Started connect web server on http://localhost:9100

当我打开url：http://localhost:9100并单击[connect]按钮，但我无法连接到elasticsearch。任何人都可以帮助我吗？这是screenshot

在你elasticsearch.yml配置，你可能有以下设置：

http.port: 9201

这在日志中也可见：

[...] publish_address {127.0.0.1:9201}, bound_addresses {[fe80::1]:9201}, {[::1]:9201}, {127.0.0.1:9201} 
           ^
            | 
          your HTTP port

因此，在你elasticsearch-head接口，需要连接到localhost:9201而不是localhost:9200。

UPDATE

您还需要在您的elasticsearch.yml配置中添加http.cors.enabled: true并重新启动ES服务器

在我的电脑中，有两个实例，[YML-ES-节点-1]的端口是9200，[yml-es-node-2]的端口是9201.当我改为http：// localhost：9201时，也无法连接。 – Alex

yml-es-node-1是否正在运行？ – Val

是，正在运行 – Alex

elasticsearch头不能连接到以http elasticsearch：//本地主机：9200
