docker环境搭建elasticsearch

序

本文主要讲如何使用使用docker搭建elasticsearch。

下载镜像

这里利用hangxin1940搭好的镜像，不过是es的1.4.2版本。

docker pull hangxin1940/docker-elasticsearch-cn:v1.6.0

启动容器

docker run -d -p 9200:9200 -p 9300:9300 --name es hangxin1940/docker-elasticsearch-cn:v1.6.0

查看es(这里的ip是docker的default machine的ip)

访问http://192.168.99.100:9200/

{
status: 200,
name: "node1",
cluster_name: "cn-out-of-box",
version: {
number: "1.6.0",
build_hash: "cdd3ac4dde4f69524ec0a14de3828cb95bbb86d0",
build_timestamp: "2015-06-09T13:36:34Z",
build_snapshot: false,
lucene_version: "4.10.4"
},
tagline: "You Know, for Search"
}

查看集群状态

http://192.168.99.100:9200/_plugin/head/

也可以用命令行

curl -XGET http://192.168.99.100:9200/_cluster/health?pretty

返回

{
  "cluster_name" : "cn-out-of-box",
  "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,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0
}

这里目前只是单节点的，后续弄成集群看看。

增删改查

增加

curl -XPUT 'http://192.168.99.100:9200/twitter/tweet/1' -d '{
    "user" : "kimchy",
    "post_date" : "2009-11-15T14:12:12",
    "message" : "trying out Elastic Search"
}'

返回

{"_index":"twitter","_type":"tweet","_id":"1","_version":1,"created":true}%

查询

curl -XGET 'http://192.168.99.100:9200/twitter/tweet/1'

返回

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

高级查询:选择字段

curl -XGET 'http://192.168.99.100:9200/twitter/tweet/1?fields=message,user&pretty=true'

返回

{
  "_index" : "twitter",
  "_type" : "tweet",
  "_id" : "1",
  "_version" : 1,
  "found" : true,
  "fields" : {
    "message" : [ "trying out Elastic Search" ],
    "user" : [ "kimchy" ]
  }
}

高级查询：选择格式

curl -XGET 'http://192.168.99.100:9200/twitter/tweet/1?fields=message,user&format=yaml'

返回

---
_index: "twitter"
_type: "tweet"
_id: "1"
_version: 1
found: true
fields:
  message:
  - "trying out Elastic Search"
  user:
  - "kimchy"

更新

curl -X PUT http://192.168.99.100:9200/twitter/tweet/1 -d '{"message": "hello world", "user": "patterncat"}'

返回

{"_index":"twitter","_type":"tweet","_id":"1","_version":2,"created":false}%

这个是覆盖更新，不是局部更新：

 ~  curl -XGET 'http://192.168.99.100:9200/twitter/tweet/1'
{"_index":"twitter","_type":"tweet","_id":"1","_version":2,"found":true,"_source":{"message": "hello world", "user": "patterncat"}}%

删除

curl -XDELETE 'http://192.168.99.100:9200/twitter/tweet/1'

返回

{"found":true,"_index":"twitter","_type":"tweet","_id":"1","_version":3}%
