ff938dadc55ac86b3330548ef6b9a896f5b8

->  Configure Kibana to use this cluster:
* Run Kibana and click the configuration link in the terminal when Kibana starts.
* Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):

->  Configure other nodes to join this cluster:
* On this node:
  - Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
  - Uncomment the transport.host setting at the end of config/elasticsearch.yml.
  - Restart Elasticsearch.
* On other nodes:
  - Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.

其中，需要注意两处

Elastic为登录账号，01aVmPEg7*bWmgGaXnv0为登录密码，密码是随机生成，不可直接复制本文中的。
安装完成后，进入config文件夹

打开elasticsearch.yml文件


访问访问localhost:9200，出现下图，则成功

JEECGBoot的配置

因为在application-dev.yml的配置中，没有配置登录的账户和密码，所以这里我们选择elasticsearch为免密登录

完成以上配置，直接启动项目即可
