sudo yum install npm

sudo yum install -y bzip2

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

#将源码包下载后剪切到/bigdata目录，并改所属用户和组
sudo chown -R xiaoniu:xiaoniu /bigdata/elasticsearch-head

npm install


打开elasticsearch-head-master/Gruntfile.js，找到下面connect属性，新增hostname: '0.0.0.0',
        connect: {
                        server: {
                                options: {
                                        hostname: '0.0.0.0',
                                        port: 9100,
                                        base: '.',
                                        keepalive: true
                                }
                        }
                }

安装IK分词器
下载对应版本的插件
https://github.com/medcl/elasticsearch-analysis-ik/releases


首先下载es对应版本的ik分词器的zip包，上传到es服务器上，在es的安装目录下有一个plugins的目录，在这个目录下创建一个叫ik的目录
然后将解压好的内容，拷贝到ik目录
将ik目录拷贝到其他的es节点
重新启动所有的es


#创建索引名字叫news
curl -XPUT http://192.168.100.211:9200/news

#创建mapping（相当于数据中的schema信息，表名和字段名以及字段的类型）
curl -XPOST http://192.168.100.211:9200/news/fulltext/_mapping -d'
{
        "properties": {
            "content": {
