elasticsearch的默认用户和密码是什么？

Question

我有installed Elastic with Docker：

docker run -p 9200:9200 \ 
      -p 9300:9300 \ 
      -e "discovery.type=single-node" \ 
      docker.elastic.co/elasticsearch/elasticsearch:5.6.2 

但curl localhost:9200失败，身份验证错误：

{ 
    "error": { 
    "root_cause": [ 
     { 
     "type": "security_exception", 
     "reason": "missing authentication token for REST request [/]", 
     "header": { 
      "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\"" 
     } 
     } 
    ], 
    "type": "security_exception", 
    "reason": "missing authentication token for REST request [/]", 
    "header": { 
     "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\"" 
    } 
    }, 
    "status": 401 
} 

什么是Elasticsearch默认的用户名/密码组合？

Answer 1

Defaults are：

user: elastic 
password: changeme 

所以：

$ curl -u elastic:changeme localhost:9200 
{ 
    "name" : "5aEHJ-Y", 
    "cluster_name" : "docker-cluster", 
    "cluster_uuid" : "3FmaYN7rS56oBTqWOyxmKA", 
    "version" : { 
    "number" : "5.6.2", 
    "build_hash" : "57e20f3", 
    "build_date" : "2017-09-23T13:16:45.703Z", 
    "build_snapshot" : false, 
    "lucene_version" : "6.6.1" 
    }, 
    "tagline" : "You Know, for Search" 
}
