Elasticsearch Introduction, stand-alone installation, Python write Elasticsearch API

Elasticsearch is an open source, distributed, restful search engine built on Lucene. Designed for cloud computing, to achieve real-time search, stable, reliable, fast, easy to install and use. Supports the use of JSON for data indexing over HTTP.

stand-alone Environment

Stand-alone version of the Elasticsearch operation is very simple, Linux directly under the Bin/elasticsearch run, Windows run Bin/elasticsearch.bat. If it is in the LAN running Elasticsearch cluster is also very simple, as long as the cluster.name set consistent, and the machine under the same network segment, the boot of the ES will automatically find each other, composed of cluster installation head plug-ins:

Elasticsearch-head is a elasticsearch cluster management tool.

1.elasticsearch/bin/plugin-install Aconex/elasticsearch-head

2. Running ES

3. Open http://localhost:9200/_plugin/head/

Install Elasticsearch-bigdesk:

Bigdesk is a elasticsearch cluster monitoring tool that allows you to view the various states of the ES cluster

1.bin/plugin-install Lukas-vlcek/bigdesk

2. Running ES

3. Open http://localhost:9200/_plugin/bigdesk/

I tried to write a piece of code in Python that put the data in Elasticsearch.

#-*-Coding:utf-8-*-

From Elasticsearch import Elasticsearch

From Elasticsearch Import Helpers

From datetime import datetime

Import Sys

Sys.path.append ("..")

Import Uuid,time

From Core.logger import Mlogger

#sys. Path.append ("..")

Class Elasticsearchadapter (Nosqlbase):

# "" "Elasticsearch Interface Class" "

def __init__ (self,pconf):

Super (Elasticsearchadapter, self). __init__ ()

self.es = Elasticsearch (hosts= "10.11.115.61")

def save (Self,data):

idx = ' Default_index '

Try

Typ = ' Default_type '

Self.es.index (Index=idx, Doc_type=typ, body={"Data":d ata, "Datastore_timestamp": Time.time ()})

I am also the first contact with ES if there is any problem, please feel free to advise
