solr3.5 + IKAnalyzer3.2.8 + Tomcat5.5 搭建配置(一)

Solr是一个全文检索服务器,基于Lucene3.5开发的,我们可以在solr的基础上进行定制化的开发。
要进行solr开发首先得搭建一个solr服务器。
1、首先我们下载solr3.5和lucene3.5,分别在:
 Solr:http://apache.etoak.com//lucene/solr/3.5.0
 Lucene: http://apache.etoak.com//lucene/java/3.5.0/
2、将apache-solr-3.5.0\apache-solr-3.5.0\dist\apache-solr-3.5.0.war复制到apache-tomcat-6.0.29\webapps目录下面,
改名为solr.war,并启动tomcat,浏览http://localhost:8080/solr/,没有出错表示已经部署没有问题,停tomcat。

3、apache-solr-3.5.0\apache-solr-3.5.0\example\multicore复制到apache-tomcat\webapps\solr\conf下面

4、配置war运行的context上下文,在apache-tomcat\conf\Catalina\localhost创建文件solr.xml文件,此文件内容为:

    <?xml version="1.0" encoding="UTF-8"?>
    <Context docBase="${catalina.home}/webapps/solr.war" debug="0" crossContext="true" > 
            <Environment name="solr/home" type="java.lang.String"
  value="${catalina.home}/webapps/solr/conf/multicore" override="true" /> 
    </Context>

5、这个配置也可以写死到Tomcat 5.5\conf\web.xml里去,找到
<!-- solr-->
 <env-entry>
       <env-entry-name>solr/home</env-entry-name>
       <env-entry-value>${catalina.home}/webapps/solr/conf/multicore</env-entry-value>
       <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>

6、启动tomcat,访问http://localhost:8080/solr。出现两个链接Admin core0和Admin core1则搭建成功

7、配置上solr默认安装时一个Solr 的主目录
 将上述Tomcat 5.5\conf\web.xml中的配置 <env-entry-value>${catalina.home}/webapps/solr/conf/multicore</env-entry-value>
 改为 <env-entry-value>${catalina.home}/webapps/solr/conf/solr</env-entry-value>
 将apache-solr-3.5.0\apache-solr-3.5.0\example\下的solr文件夹内容拷贝在/webapps/solr/conf/下。
8、配置solrconfig.xml文件找到
  <!-- The solr.velocity.enabled flag is used by Solr's test cases so that this response writer is not
         loaded (causing an error if contrib/velocity has not been built fully) -->
    <queryResponseWriter name="velocity" class="solr.VelocityResponseWriter" enable="${solr.velocity.enabled:true}"/>
    看注释也知道这是一个测试项目中的一个response writer,没有加载,因为没有built fully,所以先注释掉。要不然会起不来的。
    还要注意的是下面
     <lib dir="../../contrib/extraction/lib" />
  <lib dir="../../contrib/clustering/lib/" />
  <lib dir="../../contrib/velocity/lib" />

  <!-- When a regex is specified in addition to a directory, only the
       files in that directory which completely match the regex
       (anchored on both ends) will be included.
    -->
  <lib dir="../../dist/" regex="apache-solr-cell-\d.*\.jar" />
  <lib dir="../../dist/" regex="apache-solr-clustering-\d.*\.jar" />
  <lib dir="../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
  <lib dir="../../dist/" regex="apache-solr-langid-\d.*\.jar" />
  <lib dir="../../dist/" regex="apache-solr-velocity-\d.*\.jar" />

  <!-- If a dir option (with or without a regex) is used and nothing
       is found that matches, it will be ignored
    -->
  <lib dir="../../contrib/clustering/lib/" />
  注意这个lib的加载路径一定要设置好,先从解压的工程中找出这些路径下的lib放到webapps的solr里面的一个路径中,并配置上
  我配置的路径是:
    <lib dir="solr/WEB-INF/lib/contrib/extraction/lib" />
  <lib dir="solr/WEB-INF/lib/contrib/clustering/lib/" />
  <lib dir="solr/WEB-INF/lib/contrib/velocity/lib" />

  <!-- When a regex is specified in addition to a directory, only the
       files in that directory which completely match the regex
       (anchored on both ends) will be included.
    -->
  <lib dir="solr/WEB-INF/lib/dist/" regex="apache-solr-cell-\d.*\.jar" />
  <lib dir="solr/WEB-INF/lib/dist/" regex="apache-solr-clustering-\d.*\.jar" />
  <lib dir="solr/WEB-INF/lib/dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
  <lib dir="solr/WEB-INF/lib/dist/" regex="apache-solr-langid-\d.*\.jar" />
  <lib dir="solr/WEB-INF/lib/dist/" regex="apache-solr-velocity-\d.*\.jar" />

  <!-- If a dir option (with or without a regex) is used and nothing
       is found that matches, it will be ignored
    -->
  <lib dir="solr/WEB-INF/lib/contrib/clustering/lib/" />
  启动后没有问题

9、配置IK分析器,我使用的是IKAnalyzer3.2.8 版本
将IKAnalyzer的jar包导入刚生成的项目中lib目录下,并修改其下schema.xml
<!-- IKAnalyzer3.2.8 中文分词-->
 <fieldType name="text" class="solr.TextField">
  <analyzer type="index">
   <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory"  isMaxWordLength="false"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
                <filter class="solr.LowerCaseFilterFactory"/>
        </analyzer>
        <analyzer type="query">
   <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" isMaxWordLength="true"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
                <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
                <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>  
    </fieldType>
 如果采用上面的这种方式,那么相当于我们重新定义了一种fieldType,在后面的fields中需要把那些text_general修改为text,
 为了避免这种麻烦,我们可以修改原有的text_general类型:

 找到fieldType name="text_general" ,修改其中的<tokenizer class="solr.StandardTokenizerFactory"/>为

 <tokenizer class="org.wltea.analyzer.solr.IKTokenizerFactory" isMaxWordLength="true"/>

 这样就不需要修改后面的配置了。
