Because the head is a Node.js project. So, if there is no need to install nodejs installed Node.js, to Node.js v4.4.3 LTS (Long Term Support) version, for example.
- 32 Download installation package: https://nodejs.org/dist/v4.4.3/node-v4.4.3-x86.msi
- 64 Download installation package: https://nodejs.org/dist/v4.4.3/node-v4.4.3-x64.msi
Detect environment variable is configured in Node.js, open a command line, type the command "path" after to see:
Enter the command "node --version" to view node version:

Because running head needs the grunt command, so you need to install grunt. Node.js into the directory, execute the command npm install -g grunt-cli, install the grunt-bit global commands.
Head into the home directory to perform the installation npm install grunt, grunt -version executed after the installation is complete to see if the installation is successful, it will display the version number installed.
4. Head Configuration
1) Access config installation directory under the directory, the file elasticsearch.yml modify, add the following code to the end of file
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
2) network.host: 192.168.0.1 and Notes to network.host: 0.0.0.0; remove cluster.name node.name http.port, annotations (i.e. # removed)
. 3) Double elasticsearch.bat restart ES
. 4 .) to find the folder head downloaded file Gruntfile.js, together with the corresponding position in the hostname: '*'
5) head starts:. enter the command execution head npm the install folder after installation or execution grunt server npm run start running head plug, if unsuccessful re-install grunt. Success follows:
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:9100
6) under the browser to http:. // localhost: 9100 /
Import data exemplary 5.postman
1) Create an index and mapping
--put请求 localhost:9200/local_library索引名
mappings:
{
"mappings":{
"book":{
"properties":{
"book_id":{
"type":"long",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"book_code":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"book_name":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"book_price":{
"type":"integer",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"book_author":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"book_desc":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
}
}
}
}
}
If you want to try a new postman data, you can add the following code
-- post请求 localhost:9200/local_library/book/1 索引/对象/id
{
"Book_id":. 1,
"book_code": "A0001",
"BOOK_NAME": "Emperor Qin",
"book_price": 180 [,
"BOOK_AUTHOR": "Tang three little",
"book_desc": "best looking fantasy novel ! "
}
The results can be viewed in the head tag data view, may be viewed by the code postman operates as follows:
-- post请求 localhost:9200/local_library/_search?pretty
{
"query": {
"match": {
"id": "1"
}
}
}
