版本说明

根据ik官网提示,elasticsearch2.4.0需要使用elasticsearch-analysis-ik-1.10.0版本

前提条件

首先,需要有一个es服务器.

其次,需要一个maven环境(由于ik不再支持install安装,只能通过源码安装)

提示:如果不想搭建maven环境,可以使用我已经打包好的elasticsearch-analysis-ik-1.10.0.zip

安装步骤

1.下载源码

https://codeload.github.com/medcl/elasticsearch-analysis-ik/zip/v1.10.0

2.插件打包

unzip elasticsearch-analysis-ik-1.10.0.zip
cd elasticsearch-analysis-ik-1.10.0
mvn package#出现下面内容说明编译成功

3.安装插件

将zip包解压到ES_HOME/plugins/ik目录下(ik目录需要自己创建)

重启es服务器即可.

注: 由于新版本ik插件不需要配置elasticsearch.yml文件.重启后,在日志中看到ik-analyzer表示ik分词器安装成功
