启动后elasticsearch.bat，访问9200失败，提示连接被重置

如果启动后，访问9200失败，提示连接被重置，就在ElasticSearch下的config目录中的elasticsearch.yml下滑到最低端，将xpack.security.enabled: false修改为false以及 xpack.security.http.ssl: enabled: false修改为false

Enable security features

xpack.security.enabled: false

2
Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
enabled: false
keystore.path: certs/http.p12

同样的ElasticSearch下的config目录中的elasticsearch.yml文件下的Network 中的network.host: x.x.x.x修改为#network.host: 0.0.0.0（也可以是本机ip地址或者127.0.0.1，0.0.0.0表示谁都可以访问）

---------------------------------- Network -----------------------------------

By default Elasticsearch is only accessible on localhost. Set a different

address here to expose this node on the network:

network.host: 0.0.0.0

最后：保存退出并重启Elasticsearch，双击ElasticSearch下的bin目录中的elasticsearch.bat启动
