mac ElasticSearch + + node + installation example of a head ~

1. Download ElasticSearch

Net official download link: https://www.elastic.co/cn/downloads/past-releases (go may be slower, Network good situation will be better)

I was under the version is 7.0.3, and 5.6.8 have compared the windows very different, including some of the attributes of what methods, so be careful! weight! selected! Optional!

2. Run ElasticSearch

After it is finished, unzip to where you want to unpack, open the bin

Click on the first one, will show a bunch of boot log,

Show started on ok,

In the browser address bar enter http: // localhost: 9200

This explains ElasticSearch display to successfully install it, turn off the startup of elasticsearch Terminal Services Mac: Ctrl + c.

3. Install node

Used here is homebrew

brew install node

Wait until the installation is complete, there should not be any hole, if the download fails you can turn off the terminal repeated several times (the network itself), with a time of npm install homebrew node is a default component will be installed, and comes with a Bahrain nodejs npm.

Then, enter homebrew

git clone git://github.com/mobz/elasticsearch-head.git

The cloned into local mirroring, after the end of input into the catalog

elasticsearch- cd head 
npm install 
npm install -g Grunt-cil // If unsuccessful before

After implementation, modification elasticsearch profile: elasticsearch.yml, add the following two commands:

http.cors.enable:true
http.cors.allow-origin:"*"

This step is to allow access across elasticsearch.

After the completion of re-entering the head, enter at the command prompt:

grunt server

This display can be at http: visit friends 9100: // loaclhost

        TransportClient client = new PreBuiltTransportClient(Settings.EMPTY).
        addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
        //2、创建文档内容
        XContentBuilder builder = XContentFactory.jsonBuilder()
        .startObject()
        .field("id",1) .field("title","elasticsearch是一个基于lucene的搜索服务") .field("content","ElasticSearch是一个基于Lucene的搜索服务器。" +

Run, in the open http: // localhost: 9100,

Such is the success of you, if you still do not show the words:

1. Check the first jar package and import their own elasticsearch versions are the same,

2. Look maven dependencies there is no full
