Elasticsearch报错:received plaintext http traffic on an https channel, closing connection Netty4HttpChannel。

现象,当启动Elasticsearch后,在浏览器输入地址 http://localhost:9200/

后,报错

received plaintext http traffic on an https channel, closing connection Netty4HttpChannel{localAddress=/[0:0:0:0:0:0:0:1]:9200

如图:

原因是Elasticsearch在Windows下开启了安全认证,虽然started成功,但访问http://localhost:9200/

失败。

解决方案:

找到config/目录下面的elasticsearch.yml配置文件,把安全认证开关从原先的true都改成false,实现免密登录访问即可,修改这两处都为false后:

即可解决问题,再次打开http://localhost:9200/

就正常显示内容了:
