elasticsearch - Elasticsearch GET / 返回 HTML 错误而不是 JSON 响应

问题描述

我最近在 RHEL 上安装了 Elasticsearch，并在配置文件中设置了节点名称。后来，我使用sudo systemctl start elasticsearch.service该服务似乎正在按照状态命令运行该服务启动该服务

 sudo systemctl status elasticsearch.service
● elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2020-11-25 14:59:13 CET; 2h 37min ago

Nov 25 14:59:13 hdm18 systemd[1]: Started Elasticsearch.

但是 GET 的输出是返回一个 HTML 页面而不是 JSON 消息

curl -X GET "localhost:9200/?pretty"
<!-- IE friendly error message walkround.        
     if error message from server is less than   
     512 bytes IE v5+ will use its own error     
     message instead of the one returned by      
     server.                                 --> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
  <head>
    <meta
    enter code here

知道我在做什么错吗？

解决方案

我相信你从这个官方链接复制了你的命令，但是如果你复制 curl 命令，它会像curl -X GET "localhost:9200/?pretty".

以上将在正确的输出下方打印。
