在https通道上接收到明文http流量，关闭连接Netty4HttpChannel{localAddress=/127.0.0.1:9200，远程地址=/127.0.0.1:494

Question

我试图在本地机器上运行elasticsearch集群，我已经下载了java、elasticsearch和Kibana。在elasticsearch目录中，我执行了bin/elasticsearch，然后终端上的一个日志开始显示，并表示状态是绿色的，但是当我访问http://127.0.0.1:9300/时，它在下面的says不能连接是终端日志的一部分，我认为这是一个错误：

Answer 1

TLDR；

您正在寻找的图形界面是Kibana。您正在尝试访问Elasticsearch的transport layer port。

去理解

Elasticsearch公开2 默认端口

• 9200，即http api层
• 9300，即传输层

但是，这些端口的none将提供html内容。Elasticsearch只公开API，它是后端服务器。

Elasticsearch的接口是Kibana。您需要安装和安装Kibana来连接Elasticsearch的API层。

对于非常基本的设置，只需在kibana.yml文件中提供

elasticsearch.hosts: <address of the elastic server + api port>
