安装 Elasticserach:
下载最新的elasticsearch:官网地址: https://www.elastic.co/downloads/elasticsearch
解压缩之后,把 elasticsearch-<version>/bin 路径放到 bash_profile 里
-
运行
elasticsearch
-
用命令行测试
curl 'http://localhost:9200/'
应给得到类似下面的响应:
{ "name" : "VJ6rpak", "cluster_name" : "elasticsearch", "cluster_uuid" : "enuYtqaGTaqoSYwErlyZBw", "version" : { "number" : "6.2.4", "build_hash" : "ccec39f", "build_date" : "2018-04-12T20:37:28.497551Z", "build_snapshot" : false, "lucene_version" : "7.2.1", "minimum_wire_compatibility_version" : "5.6.0", "minimum_index_compatibility_version" : "5.0.0" }, "tagline" : "You Know, for Search" }

安装图形界面kibana
解压缩之后,把 kibana-<version>/bin 路径放到 bash_profile 里
中文版教程中还有安装 sense 的步骤,但 Kibana 从 5.0.1 版本开始就已经自带了调试工具,可以在 kibana 左侧工具栏 DevTools 中找到。
-
启动kibana
kibana
用浏览器访问图形界面:http://localhost:5601
-
Hello World
-
在 DevTools 查询集群中文档总数量
GET /_count { "query":{ "match_all":{} } }
-
返回:
{ "count": 1, "_shards": { "total": 5, "successful": 5, "skipped": 0, "failed": 0 } }
-
-
Python 插件 elasticsearch
-
安装elasticsearch
pip3 install elasticsearch
-
hello world
from elasticsearch import Elasticsearch import pprint es = Elasticsearch() doc = { "query":{ "match_all":{} } } res = es.search(body=doc) pprint.pprint(res)
-
应该得到下面的结果:
{'_shards': {'failed': 0, 'skipped': 0, 'successful': 5, 'total': 5}, 'hits': {'hits': [{'_id': '1', '_index': 'test-index', '_score': 1.0, '_source': {'author': 'kimchy', 'text': 'Elasticsearch: cool. bonsai cool.', 'timestamp': '2018-05-10T10:24:58.396432'}, '_type': 'tweet'}], 'max_score': 1.0, 'total': 1}, 'timed_out': False, 'took': 1}
