Elasticsearch教程（三），IK分词器安装 （极速版）

如果只想快速安装 IK  ，本教程管用。下面看经过。

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。
• 当前讲解的 IK分词器  包的 version 为1.8。

一、下载zip包。

    下面有附件链接【ik-安装包.zip】，下载即可。

二、上传zip包。

    下载后解压缩，如下图。

    

打开修改修改好后打成zip包。

1. # 'elasticsearch.version' version of elasticsearch compiled against
2. # You will have to release a new version of the plugin for each new
3. # elasticsearch release. This version is checked when the plugin
4. # is loaded so Elasticsearch will refuse to start in the presence of
5. # plugins with the incorrect elasticsearch.version.
6. #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
7. elasticsearch.version=2.0.0

1. /elasticsearch-2.0.0/plugins

在plugins/目录下上传，并且解压缩。此处注意目录结构必须是这样，如下图：

三、启动测试

    呃，我们发现报错了。

1. [elasticsearch@iZ25x3wjytdZ elasticsearch-2.0.0]$ ./bin/elasticsearch
2. [2016-03-01 10:32:02,958][INFO ][node ] [Landslide] version[2.0.0], pid[11109], build[de54438/2015-10-22T08:09:48Z]

20. at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:270)
21. at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)

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。

1. [elasticsearch@iZ25x3wjytdZ elasticsearch-2.0.0]$ ./bin/elasticsearch

我们从启动就看的出来，IK分词器安装成功。
