  • 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。

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

    /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。

    [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。

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

    我们从启动就看的出来,IK分词器安装成功。
