Elasticsearch curl：（7）无法连接到主机 [英] Elasticsearch curl: (7) couldn't connect to host

问题描述

我尝试用mongodb进行弹性搜索。

我已经按照步骤从
http://satishgandham.com/2012/09/a-complete-guide-to-integrating- mongodb-with-elastic-search /

但是当我尝试通过

设置索引时

  curl -XPUT'http：// localhost：9200 / _river / mongodb / _meta'-d'
 {
type：mongodb，
mongodb：{
db：smmc-dart，
collection：smmc_collectionDetails
}，
index：{
 name：caseName，
type：string
} 
}'
  

我收到错误

  curl：（7）无法连接到主机
  

当我尝试 http：// localhost：9200 / 在我的浏览器上显示

  {
status：200，
name Nicholas Scratch，
version：{
number：1.1.0，
build_hash：2181e113dea80b4a9e31e58e9686658a2d46e363，
build_timestamp： -03-25T15：59：51Z，
build_snapshot：false，
lucene_version：4.7
}，
tagline搜索
} 
  

我也在终端试过了

  curl -XGET http://10.20.4.220:9200/ 
  

结果

  curl：（7）无法连接到主机
  
 
 
 
为什么会发生这种情况，以及如何修复它。
解决方案
在我的Mac OS X，我使用 127.0.0.1:9200 / 而不是 http： 9200 / 因为我有同样的问题。 
 
 
 
我认为当你使用命令终端替换localhost它的IPv6地址，我不知道curl支持。 
 
 
 
请检查并通知我。
 
I was trying out elastic search with mongodb.

I have followed steps from 
http://satishgandham.com/2012/09/a-complete-guide-to-integrating-mongodb-with-elastic-search/

But when I try to set index by
curl -XPUT 'http://localhost:9200/_river/mongodb/_meta' -d '
{
    "type": "mongodb",
    "mongodb": {
        "db": "smmc-dart",
        "collection": "smmc_collectionDetails"
    },
    "index": {
        "name": "caseName",
        "type": "string"
    }
}'
I'm getting error
curl: (7) couldn't connect to host
When I tried http://localhost:9200/ on my browser it shows
{
  "status" : 200,
  "name" : "Nicholas Scratch",
  "version" : {
    "number" : "1.1.0",
    "build_hash" : "2181e113dea80b4a9e31e58e9686658a2d46e363",
    "build_timestamp" : "2014-03-25T15:59:51Z",
    "build_snapshot" : false,
    "lucene_version" : "4.7"
  },
  "tagline" : "You Know, for Search"
}
I also tried this in terminal
curl -XGET http://10.20.4.220:9200/
It resulted
curl: (7) couldn't connect to host
Why is this happening and how to fix it.
解决方案
On my Mac OS X, I use  127.0.0.1:9200/ instead of http://localhost:9200/ cause I had the same problem. 

I think that when you use the command the terminal replaces the localhost by it's IPv6 address and I'm not sure that curl supports that. 

Please check and let me know.
