elasticsearch安装ik分词器（极速版）

简介：
下面讲有我已经打包并且编辑过的zip包，你可以在下面下载即可。

1、下载zip包。
elasticsearch-analysis-ik-1.8.0.jar
下面有附件链接【ik-安装包.zip】，下载即可。（内有做好的elasticsearch-analysis-ik-1.8.0.jar）

2、上传zip包。
下载ik.zip文件后解压缩，如下图。

修改plugin-descriptor.properties文件，将elasticsearch.version=2.2.0改成自己的elasticsearch版本（通过访问localhost:9200查看版本号）
#把这个版本号改成你对应的版本即可，如你的版本是2.2.0，就改成2.2.0
elasticsearch.version=2.2.0

修改好后，打成zip包上传至Linux系统elasticsearch-2.2.0/plugins目录下，使用unzip ik.zip解压
此处注意目录结构必须是这样，如下图：

3、启动测试
呃，我们发现报错了。
[elasticsearch@iZ25x3wjytdZ elasticsearch-2.0.0]$ ./bin/elasticsearch

一看我们就知道，他去找plugins/ik.zip 下的配置文件对吧。解决方案是把这个ZIP包删除即可。删除后再次启动。

我们从启动就看的出来，IK分词器安装成功。
