Elasticsearch安装ik分词器（二）

一、先测试是否安装了ik分词器

先测试是否安装了ik分词器：
http://10.1.2.206:9200/_analyze?analyzer=standard&pretty=true&text=中华人民共和国

没有安装则如下：
tokens  
0   
token   "中"
start_offset    0
end_offset  1
type    "<IDEOGRAPHIC>"
position    1
1   
token   "华"
start_offset    1
end_offset  2
type    "<IDEOGRAPHIC>"
position    2
2   
token   "人"
start_offset    2
end_offset  3
type    "<IDEOGRAPHIC>"
position    3
3   
token   "民"
start_offset    3
end_offset  4
type    "<IDEOGRAPHIC>"
position    4
4   
token   "共"
start_offset    4
end_offset  5
type    "<IDEOGRAPHIC>"
position    5
5   
token   "和"
start_offset    5
end_offset  6
type    "<IDEOGRAPHIC>"
position    6
6   
token   "国"
start_offset    6
end_offset  7
type    "<IDEOGRAPHIC>"
position    7


注意：2.0一下版本需要加index

二、安装

[root@bogon es]# git clone https://github.com/medcl/elasticsearch-analysis-ik
[root@bogon es]# cd elasticsearch-analysis-ik
[root@bogon es]# git tag --查看版本号
[root@bogon es]# git checkout tags/{version}
[root@bogon es]# mvn clean
[root@bogon es]# mvn compile
[root@bogon es]# mvn package
1.拷贝和解压release下的文件: /elasticsearch-analysis-ik/target/releases/elasticsearch-analysis-ik-1.4.1-jar-with-dependencies.jar 到你的 elasticsearch 插件目录, 如: plugins/ik 

2.拷贝config文件：/elasticsearch-analysis-ik/config/elasticsearch.yml中的内容拷贝到es的config下elasticsearch.yml中（最下方）、其余的（ik文件夹和logging.yml）也拷贝到es的config下
