1、Installation of Elasticsearch database
PS: Before that, you need to install the Java SE environment first!
Download elasticsearch-6.5.2, go to the /elasticsearch-6.5.2/bin directory, double-click to execute Open your browser and type inhttp://localhost:9200 The installation is successful if the following is displayed
Install head plugin for easy view management (also use kibana)
First install Nodejs (download at/en/）
re-downloadelasticsearch-head-masterThe package is extracted under /elasticsearch-6.5.2/ (link./s/1q3kokFhpuJ2Q3otPgu7ldg
Extract code: 1rpp
Modify the configuration file elasticsearch-6.5.2\config\ as follows:
Go to the elasticsearch-head-master directory and run npm install -g grunt-cli, then npm install to install the dependencies.
existelasticsearch-head-masterFind the file in the directory to modify the server listening address as follows:
Execute the grunt server command to start the head service.
access addresshttp://localhost:9100/ Access to the HEAD administration page
2, will write the json file into the ES database (py script as follows)
# -*- coding: UTF-8 -*-
from itertools import islice
import json , sys
from elasticsearch import Elasticsearch , helpers
import threading
_index = 'indextest' #Modify to index name
_type = 'string' #Modify to type name
es_url = 'http://192.168.116.1:9200/' #Modify to elasticsearch server
reload(sys)
('utf-8')
es = Elasticsearch(es_url)
(index=_index, ignore=400)
chunk_len = 10
num = 0
def bulk_es(chunk_data):
bulks=[]
try:
for i in xrange(chunk_len):
({
"_index": _index,
"_type": _type,
"_source": chunk_data[i]
})
(es, bulks)
except:
pass
with open([1]) as f:
while True:
lines = list(islice(f, chunk_len))
num =num +chunk_len
('\r' + 'num:'+'%d' % num)
()
bulk_es(lines)
if not lines:
print "\n"
print "task has finished"
break
