前提**[Elasticsearch之中文分词器插件es-ik的自定义词库][Elasticsearch_es-ik]**

先声明，热更新词库，需要用到，web项目和Tomcat。不会的，请移步

# [Eclipse下Maven新建项目、自动打依赖jar包（包含普通项目和Web项目）][Eclipse_Maven_jar_Web] #

# [Tomcat \*的安装和运行（绿色版和安装版都适用）][Tomcat] #

# [Tomcat的配置文件详解][Tomcat 1] #

1： 部署 http 服务  
在这使用 tomcat7 作为 web 容器， 先下载一个 tomcat7， 然后上传到某一台服务器上(192.168.80.10)。  
再执行以下命令  
　　tar -zxvf apache-tomcat-7.0.73.tar.gz  
　　cd apache-tomcat-7.0.73/webapp/ROOT  
vi hot.dic  
　　测试

在这里，我是为了避免跟我的hadoop和spark集群里的端口冲突，将默认的tomcat8080端口，改为8081端口了。

# [在CentOS下安装tomcat并配置环境变量（改默认端口8080为8081）][CentOS_tomcat_8080_8081] #

如果，是3台tomcat集群的话，则对应，比如我的192.168.80.10位8081端口，192.168.80.11位8082端口，192.168.80.12位8083端口

验证一下这个文件是否可以正常访问

http://192.168.80.10:8081/zhoulshot.dic

2： 修改 ik 插件的配置文件  
cd elasticsearch-2.4.3/plugins/ik/config  
vi IKAnalyzer.cfg.xml  
修改 key=remote\_ext\_dict 的 entry 中的内容  
<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">  
　　<properties>  
　　<comment>IK Analyzer 扩展配置</comment>  
　　  
　　<entry key="ext\_dict">custom/mydict.dic;custom/single\_word\_low\_freq.dic;custom/zhouls.dic</entry>  
　　  
　　<entry key="ext\_stopwords">custom/ext\_stopword.dic</entry>  
　　  
　　<entry key="remote\_ext\_dict">http://192.168.80.10:8081/zhoulshot.dic</entry>  
　　  
　　  
</properties>

**注意：（1）**默认是words\_location，我这里改为我自己的了。http://192.168.80.10:8081/zhoulshot.dic   （自定义词库）

**（2）**默认是custom/mydict.dic;custom/single\_word\_low\_freq.dic，我这里改为我自己的了。    （自定义热更新词库）   custom/mydict.dic;custom/single\_word\_low\_freq.dic;custom/zhouls.dic

3： 验证  
　　重启 es， 会看到如下日志信息， 说明远程的词典加载成功了。

执行下面命令查看分词效果  
　　curl 'http://192.168.80.10:9200/zhouls/\_analyze?analyzer=ik\_max\_word&pretty=true' -d '\{"text":"桂林山水"\}'  
正常情况下桂林山水会分为多个词语， 但是我们希望 es 把\[桂林山水\]作为一个完整的词， 又不希望重启 es。  
这样就需要修改前面的 zhoulshot.dic 文件， 增加一个词语\[桂林山水\]

vi hot.dic  
　　桂林山水  
文件保存之后， 查看 es 的日志会看到如下日志信息

再执行下面命令查看分词效果  
　　curl 'http://192.168.80.10:9200/zhouls/\_analyze?analyzer=ik\_max\_word&pretty=true' -d '\{"text":"桂林山水"\}'  
到这为止， 可以实现动态添加自定义词库实现词库热更新。  
==============================================================================  
　　注意： 默认情况下， 最多一分钟之内就可以识别到新增的词语。

查看 es-ik 插件的源码可以发现

**1： 部署 http 服务**

第一步：下载tomcat压缩包

第五步：重命名tomcat安装目录

drwxr-xr-x. 10 hadoop hadoop 4096 Nov 1 23:39 zookeeper-3.4.6  
\[hadoop@HadoopMaster app\]$

第六步：进入tomcat安装目录，并初步认识下

![855959-20170225112238976-399801936.png][]

\[hadoop@HadoopMaster app\]$ cd tomcat-7.0.73/

drwxr-xr-x. 2 hadoop hadoop 4096 Nov 8 05:27 work  
\[hadoop@HadoopMaster tomcat-7.0.73\]$

在这里，需要，先事先好，在linux下安装好tomcat。并配置好环境变量。不会的，请移步

# [在CentOS下安装tomcat并配置环境变量][CentOS_tomcat_8080_8081] #

[ ][CentOS_tomcat_8080_8081]

第七步：进入webapps/ROOT目录下

![855959-20170225112458085-451437819.png][]

\[hadoop@HadoopMaster tomcat-7.0.73\]$ cd webapps/

第八步：新建，自定义的热更新词库。如，我这里，是，zhoulshot.dic

\-rw-rw-r--. 1 hadoop hadoop 55 Feb 25 19:44 zhoulshot.dic  
\[hadoop@HadoopMaster ROOT\]$

第九步：验证一下这个zhoulshot热更新词文件是否可以正常访问

**3： 验证**  
　　重启 es， 会看到如下日志信息， 说明远程的词典加载成功了。

我这里，为了更好地看出效果，在es的安装目录下，bin/elasticsearch这种方式来启动。

正常情况下桂林不雾霾会分为多个词语， 但是我们希望 es 把\[桂林不雾霾\]作为一个完整的词， 又不希望重启 es。  
　　这样就需要修改前面的 zhoulshot.dic 文件， 增加一个词语\[桂林不雾霾\]  
vim zhoulshot.dic
