Elasticsearch啟動(dòng)

# 進(jìn)入到elasticsearch的bin目錄 cd /.../.../elasticsearch-x.x.x/bin # 啟動(dòng)elasticsearch ./elasticsearch

可以再開啟另外一個(gè)終端,輸入一下命令,測(cè)試是否啟動(dòng)成功

curl http://localhost:9200/ {"name" : "F37KLEk","cluster_name" : "elasticsearch","cluster_uuid" : "ZP1f4uWzRwyRCp0UElz9KA","version" : {"number" : "6.3.1","build_flavor" : "default","build_type" : "tar","build_hash" : "eb782d0","build_date" : "2018-06-29T21:59:26.107521Z","build_snapshot" : false,"lucene_version" : "7.3.1","minimum_wire_compatibility_version" : "5.6.0","minimum_index_compatibility_version" : "5.0.0"},"tagline" : "You Know, for Search" }

在Python中操作Elasticsearch
安裝Elasticsearch模塊

pip install elasticsearch from elasticsearch import Elasticsearch# 默認(rèn)host為localhost,port為9200.但也可以指定host與port es = Elasticsearch()# 添加或更新數(shù)據(jù),index，doc_type名稱可以自定義，id可以根據(jù)需求賦值,body為內(nèi)容 es.index(index="my_index",doc_type="test_type",id=1,body={"name":"python","addr":"深圳"})# 或者:ignore=409忽略文檔已存在異常 es.create(index="my_index",doc_type="test_type",id=1,ignore=409,body={"name":"python","addr":"深圳"})

查詢數(shù)據(jù)

from elasticsearch import Elasticsearches = Elasticsearch()# 獲取索引為my_index,文檔類型為test_type的所有數(shù)據(jù),result為一個(gè)字典類型 result = es.search(index="my_index",doc_type="test_type")# 或者這樣寫:搜索id=1的文檔 result = es.get(index="my_index",doc_type="test_type",id=1)# 打印所有數(shù)據(jù) for item in result["hits"]["hits"]:print(item["_source"]) form elasticsearch import Elasticsearches = Elasticsearch()# 刪除id=1的數(shù)據(jù) result = es.delete(index="my_index",doc_type="test_type",id=1)
