Question

我已经使用.tar.gz作为wget的用户进行安装，并chown来作为xyz用户和xyzgrp组的用户来编辑elasticsearch文件夹。

我确实使用./bin/elasticsearch运行es，并与no errors正常运行。

然后我卷曲curl -X GET "localhost:9200"，它产生以下错误。但是，如果我以root curl的身份运行，则会吐出预期的输出。

作为xyz用户：

以root用户身份

：

{
  "name" : "wE3SaRO",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "YobA_1NiT_aHGlgQhAWdZA",
  "version" : {
    "number" : "6.4.2",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "04711c2",
    "build_date" : "2018-09-26T13:34:09.098244Z",
    "build_snapshot" : false,
    "lucene_version" : "7.4.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

还有一件事，我以xyz用户而不是以root用户的身份运行Elasticsearch

Elasticsearch：Curl -X GET“ localhost：9200”给出“网络错误（dns_unresolved_hostname）”
