基于 Docker 构建 ElasticSearch


本文是一篇基于 Docker 构建 ElasticSearch 的入门级指南。

其实用 Docker 来构建真的很简单,这里就给大家贴我的实际配置和运行命令吧。

。。。

检查 ElasticSearch 状态

curl -XGET http://localhost:9200/_cluster/health?pretty

{
  "cluster_name" : "docker-cluster",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 1,
  "active_shards" : 1,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 1,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 50.0
}

增删改查

增加

curl -XPUT 'localhost:9200/twitter/tweet/1?pretty' -H 'Content-Type: application/json' -d'
{
    "user" : "kimchy",
    "post_date" : "2009-11-15T14:12:12",
    "message" : "trying out Elasticsearch"
}
'

执行结果:

{
  "_index" : "twitter",
  "_type" : "tweet",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

查询

curl -XGET 'http://localhost:9200/twitter/tweet/1'

执行结果:

{"_index":"twitter","_type":"tweet","_id":"1","_version":1,"found":true,"_source":
{
    "user" : "kimchy",
    "post_date" : "2009-11-15T14:12:12",
    "message" : "trying out Elasticsearch"
}
}
